April 16, 2021 — The following was released by NOAA Fisheries:
On March 21, 2021, 89 North Atlantic right whales were spotted by scientists from the Center for Coastal Studies in Cape Cod Bay. Just a few days later, on March 30, scientists spotted 57 North Atlantic right whales off Southeast New England in and around the wind energy development areas. They were seen by scientists from the Northeast Fisheries Science Center flying a sighting survey. Three mother/calf pairs have been sighted there to date.
Right whales have typically appeared in Cape Cod Bay during spring, but in recent years have been arriving sooner and staying longer. Right whale use of areas south and west of Nantucket Shoals has been documented in just the last 10 years. In recent years, the right whales appear to be staying in these waters in greater numbers and for longer periods than in the past.
What gives? To find out, we track when and where these whales are found throughout the year, using sighting surveys and passive acoustic listening devices.
“A very small portion of the right whale population heads south to the waters off northern Florida and Georgia in the winter—mostly just the moms—to give birth,“ said Tim Cole, a marine mammal researcher and lead of the center’s aerial whale survey team. We try to determine where the rest of the population is and have found them so far this year in large numbers on Nantucket Shoals south of Martha’s Vineyard and Nantucket, and in Cape Cod Bay.”
