AMAPPS Southeast Aerial Cruise Spring 2017 at OBIS-SEAMAP

As part of the AMAPPS program, the Southeast Fisheries Science Center conducted aerial surveys of continental shelf and slope waters (up to the 2,000 m isobath) along the US east coast from New Jersey to Florida. 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.

The main goal of this survey was to assess the distribution and abundance of marine mammals and sea turtles in the US east coast.

The funds for this project came from the Bureau of Ocean Energy Management (BOEM) and the US Navy through the respective Interagency Agreements for the AMAPPS project. Flight time and other aircraft costs were funded by NOAA Aircraft Operations Center. Staff time was provided by the NOAA Fisheries Service, Southeast Fisheries Science Center and NOAA Aircraft Operations Center. We would also like to thank the airplane’s crew and observers that were involved in collecting these data.

The data provided was only from one of the two observation teams.

Only data for marine mammals and sea turtles was provided and none of the opportunistic sightings of other species.

A portion of the proposed tracklines off the southern coast of Georgia was not surveyed due to restricted airspace from military exercises
