Damien first went to Antarctica in 1979 as a diving officer with the British Antarctic Survey. He completed a total of three Antarctic summers and two winters on bases at Signy Island in the South Orkney Islands, and at Grytviken, South Georgia, supporting the inshore marine biological program.
Damien was stranded on South Georgia during the Argentine occupation in the Falklands Conflict and was evacuated after British forces recaptured the island.
Damien has since worked as a commercial diver and marine archaeologist. He has taught in secondary schools and outdoor education for 17 years, and led expeditions of youth to Alaska and British Columbia. Damien began working on Antarctic tourist vessels in the 2004-2005 season and has spent time on ships visiting the Antarctic Peninsula, South Georgia and the Falkland Islands every year since.
He also visited the South Sandwich Islands in 2014. His first expedition cruise to the maritime Arctic was in 2007; since then, he has regularly worked on expedition voyages to Svalbard, Iceland, Greenland and the Canadian Arctic.
Damien has lived in Brittany, France, since 2006 and he now divides his time between marine archaeology and working on polar expedition ships.
