Algal bloom in Simpson Bay Lagoon.
COLE BAY–Nature Foundation is monitoring the spread and extent of a harmful algal bloom in the Cole Bay corner section of Simpson Bay Lagoon. Harmful algal blooms (HABs) occur when colonies of algae – simple plants that live in the sea and fresh water – grow out of control while producing toxic or harmful effects on people and wildlife.
“It started out small but unfortunately over the past few days we have noticed an increase in the extent of the bloom,” said Nature Foundation Manager Tadzio Bervoets in a press statement.
Although there have not been any signs of fish kills or human impacts yet, the foundation is monitoring the situation closely, considering the potential for harmful effects caused by the bloom.
“Right now, we hope that the conditions will stabilise which will allow the bloom to dissipate. However, considering the potential for harmful impacts we will be keeping a close eye on the situation,” said Bervoets.
Harmful algal blooms occur when nutrients (mainly phosphorus, nitrogen, and carbon) from sources such as sewage and wastewater “overfeed” the algae that exist normally in the environment, causing the algae to bloom.
“Unfortunately, this is an example of poor water quality leading into a wider issue within our environment. In addition to this bloom we are also struggling with the health of our coral both on the reefs and within our coral nursery. This issue highlights the need for addressing our wastewater management on the island,” said Bervoets.
