The Blood of a Forest

A dead forest bleeds for years, its decomposition products flowing slowly into the soil, leached out by rains to turn tributaries as black as night. Those dark tributaries join forces, darkening streams heading inexorably to the sea. At last, the blood of the forest flows out into the surf zones, spreading a dark brown stain hundreds of yards wide, carried down shore by persistent currents.

I had been thinking about this topic for a couple of years, but was motivated to finally publish it after seeing a recent (February 10, 2021) article in Hakai Magazine, an ePub devoted to coastal environmental subjects. The title was The Environmental Threat You’ve Never Heard Of.” The lead sentence is, “It’s called Coastal Darkening, and scientists are just beginning to explore.

To quote from that article, “Coastal waters around the world are steadily growing darker. This darkening—a change in the color and clarity of the water—has the potential to cause huge problems for the ocean and its inhabitants.

Some of the causes behind ocean darkening are well understood… During heavy rains, for instance, organic matter—primarily from decaying plants and loose soil—can enter the ocean as a brown, light-blocking slurry. This process is well documented in rivers and lakes, but has largely been overlooked in coastal areas.”

In the coastal city of Panama City, Florida, entire patches of cypress forests were destroyed a few years ago, thus producing lots of decaying plant matter.

What can destroy a forest? The unstoppable force of a category 5 hurricane. In this instance, it was Hurricane Michael striking Panama City and the surrounding Florida Panhandle on October 10, 2018.

Ironically, although I had retired just days before, I attended an Office of Naval Research Workshop on diving, and had bragged to one of the attendees that Panama City was in a very lucky geographical location. We had not been hit by a hurricane since Hurricane Opal in 1995. And that was only a Category 4 hurricane.

Only a few days later, Panama City’s luck changed, horribly. Category 5 Hurricane Michael made a bee-line for Panama City, pushing a wave of water that swept away much of the community of Mexico Beach, just twelve miles east of the first landfall of Michael’s eye at Tyndall Air Force Base in Panama City.

12:30 PM Tyndall Air Force Base and its drone runway to the east is in the eye of the hurricane. Destruction to the home of the 1st Air Force was catastrophic.

The above radar imagery was captured on my iPad, using Foreflight aviation software while we safely sat in a hotel room in Birmingham, AL. The redder the color, the stronger the rainfall. Green represented low rainfall intensity near the eyewall.

12:45 PM. Callaway Bayou typically pours dark stains into St. Andrew’s Bay. The torrential downpours from passage of the red and yellow rain bands (color signifying rain intensity) would have forced even more tannins southward into the Bay. (It is unlikely that the satellite view and the radar view are synched together in time.)

After returning from our hurricane safe haven in Birmingham, AL to our damaged home on Panama City Beach, and as soon as the airspace opened up again, I surveyed some of the damage from the air. A month after the storm, areas along the Gulf Coast were closed to normal aircraft due to drones surveying the damage along Mexico Beach, and providing assistance to personnel looking for human remains. 

However, there were no restrictions to flying along the path of the hurricane, northeast of Panama City. So, on November 4th I launched in that direction and discovered that a huge swath of cypress trees had been flattened about 40 miles north of Mexico Beach. Since cypress trees love water, there were of course creeks running through the midst of them. The Florida Panhandle watershed runs inexorably south towards the Gulf of Mexico (GOM).

Fourmile Creek ran through the area I photographed. It is a tributary feeding the Chipola River. The Chipola in turn dumps into the Apalachicola River, the primary flow into Apalachicola Bay, home of the famous Apalachicola oysters.

A year or so later, as seen on Google Earth imagery of the affected area in Florida, some of the low-lying greenery began to return to the Fourmile Creek area. However, the skeletal remains of the flattened Cypress forest were still clearly evident.

My next flight was on December 18, 2018, after the coastal airspace had been opened back up to general aviation traffic. That was over two months after the hurricane hit shore.

Mexico Beach: December 18, 2018. Houses and buildings between Highway 98 and the beach had been swept off their foundations by the storm surge, and turned into kindling wood. The dark water Salt Creek on the lower left corner drained into the Gulf.
Another view of the decimated Mexico Beach. The normally crystal-clear water off the beach was dark, a residual from the hurricane.

On Sept 2, 2020, almost two years after the hurricane, I was flying from east to west along the coast, back towards Panama City. As I approached Mexico Beach, I saw a clearly defined dark area in the otherwise clear sea water. I snapped several photos as I got closer to the still struggling town. They are shown in sequence below, starting from furthest west, approaching town center.

On the beach, the El Governor Resort is on the right side of the photo.
Google Street View image reveals how high the storm surge rose at the El Governor. Image from Sept, 2019.
The worst of the staining came from a single source at the northern boundary of Mexico Beach.
Salt Creek was pouring its dark water directly into the Gulf of Mexico. Salt Creek drains an area of storm-flattened cypress only two miles north of the Mexico Beach shoreline.

The largest area of devastation of cypress forests surrounded Fourmile Creek which runs southeast before emptying into the Chipola River.

Due east of Panama City, the appropriately named Cypress Creek also empties into the Chipola River as the river feeds the Dead Lakes. In turn, the Chipola empties into the Apalachicola River southeast of Wewahitchka.

Nearer to Mexico Beach, there is yet another Cypress Creek which drains into both the Intracoastal Waterway at its northern end, and the GOM at its southern end. In the next aerial photo of Mexico Beach, Cypress Creek can be seen pouring its darkness into the ocean. Cypress Creek also drains a large swampy area of destroyed cypress trees.

The inset blowup of a dark squiggle in the sand, is an enlargement of the dark water outfall of Cypress Creek. (Curiously, Google Earth photos of the dark tannic water of Cypress Creek seems to show it emptying into both the Intracoastal Waterway to the north and the Gulf waters to the south.)

Remarkably, the greatest dark water offender on the September 2020 flyover was Salt Creek, with its outfall that lay two miles to the northwest of Cypress Creek.

Historical Perspective

Cypress trees have been in Florida for at least 6,500 years. During that time, their populations must have weathered tens of thousands of hurricanes. In spite of being knocked down due to being rooted in wet, soggy soil, and frequently rotting as a result, the overall population is well adapted to black water. Their blood, or rot if you will, produces more of the black water habitat that the cypress trees favor. Throughout the southeastern United States, Cypress forests (with isolated communities often called “domes”) remain ideal habitat for many species of fish, birds and mammals.

Tourists flock to the Gulf Coast’s so-called “Miracle Strip” of clean water and white sand that stretches from Pensacola Beach to Mexico Beach and slightly beyond. On a macro scale, the water and beaches are kept clear by the effects of the Loop Current, and its eddies, bringing clear Gulf water up towards the Gulf shores.

While the dark water periodically spilling into the normally clear Gulf of Mexico beaches may be repulsive to tourists, an experimental study described in the Haikai article notes that black water outfalls may favor certain zooplankton, providing a new food species for local fishes.

So, to this scientist at least, it may that in the Gulf of Mexico, periodic outpourings of dark water caused by heavy rains, tropical storms and hurricanes may be what is required to balance the estuary and marine ecosystem.

In other words, the concerns stated in the Haikai article may not apply to the west coast of Florida. Of course, to know for sure, further study is required.

In retrospect, when looking down upon flattened forests of trees, it seems nature is harsh. But nature works for the end game; survival of the environment. In Florida, the environment has survived hurricanes, and their effects on forests and water, for millennia.

Of greater concern to Florida might be the permanent destruction of the cypress forests by man, rather than hurricanes. Nature can recover from hurricanes, but cannot recover from man’s misguided intentions. After all, forests buffer the effects of hurricanes. Without them, Florida would lay flat and naked before every onslaught of a sometimes violent Nature.

Hydrogen Diving: The Good, The Bad, the Ugly

In the preceding blog post, I reminded the reader that the Earth’s supply of helium is limited. It is not a renewable resource.

Being a diving professional, I am not concerned about the consequence of a helium shortage on party balloons. But I am thinking about the potential consequences on diving.

So, knowing that hydrogen has both good and bad traits, it would be prudent to begin thinking about whether or not there is a way to safely substitute hydrogen for helium in technical, scientific, commercial and military diving.

Perhaps the word “bad” is too much of an understatement. Perhaps “horrible” would be a better descriptor for something like the Hindenburg disaster.

With that sobering reminder of what can happen, we now cautiously move on to the science.

First, we begin with the explosion hazard of hydrogen in binary mixtures of hydrogen and oxygen.

For diving in the 10 to 20 bar range, 326 to 653 fsw range, the upper explosion limit is 94.2 molar percent. So that means that if a binary gas mixture contains 96% hydrogen and 4% oxygen, it should not explode when ignited.

Those underlined words are important. An explosive mixture of hydrogen and oxygen will not explode without an ignition source. Proof of that is exhibited in many college introductory chemistry lectures, and documented in the following YouTube video.

Arne Zetterström

As a forecast of our potential future, during World War II, Sweden was deprived of a ready source of helium coming from the U.S. and elsewhere. So, the clever and industrious Arne Zetterström conducted a series of experimental deep, hard hat dives from 1943 to 1945 using a mixture of 96% hydrogen and 4% oxygen on dives ranging from 12 to 17 bar.

Once at depth, Zetterström switched from a non-hydrox gas mixture to the “hydrox” gas mixture. His initial test dive was to 111 msw (362 fsw, 12 bar), progressing through six dives to a maximum depth of 160 msw (522 fsw, 17 bar).

That dive series was successful. Unfortunately, on the last dive on 7 August 1945, Zetterström died tragically when his dive tenders mistakenly pulled him directly to the surface from the bottom depth of 522 fsw. He died from fulminant decompression sickness.

From the above table we see that modern measurements confirm that Zetterström chose his gas mixes wisely. At a 96 mol% of hydrogen, he was above the upper explosion limit. If there had been an unexpected ignition event, his breathing gas mixture would not have exploded.

I have confirmed the oxygen partial pressure for Zetterström’s dives using PTC Mathcad Express 3.1 and will share the process.

First, I show pressure conversions familiar to Navy divers and diving scientists, but not known to most others.

For Zetterström’s 111 msw (362 fsw) dive, the partial pressure of oxygen (PO2) would have been 0.478 atm, at the top end of the target range (0.4 to 0.48) for U.S. Navy chamber oxygen atmosphere during saturation diving. A PO2 of 0.48 is believed to be the highest PO2 tolerated for extended periods. Saturation dives sometimes last over a month.

For Zetterström’s 6th and last dive, to 160 msw (522 fsw), the oxygen partial pressure was 0.7 ata, about half of what it normally is in modern electronic rebreathers with fixed PO2.

A far more detailed story of the Zetterström Hydrox dive series can be found in this book.

Arne Zetterström Memorial Dive

In 2012, the Swedish Historical Diving Society and the Royal Institute of Technology (KTH) Diving Club, Stockholm, conducted an Arne Zetterström Memorial dive to a relatively shallow depth of 40 msw or 131 fsw. The original 96% – 4% ratio of hydrogen and oxygen was maintained, resulting in a gas mixture with a PO2 of 0.20 atm.

As reported in the KTH Dive Club’s Dykloggen (dive log) report of July 2012, the team lead was Ola Lindh, Project Leader and Diver. Åke Larsson, another diver, contributed the following information about that dive.

The Hydrox divers used open circuit scuba, with back mounted air, and for decompression, bottles of hydrox and oxygen.

The Swedish divers did not go deeper than 131 feet because they were just above the mud at that depth in a quarry. Plus, they did not yet have details of Zetterström’s decompression plan for deeper diving.

Today, they do possess the wartime hydrogen decompression plan, so deeper hydrogen dives may be forthcoming.

Three gas mixtures – hydrogen, and air (nitrogen and oxygen)

When you mix an inert gas like nitrogen (or perhaps helium?) with hydrogen and oxygen mixtures, that greatly reduces the explosion hazard. But as this video shows, sooner or later the ratios might change enough to become explosive.

Naval Medical Research Institute

I spent 12 years working as a diving biomedical researcher at the Naval Medical Research Institute (NMRI) in Bethesda, MD.

Main entrance to the Albert R. Behnke Diving Medicine Research Center, at NMRI.

My laboratory was in the Behnke Diving Medicine Research Center building, but the hyperbaric hydrogen facility was situated a safe distance behind the main building. In the unlikely event of an explosion, the main Behnke facility and its hyperbaric chamber complex would be preserved.  

The hyperbaric hydrogen facility was used to test the effects of high-pressure hydrogen and biochemical decompression on pigs, rather than risk human divers. And all of that was done safely, thanks to the professionalism of Navy divers and scientists.

Dr. Susan Kayar checking on the hydrogen diving pigs.

Kayar, a member of the Women Divers Hall of Fame, used at 230 msw (751 fsw) a gas mixture of 88% hydrogen, 2% oxygen, balance helium with a slight amount of nitrogen. That 88% hydrogen mixture put the gas mixture well above the 71.3% upper explosion limit for three gas components at 24 bar pressure. The resulting PO2 was 0.5 ata.

Compagnie Maritime d’Expertises (COMEX)

COMEX and their human-rated hyperbaric chambers are located in Marseilles, France.

When it came to manned hydrogen diving, the effect of hydrogen narcosis forced COMEX to operate below the upper explosion limit during its long series of experimental hydrogen dives.

In 1985, COMEX’s Hydra V was the first manned hydrogen dive to 450 msw. Hydrogen fraction was 54%, helium fraction was 45%, and oxygen fraction 1%. PO2 was a nominal 0.45 atm, the same partial pressure used by the U.S. Navy for saturation dives.

In 1988 during Hydra VIII, the first open water hydrogen dive, the depth was 534 msw, or 1752 fsw. Hydrogen fraction was 49%, helium fraction was 50%, and oxygen fraction 1%. The resulting oxygen partial pressure was 0.54 atmospheres.

The following video documents the record-breaking Hydra VIII dive.

The 534 msw Hydra VIII depth record was broken by Hydra X, a 701 msw, 2300 fsw chamber dive. The gas mixture was the same as in Hydra VIII, hydrogen fraction 49%, helium 50%, and oxygen percentage 1%. Due to the increase in depth, PO2 rose to 0.7 atm, an oxygen partial pressure frequently used in older U.S. Navy rebreathers.

The head of the Diving Medicine Department at NMRI, CAPT Ed Flynn, M.D. (glasses and grey hair sitting on the right side of the console), was performing physiological studies on both Hydra VI and VIII. In essence he was the Patron Saint of the NMRI Hydrogen Research Facility.

Shallow Hydrogen Diving

What have the previous studies taught us? Well, for one thing, the Swedes showed in their Arne Zetterström Memorial dive that you can get away with oxygen concentrations close to normoxia, PO2~0.21 ata. The disadvantage of normal atmospheric partial pressures of oxygen, compared to higher pressures, is related to decompression time. There is a decompression advantage when breathing oxygen pressures of 1.3 to 1.45 ata. Virtually all modern electronic rebreathers use those oxygen pressures for that reason. But as the KTH Dive Club showed, hydrogen decompression can be safely handled at relatively shallow depths.

For recreational divers, there is an economic advantage for reducing helium usage by substituting nitrogen. We don’t yet know what the economic and safety comparison would be when using helium diluted hydrogen versus pure hydrogen.

Hydrogen, helium, and oxygen were the standard gases used by COMEX. But they were likely chosen to lessen hydrogen toxicity. Hydrogen toxicity would not be a problem at shallow depth. And in fact, the KTH Dive Club reported no toxicity problems.

Retrospection

As proud as I have been of the record-breaking COMEX hydrogen research program, and of the highly imaginative U.S. Navy hydrogen research program, it has not been lost on me that the first deep human hydrogen dives were conducted by an undoubtedly low-cost program led by a single Swedish Naval Officer, Arne Zetterström.

Now, I find it remarkable that the people testing hydrogen diving at relatively shallow depths, would also be Swedish. Unlike the COMEX and NMRI projects described above, I suspect the KTH Dive club was not sponsored by multimillion dollar programs.

You have to admire the Swedish chutzpah.

The Sinking of the Montrose

“If it had been a snake, it would’ve bit me.”

That phrase is common in the Southern United States, often shouted in surprise when you’re vainly looking for something, and eventually discover it right in front of you.

Well, here’s an example of when the snake did bite, figuratively, and ended up sinking a ship.

The Ship

In 1962, the one-year-old, 5,000 ton displacement, 444-foot-long British freighter, the M/V Montrose, entered the Great Lakes after its fifth transatlantic voyage from its homeport of London, England. 

On June 30, 1962, it was docked at the Detroit Harbor Terminal taking on 200 tons of aluminum. Once the ship was fully loaded, a Canadian Great Lakes pilot boarded the ship at night to guide the vessel through the Detroit River, north towards Lake St. Clair and the other Great Lakes.

The River

The Detroit River connects Lake Erie at its southern end and runs generally northeast approximately 28 miles to Lake St. Clair at the north. It is bordered by Canada’s Ontario Province on the eastern side and Michigan in the United States on the opposite bank. The river’s strong current runs to the south towards Lake Erie.

The Collision

Now, imagine the chagrin of the Canadian pilot as he guided the vessel across the downside shipping lane to reach the upside lane on the Canadian side of the river. That course took it directly into the path of a heavily loaded barge on the American side, heading down the Detroit River. The resulting collision ripped a 48-foot long and as much as 24-feet wide gash in the ship’s port side bow.

The freighter immediately started flooding at the bow, soon raising the rudder and propellers out of the water. With no way to control the sinking ship, the crew and ship drifted in the strong Detroit River current, before running aground beneath the Ambassador Bridge connecting Detroit with the Canadian city of Windsor, Ontario.

The Montrose as it was foundering. Water was pouring in through a large gash in the bow’s port side.

This expensive mistake occurred in July, 1962, and I was there to record the aftermath, as were thousands of other onlookers. The links to other photos and videos are found below.

A fuzzy photo I took as a Bob-Lo excursion boat was moving past the starboard hull of the Montrose. The port side settled on the river bottom 35-feet down.

Sharper photos were taken by various civilians and published in the following link.

https://www.detroityes.com/mb/showthread.php?12005-1962-Ship-capsized-in-Detroit-River-under-Ambassador-also-gas-storage-tanks

A better photo of the starboard hull taken from a Bob-Lo boat approaching close to the wreck.
Photo taken from the opposite shore. About a third of the ship’s deck and superstructure is visible.

I imagine that salvage or other commercial divers were required to inspect the hull and attach lifting cables at the appropriate points. Typically, they might have wanted to weld patching plates over the huge gash in the hull. But the ship lay on its damaged side, so no patches could be applied until the ship was righted.

View of the stern of the wreck from the Ambassador Bridge connecting the U.S. and Canada.

I wish I had those divers’ stories, but so far, I haven’t found any. Salvage divers tend not to talk about their arduous, risky, and sometimes horrifying work. Fortunately, this time there were no casualties. Every crew member on both vessels was rescued, having suffered minimal injuries.

The salvage plan involved righting and raising the vessel using large floating cranes on barges. Frankly, I cannot imagine the load on those lifting cables. But as you can see in following photo, there were many cables attached to the bow preventing the ship from drifting further down current. They likely helped stabilize the craft once the bow was partially above water.

The ship after the bow had been partially raised.

No doubt a great deal of engineering calculations (and maybe educated guesses?) went into determining the number and placement of those cables. Salvage engineering is a torturous task, with calculations at that time being done by hand or using a slip stick (slide rule).

Below is a National Museum of American History slide rule identical to my personal Pickett slide rule, Model N1010-ES Trig. A similar slide rule accompanied the Apollo astronauts to the moon.

Digital calculators and computers were not readily available in 1962.

The following link is from the Lake Shore Guardian, and contains ample details of the accident. It is an interesting account. http://www.lakeshoreguardian.com/site/news/1037/MV-Montrose#.YDgVd-hKiUk

Analysis

So, how could highly experienced and qualified seamen drive their ship at full speed directly into the path of a well-lighted barge, as was reported by the ensuing investigation?

The Lakeshore Guardian report does not give it a name, but I will: “cognitive blindness.” Cognitive blindness in trained and alert individuals often occurs when people are distracted. In this case, that distraction was another freighter pulling into the same berth the Montrose was attempting to vacate. The Montrose pilot made all ahead full to keep a safe separation from the ship coming in close behind it.

In their distracted state, they did not see the navigation lights from the oncoming barge, did not hear the barge’s warning whistles and horn blasts, and never responded with their own emergency signal until the last second. By then, it was too late to slow their ship, or dodge the barge.

Cognitive blindness caused by distraction has caused old and experienced automobile drivers to pull directly in front of oncoming vehicles. One such fatal accident occurred at an intersection my wife and I frequently traverse. The driver was physically capable of seeing the oncoming traffic, but in that and similar cases, their brain must not have recognized the danger.

In the link below, the U.S. radio program NPR interviewed Christopher Chabris and Daniel Simmons about their book, named after the psychologist’s invisible gorilla test. 

https://www.npr.org/templates/story/story.php?storyId=129934804

The two psychologists had subjects watch a basketball game. Subjects were instructed to keep track of the number of ball passes between players. However, that objective was a distraction. The researchers really wanted to know if their research subjects noticed a man in a gorilla suit walking across the court. Remarkably, more than 50% of the test subjects never saw the gorilla.

A distraction while watching a video may be harmless, but a distraction while piloting a 5,000 ton vessel can, and was, disastrous. Luckily, no lives were lost, that time.

Among the multitude of other writings about the potential effect of distractions, is a new book on human factors.

While the work of Gareth Lock is focused on diving, the psychological factors it discusses apply across all disciplines, including seamanship. Chapter 7, Situational Awareness, has an interesting and relevant sub title: “Just because it’s there, it doesn’t mean you’ve recognized its significance.”

In summary, the deleterious effect of cognitive blindness can be found in all disciplines, including combat, aviation, diving, driving, space and seafaring.

As they say in combat, “The enemy you don’t see is the one that will kill you.”

The highlighted image at the top of this post is from the Walter P. Reuther Library at Wayne State University. http://reuther.wayne.edu/node/4331

“Capt. Ralph Eyre-Walker stands on the side of his wrecked British freighter, ‘The Montrose’. The freighter collided with a cement barge and sank in the Detroit River just downstream of the Ambassador Bridge, Detroit, Michigan.”

Photographer’s (Tony Spina) note: “I rode out with the captain the next day so he could get some of his belongings and captured this shot.”

Canoeing the Little Nianqua River in the Ozarks

“Nianqua” means “many springs” in the Osage language. It’s those little springs that make canoeing down the Little Nianqua river a favorite pastime for adventurers. The Little Nianqua is a tributary of the Nianqua River which empties into the Mississisppi.

In between freshman and sophomore year in college (September of 1966), a high school friend from the Presbyterian Church near our home in Kansas City, KS, suggested we take a canoe trip in the Ozarks about 150 miles southeast of Kansas City.

The portion of the Little Nianqua normally canoed is about 35 miles, and with time out for climbing the over-looming bluffs, visiting Osage sites and generally goofing around, we would have to spend the night sleeping on a sandbar, propping the canoe over us for protection. It sounded like great fun.

A photo of me canoeing while Richard Thorn photographed from a sand bar.

Here was the goofing around part. I made an emergency outrigger out of a barrel and some limbs.

It sort of worked.  At least it didn’t sink.

Improvised overnight accommodations.
Richard on the lookout for girls. He didn’t find any.

Those bluffs were pretty high, but of course we felt compelled to climb them.

Below is a view of our sandbar encampment from the bluff.

Apparently, Richard was not aware that the spirit of the departed Osage do not like to be disturbed. Otherwise, he would not have perched on an Osage burial mound.

Richard tempting fate.

Spirits Revenge

Shortly after we returned home, Richard and I borrowed my family’s 55 Buick Special and went to a drive in. I was almost 21 years old, so I felt inspired to procure a gallon of Ripple wine. I have no idea what the movie was about, but Ripple actually tasted better than its reputation.

Unfortunately, the spirits of the Osage decided at that moment to seek their revenge. Richard spilled half of the gallon of Ripple, inside the Buick.

Our feeble attempt to soak up the wine and clean the interior was of no avail. No matter what we did, the car stank of cheap wine.

As luck would have it, we both had to head back to college almost immediately. As soon as I was back in Georgia, my parents  traded in their one and only car. Somehow, I doubt they got much for it.

I lost touch with Richard Thorn when my parents sold the house in Prairie Village, threw out my child-hood toys (for spite maybe?), hopped into their station wagon with that fresh, new car smell, and headed to a warmer clime, southeast Texas.

Strangely enough, they never said anything to me about that Ripple event. But I guess, compared to my flying off with the keys to the Buick when I flew back to Atlanta the previous January, without enough gas in the car for Dad to make it home, and having poor Dad walk to a gas station, in a snowstorm, well, the Ripple event simply paled in comparison.

However, that “no-keys event”, they did tell me about.

I guess the lesson is, respect the spirits of the dead, or you will pay in ways you cannot imagine.

Perhaps you have read about the Osage in my novels. The Osage ancestral lands were located in Missouri around the Ozarks and over to the Mississippi River. Reportedly, French fur traders found the Osage women to be quite attractive. So much so that supposedly, many of the traders married Osage women.

A young Osage mother and child.

In spite of that intermarriage, when land-hungry settlers moved from Tennessee to Arkansas and Missouri, the government relocated the Osage to Oklahoma, right next to the relocated Cherokees. In fact, to this day, Pawhuska, Oklahoma, a town I’ve visited and written about, is the current home of the Osage Nation.

About the only Osage thing the white man did not replace, was the name of their river in Missouri, the Nianqua.

In summary, if you’re so inclined, have fun canoeing the Little Niangua. But do be careful where you tread.

Autohemotherapy Saved My Brother

In 1940, my older brother, Albert, was born prematurely, with a severe case of ichthyosis (skin with scales like fish.)

Due to Albert’s prematurity, at birth his entire body fit in the palm of my father’s hand. Albert had no suckling reflex, and so the pediatrician said there was nothing that could be done to save him. The newborn was doomed.

Based on the above information, I would place the baby’s fetal development at roughly 2/3rds of the way through the second trimester, perhaps at 22 weeks, close to a pound in weight and at most eight inches from the top of his head to his rump. He would have been below the now standard 24 week “age of survivability.” Survival at that stage of prematurity was unlikely.

Dr. Albert S.J. Clarke, an orthopedic surgeon, was my Dad. The infant at risk was Dad’s first child, named after him (Albert Sidney Johnston Clarke III.) Being a physician, Dad was not going to give up on his son without a fight.

Due to Albert’s small size, and the condition of his skin, they were unable to start an I.V., which is the standard of care in today’s medical world. So, as my Mother explained it, as a last resort, Dad withdrew his own blood and injected it into the gluteal muscles of the baby. That blood carried nutrition and sustenance to Albert; e.g., water, minerals, protein, sugar.

That was not as crazy as it seems, since Autohemotherapy was used in the early 20th century to treat dermatological cases, starting in 1913. The following abstract is an example of a 1928 article after the method gained some medical acceptance.

Quoting from the abstract, “Autohemotherapy, first used in dermatologic conditions by Ravaut (1913), closely followed by Spiethoff (1913), consists in the withdrawal of blood … and its injection into the patient’s gluteal muscles, preferably.”

By the 1940’s, Dr. Clarke was no doubt aware of the questionable therapeutic efficacy of the old method, but as a means of delivering fluid and nutrition to an infant otherwise shut-off from the world, there was nothing to lose. Their blood types matched, so in theory, a blood injection would not hurt.

Although the Rh factor was just discovered that year (1940), Albert’s odds of survival were likely assured by the fact that most people are Rh positive.

At the beginning of the 20th century, there was virtually no standard of care for premature infants. Julius H. Hess (1876–1955) published the first book on the subject of medical care for the premature infant in 1922.

In that book, Hess described tube feeding, or gavage, as in the illustration below. However, in the following years, infants often died from aspiration pneumonia induced by early feeding after birth, and early-applied gavage fell out of favor.

A year after my father successfully salvaged my brother, Hess amended his guidance in his 1941 text, writing “Small premature babies (those weighing under 1200 g) were not fed for 24–48 h …. During this time the premature baby receives physiologic salt solution, subcutaneously in the thighs, one to three times daily.”

Obviously, physiological saline solution avoids the risk of incompatible blood reactions, but in the case of that baby and his father-physician, God had blessed them with fully compatible blood types.

I don’t know if Hess had been made aware of my Dad’s lifesaving treatment conducted a year before Hess made his latest recommendation, but that is certainly possible.

I never discussed with Dad the details of his saving intervention, but from what I’ve read about babies with ichthyosis, my brother’s survival and thriving until age 73 is a bit of a miracle. His pediatricians gave him zero chance of surviving his first days. They didn’t know just how determined my Father could be.

Due to my brother’s genetic skin disease, he shed skin in large flakes; his bed sheets were always covered in them. He had to be lathered in Vaseline to keep his brittle skin from cracking too deeply, and bleeding. He also had very poor tolerance to heat because he had few if any functioning sweat glands.

In spite of his disability, Albert was one of the nation’s first Respiratory Therapists. He trained other Respiratory Therapists in west coast colleges, and ran several Respiratory Therapy Departments in hospitals across the country.

With unlimited medical research libraries at his disposal, he discovered on his own that a drug used for treating psoriasis helped him control his own skin condition. As a result, his quality of life in his last decades greatly improved. He fulfilled a dream of remarrying, all made possible by a determined physician willing to take a chance when the “experts” had given up hope.

Today, thanks to advances in the medical management of premature infants, autohemotherapy is medically unnecessary. In fact, many doubters question its efficacy. However, I have the physical scars from growing up with a rambunctious big brother to prove that, in at least one case, it was a lifesaver.

Where is Pham-lỷ-Täi?

The word “pen pals” was recently in the news.

In the 1960s, students were taught U.S and World History. Long before the days of personal computers and the Internet, we high school students were encouraged to expand our perspective by becoming pen pals with other students around the world.

Of course, back then, the phrase “pen pal” literally meant using a pen to write, preferably in cursive or some reasonable facsimile.

Perhaps it was through the Weekly Reader that I first exchanged mail and photos with a gorgeous blond girl from Denmark. But by far the most memorable, and longest lasting pen pal relationship, was with a student from Saigon (later renamed Ho Chi Minh City.)

Pham-lỷ-Täi was a Vietnamese school boy with precisely written English. He told me that he and his family were Catholic. They lived in Saigon where his father worked for the South Vietnamese government, if I remember correctly.

As we wrote, we exchanged bits of national culture. He sent me a tall doll of a Vietnamese woman in long silk dress and hat (the Asian conical Nón lá). But as the years progressed, our written conversation turned more serious, towards the growing signs of war.

In 1964 as I was nearing graduation from Shawnee Mission East High School, in Prairie Village, Kansas, there were thousands of U.S. advisers in South Vietnam. The August 1964 Gulf of Tonkin incident had not yet happened, so while Pham-lỷ-Täi was uneasy, outright hostilities had not yet broken out.

However, about the time I left home for college in September, the letter chain was broken, and fighting began in earnest.

As history revealed, the war did not end well for either American and allied troops (Australia, New Zealand, and other forces), or the people of South Vietnam. Democracy was crushed. For well-educated Christians in government service, the consequences were more dire.

Communists seek out the best educated and most pious people, and kill them. That is what communist revolutions invariably do. Indeed, it is a sobering exercise to research the numbers of national citizens killed by Mao, Stalin, and Pol Pot’s Khmer Rouge. There were literally millions of citizens killed in each communist revolution.

I was in Army training in 1975 with a Cambodian officer at the beginning of the genocide of the Cambodian people by the Communist Khmer Rouge. Our class of American Officers urged the young man to stay in the country, fearing he would be killed if he returned home. But sadly, out of duty to his nation and to his family, he refused to stay in the U.S.

There is no doubt that his skull is one of the many skulls found in Pol Pot’s killing fields.

Pham ly Tai’s fate was less certain. Did he take up arms to lead the defense of his country? Did he perish in combat? Did he perhaps escape by boat, like my family physician, Dzung Nguyen, did as a child?

Was his family perhaps given diplomatic escort out of Saigon on the last American helicopters out?

I don’t know. If anyone does know, I would greatly appreciate hearing, one way or the other.

However, my fear is that like my Cambodian officer friend, duty kept Pham-lỷ-Täi home to face the onslaught.

For a long time, I had forgotten about my old pen pal. However, many decades later I was on a Taiwanese airline, Eva Air, headed to Taipei and eventually, Bangkok. This particular Eva Air flight had an odd Hello Kitty theme, inside and out. It catered to children. Strangely, I found myself surrounded by youngsters from Vietnam returning from Los Angeles and Disney World during their summer break.

In the seat next to me was a young lady from Ho Chi Minh City, and across the aisle were her female classmates. She no doubt noticed I was an American male of an age which could have placed me in Vietnam during the war. Apparently, that worried her. So, as the flight leveled off at altitude, my seatmate broke the ice by asking in her best English only one sentence.

“Are you mad?”

Seeing real concern in her eyes, and sensing a memory of things she might have heard about the war, I answered, “No, I am not mad.”

There were many more things I could have asked, such as, “Are you mad?” But her English was faltering, and my Vietnamese was non-existent. What I was thinking at that point was far too complex to speak simply. So, my answer, “No, I am not mad,” was the only way I could answer her curious question.

For sure, I could not be mad at a child who was not even alive during the Vietnam war. She and her friends had nothing to do with what happened to her countrymen, and ours.

From a different perspective, I wondered how my friends who were in combat in Vietnam would have answered. But I suspect, being good men and women all, they would not have held a grudge for half a lifetime. War is hell, but only the Communist leaders directed the killing of those who opposed them, for political purposes. The children are innocent.

I thought about telling that girl, maybe fifteen years of age, how I used to have a friend in Saigon, a boy about her age. If Pham-lỷ-Täi lived, perhaps he would have a granddaughter about her age. I wished, insanely I suppose, that the girl in the seat beside me was one of his granddaughters. If so, then I would know he survived.

But, for some reason, I did not ask her.

It’s strange the things you think about when crossing large oceans.

Once in Taipei, I was pleasantly surprised to see my former seatmate with her school friends looking my way, all smiles and giggles. They seemed to be pleased to meet an American of my generation who was not mad at them.

Of course I was not mad at a child. I never could be.

But I did remember a Vietnamese boy I knew a long time ago. He seemed to be a natural leader, a potential politician with strong ethics, a young man who would face death to save his country from communism.

So, I still wonder, what happened to my pen pal, Pham-lỷ-Täi?

In February of 2021, I came across the movie, Ride the Thunder- A Vietnam War Story of Victory and Betrayal. To my taste, the acting is a bit melodramatic, but I do believe I have a better understanding of what might have happened to my friend. If he and his family had not been killed outright by the Communists, he might had suffered a fate worse than death, Communist reeducation camps. The movie and book has been praised for telling the brutal truth. And apparently, the most compelling truth is revealed by  Major Le La Binh, a South Vietnamese officer who after the war was held in those “reeducation camps.”

Sadly, that newly revealed ending of the Vietnam war does not bode well for my friend, Pham-lỷ-Täi.

The Basic Chemistry of Nitrogen Dioxide

“The U.S. President was on the phone with the President of China when a video from the International Space Station came in from the NASA feed to the Emergency Operations Center. A huge burnt-orange cloud was covering the entire southern Pacific, extending all the way up to Hawaii and down to New Zealand. This was no ordinary nuclear explosion.”

The recent deadly explosion in Beirut, and the science fiction thriller, Atmosphere, book 3 of the Jason Parker Trilogy, both involve a toxic, brownish-orange gas, nitrogen dioxide. Of course, one involvement is fictional, and the other, sadly, is not.

From the first chapter of Atmosphere, we find a description of the effects of a gamma ray burst hitting the Earth. “Rampaging winds began spreading toxic nitrogen dioxide clouds around the planet, and within days, the earth was fully affected.”

Considering the violence with which nitrogen dioxide is associated, the way it is created is relatively simple. Some chemists will no doubt claim that the following discussion is too simplistic, but I’ll let them fill in the blanks, if they so choose. As advertised, this is just the basics.

Given enough energy, and localized temperatures on the order of 3000°C, nitrogen molecules (two atoms of nitrogen, N2) combine with oxygen molecules (two atoms of oxygen, O2) to form a chemically unstable gas, nitric oxide, NO.

In chemical terms, N2 + O2 → 2NO

If the searing NO gas is cooled rapidly in the presence of oxygen molecules, the toxic, brownish-orange gas, nitrogen dioxide, is formed.

2NO + O2 → 2NO2.  (This is really nasty stuff!)

It’s been known since at least 1911 that the temperature of an electrical arc (6000° – 8000°C) is enough to cause N2 and O2 to form NO. If the hot gaseous NO is then rapidly cooled, NO2 results.

In the science fiction novel, NO2 was created high in the atmosphere by a cosmic burst of high energy gamma rays (GRB) colliding with nitrogen molecules in the presence of oxygen. Lightning also creates nitrogen dioxide, although in relatively small quantities. But if you increase the energy and the quantity of nitrogen and oxygen, “a huge burnt-orange cloud” would be formed.  

According to current estimates, that is exactly what happened in Beirut.

Apparently, an industrial fire caused the thermal decomposition of large quantities of ammonium nitrate, which energetically broke down to form massive quantities of nitrogen gas, oxygen and water.

2NH4NO3 → 2N2 + 4H2O + O2.

The resulting high temperature N2 and O2 instantly combined to form the toxic burnt orange cloud of nitrogen dioxide, as seen in the above photo.

The exact mechanism of NO2 formation likely differs among the progenitor sources (GRB, lightning, explosion), but the basics should be the same.

What happened to the poisonous cloud of NO2 after it formed? Unlike what would happen in the upper atmosphere during a GRB, near the surface there is enough moisture for the NO2 to quickly combine with water to form nitric acid.

3 NO2 + H2O → 2 HNO3 + NO

Nitric acid rain would not be pleasant, but would not be as bad as nitrogen dioxide.

So, imagine if you will, a cosmic event (a GRB) far more violent than any man-made explosion. Imagine the entire atmosphere turning into a cloud like that in the photo above. Arguably, that is what would happen after a devastating GRB from within our galaxy.

Actually, that toxic nitrogen dioxide cloud would be the least of the planet’s troubles. It would be a very bad day on Earth.

The good news is that such an event would be very unlikely.

But then again, this is 2020.

Cereal Was Almost the Death of Me

This year, 2017, marks the 120th year that Grape Nuts cereal has been in existence. Generations have been raised on it, and as the 1921 ad would suggest, it seems to help little bodies grow big and strong. As the Post company says, “There’s a Reason” for the cereal’s success.

However, through some weird quirk, some random juxtaposition of breath and nerves, a single, tiny particle of this delicious blend of barley and wheat almost killed me.

Or so it seemed at the time.

I consider Grape Nuts part of a paleo diet, of sorts. As cereals go, it’s primitive. It is merely ground bits of grain that never needed to be squeezed into flakes, or coated with sugar or artificial flavorings. For me, it’s like getting back to the basics of breakfast, or in this particular case, an evening snack.

On the night of my close call, while my wife was watching TV, I settled into my home office to edit my newest book while I snacked on a demi-bowl of Grape Nuts, wet with skim milk.

No doubt your parents lectured you repeatedly about the dangers of talking with food in your mouth. Well, in adherence to my parent’s scolding, I was not talking when it happened. I was quietly reading, and breathing.

And then, in an instant, I could not breathe, at all. I could not speak or yell out. I could not swear, or call for help. No air could enter or leave my lungs.

As I looked to the doorway, terrified, half hoping for my guardian angel to appear and magically save me, I realized that if I didn’t do something, quick, I would die. I was most unexpectedly suffocating.

I stood up, planning to head to the bathroom out of some strange thought that it might be my salvation, or at least an easier place to clean up the vomitus mess or whatever else follows death by asphyxiation. And as I reached the door frame a scant twelve feet away from where I’d been sitting, I could feel myself becoming faint.

This could not be happening. What an inglorious way to die.

With all the fortitude I could muster, I was determined to make it into the bathroom before I passed out. A second later, I was bent over a sink, supporting my upper body with my hands, trying with all my might to pull air into my lungs.

Finally, I found that with almost superhuman effort I could squeeze a little air through whatever was blocking its flow. The result was a high pitched nonhuman sounding squeal, a falsetto screech higher than even a little girl can produce. Physicians call it stridor, which sounds like this.

But at least it was something. Again and again I managed to suck in just enough air to keep me alive, one loud screech after another.

In the meanwhile, my greatly concerned wife was asking, “Are you OK, are you OK?”

No, I was not at all OK, but I could not communicate that fact, other than to make that hellish shriek. But with each shriek a few more oxygen molecules entered my oxygen-starved lungs.

And as the fog of impending collapse slowly began to clear, I was finally able to cough.

After that cough, there lay in the sink a tiny granule of cereal, presumably the little spec that landed in a sensitive spot in my larynx or “voice box”, triggering the spasm which tightly closed my vocal cords. With the cords, or more properly “vocal folds”, closed, air cannot enter the lungs. 

Under normal conditions, a person can hold their breath for two to three minutes without losing consciousness. But as I later analyzed what had happened, I realized that the particle of cereal was most likely sucked into my airway when I was just beginning to inhale, at the bottom of my “tidal volume.” So my lungs were not full of air.

Logically, when involuntarily holding your breath with lungs only partially inflated, the 2-3 minute rule may not apply. So, there was a chance that I was about to lose consciousness from hypoxia.

As I later discovered, laryngeal spasm is short-lived, and resolves within a few minutes, leaving the terrified victim shocked but relieved to be able to breathe again.

The aftermath of this incident was that I now realize how little we appreciate the simple act of breathing. For our entire lives we never think about it. It just happens.

Until it doesn’t.

 

I still enjoy my Grape Nuts, and highly recommend it to anyone looking for the simple pleasures of life. But at the same time, I’m now a little more careful when I’m eating, especially if my attention is directed towards something else. Multitasking while eating can be scary.

 

Living Off Universal Energy. Really?

By stuart Burns from Erith, England (_MG_7185 Uploaded by snowmanradio), via Wikimedia Commons

I thought I was misreading the title of the news article. I adjusted my glasses, then looked again.

Sure enough, the news headlines this past week actually reported on a young couple, reportedly a Breatharian couple, who claimed they had no need for food. They lived off of Universal energy, whatever that is. Most amazingly, the news-hungry press actually reported the story, obviously without a bit of fact checking.

As a physiologist, I know that is a patently ridiculous claim. It is impossible for humans to survive without eating. And as a science fiction author, I know it is not even good science fiction. The best science fiction maintains at least a little scientific accuracy.

Could it be fantasy? Maybe, but the story was reported as being true, with no hint of tongue-in-cheek.

However, it did remind me of a revelation of sorts from a few months ago, coming to me in a split second after a quick glance to the side of the road. What attracted my attention as I passed by at 55 miles per hour was a gorgeous white egret, like the one pictured, foraging for frogs and tadpoles in a ditch recently filled to overflowing with water from several days of downpours.

And then it struck me: wouldn’t it be nice if things did not have to die so that other things can live?

Now that’s a fantasy for you. Of course life is predicated upon death. Big animals eat smaller and weaker animals. Physicality cannot exist without death; you cannot live in the body unless something else dies. That’s life, pure and simple. It sucks to be the little guy.

But what about after life? Well, at the risk of turning in my scientific credentials, I will admit I do believe in an after-life, Heaven if you will, for reasons which I will not go into here. But it struck me in that brief moment of observing a beautiful bird, that only in a spiritual realm could energy exist without the simultaneous extinguishment of life.

To my way of thinking, that may be the single greatest distinction between the spiritual realm and the physical realm.

So thank-you Breatharian couple, practitioners of Inedia, for helping me remember my roadside revelation. Perhaps there is a place in some alien realm where beautiful birds, and beautiful frogs, and even humans can coexist without one eating the other. Maybe there is some parallel universe where our laws of physics don’t apply.

Perhaps we will someday discover that parallel universe, and call it Heaven.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

DNA: A Matter of Trust

In combat, we trust our buddies with our lives. We have their back and they have ours. When submitting to surgery, we trust the medical team with our lives, and usually that trust is not betrayed. But should we be willing to trust strangers with our very essence, our DNA?

Recently I was trying to solve a plot problem in the science fiction thriller, Triangle. The storyline relied on a particular individual being singled out by the government for monitoring, not for what he had done, but for who he was.

After finishing the novel, I went back to tie up loose ends in the plot. One such loose end involved a question: How could the government know that this one person out of millions had an unrecognized super power? He was a main character in the book and so I could not ignore that question. Certainly it helps the reader suspend disbelief if the plot elements are plausible, at least superficially.

I did not have to puzzle over that question very long before an advertisement for Ancestry DNA popped up on my computer screen.

That was it!

And so the following text flowed quickly.

The characters in this conversation are Sally Simpkin  (AKA Pippi Longstocking) and Joshua Nilsson, identified below by their initials. She was trying to explain to Nilsson why she and her employers had been monitoring him.

SS: “[The government] detected that you had a high probability of having certain prescient capabilities.”
JN: “Forgive me for being a bit skeptical. Why can’t you tell me [how]?”
SS: “I’m not even cleared to know the process. I just took the assignment. It had something to do with a DNA sample you submitted.”
JN: “DNA? The only DNA I’ve submitted was for genealogy research.”

Triangle was published on May 21, 2017. On May 25, the following BBC headline appeared in my browser.

Ancestry.com denies exploiting users’ DNA. “A leading genealogy service, Ancestry.com, has denied exploiting users’ DNA following criticism of its terms and conditions.”

So, is this author also prescient like Nilsson? Or is this blogger merely a bit jaded.

Genealogy services have a difficult time competing in the world market. After all, there are only so many retired folks trying to trace their family history and solidify their genetic place in the world before their demise. Speaking for myself, I started my genealogy research years ago, picking it up from my grandmothers who told tales of Civil War Colonels and Carpet Bagger treachery, and murder. In fact, I’ve posted on this blog before about some of my discoveries.

With the advent of computers and the availability of free records from the Mormon Church, the ease of doing genealogical research exploded. Some of the software and services were either free or inexpensive. Of course, “free” doesn’t do much for a service provider’s cash flow. So, into each CEO’s mind comes, sooner or later, thoughts of monetization. How could Facebook’s Zuckerberg and others turn a free service into something that can make them gazillions? In the case of genealogy services, they started by charging a monthly access fee, and in one case, by enticing viewers to keep paying fees by waving images of fig leaves to attract their attention. That was a strange but brilliant ploy that worked very well on this researcher.

The next step in monetization is now universal: sell ads to companies who want access to the growing body of amateur genealogists. The final ploy, and by far the most ethically troubling, is selling information about users of computer services. First there were those pesky cookies, but now there is blood, or saliva more exactly.

For some companies, it is not enough to know what users search for. There is now a market for information about who you are, your very genetic essence, which is hidden even to you. But some companies like 23andme, Ancestry, MyHeritage, GPS Origins, Living DNA, and Family Tree DNA, let you take a peek into your genes, for a price.

The ironic thing is, this most personal information is not only freely given, but people actually pay the DNA harvesters to harvest their most sacred self. And of course, once that has been done, your genetic-identity can be sold (read the fine pint). While we are urged to protect ourselves from identity theft, isn’t it odd that we are at the same time being enticed into giving away our most precious identity of all, our DNA? And we seem to be doing so gladly, blithely unaware of the implications for us and our progeny.

But don’t let the natural skeptic in me show through too strongly. I do, after all, have faith that everything we’re being asked to store in the “cloud” is actually as secure as cloud storage facilities (whatever those are) claim. And I’m sure the secrets buried deep in our genes are forever kept private, and safe from hackers.

But then, there is that troubling Orwellian Consent Form.

Oh well, Sally Simpkin’s monitoring assignment in Triangle is purely fictional. Surely, no government would really have an interest in our genes.

Or would it?
