Description

Original provider: NOAA Southeast Fisheries Science Center (SEFSC) Dataset credits: NOAA Southeast Fisheries Science Center (SEFSC) Abstract: As part of the AMAPPS program, the Southeast Fisheries Science Center conducted an aerial survey on the continental shelf waters of the US east coast, from Virginia to the Florida Keys. The survey was conducted between 7 December 2019 and 25 January 2020 aboard a NOAA Twin Otter aircraft. Survey tracklines were oriented perpendicular to the shoreline and latitudinally spaced 20 km apart. 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 survey was designed for analysis using Distance sampling and a two-team (independent observer) approach to correct for perception bias in resulting abundance estimates. Due to unfavorable weather conditions (mainly fog and heavy winds) throughout the survey the northernmost area surveyed was off the Virginia coast. In addition, from northern South Carolina to VA, several segments of the proposed tracklines were not surveyed due to military exercises being conducted over the area. Purpose: The main goal of this survey was to assess the distribution and abundance of marine mammals and sea turtles in the US east coast. Supplemental information: Perpendicular distance to the animal is not publicly available. The dataset is accompanied by transect (effort) data which is provided as a separate file. 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.
