Bigelow. The survey area was between 36 and 42N and 65 and 74W, covering waters offshore of the 100m depth contour. There were 2 independent teams targeting marine mammals and sea turtles using line transect sampling techniques, a team targeting targeting sea birds using strip transect sampling techniques, a team monitoring a towed hydrophone array, and a team collecting physical and biological oceanographic data. Track lines were covered at about 10 knots. In Beaufort sea states of six and less, about 5354 km of on-effort track lines were surveyed. Over 1200 groups (16,000 individuals) of cetaceans, 26 groups (27 individuals) of sea turtles and 1977 groups (4677 individuals) of seabirds were recorded.
