Science Objectives | |
| The overall goal of the project is to examine the transport and export of particulate organic carbon (POC) over the NW Atlantic Ocean margin. Specific objectives are to examine the role of the Deep Western Boundary Current in along-margin transport of POC. It is hypothesized that along- and across-margin transport of POC is important for supply of organic carbon to deep-ocean sediments. Geochemical investigations of organic matter entrained in bottom and intermediate depth suspended particle (nepheloid) layers as well as sinking particles are planned as well as hydrographic surveys in order to place findings within the context of regional physical oceanography. Hydrographic surveys and sampling will occur along 3 across-margin transects in each case extending from the shelf-break to ~ 5000 m water depth (off Nova Scotia, off Cape Cod, and off Cape Hatteras). We are planning a series of 3 across-margin transects designed to capture the sources and movement of particulate matter. We will be mostly doing CTD hydrocasts and large-volume (up to 1000L) in-situ filtration with McLane submersible pumps. We will also be deploying 2 sediment trap moorings and we may do some sediment coring (multicorer). We hope to obtain high vertical and spatial resolution filter samples for detailed analysis of particle abundance and characteristics within intermediate-depth and bottom nepheloid layers. | |
