Antarctica - Beneath the Surface - a podcast by Sky News

In the third and final part of Sky News' Antarctica series, Science correspondent Thomas Moore chats deglaciation, the temptation to mine the seabed for valuable commodities and the threat of plastics.

Thomas is on board the Royal Research Ship the James Clark Ross, making its way up the peninsula. Sunlight hits the seabed as the ice retreats and a team of scientists are up at 4am trawling a net on the bottom of the fjord.

Other teams are examining the quantity of plastic found in the Antarctic - extraordinary given the remote nature of the location.
