South Australia's algal bloom - Overland literary journal

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.

β€œAs 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.”

Four Corners: S2026 Toxic Tide

South Australia's algal bloom is one of the worst environmental disasters in Australian waters, continuing to devastate parts of the coastline. What did the government know about the health risks and what was the public told?

🌊 We blamed fertilizer. Turns out plastic is the quiet lever. Petroleum microfragments thin the grazers, algae scales. The bloom is a systems failure, bottom up plus top down. Food webs as collateral in a polymer economy.

On the other hand, warming waters, stronger stratification, altered currents, and extreme rainfall events all intensify blooms. Plastics may interact with these trends, but temperature and hydrology shifts are foundational drivers.

SA Marine Mortality Events 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 β€œupwelling” 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.' "
