This dataset contains spatiotemporal data from the "NorTex" catalog, including 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.

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. irregular Errol Ronje Errol Ronje Primary contact errol.ronje@noaa.gov https://orcid.org/0000-0003-3312-5662 NA NA NA Errol Ronje owner Heidi Whitehead originator NA zd_2166 2025-09-11T15:58:17-04:00 dataset Ronje, E. and H.
