Authorities in the island state are working to identify a pink slime that has appeared on a isolated coast, with some scientists worried it could be an phytoplankton proliferation.
The magenta-hued slime was found on a stretch of Randalls Bay about 60km south of the city. A comparable ooze has also been noted on areas of another local beach and Little Taylors Bay.
Specimens have been taken and sent to the Environment Protection Authority for examination. A representative stated that "phytoplankton proliferations are a natural event in reaction to changes in food sources, warmth, precipitation or sunlight".
"They are at times called red or pink tides because the blooms can color the water red," the representative added. "Only some algal blooms are harmful, with numerous types functioning as a primary source of nourishment for creatures in the marine food web."
"The most common cause of crimson tides in these seas is the marine phytoplankton Noctiluca scintillans, which can produce bioluminescent light displays at night."
Algae outbreaks occur naturally but their rate has grown in recent times, in part due to global warming and pollution that join together to create food-loaded oceans ideal for the fast proliferation of dinoflagellates.
Dinoflagellates are a type of algae that typically function as the ocean's waste processors. During a proliferation, there is a fast increase in their populations that disturbs the normal functioning of aquatic systems.
These phenomena have been compared to subsurface wildfires and can persist in growing as long as the environment is suitable. In more extreme scenarios, delicate ocean habitats can be destroyed as sea creatures is eliminated or deprived of oxygen, supplying more minerals for the bloom.
South Australia recently confronted a devastating phytoplankton proliferation along its southern coastline after a series of oceanic warm spells, which expanded across a vast area. The event resulted in swimmers with sore eyes and persistent coughs and may have caused the death of up to numerous aquatic species across numerous types, according to government calculations.
Faith Coleman, who was involved in studying the start of the previous algal bloom commented, based on photos of the local event, the likely culprit involved was Noctiluca scintillans, a form of dinoflagellate also known as "marine shimmer".
"There have been lots of these blooms around the island of late," she remarked.
The scientist explained sea sparkle did not generate harmful substances comparable to the organism involved in the previous severe event, but it does eat small invertebrates and "numerous fish eggs", meaning aquatic creatures were most at risk.
"You usually see a proliferation of the organism after a proliferation of another organism, or something like a salmon or coral spawning event," she noted.
Lilly Henley, who collected samples of the magenta ooze in Tasmania, said it looked like the possible outbreak had "expanded greatly" and suggested the aquaculture sector was the probable cause, pointing to similar cases in other places.
"Therefore the state needs to issue a strong warning here, the officials and the EPA need to react to this. We need to study the examples we've gathered and we need to put word out the public here," she stated.
Henley expressed she had concerns for people's well-being after experiencing a prickling feeling along her body while being sprayed with tainted seawater.
An environmental foundation has documented deceased sea creatures and deceased marine life washing ashore, with a longtime environmental campaigner calling the circumstances as an "environmental emergency" and urging the state premier to visit and "assume command the reaction that officials must be making".
"The leader needs to know this is a catastrophe in the making, economically as well as environmentally."
Speaking to reporters, the leader stated he was not aware of any relationships between the event and the farming business, stating scientific testing was needed before judgments could be reached.
"We need to ensure our rivers and seas are ecologically sound and long-lasting," he said.
"Numerous shorelines across Tasmania are our treasures and we need to make sure the people and our business sector can live together to enjoy our seas productively and sustainably."
