From Sea to Pharmacy

The vastness of the ocean is only surpassed by the biodiversity within it; from familiar and unfamiliar mega-fauna, to every microbe and virus inhabiting every corner of the seas – from the deep freeze of the Antarctic to the scorching plumes of volcanic seafloor vents.

Paul Jensen describes how he and other researchers are tapping into the biodiversity of the world’s oceans as a relatively new resource for natural product drug discovery. Jensen is at the Center for Marine Biotechnology and Biomedicine at Scripps Institution of Oceanography, UC San Diego.

Understanding the Arctic Climate System

The Arctic is changing rapidly in response to global climate and economic activity and yet much of it remains unexplored with modern scientific techniques.

Jeff Bowman is a biological oceanographer who studies marine microbial communities. In this presentation at the Birch Aquarium at Scripps Institution of Oceanography he describes his group’s work in the Arctic as they seek to understand the ecological implications of changing sea ice conditions.

They are also preparing to participate in the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) Expedition, an unprecedented multi-national effort to study the high Arctic across a complete seasonal cycle.

California Seaweed

Kelp cutters once harvested tons of the nearshore kelp off the San Diego County coastline, producing additives for your ice cream, beer and pharmaceuticals.

And of course, anyone who has had a California Roll or a bowl of miso soup is familiar with the centuries-old use of Nori.

But now Scripps researchers are working to uncover other value from the ubiquitous red, green and brown algae that thrives in our waters, even exploring the use of seaweed to reduce methane produced by dairy cows – and perhaps even improving their health and productivity.

Join Scripps Oceanography’s Jennifer Smith and entrepreneur Brant Chlebowski as they tell the story of their collaboration on applied aquaculture research that has sparked the formation of the California Seaweed Company.

Eavesdropping on Whales

Since ancient seafarers first heard the strange calls of whales, humans have been fascinated by their meaning – from Flipper’s clicks and trills to the long serenades of Humpbacks. Inhabiting the dark ocean depths, whales use sound in many different ways – from feeding to navigating to finding friends and family.

Join postdoctoral scholar Goldie Phillips for a captivating look into how scientists use whale calls to study whale populations.

Feeling the Heat: The Biology of Ocean Warming

The effects of climate change on fauna and flora across the globe are more and more evident – the Pika has changed its range, and may disappear, sea stars have been visited by a withering collapse in population, insects from bark beetles to mosquitoes are inhabiting new territories, bringing disease to humans and destruction to forests. And close to home, the ocean temperature recently hit the highest temperature ever recorded.

As our changing climate provides a natural laboratory for examining how organisms evolve adaptations to environmental extremes, Scripps’ Oceanography’s Ron Burton asks: can evolution keep up with rapid climate change or are most species likely to go extinct as temperatures rise?

Ron shares about the cutting-edge genetic tools he uses to understand how populations of tidepool animals cope with rapid temperature changes and how evolution has shaped those responses across the geographic range of each species.
