Algae proliferation in the lagoon: an indicator of pollution?


The Sint Maarten Nature Foundation indicates that it has been monitoring the proliferation of algae in the lagoon of Simpson Bay for several weeks.

Boaters would have complained that these algae obstructed the air intakes of their engine and that they would have caused the death of some fish.

After two research dives in the lagoon, the Sint Maarten Nature Foundation considers that it is probably the algae Ulvaria oxysperma and Ulva Linza: two species indicating an increase in pollution levels and a decrease in the water quality of the lagoon.

"We are trying to determine whether the current proliferation of algae is linked to the effects of hundreds of boats and other types of infrastructure sunk or damaged after hurricanes Irma and Maria," says the foundation.
