Large algae bloom stretches from Maine to Massachusetts

A large algae bloom stretching from the Gulf of Maine to the Massachusetts coast is being monitored by scientists who are studying its potential effects on marine life.

The bloom was detected several weeks ago and remains under observation. Scientists are particularly interested in its potential impact on shellfish and finfish.

Elizabeth Harvey, associate professor and chair of the Department of Biological Sciences at the University of New Hampshire, told WCVB the bloom does not pose a direct threat to people. But the particular species of phytoplankton involved can potentially harm marine organisms.

The bloom is notable because of its size. Satellite imagery cited by WGME shows the bloom extending along much of the Maine coast and potentially reaching from Penobscot Bay south toward New Hampshire and Massachusetts.

WGME identified the phytoplankton involved as Karenia mikimotoi, a species that can form what scientists call a harmful algae bloom.

Darcie Couture, Harpswell's harbormaster, told WGME that the bloom has affected shellfish and finfish along the Maine coast, with some of the most significant impacts reported around Casco Bay.

The towns of Harpswell and Brunswick have been among the areas affected.

Algae blooms occur in the ocean throughout the year, but WCVB…
