What can you do if a #lake is in a bad state?
Especially in #summer ☀️ when it’s #hot 🌡️, lakes seem to lose their balance: murky #water, foul odours, #algal blooms, fish deaths, lack of or overgrowth of #aquatic plants, and falling water levels. Our new IGB Manual: https://www.igb-berlin.de/en/news/new-guide-what-do-when-lake-poor-health -
#Algal #Toxins emerge as a new concern in #Alaska’s Northern Bering Sea
Locals who depend on the sea for food and culture are trying to understand the risks to traditional foods and wildlife populations in a region undergoing myriad changes
by Yereth Rosen, Alaska Beacon, May 31, 2026 via #ICTNews
Excerpt: "For countless generations, people of the #BeringStrait region have relied on the food they harvest from the sea without worrying about #HarmfulAlgalBlooms [#HABs] that threaten seafood eaters in warmer and more southern latitudes.
"Now, as the Northern Bering Sea undergoes cascading effects of a warming climate, algal risks pose a new challenge.
"The change has been dramatic.
"And it has prompted a change in the way #Nome youth grow up learning about collecting food from the waters around their home. In early April, Nome high school students traveled to Bethel with their science teacher, where they presented their research at the Western Alaska Interdisciplinary Science Conference held by Alaska Sea Grant.
"Algal toxins were present, at very low but detectable levels, in fish they eat.
"Sophomore Audrey Bruner-Alvanna was among the group of student researchers. She said young people are concerned about algal blooms, which proliferate in warmer conditions, and their potential effects on wild food resources.
" 'Because, you know, as the climate changes, as the world gets warmer and stuff, there’s going to be more of these toxins and stuff during summer,' she said. 'I feel like a lot of people that I’ve talked to have been wondering about how our subsistence is going to change in the future based on all of that.'
"The student research came about after one of the nation’s densest and biggest concentrations of toxin-producing Alexandrium algae ever documented burst forth in the waters of the Bering Strait region in 2022.
"Until the appearance of the 'massive bloom, the most toxic bloom, the longest-persisting bloom in the U.S.,' local people barely knew what harmful algal blooms or #Alexandrium are, said Emma Pate, president of the Nome Eskimo Community, the local tribal government.
" 'So we had to figure things out and learn really fast,' Pate said during an October 'Strait Science' presentation hosted by the University of Alaska Fairbanks’ Nome campus."

Elevated nutrient runoff, #freshwater discharges, and harmful #algal blooms are accelerating coastal acidification in Florida's Indian River Lagoon, resulting in critically low levels of #aragonite saturation necessary for shell-building organisms to survive.

The #algal blooms increasingly seen in Canadian lakes have been linked to both nutrient #pollution from #agricultural runoff and #climate change. However, a new Concordia-led study using #DNA sequencing of lakebed #microbes reveals that these two drivers amplify each other in ways that profoundly affect the health of lake #ecosystems.

"What is causing this?
Things to know about FDA warning on paralytic shellfish poisoning in Pacific Northwestby CLAIRE RUSH
Updated 5:29 PM EDT, June 10, 2024"A 'very large' #algal bloom has resulted in “unprecedented levels” of PSP toxins along Oregon’s coast, Matthew Hunter, shellfish program manager for the Oregon Department of Fish and Wildlife, said during a briefing.
"The toxins have accumulated in the shellfish, sickening some people who have eaten them.
"While the factors that create harmful algal blooms are not well understood, certain factors — resulting from both natural processes and human activities — are believed to play a role, according to the National Oceanic and Atmospheric Administration.
“'Studies show that many algal species flourish when wind and water currents are favorable,' the agency says on a webpage dedicated to explaining harmful algal blooms. Some blooms, it says, stem from 'sluggish water circulation, unusually high #WaterTemperatures, and #ExtremeWeather events like #hurricanes, #floods, and #drought.'
"Algae growth can also increase when nutrients used in #fertilizers, mainly phosphorus and nitrogen, flow into bodies of water, according to the agency."

#PhotoOfTheDay: Ethereal #Algal vortex blooms at the heart of massive Baltic 'dead zone'
In 2018, satellite images captured a stunning spiral of #Cyanobacteria blooming in the Baltic Sea.
The swirling mass of microbes helped to create a massive "dead zone" the size of West Virginia that starved the surrounding water of oxygen.

California toxic algal bloom kills or sickens hundreds of dolphins and sea lions
Hundreds of #sea #lions and #dolphins are sprawled across the beaches in Southern California, either dead or sick and exhibiting abnormal behavior.
Officials have received more than 1,000 calls in recent weeks from beachgoers, tourists and residents reporting sick, dying and dead sea mammals washed ashore from #SantaBarbara to #SanDiego County, amid a growing #toxic #algal #bloom in the waters off the coast.
The wave of dead or sick animals is “one of the largest in memory,” Justin Greenman, a stranding coordinator with NOAA Fisheries, told CNN. “It’s completely overwhelming.”

Earth’s Largest #Extinction Event Saw Toxic Algal Blooms at #CO2 Concentrations Observed Today
On September 15, researchers published a study finding that the smoke and ash from #Australia's devastating 2019 and 2020 #wildfires had likely triggered a widespread #algal bloom in the Southern Ocean.
Two days later, another study published in Nature Communications revealed that this sort of thing had happened before. In the #Permian...
