Blue Green Algae Plumes

12 Dec 2014

During the wet season the NT EPA regularly receives reports of oily, frothy or jelly-like slicks along beaches or in the water.

These slicks are often caused by plumes of blue green algae (commonly of the genus Trichodesmium). Blue green algal plumes are a common natural phenomenon in Territory waters during the early wet season.

These algae may contain toxic properties and cause skin irritations. The NT EPA recommends people, and their dogs, stay out of the water when plumes are present.

A fact sheet is available on the NT EPA website:
