The survey was conducted between 18 May and 24 June of 2019 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. 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. A portion of the proposed tracklines off the southern coast of Georgia was not surveyed due to restricted airspace from military exercises.
