Officials in Tasmania are attempting to pinpoint a magenta ooze that has appeared on a isolated coast, with a number of researchers concerned it could be an phytoplankton proliferation.
The rosy-colored ooze materialized across a section of Randalls Bay about 60km south of Hobart. A like substance has also been recorded on sections of another local beach and an additional coastal site.
Specimens have been gathered and submitted to the regulatory body for analysis. A official commented that "algae outbreaks are a natural occurrence in response to changes in minerals, warmth, rain or illumination".
"They are at times called red or pink tides because the proliferations can turn the water crimson," the representative said. "Only some algal blooms are dangerous, with several kinds acting as a primary source of food for creatures in the aquatic ecosystem."
"The usual source of reddish water in these seas is the oceanic algae Noctiluca scintillans, which can cause bioluminescent light displays at night."
Algal blooms occur naturally but their frequency has grown in recent years, partly due to environmental shifts and contamination that join together to create mineral-filled seas primed for the rapid spread of dinoflagellates.
Dinoflagellates are a marine plant that usually function as the ocean's waste processors. During a bloom, there is a fast increase in their populations that disrupts the proper operation of marine environments.
These phenomena have been equated with underwater bushfires and can continue to grow as long as the environment is suitable. In severe cases, vulnerable aquatic environments can be wiped out as sea creatures is killed or deprived of oxygen, offering more nutrients for the proliferation.
Another region not long ago grappled with a devastating phytoplankton proliferation along its coastal region after a succession of sea temperature spikes, which expanded across a vast area. The bloom left surfers with sore eyes and severe coughing and may have caused the death of up to numerous aquatic species across hundreds of species, according to official estimates.
An estuarine ecologist, who was involved in studying the start of the previous outbreak commented, based on photos of the local event, the probable type involved was Noctiluca scintillans, a kind of dinoflagellate also known as "ocean glitter".
"There have been many of these blooms around Tasmania of late," she said.
The scientist stated this organism did not produce poisons comparable to the organism involved in that devastating outbreak, but it does eat microscopic animals and "lots of fish eggs", meaning fish and crustacean species were most at risk.
"Typically one notices a bloom of this algae after a bloom of another organism, or something like a marine breeding," she noted.
A campaigner, who took samples of the rosy slime in Tasmania, said it seemed the potential proliferation had "increased notably" and proposed the salmon farming industry was the most likely culprit, citing like situations in other places.
"Thus we needs to deliver a clear message here, the government and the EPA need to react to this. We need to analyse the samples we've collected and we need to notify the public here," she said.
Henley said she had anxieties for community health after noticing a tingling sensation along her limbs and skin while being exposed with contaminated seawater.
An advocacy organization has stated deceased sea creatures and deceased marine life washing ashore, with a veteran activist labeling the event as an "ecological crisis" and demanding the state premier to see and "lead the reaction that government must be doing".
"Officials needs to realize this is a disaster in the happening, economically as well as for nature."
Speaking to journalists, the official commented he was not aware of any relationships between the algal bloom and the aquaculture sector, saying laboratory analysis was necessary before conclusions could be reached.
"We must make certain our aquatic environments are environmentally safe and long-lasting," he said.
"The 1,200 beaches across the state are our assets and we need to ensure the community and our economy can live together to use our waterways effectively and responsibly."
