Oceanography (Video)

Oceanography (Video) is a feed of recorded talks given in public by researchers, engineers and artists working around Scripps Institution of Oceanography and Birch Aquarium. The unit is the lecture: a speaker, a room, slides on screen and, in some sessions, questions from the floor. It keeps the science close to the coastline it describes. The red tide talk begins with a photograph of bioluminescent waves breaking at Scripps Pier and asks the room for a show of hands. From there Drew Lucas builds a case like a detective story. A 1901 record notes that the bloom was patchy. A hypothesis credited to Dick Epley and colleagues holds that the cells swim up and down on a daily rhythm, and a ten-meter-deep tank on campus, with lights switched on and off, put that idea to the test. Internal waves enter the picture too, with plankton concentrated in their troughs. The payoff is the wire walker, a wave-powered vehicle that rides up and down the water column carrying samplers. A deep tank also appears in the SOARS talk, listed among the Hydraulics Laboratory's past facilities beside a glass channel and a stratified flow channel. That session marks sixty years of the building, built in 1964, and an engineer's account of it includes a party with a band on the mezzanine and a dry joke that every instrument must be ready tomorrow, cost almost nothing and collect data while you make your morning coffee. The machine itself is a wind tunnel set over a wave channel fed with seawater. Tereza Cavazos's Keeling lecture widens the frame to the U.S.-Mexico western border region. Climate, the talk insists, does not stop at the border. Atmospheric rivers, the North American monsoon, a shrinking Lake Mead and humid heat waves all appear, along with the speaker's account of setting aside astronomy for the atmosphere after a thesis on cloud seeding. Art sits right beside the science. In the Superradiance session, Memo Akten and Katie Peyton Hofstader perform part of a multiscreen work on view at Birch Aquarium, then explain how fluid and particle simulations steer a generative AI workflow run on a local gaming computer, closing on collaboration and the case that whoever voices the last idea does not own it. Beyond these, the title list ranges widely: whale song and whether it fits textbook ideas about animal singing, oxygen minimum zones and low-oxygen effects on invertebrate vision, a rare deep-sea footballfish washing ashore in Southern California, little blue penguins arriving at Birch Aquarium from Australia, sea urchin and sea slug embryos, plastic made from algae, and pink dye released where a river meets the ocean. Ocean observing programs appear under the 'Research for Resilience on a Changing Planet' banner, including The California Cooperative Oceanic Fisheries Investigations and the Southern California Coastal Ocean Observing System. The reward is hearing scientists lay out their evidence in order, from the old record to the new instrument, in their own words.
