AMAPPS Southeast Aerial Cruise Winter 2015 at OBIS-SEAMAP

As part of the AMAPPS program, the Southeast Fisheries Science Center conducts aerial surveys of continental shelf waters along the US east coast from Cape Canaveral, Fl to Cape May, NJ. 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 goal of the survey was to conduct line-transect surveys using the Distance sampling approach to estimate the abundance and spatial distribution of marine mammals and turtles in waters over the continental shelf (shoreline to 200m isobaths) from Florida to New Jersey.

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

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

Due to weather conditions during the survey, a few areas of the study area were not surveyed.

Data were further audited in 2018 since publication of Annual Report in 2015
