Oceanography (Audio)

Glowing blue waves and unusual ocean conditions wowed the world during Southern California's recent history-making red tide event. Join Scripps Institution of Oceanography bioluminescence expert Michael Latz, Ph.D. and dive into the world of living light, get an insider's look at the most recent red tide event, and learn why scientists still have so many questions about this natural phenomenon.

In general, animal song is thought to have several specific characteristics including being restricted to males, having a territorial purpose, and being used to attract a mate. Join marine acoustics expert John Hildebrand to learn how the singing characteristics in some whale species challenges this generalization and how long term trends in whale song still present a mystery to scientists.

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.

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.

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.

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" [Science] [Show ID: 35175]

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]

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.
