Science Objectives

Line W is one component of a long-term climate observing system that is positioned to quantify variability in the deep limb of the Atlantic meridional overturning circulation (MOC). The field program has been operating since 2004 and includes a 6-element array of instruments situated down the continental slope south of Woods Hole and is augmented by yearly occupations of a hydrographic section along this line extending toward Bermuda.  The moored array, which utilizes McLane profilers, current meters plus T/C sensors, is designed to quantify changes in DWBC / Gulf Stream water properties, stratification (potential vorticity) and transport. Shipboard observations using CTD, LADCP and discrete sampling for salinity, oxygen, CFCs, SF6 and I129 measure the water column properties at high spatial resolution to help verify that the array resolves interannual signals.  These measurements are key to clarifying the deep ocean response to variability in high-latitude air-sea exchanges and, ultimately, the ocean's role in global climate variability through changes in its transport of heat and freshwater.
