Science Objectives | |
| This cruise is privately funded by the same foundation that funded WHOI to get started on developing the new long coring system. The idea is to promote interdisciplinary studies by collecting sediment cores from locations that are well instrumented for modern observations. WHOI's line W array, south of the Cape and Islands is one such region. There are multiple moorings measuring physical and chemical properties of the ocean, and there are sediment traps that allow us to calculate fluxes of sediment to the seafloor. Another such location is in Jordan Basin, northeast Gulf of Maine, where NOAA has an instrumented buoy and where there is a long history of sediment trapping and plankton towing. Remarkably, there are no studies of the paleoclimate using sediment cores from these regions. In deep water (south of WH) surveys will be conducted by 3.5 kHz sonar, and in the Gulf of Maine Liviu Giosan will survey with his towed chirp sonar. Our Jordan Basin site is well-known, but south of WH the continental margin is dominated by down-slope processes and finding good core sites will be a challenge. We may work farther to the east in the NE Seamount region, where seamounts may affect the prevailing deep flow and cause constructional sedimentary deposits. Each site will be sampled with a multicorer, a gravity corer, and a large diameter piston corer. In addition, we will deploy a sediment trap at Jordan Basin. | |
