Agencies in Tasmania are attempting to pinpoint a rosy sludge that has appeared on a isolated coast, with a number of researchers concerned it could be an algae outbreak.

Broad Presence On Shore

The pink-tinged sludge was found on a stretch of Randalls Bay about 60km south of Hobart. A similar sludge has also been recorded on parts of Little Roaring Beach and Little Taylors Bay.

Examples Gathered for Testing

Examples have been taken and provided to the Environment Protection Authority for analysis. A spokesperson remarked that "phytoplankton proliferations are a normal phenomenon in response to changes in minerals, temperature, precipitation or light".

"These blooms are sometimes called red or pink tides because the outbreaks can change the water red," the spokesperson noted. "Few algal blooms are harmful, with several kinds serving as a primary source of energy for animals in the marine food web."

"The most common cause of reddish water in local waters is the sea plant Noctiluca scintillans, which can create glowing light shows at night."

Increasing Occurrence Connected to Climate Change

Algal blooms occur naturally but their occurrence has grown in recent times, in part due to climate change and pollution that join together to create mineral-filled seas ideal for the rapid spread of dinoflagellates.

Dinoflagellates are a phytoplankton species that normally serve as the ocean's garbage cleaners. During a bloom, there is a fast increase in their colonies that disrupts the normal functioning of marine environments.

These occurrences have been compared to marine infernos and can continue to grow as long as conditions are ripe. In more extreme scenarios, delicate ocean habitats can be devastated as sea creatures is destroyed or deprived of oxygen, providing more minerals for the outbreak.

Past Devastating Bloom in South Australia

South Australia recently confronted a devastating algae outbreak along its southern shore after a succession of sea temperature spikes, which expanded across thousands of square kilometres. The outbreak caused surfers with irritated eyes and severe coughing and may have caused the death of up to numerous aquatic species across 400 different species, according to government calculations.

Specialist Assessment on the Local Situation

Faith Coleman, who assisted in examining the onset of South Australia's outbreak said, based on pictures of the local event, the likely culprit involved was Noctiluca scintillans, a form of dinoflagellate also known as "ocean glitter".

"We have seen numerous of these blooms around Tasmania of late," she remarked.

Coleman explained sea sparkle did not generate toxins like the species involved in that harmful algal bloom, but it does eat microscopic animals and "numerous fish eggs", meaning marine life were particularly vulnerable.

"Typically one notices a outbreak of the organism after a proliferation of another organism, or something like a fish reproduction," she said.

Calls for Investigation and Public Safety

Lilly Henley, who gathered specimens of the rosy slime in the state, commented it appeared the potential proliferation had "increased notably" and proposed the salmon farming industry was the most likely culprit, pointing to comparable events elsewhere.

"Therefore Tasmania needs to send a firm alert here, the authorities and the regulators need to respond to this. We need to examine the samples we've taken and we need to notify the community here," she emphasized.

She said she had worries for people's well-being after noticing a numbness along her limbs and skin while being exposed with tainted seawater.

Claims of Deceased Animals and Calls for Government Action

An environmental foundation has documented dead octopus and deceased marine life appearing on the coast, with a longtime environmental campaigner calling the situation as an "natural disaster" and demanding the local leader to see and "take control the response that officials must be undertaking".

"Officials needs to realize this is a crisis in the happening, commercially as well as ecologically."

Official Response

Addressing reporters, the premier commented he was not aware of any connections between the algae outbreak and the salmon industry, stating scientific testing was necessary before determinations could be reached.

"We need to ensure our waterways are ecologically sound and sustainable," he remarked.

"Our coastal assets across Tasmania are our treasures and we need to guarantee the community and our industry can coexist to enjoy our seas effectively and sustainably."
