Climate change signals a whale of a shift in feeding patterns
Every summer and fall, endangered North Atlantic right whales congregate in the Bay of Fundy between Nova Scotia and New Brunswick to gorge on zooplankton. Researchers have documented the annual feast since 1980, and well over 100 whales typically attend, a significant portion of the entire species. Only this year, they didn’t. Just a dozen right whales trickled in—a record low in the New England Aquarium’s 34-year-old monitoring program. And that comes on the heels of two other low-turnout years, 2010 and 2012.
Numbers of the critically endangered marine mammal have been ticking up in recent years just past 500 individuals, so no one thinks the low turnout in the Bay of Fundy augurs a decline in the species as a whole. The right whales must have gone elsewhere. But where? And more importantly, why?
“Our whales have been missing in their normal habitat areas, where we’ve learned to expect them over three and a half decades,” says Moira Brown, a senior scientist at the aquarium who runs the monitoring program. “It’s quite shocking when you go out there day after day after day and you don’t see any right whales.”
