Hot river water curbs output at French #NuclearPlant
By Forrest Crellin
August 2, 2024PARIS, Aug 2 (Reuters) - "Electricity production at the #Golfech nuclear plant in southern #France was reduced by 1 gigawatt (GW) on Friday, EDF data showed, after the utility said high #WaterTemperatures on the #GaronneRiver could mean reduced output until Aug. 10.
"The restrictions are the first this year linked to high temperatures, which typically represent less than one percent of annual production.
"Nuclear output in France has been relatively consistent this year, following years of disruption caused by extended maintenance.
"EDF sometimes limits production when temperatures are near a threshold that varies depending on the nuclear plant.
On Thursday it extended a warning of possible reduced output that had been expected to end on Saturday.
EDF was not immediately available for comment.
LSEG data showed that the 28°C (82.4 Fahrenheit) temperature limit for the River Garonne that cools Golfech was breached once on July 31."Only one of several forecasts showed temperatures surpassing that level over the next week."
"'Dropping temperatures in France should ease the pressure and allow the plant to return to normal generation levels sooner. However, the beginning of next week has temperatures rising once again and problems could start once again,' LSEG analyst Ulrich Weber said."

#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."

"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."

Why isn't this sounding alarms?!! This is happening globally!
Harmful #algae detected in #OaklandCalifornia's #LakeMerritt could be 'an ominous sign for the Bay'
"Earlier this month, signs posted around Oakland’s Lake Merritt made some joggers stop in their tracks. 'Avoid water contact,' they cautioned in bold letters. 'Harmful algae may be present.'
"The warnings came after a mysterious red substance emerged in the water between the Lake Merritt Sailboat House and the Rotary Nature Center on March 7, as the Oaklandside first reported. Subsequent lab testing by the California Department of Public Health and #SanFranciscoBay Regional Water Quality Control Board last week confirmed the presence of Heterosigma akashiwo in the water — the same species of harmful algae responsible for the Bay Area-wide red tides and mass #FishKills reported in 2022 and 2023.
"But Eileen White, executive officer for the San Francisco Bay Regional Water Quality Control Board, told SFGATE on Tuesday that the current bloom has not reached those levels. 'The good news right now is the lake is looking good, and the red tide we originally observed has dissipated,' she said.
"White added that she runs around the lake just about every day, but did not observe any dead fish in the weeks since the algae was detected. The water has also returned to its usual color, she said.
"'But we’re still trying to understand what caused it. It was a little surprising, because we’ve had so much rain, and we typically associate these harmful blooms with warmer temperatures and less wind activity,' White said.
"'H. akashiwo has been documented across the world, but is most commonly found west of North America in #Japan, #NewZealand and #BritishColumbia, Canada. The species was first observed blooming in the central part of San Francisco Bay in July 2002, and was also spotted near Sausalito in 2004, depleting oxygen levels in the water and causing fish to asphyxiate en masse."

#GoldenAlgae toxin blooms to blame for fish kills at #Saguaro, #CanyonLakes
BY DAMON ALLRED
Mar 17, 2024PHOENIX — "Golden algae toxin blooms are behind recent #FishKills at Saguaro and Canyon lakes, the Arizona Game and Fish Department confirmed Friday.
"Golden algae, which can be harmful to gill-breathing animals such as fish, has affected Salt River chain lakes — Saguaro, Canyon and Apache — since 2003, the AZGFD said in a press release.
"Over the years, humans and other non-gill-breathing wildlife have not displayed negative health impacts after coming into contact with a golden algae toxin bloom.
"Hundreds of fish — mostly of the threadfin shad species — were observed to be dead or dying. Other species such as largemouth bass, bluegill and catfish were also affected."

Lough Neagh: Toxic algae potentially waking again
Louise Cullen - BBC NI agriculture and environment correspondent
March 7, 2024
"Toxic blue-green #algae in #LoughNeagh has potentially begun to wake up again already, with two confirmed reports since the start of 2024.
"Last summer, it brought the largest freshwater lake in these islands to the headlines.
"The algae also brought misery to those who live and work around and on the lough."

I'm seeing a pattern here...
"'On March 14, the Minnesota Department of Natural Resources responded to a fish die off on Traverse Lake in southwest #Minnesota near the city of Wheaton. DNR staff collected fish samples and checked dissolved oxygen in the water. The cause of the die off appears to be gas supersaturation trauma, also known as gas bubble disease, likely the result of an #AlgaeBloom in the lake,' a spokesperson for the Minnesota Department of Natural Resources told Newsweek in an email."
Thousands of Fish Found Dead as Ice Melts on Minnesota Border Lake
Published Mar 20, 2024
"Thousands of dead fish have been found in a Minnesota lake at the same time all its ice has melted.
"An estimated 2,000 to 3,000 fish were found dead in Lake Traverse, which lies along the border with #SouthDakota, on March 14, the West Central Tribune reported. They included freshwater drum, crappies, bluegills, white bass and bluegills. There was also a handful of smallmouth bass and walleye."

Thousands of #eels die mysteriously in #NewZealand
Story by Vishwam Sankaran
April 1, 2024"'We noticed some #algae build-up, which generally is due to the stream water warming up,' said Hona Edwards, a member of a local guardian group that monitors the stream.
"'Then the biggest percentage of the stream was observed to range from very limited to no water flow. When there’s no flow, the dissolved oxygen reduces, and the toxins build up in the waterway,' he said.
"Such algal blooms occur when conditions such as warm water temperatures and low water volumes are coupled with nutrient flows from agricultural use and toxic #pollutants from human activities.
"While mass deaths of freshwater fish are known to occasionally take place across the world, a study of lakes in #Minnesota and #Wisconsin in the United States found that such incidents have increased globally in the past decade."

#Gambierdiscus and Its Associated Toxins: A Minireview
The global spread of #CFP has led to Gambierdiscus and its toxins being considered an environmental and human health concern worldwide.
Da-Zhi Wang, et al.
July, 2022"Gambierdiscus is a dinoflagellate genus widely distributed throughout tropical and subtropical regions. Some members of this genus can produce a group of potent polycyclic polyether #neurotoxins responsible for #ciguatera fish poisoning (CFP), one of the most significant food-borne illnesses associated with fish consumption. Ciguatoxins and #maitotoxins, the two major toxins produced by Gambierdiscus, act on voltage-gated channels and TRPA1 receptors, consequently leading to poisoning and even death in both humans and animals. Over the past few decades, the occurrence and geographic distribution of CFP have undergone a significant expansion due to intensive #anthropogenic activities and global #ClimateChange, which results in more human illness, a greater public health impact, and larger economic losses. The global spread of CFP has led to Gambierdiscus and its toxins being considered an environmental and human health concern worldwide."

WHOI: Harmful Algae: #Gambierdiscus
- Benthic dinoflagellate genus
- Over 18 defined species and several ribotypes identified
- Found globally in tropical and subtropical regions
- Produce #ciguatoxins, which may lead to:
• Human illness (Ciguatera Poisoning)
• Significant public health impacts
• Economic losses associated with health-related costs and lost productivity"Taxonomic studies have identified at least 18 species within the Gambierdiscus genus, many of which co-occur and differ significantly in toxicity. At least ten of these species have been found in tropical and subtropical regions of the U.S., including #Hawaii, the #GulfOfMexico, the #FloridaKeys, #PuertoRico, and the #USVirginIslands.
"Temperature is a key factor controlling CTX occurrence, and laboratory experiments investigating the influence of temperature on growth of various Gambierdiscus species have shown that most species exhibit maximum growth rates between 24–30°C, but that growth responses varied by species. For example, temperature tolerances vary among species, although all are sensitive to higher temperatures, with steep declines in growth as temperatures exceed ~31°C.
"Thus higher temperatures may favor growth of more thermally tolerant species in ciguatera endemic regions, and promote establishment of species shown to be less tolerant in subtropical and temperate regions. Warm surface temperatures may also favor increased abundance of Gambierdiscus populations in deeper waters.
"There is recent evidence of geographic range expansion of #Gambierdiscus and CP into higher latitudes in U.S. waters, associated with climate-driven warming. Over the past two decades CP and CTXs were reported for the first time in the northern Gulf of Mexico, and ephemeral populations of Gambierdiscus have also been documented in #NorthCarolina. Prolonged periods of elevated water temperatures at these locations and in northern Florida are hypothesized to result in increased Gambierdiscus and Fukuyoa cell densities."

Harmful algal blooms and climate change: Learning from the past and present to forecast the future
Mark L. Wells, et al.
Sept 22, 2015Abstract:
"Climate change pressures will influence marine planktonic systems globally, and it is conceivable that harmful algal blooms may increase in frequency and severity. These pressures will be manifest as alterations in temperature, stratification, light, ocean acidification, precipitation-induced nutrient inputs, and grazing, but absence of fundamental knowledge of the mechanisms driving harmful algal blooms frustrates most hope of forecasting their future prevalence. Summarized here is the consensus of a recent workshop held to address what currently is known and not known about the environmental conditions that favor initiation and maintenance of harmful algal blooms. There is expectation that harmful algal bloom (HAB) geographical domains should expand in some cases, as will seasonal windows of opportunity for harmful algal blooms at higher latitudes. Nonetheless there is only basic information to speculate upon which regions or habitats HAB species may be the most resilient or susceptible. Moreover, current research strategies are not well suited to inform these fundamental linkages. There is a critical absence of tenable hypotheses for how climate pressures mechanistically affect HAB species, and the lack of uniform experimental protocols limits the quantitative cross-investigation comparisons essential to advancement. A HAB “best practices” manual would help foster more uniform research strategies and protocols, and selection of a small target list of model HAB species or isolates for study would greatly promote the accumulation of knowledge. Despite the need to focus on keystone species, more studies need to address strain variability within species, their responses under multifactorial conditions, and the retrospective analyses of long-term plankton and cyst core data; research topics that are departures from the norm. Examples of some fundamental unknowns include how larger and more frequent extreme weather events may break down natural biogeographic barriers, how stratification may enhance or diminish HAB events, how trace nutrients (metals, vitamins) influence cell toxicity, and how grazing pressures may leverage, or mitigate HAB development. There is an absence of high quality time-series data in most regions currently experiencing HAB outbreaks, and little if any data from regions expected to develop HAB events in the future. A subset of observer sites is recommended to help develop stronger linkages among global, national, and regional climate change and HAB observation programs, providing fundamental datasets for investigating global changes in the prevalence of harmful algal blooms. Forecasting changes in HAB patterns over the next few decades will depend critically upon considering harmful algal blooms within the competitive context of plankton communities, and linking these insights to ecosystem, oceanographic and climate models. From a broader perspective, the nexus of HAB science and the social sciences of harmful algal blooms is inadequate and prevents quantitative assessment of impacts of future HAB changes on human well-being. These and other fundamental changes in HAB research will be necessary if HAB science is to obtain compelling evidence that climate change has caused alterations in HAB distributions, prevalence or character, and to develop the theoretical, experimental, and empirical evidence explaining the mechanisms underpinning these ecological shifts."Mention of Gembierdiscus:
"#Gambierdiscus toxicus is known to generally favor warmer conditions, and increased ciguatera fish poisoning has been observed with elevated sea surface temperatures related to El Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) (Rongo and van Woesik, 2011). But this linkage is correlative, rather than determined, and temperature optima differ substantially among different Gambierdiscus species or phylotypes (Yoshimatsu et al., 2014). The cell-size dependent population response to warming also differs among phytoplankton groups. Specifically, picophytoplankton biomass appears to increase with temperature, unlike non-cyanobacterial communities which tend to respond in the opposite (Karlberg and Wulff, 2013; Morán et al., 2010). Despite this, unusual blooms of both may be linked to climatic events (Gómez and Souissi, 2007)."

In Florida Keys, researchers investigate fish 'spinning and whirling' before dying
March 29, 2024
by Ehren Wynder
"A likely suspect is a naturally occurring toxin produced by an algae called #Gambierdiscus. Researchers detected elevated levels of it in areas with affected fish, as well as in the gut contents of some affected fish."The toxin is commonly found to accumulate on fish in #CoralReefs where the algae is found, It is not typically dangerous to the fish, but can be dangerous and even lethal to humans.
"Parsons said its presence was 'anywhere from five times higher to about 30 times above averages we've seen over the past 10 years.'
"'The maximum numbers we saw were below 10,000 cells per liter of water,' he said. 'That (number) is a lot for Gambierdiscus, but it's not a lot in terms of our typical blooming species. So that's one reason why Gambierdiscus was kind of under the radar here.'
"The link between Gambierdiscus and the spinning fish has not yet been proven, but scientists are chasing it as their strongest lead.
"The BTT and FWC recommend people avoid eating fish harvested from areas where affected fish have been observed and to avoid swimming in areas with dead and symptomatic fish."
