The study area, covering approximately 39,200 nmi2, was in the slope waters from Chesapeake Bay, VA to Cape Cod, MA. Most of the survey was between 10 nautical miles (nmi) inshore of the 50 fathom contour and 10nmi offshore of the 1000 fathom contour. This survey was part of a large scale marine mammal sighting survey which consisted of two legs (each approximately a month long) where two ships were used during each leg, with an addition leg in which a plane was used to survey for six weeks. The entire study area was from Chesapeake Bay, VA, USA to the Gulf of St. Lawrence, Canada.
