Science objectives

• Monitoring of the DWBC for water mass and transport signatures related to changes in the strengths and regions of high latitude water mass formation in the North Atlantic for the ultimate purpose of assessing rapid climate change.
• Serving as a western boundary endpoint of a subtropical meridional overturning circulation (MOC)/heat flux monitoring system designed to measure the interior dynamic height difference across the entire Atlantic basin and its associated baroclinic heat transport.
• Monitoring the intensity of the Antilles Current as an index (together with the Florida Current) of interannual variability in the strength of the subtropical gyre.

 

Science Activities

Leg 1:  Mooring recovery and redeployment of United Kingdom Rapid Array tpo monitor the Meridional Overturning Circulation.  Recovery and redeployment of NOAA's inverted echosounder array (part of the Western Boundary Time Series Project).
Leg 2: Hydrographic sections along the continental slope west of Abaco Island Grand Bahamas across the Deep Western Boundary Current and three sections in the Northwest Providence Channel and the Florida Straits.
