The Red Tide

Fancy a dip?



A fresh concentration of red tide algae forced the closure of another ten Sydney beaches as government authorities warned new blooms could occur anywhere between Sydney and the Central Coast.

“This bloom has likely occurred as a result of the upwelling of nutrient-rich deep ocean water on to the continental shelf,” they said.

“Testing of samples taken from Bondi beach have been identified as noctiluca scintillans, which appears as a pinkish to reddish discoloration in water. Upwellings create food sources for the predatory noctiluca scintillans – there’s more bacteria and phytoplankton for them to eat,” Dr Murray said.
