Damien first came to Antarctica in 1979 with the British Antarctic Survey as a diving officer, and has experienced three Antarctic summers and two winters on bases at Signy Island, South Orkneys; and at Grytviken, South Georgia, supporting the inshore marine biological programme. He was stranded on South Georgia during the Argentine occupation in the Falklands Conflict and was evacuated after British forces recaptured the Island.
He has subsequently worked as a commercial diver, a marine archaeologist and taught in secondary schools and outdoor education for seventeen years. He has been a leader on expeditions taking young people to Alaska and British Columbia. Damien began working on Antarctic Tourist vessels during the 2004-5 season. His first trip to the Maritime Arctic was in 2007, since when he has regularly worked on trips to Svalbard, Iceland and Greenland, and traversed the North West Passage. Since 2006 he has lived in Brittany, France, where he now divides his time between Marine Archaeology and working on polar expedition ships.
