It all seems pretty bleak. On a scale that's hard to comprehend. But giving up is a disservice to the victims and a betrayal to the survivors, who need us to stop the offshore gas, seismic blasting, and rising dam walls. Because we can restore what has been destroyed and care for the waters the way they deserve.

Toxic Algal Blooms enlarges. (July 2025)

Data gathering for South Australia 2025 marine mortality events. This project is set to automatically add aquatic vertebrates and macroinvertebrates annotated 'dead' from Feb 2025 onwards. While some unrelated records are automatically added, the majority of records should reflect marine mortalities associated with the extended harmful algal bloom (HAB) in South Australia.
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."

@miki_lou "The new study details a timeline of algal bloom observations in Great Slave Lake, confirming they are a new phenomenon and becoming more frequent.
" 'This was quite a surprising result,' Cederwall said.
" 'It’s quite the unusual type of blooms that we’re seeing up here and kind-of the rapid change that we’ve been seeing.' "

Advocacy group challenges “new normal” status of Lake Erie’s algal blooms
Alliance for the Great Lakes calls for use of enforceable regulations to prevent toxic algal blooms. Michigan agency says the state has limited regulatory authority and defends the state’s actions.#algalblooms #drinkingwater #lakeerie

@bouriquet You know, I thought that could be a solution, but some folks in Australia are thinking that might not be a good idea.
#Desalination and #AlgalBlooms
24 May, 2025
"The recent activation of the #Adelaide desalination plant and the coincidental toxic algal bloom causing the widespread deaths of marine fauna is cause for concern. As shown by the chlorophyll map above, the bloom including the toxic marine alga #KareniaMikimotoi occurred close to the Adelaide plant which discharges brine and maintenance chemicals into a relatively sheltered nearshore environment. Notably, to reduce harmful impacts, dispersion jets are used to rapidly dilute brine and potentially toxic chemicals at the point of discharge. In doing so, the strong jets can mobilise sediments and release nutrients and previously dormant cysts of toxic algal species including algae causing the current devastating bloom. The disturbance to nearshore sediments, and conditions favourable for rapid increase in the growth of toxic algae such as elevated temperature, nutrients, and sunlight, present plausible causes of the bloom. Such conditions are likely to be more prevalent with climate change. Public statements which exclude or aim to diminish the role of desalination discharge as a cause are inconsistent with desalination plants elsewhere in the world which have been associated with harmful algal blooms. This underscores the considerable risk presented by a proposed desalination plant off Port Lincoln which is adjacent to a designated aquaculture zone. It is generally recommended that desalination plants be situated on high energy coastlines away from valuable biological resources."

An action I was recently involved in at the Department for Environment and Water.
Holding a space of mourning for all the sea kin lost to the lethal algal blooms that spread vastly across the South Australian coasts.
