Sharks have long fascinated the public. While popular media has often promoted images of large, aggressive predators, most sharks are not dangerous to people and moreover are a vital part of many healthy ocean ecosystems. Join Scripps Institution of Oceanography's Dovi Kacev for an illuminating journey into the Southern California Bight to learn about the sharks that make our offshore region their home.

Shark Geek: A Window into Shark Ecology in the Southern California Bight

The ocean plays a major role in regulating Earth’s temperature through exchange of chemicals and microbes with the atmosphere. When waves break, ocean-derived biological species including viruses and bacteria are transferred into the atmosphere. These species can ultimately form clouds, altering precipitation and climate. Highlights will be presented of novel experiments being conducted in a unique ocean-atmosphere simulator developed by the National Science Foundation (NSF) Center for Aerosol Impacts on Chemistry of the Environment (CAICE). Kimberly Prather, Professor of Climate, Atmospheric Science, and Physical Oceanography at UC San Diego will focus on recent CAICE studies aimed at advancing our understanding of how the oceans influence human and planetary health. New insights will be discussed as well as future studies designed to unravel human versus microbial impacts on the changing Earth’s system. Series: "Exploring Ethics" [Show ID: 35000]

How Do We Know Humans are Impacting the Health of Our Planet? - Exploring Ethics

Scientific drill ships allow scientists access to some of Earth's most challenging environments, collecting data and samples of sediment, rock, fluids and living organisms from below the seafloor. Join Scripps paleontologist Dick Norris to learn about the long running international collaboration in scientific ocean drilling that has transformed human understanding of our planet.

Exploring the Earth Under the Sea: Over 50 Years of Scientific Seafloor Drilling

Over millions of years of evolution, organisms on earth have developed and perfected complex adaptations that allow them to survive and eventually thrive under specific environmental conditions. Dimitri Deheyn unveils how his laboratory is working to understand and replicate these highly refined biological properties for development of sustainable and economically valuable technologies.

Biomimicry: Innovating Using Nature’s Toolbox

Ours is a water planet. Technology is shaping our uses, both as foe and ally. It has made humans the dominant predator and provides us food, gives us half the oxygen we breathe and created many maritime jobs. But technology has also raised CO2 levels, caused acidic oceans, threatened ocean biodiversity and created grand climate challenges. UCSB marine biologist Doug McCauley describes technology to promote ocean health and provide a balance. Series: "GRIT Talks" [Show ID: 35175]

Technology: Friend or Foe for the Future of our Oceans

Extremely sensitive to shifts in temperature, the ochre sea star is considered a “keystone species” for monitoring the effect of changing air and ocean temperatures on California’s marine life. Eric Sanford of the UC Davis Bodega Bay Marine Lab puts these beautiful creatures to the test, using their appetite for mussels as the yardstick. Series: "UCTV Prime cuts" [Science] [Show ID: 24211]

Marine Science Looks to the (Sea) Stars - UCTV Prime Cuts

Nature has provided the inspiration for many of today’s most important medicines, yet the need for new drugs to treat diseases such as cancer and antibiotic resistant bacterial infection remains high. Paul Jensen describes how he and other researchers are tapping into the world’s oceans – home to a majority of its biodiversity – as a relatively new resource for natural product drug discovery.

Marine Natural Products: From Sea to Pharmacy

Marine biologist Jennifer Smith talks about the properties and history of the superfood seaweed. Series: "Jeffrey B. Graham Perspectives on Ocean Science Lecture Series" [Science] [Show ID: 35070]

Seaweed as a Superfood

The Arctic is changing rapidly in response to changes in global climate and economic activity and yet much of it remains unexplored with modern scientific techniques. Jeff Bowman describes his group's work in the Arctic as they seek to understand the ecological implications of changing sea ice conditions, and prepare to participate in the MOSAiC expedition; an unprecedented multi-national effort to study the high Arctic across a complete seasonal cycle.

Modern Oceanography and the Changing Arctic Ocean

Collapsing ice shelves and calving of large icebergs in Greenland and Antarctica have recently become major drivers of sea level rise. The rapidity of these changes has come as a surprise, revealing major gaps in our understanding of how ice sheets respond to a changing climate. To a large extent, these gaps are due to the lack of measurements from the marine edge of glaciers - the Achilles' heel of glaciers. For over a decade, since the glaciers in Greenland began their retreat, Fiammetta Straneo and her group at Scripps Institution of Oceanography have been probing the edge of massive calving glaciers in iceberg-choked fjords in Greenland using helicopters, icebreakers, fishing vessels, and autonomous vehicles. The understanding gained through these measurements is being used in models aimed at improving sea-level rise predictions. Series: "Jeffrey B.

Earths climate is a complex system with global scale interactions spanning the tropics to the poles. Join emeritus Professor and past Scripps Director Charles Kennel as he reveals the potential of arctic sea ice loss to influence the intensity of climate events such as El Nino, and raises the possibility that more changes in weather patterns and extreme events are to come.

Food Feed and Climate Change – Emerging Opportunities for Shore Based Seaweed Aquaculture

Sooner or later, the food requirements of nine billion people with increasing appetites for seafood must be addressed. Although aquaculture may supply the majority of the global ‘seafood’, most aquaculture is fed meal from wild caught fish, such as sardine and anchovy. To estimate the distributions and abundance of these and other small fish off the west coast, NOAA Southwest Fisheries Science Center routinely conducts “acoustic-trawl” surveys. David Demer will briefly describe the vessels, instrumentation and methods that are used to conduct these surveys, and provide a virtual tour of the world-class facilities in La Jolla that are used to develop the next generation of autonomous, ocean-sampling technologies. Join us to learn more about this exciting technology and be part of a discussion about possible ethical challenges. Series: "Exploring Ethics" [Humanities] [Science] [Agriculture] [Show ID: 34378]
