In 1975, the newly constructed hull of R/V Oceanus first entered the water at Peterson Builders shipyard in Sturgeon Bay, Wisconsin. During its 36-year career, Oceanus criss-crossed the Atlantic helping scientists better understand the processes that shape all of Earth’s oceans and enabling engineers to design better, more capable instruments that peer deep beneath the surface. Yesterday, Oceanus completed its final mission and today WHOI salutes this proud veteran of oceanographic research and all those who made its work possible. Job well done, Oceanus.
