Abstract

These data sets include a compilation of aerial line-transect surveys conducted over continental shelf waters of the Gulf of Mexico since 1992. The majority of these surveys are targeted to assess the abundance and spatial distribution of bottlenose dolphins and sea turtles between the Texas/Mexico border and the Florida Keys. Surveys are conducted in high-winged twin engine aircraft flying at altitudes of 600-750 feet. Visual observations of marine mammals, sea turtles, birds, and other species are recorded including species identifications, counts of animals. Surveys are conducted along line transects oriented perpendicular to the shoreline and follow protocols consistent with analysis using Distance approaches to estimate detection probability and abundance. These data have been used to provide abundance estimates for target species in annual Marine Mammal Protection Act Stock Assessment Reports.

Title: Gulf of Mexico Protected Species Assessment Aerial Surveys
Status: In Work
Abstract:

These data sets include a compilation of aerial line-transect surveys conducted over continental shelf waters of the Gulf of Mexico since 1992. The majority of these surveys are targeted to assess the abundance and spatial distribution of bottlenose dolphins and sea turtles between the Texas/Mexico border and the Florida Keys. Surveys are conducted in high-winged twin engine aircraft flying at altitudes of 600-750 feet. Visual observations of marine mammals, sea turtles, birds, and other species are recorded including species identifications, counts of animals. Surveys are conducted along line transects oriented perpendicular to the shoreline and follow protocols consistent with analysis using Distance approaches to estimate detection probability and abundance. These data have been used to provide abundance estimates for target species in annual Marine Mammal Protection Act Stock Assessment Reports.

Purpose:

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

Notes:

Aerial surveys were conducted during september/october 1992-1996 and the summer and winter of 2007. Survey data include visual observation data sets, photographs, and limited environmental sampling in some cases.

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 the field party chief 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.
