Science objectives
This is a three-year project to conduct paleo-ocean and paleoclimate studies of deep ocean sediments from high deposition rate sites in the western subtropical North Atlantic. In the first year, research will be conducted on existing samples from Laurentian Fan and new samples will be collected during a three week surveying and coring cruise to locations between Newfoundland and the Mid Atlantic Ridge (MAR). These sites include the Tail of the Grand Bank, Corner Rise, the west flank of the MAR, and small plateaus and basins near the crest of the MAR. Each location will be sampled with a multicorer, a gravity corer, and a large diameter piston corer. The underlying theme of this research is to link radiocarbon ventilation ages in the deep ocean, as measured by paired 14C analysis of benthic and planktonic foraminifera, with surface ocean conditions on different spatial and temporal scales.Science Activities
