Neurobiology in a Changing Ocean with Martin Tresguerres Aug 28, 2026

Show notes

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.

Science and Seafood: Understanding and Protecting a Precious Natural Resource Feb 23, 2026

Show notes

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.

Harnessing Nature's Innovations from the Sea Jan 05, 2026

Show notes

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.

Lessons from La Jolla Shores Sep 29, 2025

Show notes

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]

Kumeyaay Ha Kwaiyo - Indigenous Ocean Culture: A Renaissance Jul 23, 2025

Show notes

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.

Seas the Day: A New Narrative for the Ocean Jul 15, 2025

Show notes

It's time for a new narrative for the ocean, one that reflects current scientific knowledge and acknowledges innovative new partnerships and solutions that center the ocean in our future. In this program, Jane Lubchenco, Professor of Marine Biology at Oregon State University and with expertise in the ocean, climate change, and interactions between the environment and human well-being, talks about the two current dominant narratives for the ocean are anchored in the past. The older one considers the ocean to be so vast, bountiful, and resilient that it is simply too big to fail. This first narrative drives pollution and over-exploitation of resources. A second, more recent narrative is that the ocean is now so depleted, polluted, and disrupted, and the drivers of those outcomes are so powerful and complex, that the ocean is simply too big to fix. A third, new narrative is emerging, based on scientific findings, existing solutions, and innovative partnerships and policies. This new narrative acknowledges that the ocean is central to a safe, clean, healthy, just, and prosperous future. This new narrative tells us that the ocean is neither too big to fail, nor is it too big to fix. But it is too important and too central to our future to ignore.

Walking the Pier: Women in Scripps Plankton Research Jun 15, 2025

Show notes

The Birch Aquarium celebrates the incredible contributions of women in the rich history of marine plankton research at Scripps. Judit Hersko performs part of her innovative series of visual narratives, "Pages from the Book of the Unknown Explorer," transporting you to Scripps’ early days through a cleverly imagined correspondence between Dr. Easter Cupp, Scripps' first female Ph.D. graduate, and a fictitious female explorer inspired by Hersko's research and field experience in Antarctica. Melissa Carter takes us on a journey through nearly a century of observations from Scripps Pier, bringing us to the present day. She provides an insider’s look at emerging research and observational technologies used on the pier and explores how these innovations drive new, groundbreaking discoveries in marine plankton research.

Superradiance: Embodying Earth Jun 01, 2025

Show notes

Superradiance: Embodying Earth is a multiscreen video and sound installation by artists Memo Akten and Katie Peyton Hofstader that serves as a centerpiece of Embodied Pacific: Oceans Unseen. Learn how collaboration-inspired immersive displays engage us and shape our understanding and appreciation of the ocean’s unseen mysteries. The Birch Aquarium hosts this Jeffery B. Graham Perspectives on Ocean Science Lecture Series for a conversation with the artists as they describe how they use art to engage us in science, evoking a visceral and intimate connection to our living planet!

From the Laboratory to the Ocean: The Scripps Ocean-Atmosphere Research Simulator (SOARS) Apr 07, 2025

Show notes

At 120-feet long, and holding 36,000 gallons of water, the Scripps Ocean-Atmosphere Research Simulator (SOARS) is a unique facility at Scripps Institution of Oceanography. SOARS is much more than a wave generator, it allows scientists to replicate ocean conditions, including wind, waves, water chemistry, temperature, and light, in a controlled environment. By simulating ocean environments in a controlled laboratory setting, researchers are able to study ocean-atmosphere interactions, climate change, and more. Scripps Institution of Oceanography Lead Engineer Douglas Alden and Researcher Grant Deane give an inside look on how scientists are able to study how human activities are changing the ocean and atmosphere, and how these changes impact global climate and other areas like human health and marine life protection.

Ebb and Flow: Giant Kelp Forests through Art Science and the Archive Mar 24, 2025

Show notes

This film explores the dynamic fusion of science, art and historic collections, set against the stunning backdrop of La Jolla’s hidden underwater world of giant kelp forests. Five artists talks about their unique perspectives captured in the exhibition "Ebb and Flow: Giant Kelp Forests through Art, Science and the Archive," at UC San Diego's Geisel Library. Produced by Mary Ann Beyster, with assistance from filmmaker Eladio Arvelo, the film reveals the profound beauty, healing power and global significance of the vital kelp habitat.
