Sea sparkle blooms again between Point Lonsdale and Torquay

THE Department of Environment, Land, Water and Planning has detected another bloom of “sea sparkle” off the coast, with this event affecting marine waters between Point Lonsdale and Torquay.

There have been several occurrences of the algae, scientifically known as Noctiluca scintillans, off beaches along the Surf Coast and Bellarine Peninsula over the past three months, including in Lorne in October.

DELWP regional agency commander Aaron van Winden said the blooms were predominantly one to two kilometres offshore and spread sporadically from Point Lonsdale to Torquay.

“The bloom does not appear to be impacting local beaches at this time. However, we are monitoring the situation closely for any changes.

“When present, blooms produce a spectacular glowing light at night, however, as a precaution, members of the public are advised to avoid direct contact with affected water.

“Direct contact may cause allergic reactions such as skin rashes or itchiness, sore ears or nose, or if swallowed, gastroenteritis, nausea and vomiting.

“Wash immediately with fresh water if you do come in contact with sea sparkle and seek medical advice if experiencing illness after contact with affected water.”

Sea sparkle is one of the most commonly occurring bioluminescent organisms in the world, and during blooms, can produce toxic levels of ammonia that can lead to fish deaths.

Blooms can look like a murky, sludge or oil-like substance floating in marine waters and washing onto beaches.

Affected water can become temporarily discoloured and have an unpleasant smell. DELWP says it is monitoring coastal waters for blooms and will provide further information as the situation changes.
