First up this week, a ship that flips for science. Sean Cummings, a freelance science journalist, joins host Sarah Crespi to talk about the resurrection of the Floating Instrument Platform (R/V FLIP), a research vessel built by the U.S. Navy in the 1960s and retired in 2023. FLIP is famous for turning vertically 90° so the bulk of the long ship is underwater, stabilizing it for data gathering. Additional audio from Scripps Institution of Oceanography. Watch FLIP flipping here.
