30 Whales Have Died Off the Coast of Alaska and No One Knows Why
Whales are dying off the coast of Alaska and no one knows why. Yesterday, the National Oceanic and Atmospheric Administration (NOAA) officially declared the recent deaths of 30 large whales in the western Gulf of Alaska an "unusual mortality event," triggering an investigation into the cause of the mass die off. NOAA defines an unusual mortality event as "a stranding event that is unexpected, involves a significant die-off of a marine mammal population, and demands immediate response."

Since May, 11 fin whales, 14 humpback whales, one gray whale and four unidentified cetaceans have stranded around the islands of the western Gulf of Alaska and the southern shoreline of the Alaska Peninsula. The uptick is nearly three times the average for the area. Last year, there were only five whale strandings for the entire year. There were also six dead stranded whales reported along British Columbia's north coast in the last few months, which is a significant increase above annual seasonal numbers for that area as well.
"NOAA Fisheries scientists and partners are very concerned about the large number of whales stranding in the western Gulf of Alaska in recent months," said Dr. Teri Rowles, NOAA Fisheries' marine mammal health and stranding response coordinator. "While we do not yet know the cause of these strandings, our investigations will give us important information on the health of whales and the ecosystems where they live."
NOAA is encouraging the public to help out by immediately reporting any sightings of dead whales or distressed live animals they discover, but warns people not to get close or touch the animals.
"The prevailing theory is that a large toxic algae bloom off the West Coast might be to blame," reports CBC News. "However, scientists have been unable to make a concrete connection."
The West Coast has experienced the largest toxic algae bloom in a decade, forcing the closure of fisheries from California to Washington. This isn't the first time scientists have linked algae blooms and whale die offs. A toxic algae bloom this spring off the coast of Chile is the suspected cause of death for 20-30 sei whales.
"When algae that produces toxins overtakes a body of water, those toxins make it into the food chain by way of the tiny creatures that feed on it," reports the Washington Post. "In the case of these sei whales, the scientists studying them hypothesize, sardines poisoned by the algae could have given the whales deadly food poisoning."
NOAA cautions that these investigations often take months, even years, of data collection and analysis to reach a conclusive answer. So far, scientists working in Alaska have only been able to take the tissue sample of one of the carcasses, which NOAA described as a "less than ideal" sample. That sample tested negative for a type of toxin produced by algae, but the carcass was so decomposed that it may not be reliable, The Alaska Dispatch News reported. The scientists did not find a clear cause of death from that sample and many of the other carcasses have been unretrievable, or too badly decomposed to study.
"Alaska has an awful lot of coastline and much of it is difficult to reach," NOAA adviser Dr. Bree Witteveen told CBC News. "We can't get to those carcasses more often than not." They also have to deal with "predator competition" for sample sizes from the likes of bears and other animals.
NOAA said in an online FAQ that it's "highly unlikely" that radiation from Fukushima is playing a role, but "further testing is under way." Some have speculated that warmer temperatures may be to blame. The Alaska Dispatch News reported in June that surface temperatures in the Gulf of Alaska were running 0.9 to 3.6 degrees above average. There is no doubt that Alaska is rapidly warming due to climate change. Alaska's glaciers are melting even faster than most places along with the rest of the Arctic, which is warming at twice the rate of other regions.

Tropical Storm Josephine Also No Threat to Land<p>Meanwhile, the season's record-earliest tenth named storm, Tropical Storm Josephine, was also struggling with high wind shear as it traced out a path over the open ocean.</p><p>At 5 a.m. EDT Saturday, Josephine was located about 310 miles east of the northern Leeward Islands, moving west-northwest at 15 mph with top sustained winds at 45 mph. Josephine is expected to bring one to three inches of rain over portions of the northern Leeward Islands, the Virgin Islands, and Puerto Rico over the weekend. Josephine will encounter steadily rising wind shear through Monday, peaking at a very high 30 – 35 knots. This high shear is likely to destroy Josephine's circulation by Monday, before the storm can affect any other land areas.</p><p><em>Reposted with permission from <a href="https://yaleclimateconnections.org/2020/08/tropical-storm-kyle-forms-unlikely-to-affect-land/" target="_blank">Yale Climate Connections</a>. </em><em></em></p>

In May 2017, shells started washing up along the Ligurian coast in Italy. They were small and purple and belonged to a snail called Janthina pallida that is rarely seen on land. But the snails kept coming — so many that entire stretches of the beach turned pastel.
The Ligurian coast has been swept by snails turning its color pastel.
A World Between Worlds<p>The neuston comprises a multitude of weird and wonderful creatures. </p><p>Many, like the Portuguese man-of-war, which paralyzes its prey with venomous tentacles up to 30 meters long, are colored an electric shade of blue, possibly to protect themselves against the sun's UV rays, or as camouflages against predators.</p><p>There are also by-the-wind sailors, flattish creatures that raise chitin shields from the water like sails; slugs known as sea dragons that cling to the water's surface from below with webbed appendages; barnacles that build bubble rafts as big as dinner plates; and the world's only marine insects, a relation of the pond skater.</p><p>They live "between the worlds" of the sea and sky, as Federico Betti, a marine biologist at the University of Genoa, puts it. From below, predators lurk. From above, the sun burns. Winds and waves toss them about. Depending on the weather, their environment may be warm or cool, salty or less so.</p>
Sea snails can make up the neuston.
Velella velella jellyfish living on the surface of the ocean.<p>But now, they face another — manmade — threat from nets designed to catch trash. A project called <a href="https://theoceancleanup.com/" target="_blank">The Ocean Cleanup</a>, run by Dutch inventor Boyan Slat, has raised millions of dollars in donations and sponsorship to deploy long barriers with nets that will drift across the ocean in open loops to sweep up floating garbage. </p>
Collecting With the Current<p>"Plastic could outweigh fish in the oceans by 2050. To us, that future is unacceptable," <a href="https://www.dw.com/en/green-entrepreneur-sets-sights-on-great-pacific-garbage-patch/a-38855785" target="_blank">The Ocean Cleanup</a> declares on its website.</p><p>But Rebecca Helm, a marine biologist at the University of North Carolina, and one of the few scientists to study this ecosystem, fears that The Ocean Cleanup's proposal to remove 90% of the plastic trash from the water could also virtually wipe out the neuston.</p><p>One focus of Helm's studies is where these organisms congregate. "There are places that are very, very concentrated and areas of little concentration, and we're trying to figure out why," says Helm.</p><p>One factor is that the neuston floats with ocean currents, and Helm worries that it might collect in the exact same spots as marine plastic pollution. "Our initial data show that regions with high concentrations of plastic are also regions with high concentrations of life."</p>
Waste collection in the Pacific Ocean heralded by The Ocean Cleanup.<p>The Ocean Cleanup says Helm's concerns are based on "misguided assumptions."</p><p>"It's true that neustonic organisms will be trapped in the barriers," says Gerhard Herndl, professor of Aquatic Biology at the University of Vienna and one of project's scientific advisors. "But these organisms have dangerous lives. They're adapted to high losses because they get washed ashore in storms and they have high reproductive rates. If they didn't, they'd already be extinct."</p><p>Helm says they just don't know how quickly these creatures reproduce, and in any case recovering from passing storm is very different from surviving The Ocean Clean Up's systems which could be in place for years.</p>
Communication Breakdown<p>The Ocean Cleanup invited Helm to a symposium on the topic in December, where both sides presented their points of views and didn't seem to find much common ground. Since then, direct communication between them has stopped, says Helm. "They're not interested in talking to me anymore."</p><p>Both sides agree that much is still unknown about the neuston. But one thing that has been established is that most of the oceans' fish spend part of their lifecycle in the neuston. "More than 90% of marine fish species produce floating eggs that persist on the surface until hatching," Betti says.</p><p>The Ocean Cleanup has undertaken one of the few studies into this ecosystem, collecting data on the neuston on the relative abundance of neuston and floating plastic debris in the eastern North Pacific Ocean during a 2019 expedition to the Pacific Garbage Patch, an area where plastic pollution has accumulated on a vast scale. But it is not yet sharing what it has found. The information was being prepared for publication in an as of yet unspecified journal, probably some time next year, an Ocean Cleanup spokesperson said. </p>
Inshore Solution?<p>Helm believes the best way to tackle the marine plastic problem would be to position the barriers closer to land — across river mouths and bays — to catch garbage before it reaches the sea.</p><p>"Stopping the flow of plastic into the ocean is the most cost-effective — and literally effective — way to ensure that it's not entering our environment," she says. </p><p>As for the plastic already floating in open waters, she does not believe it is worth sacrificing parts of neuston and wants to see more research first. </p><p>The Ocean Cleanup has made barriers across rivers a part of its mission. But it is also going ahead with its original vision of pulling trash from the open water. In late 2018, the project deployed a 600-meter, u-shaped prototype net into the <a href="https://www.dw.com/en/environment-conservation-plastic-oceans/a-54436603" target="_blank">Great Pacific Garbage Patch</a>. </p><p>The system ran into difficulties, failing to retain plastic as hoped, and needing to be brought shore for repairs and a design upgrade, after which Ocean Cleanup says it gathered haul of plastic that it will recycle and resell to help fund future operations.</p><p>Over the next two years, the project hopes to deploy up to 60 such barriers to collect drifting flotsam. Helm isn't the only one concerned about these plans.</p><p><span></span>"We should think twice about every action we take in the sea," Betti says. "In nature, nothing is as easy as we think, and often, we've done a lot of damage while trying to do a good thing."</p><p><em>Reposted with permission from <a href="https://www.dw.com/en/environment-conservation-plastic-oceans/a-54436603" target="_blank">Deutsche Welle</a>.<a href="https://www.ecowatch.com/r/entryeditor/2646992655#/" target="_self"></a></em><em></em></p>
