Description

The scientific objective of this cruise is to collect settling and suspended particles at 3 locations on the northwest Atlantic margin to determine carbon transport from the shelf/slope to the deep basin, coupled with physical oceanographic data from moorings at station W. Sampling activities during the cruise will include: deployment and recovery of bottom-tethered sediment trap moorings; hydrographic sampling of bottom and intermediate-depth nepheloid layers via CTD with transmissometer and turbidity sensors and 24x10Liter Niskin rosette; water sampling via McLane in situ large volume pumping systems; use of a McLane Moored Profiler (MMP information) and multicoring of seafloor surface sediments.

The cruise will also sample at the Line W station location in the North Atlantic Deep Western Boundary Current and Gulf Stream at 39 degrees North. Line W is a sustained measurement program. The researchers plan to recover 3 moorings and redeploy 1 mooring at station W.

Cruise information and original data are available from the NSF R2R data catalog.
