Algae bloom is source of pond?s green appearance

page5a199PHILIPSBURG--The green appearance of Great Salt Pond caused some concern throughout yesterday, Monday.

St. Maarten Nature Foundation conducted some tests on the pond water's content and discovered high levels of phosphate, which indicated a rampant algae bloom. Nitrogen levels also appeared high, indicating low levels of oxygen in the water, which also contributes to the algae bloom.

According to Marine Park Manager Tadzio Bervoets, the low level of oxygen in the pond is a threat, as it enables a breeding ground for the already plaguing midges and mosquitoes.

Moreover, he explained that the increase in phosphate levels could be related to the lack of movement in the pond, as a shortage of rainfall has not provided fresh water in the pond. Therefore, he said, if it does not rain soon there could be a surge in the number of dead fish.
