    • GoM Coastal Biopsy Surveys - NRDA

    Metadata Updated: April 1, 2026

    Small vessel surveys were conducted within estuarine and nearshore coastal waters of Barataria Bay, LA and Mississippi Sound, MS to collect tissue biopsy samples from bottlenose dolphins. Visual surveys are conducted to find bottlenose dolphin groups, and then close approaches are made to collect tissue samples using specialized darts that are deployed using either air rifles or crossbow. Photographs are collected during the encounter to identify individuals and document the response to the sample collection. The skin and blubber samples collected support genetics, stable isotope, and contaminant analyses. These data have been used to delineate different stocks of bottlenose dolphins in estuaries of the Gulf of Mexico to support the injury assessment related to the Deepwater Horizon oil spill.
