Marine Science

Advancing knowledge to support the world’s oceans and coasts, critical ecosystems for life on Earth.

Researching Science and the Sea

Ocean Life and Interactions

Based in Port Aransas on the Texas Gulf Coast, our marine scientists and their teams of graduate students, undergraduate researchers and staff colleagues leverage a range of resources to better understand sea and estuary life and conditions over time. Experts in the Department of Marine Science leverage the resources of UT’s Mission-Aransas National Estuarine Research Reserve and its 186,189 acres that make it among the largest U.S. research stations of its kind.

Study & Learn

Marine and freshwater science, an option within the biology degree for undergraduates, involves a blend of study at the Austin campus and at UT Austin’s Marine Science Institute (MSI) in Port Aransas. Students take some credits in residence at MSI through Semester by the Sea or May term options. An undergraduate degree in biology allows students to specialize if they choose in marine and freshwater science. A certificate allows for further skill-building and study. Graduate study in marine science is also available with residence in Port Aransas.
