February 16, 2023 — The waters off New England, which are home to rare whales and most of the American lobster fishing industry, logged the second-warmest year on record last year.
The Gulf of Maine, a body of water about the size of Indiana that touches Maine, New Hampshire, Massachusetts and Canada, is warming faster than the vast majority of the world’s oceans. Last year fell short of setting a new high mark for hottest year by less than half a degree Fahrenheit, said scientists with the Gulf of Maine Research Institute, a science center in Portland.
The average sea surface temperature was 53.66 degrees Fahrenheit, more than 3.7 degrees above the 40-year average, the scientists said. The accelerated warming is changing an ecosystem that’s host to numerous important commercial fishing industries, especially for lobsters, they said.
One implication is that the warming is driving species more associated with southern waters into the Gulf of Maine and altering its food chain, said Janet Duffy-Anderson, chief scientific officer with the institute. That includes species such as black sea bass, which prey on lobsters.
