PurposeResearch
ObjectivesThe RAPID/MOCHA program is a joint research effort between the National Oceanography Centre (Southampton, U.K.), the University of Miami's Rosenstiel School of Marine and Atmospheric Science (RSMAS), and NOAA's Atlantic Oceanographic and Meteorological Laboratory (AOML). The objective of this program is to establish a pre-operational prototype system to continuously observe the strength and structure of the Atlantic meridional overturning circulation across the basin at 26º N. The U.K. program is referred to as "RAPID-MOC" and is a part of the U.K. Rapid Climate Change Program (RAPID) funded by the National Environmental Research Council (NERC). The U.S. program is referred to as "MOCHA" (Meridional Overturning Circulation and Heat-flux Array) and is funded by the National Science Foundation (NSF). NOAA provides significant support for the overall effort through its Western Boundary Time Series Program.

The purpose of cruise SJ-14-06 was fourfold:
1)to service 4 mooring sites that constitute part of the "western boundary array" of the RAPID/MOCHA transbasin moored array
2)to conduct hydrographic (CTDO2) and direct current profiling (lowered-ADCP, "LADCP") stations along the 26.5 º N mooring section off Abaco, Bahamas; and along sections in the Northwest Providence Channel and Florida Current at 27º N,
3)to service 3 inverted echo sounder (IES) sites, deploy 4 new IESs, and recover data (via acoustic telemetry) from two IESs that had been deployed previously along the Abaco 26.5ºN line, and
4)to deploy a number of satellite-tracked surface drifters and ARGO profiling floats at locations in the Florida Current and the region offshore of Abaco.

The cruise began with occupation of the Florida Current CTDO2/LADCP section at 27ºN enroute to Freeport, Bahamas to clear in for research in Bahamian waters. This section measures the outflow through the Straits of Florida where AOML monitors the Florida Current volume transport via submarine electromagnetic cable.

After departing Freeport, the ship proceeded to deep water offshore of Abaco where the 26.5º N section was occupied, consisting of 23 CTDO2/LADCP stations extending from Abaco to 72º W. This section sampled the Deep Western Boundary Current and Antilles Current region east of the Bahamas and is part of an ongoing time series of these currents collected since 1984 by the AOML group. The CTDO2/LADCP stations collected on this section are also important for calibration and cross-checking of results from the western boundary moored array.

Following completion of the Abaco section, mooring servicing operations were commenced from east to west across the RAPID/MOCHA array. Servicing of the IES sites, including acoustic telemetry, was also accomplished during this period, except for three IESs which were deployed during the Abaco CTD section. After the mooring operations were completed, the planned CTDO2/LADCP section across Northwest Providence Channel had to be cancelled due to insufficient remaining time (owing to difficulties with some of the mooring deployments, see section 3.a). The ship cleared out via Freeport and finally steamed across the 27º N Florida Current section while sampling the current with shipboard ADCP and XBT profiles on the return to Harbor Branch for cruise disembarkation.
