In 1998 , '' Matthew '' was among the Canadian Coast Guard vessels assigned to the search for Swissair Flight 111 , mapping the wreckage off the coast of Nova Scotia . The ship participated in the mapping of Placentia Bay , Newfoundland in co-operation with Natural Resources Canada and the Canadian Hydrographic Service in April 2004 . The vessel was used for mapping the coastal sea floor and harbour entries , which allowed smaller craft to keep closer the shoreline rather than sail out in the heavier seas . The vessel spent much of its time updating nautical charts that had not been reviewed since the time of Captain James Cook . '' Matthew '' was also detailed to investigate sinkholes in Bras d’Or Lake of Cape Breton Island . '' Matthew '' was decommissioned in 2016 , renamed '' 2015-03 '' and was put up for auction . The former Coast Guard vessel was taken out of service due to a change in the way coastal mapping was to be performed by the government , with a switch towards " coastal parties , ship-based surveys and airborne hydrography . " The ship was put up for auction five times , receiving no bids
