THIS IS A JOB FOR THE VIBRACORER—Scientists usually use large corers to penetrate seafloor sediments and extract samples used to decipher ocean changes far back in Earth’s history. But a particularly hard-packed area off the New Jersey coast required something bigger—and tougher. Last summer, University of Texas geophysicist Jamie Austin and colleagues traveled on the research vessel Knorr with a vibracorer, a tool designed to shimmy into even the toughest seafloor sediments. “It essentially functions like a pile driver,” Austin said, adding that any other corer used in that location “would just bounce right off this tough sediment.” Austin graduated in 1979 with his doctorate degree from the MIT-WHOI Joint Program. For 20 years, he has been traveling to the New Jersey shelf to learn about past sea level changes in this region. “We now are beginning to understand how the geology of the shelf responds as sea level falls and then rises,” Austin said. The research, he added, is “very relevant to preparing for sea level rise to come, as a response to global warming.”
