Shock sweeps Port Noarlunga Beach, Adelaide, as a mountainside of dangerous sea foam arrives ashore
In the coastal town of Port Noarlunga, located in Adelaide's south, a hazardous sea foam mass has washed up on the beach, causing concern among locals and visitors alike. The foam, creeping into the Onkaparinga River and potentially spreading into inland waterways, has been a recurring sight since March.
The cause of this sea foam and the accompanying algal bloom has not been definitively identified. However, during blooms, sea foam can serve as a sign that algal toxins are present. Scientists suggest that the toxic sea foam at Port Noarlunga Beach is caused by the accumulation of organic matter, pollutants, and nutrients, which promote excessive algae growth, leading to harmful algal blooms that create the foam.
Large harmful algal blooms can have impacts on both human health and the environment. Beachgoers are advised to avoid swimming or surfing in foamy or discoloured water at Port Noarlunga Beach. Exposure to large amounts of sea foam could potentially cause health issues, according to scientists. Popping sea foam bubbles during a bloom can cause algal toxins to become airborne, potentially irritating the eyes and posing a health risk for those with asthma or other respiratory conditions.
The updated advice urges people with asthma to carry their medication when visiting coastal regions. Social media continues to be flooded with photos of the sea foam and images of dead sea life from the ongoing algal bloom on Australia's south coast. Locals have attributed the increased sea foam to the presence of more algae in the ocean.
Authorities have warned residents about potential symptoms like eye irritation and coughing. They advise the public to stay informed and follow any safety guidelines issued by local health and environmental agencies. As the investigation into the cause of the algal bloom continues, the community remains vigilant, closely monitoring the situation and taking necessary precautions to ensure their health and safety.
