CCGS Hudson - Canada's most famous scientific ship. Launched in 1962, commissioned in 1964 and still making important scientific contributions after 47 years on the high seas. In the 1960s, evidence of continental drift was increasing throughout the world. This body of knowledge was greatly enhanced by the detailed geophysical surveys of the Mid-Atlantic Ridge carried out during five Hudson cruises. Later in the decade, the most detailed oceanographic wintertime survey ever attempted of the Labrador Sea was completed from Hudson. This was the first of many studies in this area aimed at understanding the Labrador Current and the deep mixing which occurs during severe winters. In the following year, 1967, the first oceanographic winter survey of Denmark Strait, including the first current meter measurements, was completed from Hudson.
