Section 1 Research Goals: To understand through observations and to assess model ability to simulate, the global scale ocean circulation that is associated or possibly promotes climate change.
Section 2 Research Goals: Install and maintain three deep and bottom water focused moorings south of the South Orkney Islands in the Northwest Weddell Sea to provide a time series of the combined outflow (currents and temperature/salinity) of Antarctic Bottom Water drawn from various sites within the Weddell Sea. As the time series is compiled, it will be examined for indications of climate variability on sub-decadal time scales. A section of CTD/tracer stations is reoccupied during the service cruises as time and conditions permit. We rely on opportunistic scheduling of vessel time provided by a variety of sources, so timing of cruises for maintaining the moorings is approximate. Research goals remain flexible so we can take advantage of ship time opportunities as they arise.
