“As humans continue to pollute these environments with nutrients from wastewater treatment plants, urban, industrial and agricultural runoff, and as we continue to change and warm the climate, we will see more of these events; so monitoring and expanded research is needed.”

Fossil fuels, Marine heatwaves and Runoff: The bloom pulsates
"Algal blooms are complex, but the prevailing theory is that the 2022-23 floods washed nutrients down the Murray-Darling Basin system and out to sea. A marine heatwave and an “upwelling” of nutrients from the bottom of the ocean combined to create the perfect conditions for Karenia mikimotoi to flourish."

#Wildfires, including the #EatonFire & #PalisadesFire, have significant repercussions on #marine #ecosystems. The ash & debris from these fires can enter waterways & eventually the #ocean, altering nutrient levels & fostering conditions favorable to the growth of harmful #AlgalBlooms. The #toxic byproducts from these fires can exacerbate #OceanWarming, further promoting the frequency of these toxic blooms. This can lead to increased production of #DomoicAcid.

#DomoicAcid is a potent neurotoxin produced by certain phytoplankton species, which are significant contributors to harmful #AlgalBlooms. These toxins accumulate in the tissues of #MarineMammals & other #wildlife consuming contaminated prey. Recent changes in #ocean conditions,…intensified by #environmental factors such as the #EatonFire & #PalisadesFire, have accelerated the proliferation of these harmful algal blooms.

#Sewage dumped illegally in #Windermere over 3 years
by Joe Crowley
October 17, 2024"A water company repeatedly dumped millions of litres of raw sewage illegally into one of #ngland's most famous lakes over a three-year period, the BBC can reveal.
"More than 140 million litres of waste were pumped into Windermere between 2021 and 2023 at times when it was not permitted, our analysis shows, and #UnitedUtilities failed to report most of it.
"It means the company's #IllegalDumping of #sewage into the lake went on for far longer, and was far more extensive, than was previously known.
"United Utilities said some of its sewage releases into #Windermere were 'potentially non-compliant' but that it #SelfReports 'over 94% of potential pollution incidents to the #EnvironmentAgency'.
"Matt Staniek, a campaigner against sewage pollution and founder of #SaveWindermere, said Windermere was 'the jewel in the crown of the #LakeDistrict #NationalPark, and it's being used as an open sewer'.
"It is sometimes necessary to release sewage into rivers and lakes to stop the wastewater system from being overwhelmed by #HeavyRain but this #pollution can damage the environment, causing harmful #AlgalBlooms and even killing fish.
"In January this year - after BBC Panorama revealed the company had downplayed the severity of dozens of #pollution incidents, some involving Windermere - United Utilities retrospectively reported some discharges into the lake from October 2023 onwards."

Sinking in Saltwater: #Maine’s #coastal #marshes at risk as sea levels rise
Between 28 and 57 percent of the state’s coastal marshes could disappear by the end of the century, victims of a rising sea, coastal #development and #PollutedRunoff.
By
Kate Cough
July 28, 2024PORTLAND — "It takes hundreds of years for a #SaltMarsh to form, for fine sediment brought in on the tides to settle in sections of shoreline sheltered from the worst of the wind and waves. As salt-tolerant plants — smooth #cordgrass, #SaltmarshHay, #saltgrass, #BlackRush — begin to grow, their dense stems and roots trap more sediment, and the marsh builds more rapidly, up and out.
"#Crabs, #shrimp and #worms arrive, drawn to the rich food of dying marsh grasses, followed by a variety of #fish — #alewives, #StripedBass, #smelt and Sea-run #BrookTrout among them — many of which eventually migrate between the marsh and the sea.
logo for the sinking in saltwater series"Acre by acre, a healthy salt marsh anchors a #FoodWeb 'more productive than most midwestern #farmland,' according to a 2003 paper published by the University of Maine.
"The same dense grasses that are so good at trapping silt also excel at ensnaring pollutants, pulling out nitrogen and nutrients that cause #AlgalBlooms, and burying #toxic #contaminants in the peat.
"Once established, plants in salt marshes grow quickly, fed by the rich soil, and pull #carbon from the atmosphere. Salt marshes are ten times more effective at storing carbon than tropical forests, and, left undisturbed, can trap the gas in the ground for centuries, a phenomenon scientists refer to as 'blue carbon.'
"Maine has some of the most extensive blue carbon reservoirs in the northeast — second only to Massachusetts, according to a study published by the Environmental Protection Agency in 2023.
"But as sea levels rise and development presses in, these reservoirs, and the habitats they create, are at risk of disappearing.
"An analysis by the University of Maine suggests that a significant portion of the Maine’s salt marshes — between 28 and 57 percent, depending on the sea level rise scenario — could be gone by the end of the century. They are also threatened by polluted runoff from #pesticides, #septic systems and #AgriculturalWaste.
"'The decisions Mainers make over the next 10 years are going to determine whether these important ecosystems persist,' said Bates professor Beverly Johnson, who has been studying blue carbon for years, speaking to The #MaineClimateCouncil in December.
"Over the past 25 years, nearly 300 acres of Maine’s wetlands — both fresh and saltwater — have been impacted by or lost to development, according to a Press Herald/Maine Monitor analysis of data from the state’s In Lieu Fee Compensation Program. The program allows developers to fill or convert certain #wetlands if they pay a fee, money that is used for conservation projects elsewhere."

"But as sea levels rise and development presses in, these reservoirs, and the habitats they create, are at risk of disappearing.
"An analysis by the University of Maine suggests that a significant portion of the Maine’s salt marshes — between 28 and 57 percent, depending on the sea level rise scenario — could be gone by the end of the century. They are also threatened by polluted runoff from #pesticides, #septic systems and #AgriculturalWaste.
"'The decisions Mainers make over the next 10 years are going to determine whether these important ecosystems persist,' said Bates professor Beverly Johnson, who has been studying blue carbon for years, speaking to The #MaineClimateCouncil in December.
"Over the past 25 years, nearly 300 acres of Maine’s wetlands — both fresh and saltwater — have been impacted by or lost to development, according to a Press Herald/Maine Monitor analysis of data from the state’s In Lieu Fee Compensation Program. The program allows developers to fill or convert certain #wetlands if they pay a fee, money that is used for conservation projects elsewhere."

#ClimateChange Contributes to Shift in #LakeErie’s Harmful #AlgalBlooms
Blooms over the past decade have started earlier in July and had longer peaks, according to #NOAA researchers.
By Kathiann M. Kowalski
July 26, 2024"Lake Erie’s harmful algal blooms have started sooner and had longer peak periods over the past decade compared to earlier years, newly released data shows. Warming temperatures linked to climate change are a cause, according to researchers for NOAA’s National Centers for Coastal Ocean Science, with interactions among species likely playing a role as well.
"The NOAA scientists discussed the shift and forecast a moderate to above-moderate algal bloom for the lake’s western basin this summer during a briefing last month at Ohio State University and Ohio Sea Grant’s Stone Laboratory, off the coast of Put-in-Bay on Lake Erie.
"Algal blooms occur when #cyanobacteria, or blue-green algae, grow out of control due to a combination of excess #nutrients, #weather patterns and other #ecological factors. The blooms can be a serious public health problem because some types of cyanobacteria produce toxins. #Microcystin, for example, can lead to skin rashes, gut problems and liver and kidney issues. Relatively high levels of it in August 2014 prompted a two-day shutdown of #Toledo’s public #WaterSupply, which comes from Lake Erie."

Algal Toxins and Wildlife Health
By National Wildlife Health Center September 30, 2019
"Harmful #AlgalBlooms (#HABs) have the potential to harm fish and wildlife, domestic animals, livestock, and humans through toxin production or ecological disturbances such as oxygen depletion and blockage of sunlight.
"To investigate the effects of algal toxins on wildlife, the USGS National Wildlife Health Center (NWHC) has examined over 300 dead animals collected during freshwater and marine #HAB events since 2000. Varying levels of algal toxins were found in over 100 of these animals. In some cases, the history, clinical signs, and high toxin levels have allowed scientists to attribute mortality to algal toxicosis. Recent events have included Kittlitz’s #murrelets (Brachyramphus brevirostris) in Alaska that died after consuming sand lance (Ammodytes hexapterus) high in #saxitoxin (Shearn-Bochsler et al. 2014), #GreenTreeFrogs (Hyla cinerea) in Texas with suspected #brevetoxicosis in association with a #RedTide event (Buttke et al. 2018), and #LittleBrownBats (Myotis lucifugus carissima) in Utah found dead during a HAB event at a reservoir commonly used for recreation and as a source of municipal #DrinkingWater (Isidoro-Ayza et al. 2019).
"In other cases, algal toxins have been detected in wildlife, but their contribution to mortality remains unclear. Part of the reason these detections have been difficult to interpret is that the toxic dose of many algal toxins in wildlife species is unknown and the microscopic lesions (if any) particularly in birds, have not been well described. To better understand the effects of these toxins the NWHC is conducting laboratory exposure trials to determine the lethal dose of toxin in birds and to examine the repeated exposure of waterfowl to sub-lethal toxin ingestion. In addition to exposure trials, NWHC is undergoing a retrospective review of previous detections of algal toxin from NWHC’s case archives to examine demographic, spatiotemporal, and diagnostic features associated with wildlife exposure to algal toxins."

Fresh water is “rushing like a firehose out of the delta” into the Bay says Baykeeper scientist @jarosenfield, and that’s helping to repress fish-killing #algalblooms--for now.
But we will need MAJOR wastewater upgrades to prevent red tides like the one we experienced last summer! https://sfchronicle.com/climate/article/san-francisco-bay-water-17923903.php #harmfulalgae #harmfulalgaeblooms #redtide #cawater #californiawater
