The oceanographic research and fisheries assessment vessel Arcticus, designed by JMS Naval Architects (JMS) of Mystic, Conn., completed her sea trials and was delivered to the U.S. Geological Survey's Great Lakes Science Center on Oct. 17. The Arcticus, replaces the Grayling and becomes the newest member of a 5-vessel fleet owned and operated by the Great Lakes Science Center in Ann Arbor, Mich. JMS completed the concept and contract design and provided all technical representation at the shipyard during construction.The vessel was constructed at Burger Boat Company of Manitowoc, Wisc.

The 78' Arcticus, is a steel, monohull research vessel capable of oceanographic research and fisheries assessment on the Great Lakes. The vessel is based at the Cheboygan Vessel Base. It is designed to conduct lake-wide bottom trawl surveys, acoustic surveys, gill net surveys, a variety of over-the-side science operations and will operate year round across three state boundaries, Canadian waters, and treaty waters of Lakes Huron, Michigan and Superior.
