An operation is underway in the Antartic to rescue 22 crew and 52 scientists trapped on an ice-bound research vessel since Christmas Eve.
The Shok-alskiy was trapped by thick sheets of ice about 1,500 nautical miles south of Hobart - the capital of the Australian state of Tasmania.
The vessel is being used by the Australasian Antarctic Expedition to follow the route explorer Douglas Mawson travelled a century ago. The rescue involves ferrying groups of passengers using a helicopter from a Chinese icebreaker.
Keelin spoke to Liz McCollum, a Wicklow vet, who has spent time aboard the Akademik Shok-alskiy.
