Coriolis II is a Canadian research vessel. She is homeported in Rimouski, Quebec. She is operated by a consortium of five institutions: (ISMER), the Université du Québec à Montréal (UQAM), McGill University, the (INRS-ETE) and the Maurice Lamontagne Institute (MLI-DFO). The vessel was constructed in 1990 by Versatile Pacific Shipyards of Esquimalt, British Columbia for the Canadian Coast Guard. Initially named CCGS John Jacobson, the vessel was deployed for search and rescue missions along Canada's coastlines. The Canadian Coast Guard took John Jacobson out of service in 1999 and sold the ship to her current owners in 2001.
