Notes from the Field

threeopleReturning from JOIDES Resolution Expedition 379T, the science team has sought to study the oceanographic and hydrologic history of the northern margin of the Antarctic Circumpolar Current and the South American continent. The aim was to collect six 100 meters long sediment cores from ocean water depths of 829-3858 m near the Chilean margin (36-46°S) to understand variability of the Patagonian icefields. The next step in the research will be to evaluate rapid (100 to 1000 year) changes in ocean water chemistry, composition, and temperature that will not only help reconstruct climate over the last 200,000 years but also inform us about how Earth will respond to a warmer than present climate. Rutgers postdoc Samantha Bova and professor Yair Rosenthal served as co-chief scientists, and were joined by Hailey Riechelson (graduate student, Rutgers), Mark Yu (graduate student, Rutgers), Vincent Clementi (graduate student, Rutgers), Anya Hess (graduate student, Rutgers), Stanley Ko (graduate student, Rutgers), William Biggs (undergraduate student, Rutgers), and Jim Wright (professor, Rutgers).
