Description

Original provider: NOAA National Centers for Environmental Information Dataset credits: Errol Ronje, NOAA National Centers for Environmental Information Texas Marine Mammal Stranding Network National Marine Fisheries Service Southeast Fisheries Science Center Abstract: As part of the marine mammal stock assessment program of the National Marine Fisheries Service (NMFS), photographic identification capture mark recapture data were collected to estimate the abundance of common bottlenose dolphins (Tursiops truncatus) by the Southeast Fisheries Science Center, Pascagoula, Mississippi Laboratory, and the Texas Marine Mammal Stranding Network from 2014-03-29 to 2019-06-28. This dataset includes spatiotemporal data for visual observations and dorsal fin images for individual dolphins encountered in the coastal and estuarine waters of north Texas and western Louisiana including East Matagorda Bay, West Bay, Galveston Bay, and Sabine Lake. Purpose: The Marine Mammal Protection Act of 1972 requires the National Marine Fisheries Service (NMFS) to report the status of all marine mammal stocks in USA waters. The primary purpose of this dataset was to collect common
bottlenose dolphin encounter data for capture-mark-recapture abundance estimation models and to assess the spatial distribution of the dolphin group encounters to inform stock assessment reports in three NMFS designated stock areas: West Bay, Galveston Bay, and Sabine Lake. Supplemental information: Fin images are included in the downloadable zipped file.
