Invasive seaweed threatens Gulf of Maine

The study focused on the shifting seaweed population only and did not concentrate on the cause. But Dijkstra said warming water temperatures do play a part in the decline of kelp.

“Kelp tissues tend to decline at warmer water temperatures,” she said, as determined in a 2015 Canadian study.

She referenced a 2013 Gulf of Maine Research Institute study reporting that between 2004 and 2012, sea surface temperatures rose as much as 0.5 degrees Fahrenheit a year.
