WHOI researchers Trevor Harrison (left) and Richard Sullivan push a Vibracore-driven sediment corer into the mud of Basin Bayou on the Florida panhandle, as guest graduate student Jess Rodysill (Brown University) observes. The three are working with WHOI geologist Jeff Donnelly and the Coastal Systems Group to analyze how coastal sediments accumulate over time, reflecting climate conditions. The Vibracore’s motor drives the core farther into the mud than people can push, allowing for a longer core and thus a longer history of sediment accumulation at the site.
