Microalgae bloom on SA shores

Parts of South Australia continue to be affected by the ongoing microalgae bloom, Karenia mikimotoi.

The naturally occurring bloom continues to affect beaches on the Fleurieu Peninsula, and Kangaroo Island and is increasingly prevalent along the southern coast of the Yorke Peninsula.

This is a dynamic situation as the bloom travels depending on weather and water conditions and the impact on people in these areas can therefore be unpredictable.

The event is likely being driven by an ongoing marine heatwave impacting southern Australian waters, with water temperatures currently 2.5C warmer than usual, as well as relatively calm marine conditions with little wind and small swells.

But how do microalgal blooms and marine heat waves occur?
