Perspectives on Ocean Science

Exploring the undersea world has always presented challenges in terms of cost and accessibility. However, recent advances in ocean observing technology are allowing researchers to explore heretofore unexplored worlds at reasonable cost. Join oceanographer Jules Jaffe as he describes his career as an ocean explorer and technology innovator. Learn how new, cost effective instruments and platforms present unprecedented opportunities for students of all ages to engage in designing, building and experimenting with ocean observing technologies with examples from underwater robots and underwater microscopes.

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.

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.

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.

The ALERTWildfire camera network across California provides rapid confirmation of emergency wildfire 911 calls, situational awareness, and in the worst-case scenarios real-time data to help sequence evacuations. Join Neal Driscoll to learn how the great state of California is using technology to help firefighters and improve public preparedness during wildfire disasters. Series: "Jeffrey B.

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.

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.

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.
