ITV News Science Correspondent Martin Stew was the only journalist on board the RRS Sir David Attenborough, deep within the Antarctic Circle. He joined Climate scientist Professor Mike Meredith who is studying how underwater tidal waves — triggered by collapses on that scale — alter the ocean and accelerate warming.

00:00The retreat in sea ice is linked to the warming of the ocean, and that's something that we
00:16know us humans are doing, so there's a direct signal there of our activity. The implications
00:22of this are climatic, in that it affects how reflective the surface of the planet is,
00:29so the planet's now absorbing more heat from the sun that it used to. It also removes
00:34a protective barrier from around Antarctica, and it can actually contribute to the destabilisation
00:40of the ice sheets. To stand there and see it directly in front
00:42of us was incredible. It was really unexpected. It really hit home that we're seeing some rapid
00:48changes to the region, and we don't know what the consequences of that will be.
00:52Thank you very much.
