The study areas in Leg I and Leg II, respectively, were from Cape Cod. Massachusetts to Virginia, and from Cape Cod, Massachusetts to Halifax, Nova Scotia, Canada. Both study areas extended from the 100 m depth contour to the Gulf Stream.

Secondary objectives included: 1) Collect bongo, CTD, water depth and temperature data to correlate with the spatial distribution of the marine mammals, 2) Conduct marine mammal photographic and video identification studies, and 3) Collect biopsy samples. notPlanned Debi Palka NOAA Northeast Fisheries Science Center Primary contact dpalka@whsun1.wh.whoi.edu NA NA NA Debi Palka owner NA zd_60 2025-07-31T14:03:38-04:00 dataset Palka, D. 2018.
