UCSC’s Institute of Marine Sciences and Long Marine Lab

The Seymour Marine Discovery Center is a component of the Joseph M. Long Marine Laboratory, a research and education facility. Both the Center and the marine lab belong to UCSC’s Institute of Marine Sciences, which brings together scientists working in many different fields.

About the Institute of Marine Sciences

PISCO diversEstablished in 1972, the Institute supports research in marine biology, marine toxicology, marine geology and geophysics, ocean processes, paleoceanography, and coastal processes and hazards. Research subjects range from microscopic plankton to massive blue whales; from frigid Antarctic waters to tropical coral reefs; and from the depths of the seafloor to the coastal cliffs. This diversity reflects the many ways in which the oceans affect the global environment and the lives of people around the world. The Institute is composed of faculty, researchers, and staff who base their work from both the main UCSC campus and from the UCSC Coastal Science Campus.

About Long Marine Laboratory

Located adjacent to the Seymour Marine Discovery Center, Long Marine Laboratory is world renowned for innovative research in marine mammal physiology and ecology, marine invertebrate ecology, and marine toxicology. The research conducted at Long Marine Lab depends on a seawater system capable of delivering 1,000 gallons per minute of high-quality filtered seawater.


Researchers and staff at Long Marine Lab have developed specially designed tanks and equipment that are used for studying marine mammal diving physiology, bioacoustics, and cognition. Facilities for marine mammal work include five large pools and five smaller pools. The largest pool plunges to a depth of 30 ft. and has an underwater viewing lab with large windows.

Additional research facilities at Long Marine Lab include seawater laboratories for plankton and marine invertebrate research; radioisotope labs; environmental analytical labs, for extraction and precise measurements of trace levels of organic pollutants in water and tissue; a culture lab for marine invertebrate larvae and juveniles; a research SCUBA-diving, small-boat, and field-research support facility; and a station for remote sensing of surface currents.
