BNL INL Lateral Transport of Dissolved and Particulate TEIs at Ocean Margins K2-NW Pacific % Transmission Along Line W 228 Ra

Attributes of Line W as a GEOTRACES section Detailed hydrographic template within which to interpret geochemical profiles (proposed PO program to run until 2013). Frequency of cruises between Woods Hole and Bermuda facilitate re-occupation of stations along transect (Process studies? GEOTRACES Intercalibration Station?). Intersects with planned ORION/IOOS PIONEER program designed to characterize shelf-slope processes on NW Atlantic margin. Intersects major components of MOC (DWBC and Gulf Stream). Sharp, well-defined contrasts in water mass source/age/history. High productivity margin. Significant and distinct lateral particle fluxes in intermediate and bottom nepheloid layers. Prior and on-going sediment trap studies. Ideal for studies of elemental boundary scavenging. Potential western limb of an east-west transatlantic GEOTRACES section that interests major particle flux time- series stations.

PIONEER Array, Line W, and the Northeast Regional Coastal Ocean Observing System Line W Pioneer Array Deep Western Boundary Current

On-going and planned physical oceanographic measurements along Line W (J. Toole et al.) Moorings: Fixed instruments (moorings 2,4,6) -T/C sensors - Vector averaging current meters (VACMs) Moored Profilers (MMPs, moorings 1,3,5) - CTD - ADCP - Optical backscatter - Transmissometry (proposed) Hydrographic survey cruises: - CTD - Nutrients - Dissolved O2 - I CFCs/SF 6 - Optical backscatter + transmissometry

(Joyce et al., 2005) Composite mean property sections (1995 and 2006) along Line W. Average, net southward DWBC transport across Line W is estimated to be 16 Sv.
