Checking out the #algalbloom in southern #Adelaide. The incoming tide at the Onkaparinga river mouth looks deceptively clean this evening 👍
Interesting that while we’re busy researching alternatives for mitigating South Australia’s coastal algal bloom, nature is doing its own thing. A significant amount of clay has washed down from the Port Willunga cliffs into the ocean. Result: very few dead marine creatures on the beach this afternoon.

@anne_twain FFS! Nuclear plant discharges of heated water can also increase #HABs! Very bad!
" 'It is possible that activities associated with the working [desalination] plant, such as brine discharge and entrainment in the intake structure, will change the ecology of the plankton in the region and may promote blooms of harmful/toxic algal species which have been identified as components of the plankton community off Port Stanvac. Further monitoring is required before the impact of the Adelaide desalination plant on the plankton community off Port Stanvac can be adequately assessed.' "

Why the #GulfOfMaine Surface Ocean Waters are Warming Faster than Elsewhere
Posted on July 23, 2024Written by Rob Moir, Ph.D. No Comments
"None of us are strangers to the reports of the Gulf of Maine heating 97% faster than the world’s oceans. However, the actual reasons for this can be lost in the constant headlines about global warming and rising greenhouse gases. To explain this extraordinary phenomenon, let’s look closely at four factors: surface seawater temperatures, heat severity, air temperature, and rainfall, monthly for five years."

So, the waters off the Maine coast have been warming up (it was very warm when I last waded in the waters in May). Seems
Karenia mikimotoi has appeared here as well. I expect to see it return with warming waters... Also, this article claims it's less toxic that Red Tide (a cousin) -- but from what I just read in the ABC News article, I would disagree with that! @anne_twain @Tooden
From WHOI:
"Karenia mikimotoi
- Globally distributed, can cause mass die-offs of shellfish, crustaceans, echinoderms and fish
- Karenia mikimotoi produces several toxic compounds, blooms can also lead to anoxic conditions
- First bloom in Maine occurred in 2017, with a second bloom in 2019
- Karenia mikimotoi is also found in Massachusetts waters
"What is Karenia mikimotoi?
"In recent years, the genus Karenia has made the news in the United States as a result of the massive #RedTides caused by #KareniaBrevis [That's the one I know about]. These blooms have caused widespread fish and wildlife mortalities and impacted public health in Florida leading to significantly disrupted tourism and fisheries industries which have cost local economies millions of dollars in damages on an almost annual basis.
"Compared to this notorious HAB species, its sister species, Karenia mikimotoi, is less toxic [!!! Ummmm....] but more globally widespread with blooms reported in Ireland, Norway, India, Japan, Korea Australia, South Africa, Alaska, Texas, and the east coast of the U.S. The blooms of this species can stretch many kilometers, persist for multiple months, and reach concentrations of several million algal cells per liter.
"There have not been confirmed reports of direct impacts to human health by #KareniaMikimotoi, but blooms of this species can cause large-scale mortality events of marine fauna such as shellfish, echinoderms, crustaceans, and fish. Karenia mikimotoi has been shown to produce several toxic compounds as well as reactive oxygen species, but toxicity is highly variable by strain and the factors contributing to mortality events are still not entirely understood. Although overall concentrations of toxins in K. mikimotoi appear to be relatively low, there is evidence that their effect may be enhanced when the cells come into direct contact with fish gills. Anoxic conditions can also occur when K. mikimotoi cells die in large numbers and subsequent breakdown by bacteria deplete oxygen in the surrounding waters. These anoxic events have also contributed to die-offs."
What is the history of Karenia in the Northeast?
"Karenia mikimotoi was first isolated from a coastal lagoon near Woods Hole, MA in 1957 and classified at that time as Gyrodinium aureolum. Since this time, large scale blooms of K. mikimotoi appear to be an emerging problem in New England, with the first occurrence in Maine reported in August, 2017. This bloom was concentrated in the Fore River, Portland Harbor, and parts of the Harpswell coastal waters, and coincided with a die-off of softshell clams in Brunswick, ME. This mortality event cost fishermen $250,000, but a direct causal link between the bloom and shellfish mortality was not established. In August 2019 another bloom occurred in Casco Bay, with no mortalities recorded. Karenia mikimotoi is periodically found in Massachusetts waters, usually in the summer and early fall."

"Many people living in or near impacted areas told the ABC they felt they had been left in the dark by authorities.
"While state government bodies including SA Health, the Department of Primary Industries and Regions, South Australia (PIRSA) and the EPA have issued information on their websites and through the media, a lack of information in the days and weeks after the bloom prompted a movement of citizen scientists to collect their own samples and share their findings online."
