The survey was conducted during 2015 between 23 January and 3 March. It was conducted along tracklines oriented perpendicular to the shoreline that were latitudinally spaced 20 km apart aboard a NOAA Twin Otter aircraft at an altitude of 600 feet (183 m) and a speed of 110 knots. The survey was designed for analysis using Distance sampling and a two- team (independent observer) approach to correct for visibility bias in resulting abundance estimates. The survey covered waters from Cape May, NJ to Cape Canaveral, FL including “fine-scale” tracklines in waters offshore of New Jersey. The majority of survey effort occurred in waters from Cape Hatteras, NC and south. Due to weather conditions during the survey, a few areas of the study area were not surveyed.

The dataset is accompanied by transect (effort) data which is provided as a separate file. Data were further audited in 2018 since publication of Annual Report in 2015. Sightings included were detected on-effort by the forward team only; you may request the full dataset and sightings including opportunistic ones directly to the provider.
