Galveston Bay, Texas is a busy place. It houses the sixth largest port and the second largest petro-chemical compound in the world, as well as commercial and recreational fisheries. The bottlenose dolphins that inhabit this estuary are exposed to continued ship traffic, trawling fisheries, dredging operations, runoff from the Houston metro area, and salinity fluctuations. However, Galveston Bay is also a productive estuary and prey availability may outweigh facing these risks. The Galveston Bay Dolphin Research Program (GDRP) studies the dolphins that inhabit upper Galveston Bay and tackles questions on how they survive in their challenging environment.

The GDRP was formed in 2014 as a partnership between the Galveston Bay Foundation and the Environmental Institute of Houston at the University of Houston Clear Lake. We came together to develop a long-term research program to study and monitor the bottlenose dolphins (Tursiops truncatus) inhabiting Galveston Bay. Parallel with the research, we have developed outreach and education initiatives including a Field Assistant Volunteer Program that enables citizens to form an integral part of the field research crew.
