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.
