In the 1980s and 1990s, "Hudson" took part in large surveys that were part of international programs such as the Joint Global Ocean Fluxes Study and World Ocean Circulation Experiment. In 1980, "Hudson" circumnavigated North America. "Hudson" contributed significantly during recovery operations during the aftermath of the semi-submersible mobile offshore drilling unit that sank in Eastern Canadian waters on 15 February 1982. "Hudson" saved all 24 crew members of MV "Skipper 1" in the North Atlantic on 29 April 1987. On 28 April 1988, an explosion was spotted by the crew over the horizon. When "Hudson" arrived on scene, they found the tanker "Athenian Venture" on fire and in two pieces. "Hudson" recovered only one body from among the wreckage.
