Ocean health and coastal sustainability are critical national and international issues, and marine scientists at UC Santa Cruz are leaders in addressing these challenges. UCSC has long been on the forefront of marine science research and education. With state-of-the-art facilities and internationally recognized faculty and researchers, the campus's Institute of Marine Sciences supports scientists in a wide range of disciplines. Their investigations range from microscopic plankton to massive blue whales, from the depths of the seafloor to the coastline, and from frigid polar waters to tropical coral reefs. This diversity reflects the many ways in which the oceans affect the global environment and the lives of people, in California and around the world. Through partnerships with state and federal agencies, environmental policy groups, and other organizations studying marine and coastal issues, UCSC has become a major hub for research, training, and outreach activities in marine science and conservation.
