Climate Change, Algae Blooms, Anoxic Waters and Dead Dolphins: What’s Killing East Coast Dolphins? Morbillivirus? Or Something More Ominous?

Because dolphins sit at the top of most ocean food chains and due to their sensitivity to healthy or unhealthy ocean states, they have been called “the sentinels of ocean health” by oceanographers around the world. So, when East Coast dolphins are dying at their fastest rate in 26 years, and with scores of these majestic creatures washing up on beaches from Virginia Beach to New York, we should sit up and pay attention.


I remember the 1987 East Coast dolphin die-off well. Why? Because I can clearly recall paddling through the ugly, murky red-stained waters in my almost daily surfing quest for decent waves as a Virginia Beach teenager. It was early September and school was just beginning. The tropical Atlantic was unloading its guns, firing off the tropical storms and hurricanes that provided the lovely swells I hunted with so much passion.

But walking down the beach didn’t provide its usual pleasure. The air was chill and the ocean ugly. Plunging into the water, I noticed it was filled with what appeared to be a reddish mud. Even knee deep, I couldn’t see my feet. Paddling out through the dark, rust-red waters was strange, eerie, like entering a distant land or the seascape of another time. The water was cold and nutrient-rich from a large upwelling event as well as from the annual run-off from farms and lawns. Distantly, I knew these things from news reports and from the discussions of family members who were, even then, heavily involved in the Chesapeake Bay Foundation’s efforts to preserve the health of marine environments local to my area.

But paddling through those ugly waters, I was more concerned about what I couldn’t see. About what was concealed beneath all the darkness and murk. Where had the crystalline waves of my early youth gone? And what of the azure waters full of rich, white foam? Now turned to a kind of brownish scum.

The waves that day were large, dark, bullies filled with a biting ugliness. Angry brutes capped with rusty foam. One held me under for longer than I liked and I turned to paddle home. Settling in front of the TV glow with my family, I learned the news. “Largest Red Tide on Record. Massive East Coast Dolphin Deaths. Health Risk. Advised to Stay out of Red-Brown and/or Murky Water.”

My family kind of laughed it off. There’d been red tides before. But none like this one. That year the red tides were exceptionally strong and over a ten month period more than 700 dolphins died.


These events of long ago remain clear in my mind because they had ominous implications for my favorite sport — surfing — which in itself was rooted in a joy for the glory of nature. I had often felt that the great symphony of life and beauty I found in the ocean while surfing contained far more majesty and spirituality than any land-bound church. The great blue vault of heaven and the starry night that came behind contained all the awe and adoration, for me, that so many others associated with God. My worship was a dance across the beautiful face of nature, my only remaining contact with the human world — the opalescent surf board beneath my feet.

But with the red tides the beauty and the awe was ripped away, revealing a dark and ugly underbelly. A soulless place of lost life and beauty. I didn’t want to plunge myself into ugly and potentially harmful waters, nor did I find much appeal in those new, dark, blood colored waves. They had lost their grace, becoming rough, brutish things and the water I was paddling through was death. Along with the dolphins, fish, crabs, every sort of sea life suffered and perished. The catches of fishermen dwindled. It was a bad year, but only a shade of things to come.


Silence and an incapacity to communicate or understand what is wrong is often the most brutal form of suffering. During my middle-school and high school years, I suffered numerous bouts of bronchitis and general weakness. During late high school, I went through a six month period when I experienced terrifying episodes of shortness of breath, with no other symptoms. Doctors couldn’t discover anything wrong, so I continued on as I could. The summer after my senior year, I was sick with a fever of 100+ for a month straight. The doctors tested me for mono and found nothing. Shrugging their shoulders, they proclaimed it was a ‘mono-like-virus.’ Whatever had caused these symptoms left my organs inflamed and my doctors advised me to ‘avoid any kind of strenuous sport or heavy lifting’ lest it cause an organ rupture. For more than a year, I required 10 hours of sleep to maintain any level of energy. Eventually, though, the health troubles and symptoms faded.


Thunderstorm over Jane Island.

Thunderstorm over Jane Island.

I come from a place that relies on the life of the ocean and the waterways that feed her. And my experiences have taught me to be sensitive and to pay attention to my surroundings. Often, the media cannot be relied upon to tell the whole story. Such was the case with the camping trip I took to Jane Island with my wife this summer.

The Jane Island campground is a thin strip of coastal pinewood carved into a cluster of sites for campers, RVers and wildlife enthusiasts. It is managed by the park service and sits adjacent to a sprawling wetland called Jane Island. The island is, itself, a testiment to the ravages of human caused climate change. More than a hundred years ago, the island hosted a fish cannery, and a number of farms. But the low lying land, like so many Chesapeake Bay Islands, has steadily been reclaimed by rising water. Now all that remains are a few copses of pine trees and a vast wetland filled with channels deep enough to kayak through. At high tide, the majority of the island is now submerged.

The nearby town of Crisfield had its own tale to tell. Dilapidated and abandoned houses lined the road leading into a town filled with closed store fronts covered in peeling or salt-stained paint. The architecture there appeared to have frozen sometime between the late 80s and late 90s. Everywhere could still be seen the icon of Crisfield — images and silhouettes of Chesapeake Bay blue crabs displayed everywhere from flags bearing school mascots (“Go Crisfield Crabs!”), to flags displayed outside dilapidated real estate offices, to paintings on the sides of buildings, to signs on the dwindling number of bay side restaurants. A ferry that transported tourists and sightseers to Tangier Island, which is also steadily being reclaimed by the Bay, lies roped off and idle, blocked by large orange traffic cones.

The scene is one of a town that is descending into a post apocalyptica, one more likely to be featured in a gritty novel or Hollywood movie than as a destination spot for vacation goers.

What had pushed Crisfield so far down the road to disintegration? One need look no further than their iconic blue crab. Crisfield is a town almost entirely supported by its crab and oyster fishing industries. But over the past 26 years, both crabs and oysters have suffered from a series of disasters. Red tides, algae blooms, anoxia, invasive species, and chemical dumps from industries along rivers feeding the bay all exacted their awful toll. The result was numerous deaths and high toxicity levels in these sensitive bottom dwelling animals that either made them unsellable or substantially reduced their populations for extended periods. And, in Crisfield, this devastation of ocean bottom dwelling life took a terrible and visible toll on human life there as well.


Why Context is So Important to Understanding Climate Change

In understanding the damage resulting from human caused climate change, context is everything. Because climate change is so large, we have to look at the big picture in order to understand it. All too often, we look at a long, thin, bushy, tufted thing, or a padded stump-like thing, or a spear-like protrusion of ivory and see only strange, isolated, and seeming in-congruent features. But when drawing back, what we find is an elephant.

And this is why I’m sharing with you my experience of the health of the waters surrounding the Chesapeake Bay, a set of waters I have had intimate contact with for most of my life, intimate enough to know that the life there is in severe crisis. So when scores of dolphins begin washing up dead on shores adjacent to the Chesapeake Bay and nearby ocean, one does not immediately jump to conclusions without investigating the larger context.

So, before we continue on a broader investigation, I’d like to call your attention once again to the satellite image at the top of this blog post and ask you to engage your senses. What do you see there? And does it look normal to you?

Morbillivirus or Failing Ocean Health?

Earlier this summer odd reports were emerging that Manatees were dying in unprecedented numbers along Florida waterways. Widespread red tides had expanded through Florida estuaries, coating the grasses Manatees consume in paralytic toxins. These toxins, when consumed in large enough amounts cause the Manatees muscles to seize up, making it impossible for the Manatees to reach the surface to breathe. From NPR as of March 28th:

More than 200 manatees have died in Florida’s waterways since January from an algae bloom called red tide, just as wildlife officials try to remove the marine mammal from the endangered species list.

In a separate incident during early June, reports had emerged that a large algae bloom was covering some East Coast beaches with an algal foam that is implicated in increasing ocean anoxia. From the Marine Institute as of May 27th:

The Marine Institute is currently monitoring an algal bloom on beaches on the east coast of Ireland as a part of its Phytoplankton Monitoring programme. The bloom was detected on May 27th  using satellite images and information provided by the Envirnomental Protection Agency and Wexford County Council.

The production of foam, and in some extreme cases anoxia, can result in marine organism mortalities. Fish mortalities caused by this particular species in previous Irish blooms have not been observed, as wild fish tend to avoid the bloom. This may explain the low catches reported by sea anglers on the east coast in recent weeks.  Several fishermen have also reported clogging of nets in recent weeks, which may be caused by the decaying bloom sinking to the seafloor.

In yet one more incident, an estuary of the Chesapeake Bay called the Lafayette River in Hampton Roads experienced yet one more dangerous red tide event. The Chesapeake Bay foundation reported the event which is under investigation by the Virginia Institute of Marine Science.

The findings match visual evidence of wide-spread algae blooms that can be seen from satellite in this region of the East Coast. And algae blooms can have numerous and devastating effects to marine ecosystems. The organisms involved in algae blooms often produce toxins which are directly dangerous to fish and marine wildlife. They starve the waters by consuming oxygen, at which point the oxygen consuming algae die and micro-organisms that thrive on anoxic conditions multiply. These organisms produce and use hydrogen sulfide as a means of cellular respiration increasingly as anoxic conditions expand. Hydrogen sulfide is a fat-soluble gas that is toxic to all forms of oxygen dependent life. It may become concentrated in both fish, mollusks and crabs. In high concentrations in mammals hydrogen sulfide is implicated in high fever, pneumonia like symptoms, multiple organ systems stress (including liver and kidneys), and is a potent neuro-toxin — attacking both nerve and brain function. LD 50 levels (the dose which is lethal for half the population) for most mammals are around 5 grams per kilogram. Direct inhalation of extraordinarily high levels of hydrogen sulfide acts similarly to cyanide gas and is almost immediately lethal.

Both anoxia and high hydrogen sulfide levels have been implicated in numerous fish kills occurring around the world as both oceans and inland waterways warm and become more favorable to large algae blooms. Such a change in ocean and water states has been implicated in numerous mass extinction events in the oceans and, in worst cases, on land (see The Deadly Climb From Glaciation to Hothouse, Why the Permian Extinction is Pertinent to Human Warming).

Finally, it is important to note that of the now 200+ dolphins that have washed ashore dead, only 3 have tested positive for morbillivirus.

As the above video shows, oceanographers and marine scientists at the Virginia Institute of Marine Science aren’t buying the morbillivirus explanation.

Perhaps the most stark evidence for a non-virus related death source, an indication of fat soluble toxins of the kind produced by large algae blooms, is the fact that those individuals most vulnerable to toxins are the ones that are seen to be dying at the most rapid rate. According to Smithsonian Institution scientist, Charlie Potter:

“Males don’t have a mechanism for shedding contaminants. The females shed significant amounts of their lipid-soluble contaminants through lactation, so the calf gets a hell of a dose early on in life, and some of the most outrageous levels of contaminants we’ve seen have been in calves.”

Susan Barco, also a scientist with the Smithsonian, noted that dolphins were a key indicator of ocean health and that when dolphins are dying in large numbers, something is seriously wrong:

“Bottlenose dolphins are a higher-order predator. They’re often referred to as ‘ocean sentinels of health.’ So when our bottlenose dolphins are healthy, it would probably indicate that we have a fairly healthy ecosystem. When our bottlenose dolphins are not healthy, it may very well indicate that our ecosystem is not healthy,” she said.


The ongoing loss of ocean health is, to me, a defilement of the very spirit of our world. As a child and teen, I was part ocean creature, with so much salt water in my veins. My first memories of her include my father joyfully tossing me into the, then crystalline, waves and then swimming in after me, taking me to the depths to cup small black fish in his hands as a gift of experience to my two-year-old self.

The moment of the black fish, swimming in my father’s hands, me staring at it, it looking back at me, so small, even compared to me, is still with me. I remember being afraid for the fish cupped in the large hands of my father. I remember thinking it might be hurt. Yet I also remember the wonder of the moment we shared, and the joy I felt as my father released it back to the waters.

I realize now that the life of the fish and my own life are connected and that they were never separate. The fish depends on me and my human fellows to act responsibly, to work to restore a now terribly sick world, to give it back the more healthy ocean of my childhood. And we, both you and I, depend on the fish to live, to do its good work in doing its own part to keep the oceans well, a safe place for humans and ocean dwellers alike. For together we become a part of a vibrant and self-reinforcing web of life. And, in breaking that web, we come to die alone and with great suffering.

I do not like this mass death of the dolphins whom we now know to call to each other across the oceans by name and with voices that carry through miles and miles of the still living, but greatly threatened, waters. And I am growing deeply tired of a great number of humans who obstinately fail to see the bigger picture, who continue to push for the delivery of ever greater harm and yet deny its growing force and violence. If the dolphins have names for one another, I wonder if they also have a name for such creatures that live among us?

    Revelation 11:18? The translation I use says “God will ruin those ruining the Earth.” This is the only scripture I am aware of that speaks about what we are experiencing pertaining to the destruction of the earth/environment. The fact that it comes in Revelation might be rather significant in thinking about how dire the situation would become.

    It is rather sad to see what is going on around us. The massive loss of bees and bats, the sad plight of the polar bears, the slaughter of rhinos and elephants, and the poisoning of dolphins and manatees just to name a few. 1John 5:19 tells us why, “The whole world is lying in the power of the wicked one.” It appears that Satan’s rule is about up.

    The world’s financial systems are in as bad of shape as our environment. The belief and trust in all governments has eroded to a point that I haven’t seen in my lifetime. The words of Abraham Lincoln come to mind, “A house divided against itself cannot stand.”

    • Revelation 11:18:

      “And the nations were enraged, and Your wrath came, and the time came for the dead to be judged, and the time to reward Your bond-servants the prophets and the saints and those who fear Your name, the small and the great, and to destroy those who destroy the earth.”

    homo interfector it has been my name for our species for these past years.

    your person expression here really touches me, it has been my connection to the sea through my life that was responsible for my first becoming concerned for the state of our world. the overwhelming sense that something was very wrong with all the death and disappearances i began seeing in my younger years. Like everywhere we now have massive algae blooms, anoxic zones, and die offs. the pacific north west where I have lived all my life has seen huge impacts from ocean acidification, and nutrient up-welling from changing ocean currents as well as temperature rise. people may scoff when I tell them this is not the ocean that I was born into, but it is the truth (with science to back me up). It leaves me with an unimaginable sadness, and yes it makes me extremely angry on many occasions. how can one put into words what the ocean is to our planet to our species, how can we express the horror and crime that is committed when we allow our species to destroy it, and ultimately ourselves, I do fear we are rapidly heading towards a canfield ocean state and I find that idea horrible beyond words…. you found some words to express what I feel and think. Thank you

    I lived in Florida for 12 years and spent a lot of time at the Gulf of Mexico. I used to race triathlons, so I swam a lot. I was crushed not just when the oil was dumped in massive quantities into the water, but the attitude of most of the people about it. People for the most part seemed concerned about what it would do to gas prices instead of what it was doing to the Gulf and the sea life in it. When the president quickly claimed that it was safe to eat food from the spill area, I knew that our government could no longer be trusted to look after our best interests.

    • There’s a strange kind of pressure not to care about the things that matter most. To only concern oneself with the day to day. I find it hard to understand.

      So what did that spill look like down there. Media give a good depiction?

      You still doing triathalons?

    Robert Oppenheimer is world famous for his use of the phrase “destroyer of worlds.”

    from wiki;

    We knew the world would not be the same. Few people laughed, few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the Prince that he should do his duty and to impress him takes on his multi-armed form and says, “Now I am become Death, the destroyer of worlds.” I suppose we all thought that, one way or another.

    Interview about the Trinity explosion, first broadcast as part of the television documentary The Decision to Drop the Bomb (1965), produced by Fred Freed, NBC White Paper; Oppenheimer is quoting from the 1944 Vivekananda – Isherwood translation of Bhagavad Gita. This is a line spoken by Krishna, who is revered in Hindu traditions as one
    of the major incarnations of Vishnu; some assert that the passage would be better translated “I am become Time, the destroyer of worlds.”

    • How could I miss the Gita reference?

      Thanks for including it.

      I find it somewhat ironic that the threat of a climate catastrophe — nuclear winter — was what got nations serious about reducing nuclear arsenals. Yet what we’re doing with fossil fuels and climate change is arguably far, far worse.

    What is happening to the dolphins is also happening to the Bangledeshies, Tuvaluans, & arctic Inuit.
    The mechanics are different, but the results are still suffering & early death.
    Every yuppie flying from Denver to Switzerland for skiing holidays is a murderer of dolphins & Bangledeshie children.
    We comfortable westerners with full bellies & full gas tanks are next on the reapers list.

    • Fossil fuel companies with their captive consumers. Millionaires and billionaires with multiple homes and cars who do not transition, though they have the capacity. Politicians, lobbying firms and advertising agencies that push a dangerous consumption and atmospheric dumping of fossil resources. Similar agencies and individuals who cover up the damage and blame the victim.

      The ones I’ve listed above are responsible for the devastation. The Yuppie on his once a year vacation to Switzerland? He’s just another one of their victims — pumped up on the illusion of a magical vacation and addicted to that fossil heroine we all, to one degree or another, have been forced to use.

      If you with to set the blame, put it squarely where it rests — on the pushers.

    A very brief but powerful video of the Hiroshima Holocaust.

    If the decent “normal” men in the B-29 could vaporize their fellow humans so cavalierly, including innocent women & children civilians; it is NOT a stretch to watch as we drown our fellows in Bangledesh first & then ourselves with our ingenious but selfish fossil fuel toys & games.

    Many of my well-educated staunchly environmentalist yuppie friends are still flying routinely for personal titillation.

    What a paradox to observe a world famous environmentalist, who preaches near term extinction of humans, flying from N. America to New Zealand to deliver a scholarly lecture on how industrialization & profligate burning of fossil fuels are clearly destroying our planetary habitat.

    “Most people have never known what was happening to them.”

    • If Bill McKibben succeeds in his mission to divest from fossil fuels and halt the use of unconventionals, then his use of air travel to rally supporters for this needed mitigation will be as a drop of water to an entire ocean of harm he’s helped remove.

      The difference between McKibben and the vacationer is as great as the difference between the vacationer and the wealthy oil exec/billionaire/climate change denier in Congress.

      Individual abolition of fossil fuels is helpful. But these problems are so large that they require concerted public and political action. Nothing short of working together on a large scale will have any chance of solving these problems. Some of us being responsible while others continue to loot and pillage will never, in the end, prove successful.

      I’m growing quite tired of this undermining those who are attempting to mount an effective response….

    I had already left Florida by then. I’m up in Illinois now. I still run, but I pretty much only bike on a stationary bike at the gym, so no more triathlons. Too many drivers texting, talking on cels, and just unwilling to share the road with bicyclists so the enjoyment of riding disappeared for me.

    About three years ago I was riding on a quiet scenic road and I had only encountered a couple cars over the course of about 10 miles. A white van missed my left elbow by a couple inches probably going 65-70 mph in a 45 zone. Don’t know if it was intentional or they never saw me for whatever reason. That pretty much had me pull the plug from riding on roads anymore.

    • Yeah, that’s just dangerous. Sorry to see it’s not safe for you anymore.

      I enjoyed running so much I gave myself a bone contusion and the doctor told me to take a six month break.

  11. Steve

     /  August 22, 2013

    Sorry to hear about your running setback. Hope you are able to find something you enjoy to takes its place for awhile.

  12. FYI, in case ya’ll missed the memo, it has been proven that navy sonar is causing marine mammals to go deaf. a deaf whale is a dead whale. it IS causing strandings.

    • These instances involve the washing up of already dead animals… In the case of sonar strandings, live animals with ruptured sensory organs are discovered. This pattern of death does not match that of a sonar stranding.

    Any known concerns about negative effects from shifts to our seasonal weather? If the forecast holds true, our hottest week of the summer here in Chicago will be taking place next week. What consequences might there be if we start seeing March being warmer than April and May or September being warmer than June/July? Our last 2 years of Dec/Jan weather have been much warmer than normal and with very little snowfall. I’m guessing there’s a price tag to these events that nature has to pay.

    • There is a huge list of consequences. What we are seeing is the slow and steady decline of both winter and seasonality as well. They won’t go quietly, though.

  16. During the flight we were able to get below the cloud layer of an approaching front, meaning that we could take a lot of low level readings over some of the target the Arctic wetlands in Northern Sweden and Finland, and whilst we didn’t see any methane enhancements indicative of high wetland emissions, we sampled a rather large amount of methane in an air mass that we believed to have come from north west Russia. Again, without full validation and calibration of the measurements it is difficult to say for certain, but the simultaneous enhancement of carbon monoxide and aerosol (both products of incomplete combustion processes) would seem to indicate the transport of a polluted air mass, with initial back-trajectory models also confirming this.

  17. UPDATE:

    New NOAA report finds 27 more dolphins with morbillivirus. Though NOAA’s not ruling out other causes, it’s starting to look like morbillivirus is a primary culprit this time.

    Are dolphins still dying in high numbers? I can’t find much that’s been written about this since the end of August.
