April 16, 2023 — On a breezy spring day, scientists and conservationists methodically conducted experiments near 15 North Atlantic right whales that occasionally spouted and surfaced in a bay south of Boston.
The pod of adults and calves is about 4% of the worldwide population of a marine mammal that almost disappeared from the planet after many decades of commercial whaling. There now are only a few hundred of the behemoths, which can weigh 70 tons (63.5 metric tons) and subsist on small ocean organisms.
Although right whale numbers are dwindling, conservationists attribute their continued survival to the U.S. Endangered Species Act.
The landmark federal law — a half century old this year — has forced the fishing and commercial shipping industries to take important steps to help protect the critically endangered whales. And it’s spurred government agencies and scientists to undertake research.
