Oceanic Manta Rays (Manta birostris) are increasingly caught in targeted fisheries for their gill rakers, fueled by demand as a pseudo-remedy in traditional Chinese medicine. Given extremely low reproductive rates, even small artesanal fisheries and by-catch will have significant impacts on manta populations, while large-scale targeted fisheries may lead to population decline and perhaps local extinction. Understanding the basic ecology and population dynamics of the species is a prerequisite to developing effective conservation and management strategies for the species. Semmens Lab PhD student Josh Stewart is investigating the population structure and spatial ecology of oceanic manta rays in the Indo-Pacific using a diversity of techniques to identify space use, migratory corridors, regional sub-populations and connectivity between oceanic manta hotspots and aggregations.

Over the last 30 years predictions of climate change as a threat to individuals, societies and nations have changed from possibilities to realities. Ethical issues associated with individuals, companies, nations which cause climate change, who might benefit from it, and who will suffer from the impacts have been part of the discussion from the beginning. How has thinking about the ethics of climate change evolved during that time and how does this relate to the ethics of extreme mitigation efforts like climate engineering? Margaret Leinen, UC San Diego Vice Chancellor for Marine Sciences, Director of Scripps Institution of Oceanography, and Dean of the School of Marine Sciences discusses what can be done, what is being done, and the ethical implications of deploying solutions.

Long term, sustained ocean observations provide scientists with much needed insight into natural and human induced changes in the world ocean. Join NOAA’s Southwest Fisheries Science Center Director Francisco Werner as he provides a broad perspective on ocean observing and its scientific value and application, as well as a close up look at the important monitoring effort in our own coastal ocean, the California Cooperative Oceanic Fisheries Investigations.

In the fourth installment of the Future Thought Leaders series, nationally prominent chefs, fishermen, academics, and activists call on consumers to choose local species of fish when possible to protect the long-term vitality of harvested seafood and the well-being of the oceans. This series was presented by the Berry Good Food Foundation. Series: "Climate Solutions " [Public Affairs] [Science] [Agriculture] [Show ID: 30713]

Scripps Oceanography welcomes America’s newest oceanographic research vessel: R/V Sally Ride. The ship features the most advanced oceanographic research tools available, and is named in honor of America’s first woman in space, science advocate, and UC San Diego Professor, Sally Ride. Gain an insider's look at what it takes to design, build, and run one of the most important tools modern day explorers will use to understand and protect the planet. Series: "Jeffrey B.

David Valentine highlights recent ocean exploration activities undertaken by UCSB faculty, staff and students. Many scientific discoveries are enabled through the combined use of manned submarines, remote controlled, and fully autonomous underwater vehicles. The discoveries themselves range from bizarre viruses to waste dump sites to geologic features and highlight the power of exploration for discovery. Series: "GRIT Talks" [Science] [Show ID: 31480]

Scripps Institution of Oceanography’s Jennifer Hofmeister gives a lively account of why and how she is working to understand the behavior of octopuses in order to save California’s endangered white abalone, which faces extinction when the last adult generations die out within the next decade.
