Join John Chapman, a Courtesy Professor of Fisheries, Department of Fisheries and Wildlife at Oregon State University (OSU), on Thursday, July 28 at 3:30 p.m. to learn about his research on the invasion ecology of marine hull-fouling species found on the Research Vessel Oceanus. This lecture is part of the Hatfield Marine Science Center's (HMSC) weekly research seminar series.
The Oceanus was the primary research vessel for OSU until it was retired in November of 2021. The ship was part of the National Science Foundation’s U.S. Academic Fleet and served the Woods Hole Oceanographic Institute from 1975 until it was transferred to OSU in 2012. Now, the ship is docked near HMSC and can be viewed by the public.
About the talk: "The R/V Oceanus completed a 9,789 km, 28-day passage from Woods Hole, Massachusetts, in the Atlantic Ocean, through the Panama Canal to Yaquina Bay, Oregon, in the Pacific Ocean on 21 February 2012 and came to us with a story. The Oceanus had previously operated in the Mediterranean Sea and Atlantic Ocean (including the Caribbean Sea). We document the sequential acquisition of the barnacles Balanus trigonus and Amphibalanus venustus and the oyster Ostrea equestris on the Oceanus on its high and low latitude transoceanic, intra-oceanic, and interoceanic travels before she was surveyed in Yaquina Bay. The close correspondence between hull fouling accumulations and the detailed two-year Oceanus working history reveals B. trigonus settlement occurred in every tropical port visited by the Oceanus, that some populations survived through two of three Woods Hole winters, and that some of these populations passed through the freshwater Panama Canal. These results indicate that marine hull-fouling species are continuously transported globally between most ports of call by most ship passages."
These talks are delivered in a hybrid fashion. The event is free, and all are welcome to attend in person in the auditorium of the Gladys Valley Marine Studies Building at the HMSC (2030 S.E. Marine Science Dr) or can register here to attend remotely via Zoom.
