State Investigating Possible Algal Bloom in Coastal Waters

The state Bureau of Marine Water Monitoring is analyzing ocean water samples to identify the source of chlorophyll in water along the coast, state environmental officials said yesterday.

Chlorophyll, a pigment found in plants, was detected by sensors during a routine surveillance flight over the coast, the New Jersey Department of Environmental Protection (NJDEP) said Monday on the website of its Cooperative Coastal Monitoring Program.

High levels of chlorophyll in water signify an algal bloom.

The graphic posted on the NJDEP's Chlorophyll Remote Sensing page shows levels on June 12 were greater than 50 ug/L (micrograms per liter), which is the highest reading on a scale in which the lowest reading is 0 to 3 ug/L.

Masses of dead, decaying algae can deplete oxygen in the water, causing marine life to die or leave the affected area, according to the National Ocean Service, which is part of the National Oceanic and Atmospheric Administration.

Meanwhile, beach and water conditions appeared good despite elevated levels of chlorophyll along the coast, environmental officials said.
