The Northeast Fisheries Science Center (NEFSC)’s aerial survey team has been in the air, weather and conditions permitting, the past few weeks looking for marine mammals, especially North Atlantic right whales, and other whale species. The aircraft flies at an altitude of 750 feet and is often in the air 6 hours, sometimes a bit longer.
The NOAA Twin Otter, flying out of the Hyannis Airfield, has had a variety of sightings in recent weeks, among them a rare bowhead whale. It’s been a crazy few weeks!
On April 18 they saw 1 minke whale in Rhode Island Sound. During a survey of Stellwagen Bank and Wilkinson Basin the following day, April 19, the aerial science crew of Tim Cole, Pete Duley and Allison Henry sighted 1 bowhead whale, 6 humpback whales, 7 fin whales, 3 minke whales, 2 pilot whales, 2 common dolphins, and 44 Atlantic white-sided dolphins. On April 21, the team sighted 40 white-sided dolphins on Cashes Ledge. Another aerial survey on April 30 of Jordan Basin and Jeffreys Bank sighted 1 fin whale.

On May 6, 7, and 8 the same aerial science team surveyed the Great South Channel area and areas known as SCOPEX North and South.
The team’s May 6 aerial survey, lasting 7 and a half hours, of Great South Channel and SCOPEX South was a busy one. The team saw 15 humpback whales, 7 fin whales, 11 sei whales, 8 minke whales, 3 pilot whales, 11 common dolphins, 41 Atlantic white-sided dolphins, 1 harbor porpoise. and 38 right whales.
