| Objectives | R/V Atlantis cruise number 17 contributed to a joint Woods Hole Oceanographic Institution and Lamont Doherty Earth Observatory research program funded by the U.S. National Science Foundation that is investigating the characteristics, causes and consequences of interannual variations in the Northwest Atlantic's Deep Western Boundary Current (DWBC). The study is documenting temperature, salinity, tracer, and velocity variations of the DWBC by maintaining a 6-element moored array spanning the continental slope southeast of Woods Hole, and repeatedly occupying a hydrographic section along this line. A companion research program by U.K. investigators from the Proudman Oceanographic Laboratory is sampling bottom pressure variability (their instruments are called Bottom Pressure Recorders - BPRs) at several of our mooring sites (plus a shallower site) and along an additional measurement line to the north. Cruise AT17 was designed to service the moored array (recover and redeploy the 6 moorings) and to occupy the hydrographic section along the array and extending southwest to 66°W. In addition, time permitting, we agreed to deploy an ocean glider, launch an Argo float, do test lowerings on a cable of a new BPR sensor and perform test deployments of the High Resolution Profiler instrument for WHOI colleagues. |
