Oceanography (Audio)

Climate change is fundamentally altering marine environments worldwide. But what does this mean for the creatures that call the ocean home? Join Martin Tresguerres, Ph.D., as he delves into the work of the Allen Discovery Center for Neurobiology in Changing Environments (ADC-NiCE), where researchers are working towards answering this question. Through a combination of neurobiology, physiology and environmental science, ADC-NiCE investigates how climate change affects the nervous systems and behavior of marine animals — ultimately guiding policy, conservation strategies and restoration efforts.

If you love seafood, you’re not alone — but every bite comes from a complex and fragile marine ecosystem. To keep our ocean ecosystems thriving and our seafood resources abundant, we need a deeper scientific understanding of how they function. Colleen Petrik, a professor of oceanography at UC San Diego's Scripps Institution of Oceanography, talks about her work studying the changing ecosystem of the ocean from fishing to coastal development.

How do most organisms in the natural world communicate? It's through the language of chemistry. Scripps Institution of Oceanography marine biologists Bradley Moore and Natalie Grayson explore how ocean life uses molecules as a language. Examples include a pigment that lets squid and octopus change color for camouflage, a coral and its microbial partners that produce biologically active compounds, and a chemical now in phase three human clinical trials to treat glioblastoma, an aggressive cancer of the brain. Their research has applications for new materials in biotech, and improving the food supply and human health. Series: "Jeffrey B.

For many people, a personal connection to the ocean ties into bigger issues like conservation and climate change. As the biodiversity of marine life along the coast at La Jolla Shores has declined, divers and researchers discuss why simply knowing about environmental problems isn’t enough. They emphasize the importance of conservation psychology, storytelling, and inspiration to encourage action. This video was created by graduate students in Marine Biodiversity & Conservation at Scripps Institution of Oceanography, UC San Diego. [Science] [Show ID: 41072]

The land we now call Scripps Oceanography has been home to the Kumeyaay people for thousands of years. A history of encroachment, colonization and displacement from coastal lands has challenged Kumeyaay ocean traditions and practices. Today, Kumeyaay-Iipay-Tipay people are actively revitalizing Indigenous ocean culture. As part of Perspectives on Ocean Science Lecture Series, Stan Rodriguez and Priscilla Ortiz Sawah of the Iipay Nation of Santa Ysabel, and Andrew James Pittman of the Los Coyotes Band and Cupeño Indians, talk about the history of the Kumeyaay culture in the region. Through community efforts, they are rebuilding traditional ha kwaiyo (tule boats), harvesting ha shupill (grunion) and teaching language about the ocean (ha silowik). These intergenerational practices embody Indigenous resilience, resistance and revival — nurturing and evolving Indigenous ocean knowledge, culture and traditions. Series: "Jeffrey B.
