Whales and dolphins aplenty

Nineteen North Atlantic right whales were sighted during the May 12 aerial survey of Howell Swell. Thirteen of the whales were seen subfeeding and their position relayed to  the NOAA Ship Gordon Gunter, which is conducting the annual right whale survey and biology cruise in the Gulf of Maine. The group included 1 tagged whale. The other six whales were subfeeding and breaching.  Howell Swell is an undersea feature east of Cape Cod in the Gulf of Maine.

The three and a half-hour survey flight also observed 2 sei whales, 132 Atlantic white-sided dolphins, 35 harbor porpoise, and 16 basking sharks.

May 11 was another beautiful spring day. The NOAA Twin Otter with the NEFSC aerial survey team aboard flew in Howell Swell again and sighted 14 right whales, 13 of them subsurface feeding. Their positions were related to the Gordon Gunter.

During the more than five-hour survey the team also observed 3 sei whales, 137 Atlantic white-sided dolphins, 25 harbor porpoise and 11 basking sharks.
