    The Role of the Canadian Hydrographic Service and the Canadian Coast Guard in the Discovery of the HMS Erebus
    The discovery of HMS Erebus, one of Sir John Franklin's two lost ships, is a significant occasion for Fisheries and Oceans Canada as it showcases the important work of the Canadian Hydrographic Service (CHS) and the Canadian Coast Guard (CCG). Along with public and private partners, the Canadian Hydrographic Service and the Canadian Coast Guard joined the Victoria Strait Project with a number of common objectives such as mapping Canada's Arctic seabed, conducting arctic research and searching for the lost ships of Sir John Franklin's 1845 voyage to find the Northwest Passage. The discovery of one of the lost ships provides us with an important opportunity to recognize the work of both the Canadian Hydrographic Service and the Canadian Coast Guard during the Victoria Strait Project and, more importantly, their work in improving navigation safety as well as contributing to scientific advancements.
