In January and February 2019, a major international scientific expedition explores one of the coldest, harshest and most remote locations in the world, the Weddell Sea. In November 2018, we spoke to one of the leading experts on the expedition, Professor Julian Dowdeswell, Director of the Scott Polar Research Institute and Professor of Physical Geography at the University of Cambridge. We discuss glaciers, ice-caps and this extraordinary journey that draws to a close soon.
