Title: Atlantic Marine Mammal Assessment Vessel Surveys
Status: In Work
Abstract:

These data sets are a compilation of large vessel surveys for marine mammal stock assessments in South Atlantic (Florida to Maryland) waters from 1994 to the present. These are designed as line-transect surveys which typically follow a double saw-tooth pattern covering waters between the continental shelf break (approx. 200m depth) and the U.S. Economic Exclusivity Zone. Visual survey data are collected following standard protocols and are intended for analysis using the line-transect Distance method to provide estimates of abundance for marine mammal stocks within the survey area. Each survey includes a collection of data sets including visual survey data (survey effort and sightings of marine mammals and other species), passive and active acoustics data, sample collection information, and physical oceanographic data. These data have been used to develop estimates of population size for target species for use in annual Marine Mammal Protection Act stock assessment reports.

Purpose:

To assess the abundance and spatial distribution of cetaceans in the surveyed area.

Access Information

Security Class: Unclassified
Data Access Procedure:

The data will be available from a public web server once an access methodology has been developed.

Data Access Constraints:

None

Data Quality

Quality Control Procedures Employed:

Visual sightings are reviewed by lead observers and the field party chief at sea to verify species identifications and group size counts. Effort and sightings data from digital records are reviewed post-survey and compared to field notes and error logs. Corrected survey effort shapefiles are visually reviewed and verified.
