The survey was conducted during 2017 between 17 April and 20 May aboard a NOAA Twin Otter aircraft at an altitude of 600 feet (183 m) and a speed of 110 knots. Survey tracklines were oriented perpendicular to the shoreline and latitudinally spaced 20 km apart. “Fine-scale” tracklines were surveyed closer to the shores of NJ, DE and VA over renewable energy leasing areas. The survey was designed for analysis using Distance sampling and a two-team (independent observer) approach to correct for perception bias in resulting abundance estimates.
