The CCGS Hudson is an offshore oceanographic and hydrographic survey vessel operated by the Canadian Coast Guard.
is Canada's oldest operational ocean research vessel. She was constructed in the early 1960s for the Canadian Oceanographic Service
, coinciding with the opening of the Bedford Institute of Oceanography
Formerly the CSS Hudson
, it was the largest vessel built at that time specifically designed for research purposes. For over four decades, the Hudson
has made significant contributions to knowledge about the oceans through hydrographic surveys and oceanographic research.
Particularly important was a 1970 voyage around both North and South America, the first time a ship made a voyage that transited the Americas. This research voyage established many benchmarks in marine observations, and demonstrated that navigation through the famous North-West Passage
was fundamentally dangerous because of uncharted undersea mountain peaks. This monumental voyage, in which over 100 scientists participated during various stages, was documented in the 1973 book "Voyage to the Edge of the World"
by Alan Edmonds (ISBN 0771030673).
The Government of Canada announced several new shipbuilding projects for the Canadian Coast Guard in 2007, including a replacement for CCGS Hudson
to be delivered by 2014, giving her over 50 years of operational service to Canada.
