Agencies in Tasmania are working to identify a rosy sludge that has materialized on a isolated coast, with a number of researchers worried it could be an algae outbreak.

Broad Occurrence Along Shore

The pink-tinged sludge was found on a portion of a southern bay about 60km south of the city. A similar sludge has also been noted on sections of a nearby shore and Little Taylors Bay.

Examples Gathered for Analysis

Examples have been gathered and sent to the regulatory body for testing. A representative commented that "algal blooms are a natural event in reaction to variations in food sources, heat, rainfall or sunlight".

"These blooms are at times called red or pink tides because the blooms can color the water reddish," the official added. "Not all algae outbreaks are toxic, with numerous types functioning as a key source of nourishment for marine life in the marine food web."

"The most common cause of reddish water in Tasmanian waters is the marine phytoplankton Noctiluca scintillans, which can create luminous nighttime effects at night."

Increasing Frequency Associated with Global Warming

Phytoplankton proliferations happen naturally but their frequency has grown in the past few years, partially due to global warming and pollution that merge to create nutrient-rich waters ideal for the fast proliferation of dinoflagellates.

Dinoflagellates are a marine plant that usually function as the ocean's garbage cleaners. During a bloom, there is a quick expansion in their colonies that disrupts the proper operation of marine environments.

These occurrences have been equated with marine infernos and can continue to grow as long as conditions are ripe. In severe cases, vulnerable aquatic environments can be wiped out as aquatic animals is destroyed or smothered, offering more nutrients for the outbreak.

Previous Devastating Event in another region

Another region in the past dealt with a devastating algae outbreak along its southern coastline after a succession of oceanic warm spells, which spread across a vast area. The outbreak left swimmers with sore eyes and hacking coughs and may have killed up to 250,000 marine animals across numerous types, according to agency assessments.

Scientist Opinion on the Local Event

A marine expert, who was involved in studying the onset of the previous event said, based on photos of the current situation, the likely culprit involved was Noctiluca scintillans, a kind of dinoflagellate also known as "marine shimmer".

"There have been numerous of these outbreaks around Tasmania of late," she added.

The expert stated sea sparkle did not produce toxins similar to the species involved in that harmful outbreak, but it does eat small invertebrates and "numerous fish eggs", meaning marine life were in greatest danger.

"You usually see a proliferation of the organism after a outbreak of something else, or an event such as a fish reproduction," she noted.

Appeals for Response and Community Health

A marine scientist, who took samples of the rosy slime in the state, commented it seemed the potential proliferation had "grown significantly" and suggested the salmon farming industry was the probable cause, citing comparable events in other places.

"Thus the state needs to send a clear message here, the authorities and the EPA need to act to this. We need to study the examples we've taken and we need to notify the people here," she emphasized.

Henley said she had concerns for public safety after experiencing a tingling sensation along her limbs and skin while being exposed with tainted seawater.

Claims of Lifeless Sea Creatures and Calls for Government Response

An environmental foundation has stated deceased sea creatures and expired organisms washing ashore, with a veteran activist labeling the circumstances as an "natural disaster" and demanding the government head to inspect and "take control the response that authorities must be undertaking".

"The leader needs to know this is a crisis in the making, financially as well as for nature."

Leadership Response

Addressing journalists, the leader commented he was not aware of any links between the algae outbreak and the salmon industry, saying scientific testing was required before determinations could be made.

"It is vital to guarantee our rivers and seas are ecologically sound and sustainable," he said.

"The 1,200 beaches across Tasmania are our resources and we need to ensure the public and our economy can coexist to enjoy our aquatic resources productively and sustainably."
