Officials in Tasmania are striving to determine a pink slime that has materialized on a remote shoreline, with some scientists concerned it could be an algae outbreak.
The pink-tinged sludge materialized across a stretch of a coastal area about 37 miles south of the capital. A like substance has also been recorded on areas of another local beach and an additional coastal site.
Examples have been gathered and submitted to the Environment Protection Authority for examination. A spokesperson commented that "algae outbreaks are a natural occurrence in response to shifts in minerals, temperature, rain or light".
"The events are occasionally called crimson or rosy tides because the outbreaks can turn the water reddish," the official noted. "Few algae outbreaks are toxic, with numerous types functioning as a key source of energy for creatures in the aquatic ecosystem."
"The usual source of reddish water in local waters is the sea plant Noctiluca scintillans, which can create luminous nighttime effects at night."
Phytoplankton proliferations occur naturally but their frequency has increased in recent times, partly due to global warming and environmental waste that join together to create food-loaded oceans primed for the rapid spread of dinoflagellates.
Dinoflagellates are a phytoplankton species that normally act as the ocean's garbage cleaners. During a outbreak, there is a rapid growth in their colonies that disrupts the healthy balance of marine environments.
These events have been likened to underwater bushfires and can keep expanding as long as conditions are ripe. In worse situations, sensitive marine ecosystems can be devastated as aquatic animals is destroyed or deprived of oxygen, providing more minerals for the proliferation.
A southern state recently confronted a catastrophic algae outbreak along its southern coastline after a string of marine heatwaves, which expanded across a vast area. The event resulted in 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 government calculations.
A marine expert, who was involved in studying the beginning of South Australia's algal bloom stated, based on images of the local event, the most likely species involved was Noctiluca scintillans, a type of dinoflagellate also known as "ocean glitter".
"There are numerous of these events around Tasmania of late," she remarked.
The expert said the algae did not generate poisons like the organism involved in that devastating algal bloom, but it does consume microscopic animals and "many fish eggs", meaning fish and crustacean species were in greatest danger.
"You usually see a outbreak of the organism after a bloom of another organism, or something like a fish reproduction," she added.
Lilly Henley, who gathered specimens of the magenta ooze in Tasmania, stated it looked like the possible outbreak had "increased notably" and proposed the salmon farming industry was the probable cause, pointing to similar cases in other places.
"Therefore the state needs to issue a firm alert here, the government and the regulators need to respond to this. We need to analyse the specimens we've gathered and we need to notify the community here," she emphasized.
The scientist said she had worries for public safety after feeling a tingling sensation along her limbs and skin while being exposed with affected seawater.
An environmental foundation has reported dead octopus and dead sea cucumbers being found on the beach, with a prominent conservationist labeling the situation as an "environmental emergency" and demanding the state premier to visit and "take control the effort that officials must be undertaking".
"Officials needs to realize this is a disaster in the making, financially as well as for nature."
Addressing journalists, the premier commented he was uninformed of any links between the algae outbreak and the salmon industry, emphasizing laboratory analysis was required before determinations could be drawn.
"We need to ensure our waterways are ecologically sound and sustainable," he added.
"Our coastal assets across the state are our resources and we need to guarantee the people and our business sector can coexist to enjoy our seas effectively and in a lasting way."
