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.

Lakes Beneath Antarctic Ice: Deep, Dark and Mysterious

Where is one of the last places on earth you would expect to find a never-before known lake? Certainly, any of earth’s best-known deserts…the Sahara, Gobi, or Kalahari right?

Technically fitting the definition of a desert by standards of precipitation, Antarctica could also be on that well-known list of dry places.

But Antarctica has been imaged constantly for years across the entire visible and invisible spectrum and alas an unknown lake never popped up in any pictures until….who would think it…

In 2006, Helen Amanda Fricker was sitting at her desk studying new satellite data when she made a starting discovery – a set of active lakes that exist underneath the ice in Antarctica. Join Helen, a 25-year veteran of Antarctic ice sheet research, and learn about the discovery, exploration and drilling of these mysterious phenomena at the southern reaches of our planet.

From Stone Bowls to Unsuspected Superheroes

If rocks could talk – what could they tell us about the earth, history and maybe ourselves? Find out as collections manager Alex Hangsterfer and curator Richard Norris reveal the treasure trove of samples housed at Scripps. Hear some of the fascinating stories behind how these samples were collected and learn about the incredible variety of investigations that they enable – from plate tectonics to earthquakes to archaeology.

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.
