Can the Ocean Bounce Back? Healing After Harmful Algal Blooms
South Australia is currently experiencing an unprecedented and devastating harmful algal bloom (HAB) of the species Karenia mikimotoi, impacting large areas of its coastline, including metropolitan beaches, the Fleurieu Peninsula, Yorke Peninsula, Kangaroo Island, Eyre Peninsula, and the Coorong…
The HAB: do we dare consider future scenarios?
The devastating Karenia mikimotoi algal bloom in South Australia is not just a current crisis; it presents alarming future scenarios for the state’s precious marine ecosystems and industries. While the immediate impacts are profound, the long-term consequences could be even more far-reaching, especially given the unique characteristics of Karenia and South Australia’s environment…
Monitoring for the future
South Australia’s ongoing HAB reflects the growing convergence of climate-related and local environmental pressures, including marine heatwaves, nutrient-rich flood discharge, stormwater runoff, and seasonal upwelling. In this article I briefly summarise the previous articles and extend the critical thinking to propose a monitoring system that meets the present and future needs…
Recognising the scientists responding to South Australia’s Harmful algal bloom
While headlines focus on dead fish and discoloured waters, dozens of scientists and citizen scientists are working quietly and tirelessly. They’re the researchers wading into chilly winter oceans to collect water samples; the modellers running particle-trajectory forecasts late at night; the lab teams typing up toxin assays before dawn…
