Elephant Seals Gather Data Guest: Louise Biddle, researcher at the Department of Marine Sciences at the University of Gothenburg, Sweden Understanding how ocean currents work is key to understanding climate. While we have autonomous gliders that send back data from the watery depths, but areas under the deep Antarctic ice are inaccessible by autonomous glider. So, scientists used data gathered from elephant seal dives to study how the ocean moves under deep ice. The Sunken Bridge to England Guest: Vince Gaffney, Anniversary Chair in Landscape Archaeology and Professor at the University of Bradford Doggerland is an ancient sunken land that connected England to the rest of Europe. Its story has implications for how we can deal with rising coastlines.
