 Line W has three moorings with profilers that travel up and down cables taking measurements of water salinity, temperature, and velocity. They are interspersed with moorings with sensors distributed along cables (including the GUSTO mooring). The moorings monitor the southward, cold Deep Western Boundary Current and the northward, warm, surface Gulf Stream, which act like an artery and vein in the North Atlantic Ocean circulation system.
