Objectives

The RAPID/MOCHA program is a joint research effort between the National Oceanography Centre (Southampton, UK), the University of Miami Rosenstiel School of Marine and Atmospheric Science (RSMAS) and NOAA's Atlantic Oceanographic and Meteorological Laboratory (AOML). The objective of this program is to continuously observe the strength and structure of the Atlantic meridional overturning circulation at 26.5 N using a trans-basin observing system. The UK program is referred to as RAPID-WATCH and is a part of the UK Rapid Climate Change Program (RAPID) funded by the National Environmental Research Council (NERC). The US program is referred to as MOCHA (Meridional Overturning Circulation and Heat-flux Array) and is funded by the National Science Foundation (NSF). NOAA contributes significantly to the effort through its Western Boundary Time Series (WBTS) Program.

The goals of cruise EN-517 were to:
1. Service 5 deep-sea moorings located off the eastern Bahamas along latitude 26.5 N.
2. Service 3 pressure-inverted echo sounders (PIES) and recover data from 3 other PIES by underwater acoustic telemetry.
3. Conduct CTD (Conductivity-Temperature-Depth) and Lowered ADCP (Acoustic Doppler Current Profiler) sections across the Florida Current at 27 N, Northwest Providence Channel, and along the 26.5 N RAPID-MOCHA western boundary line east of Abaco, Bahamas.
4. Perform several additional deep water CTD casts to calibrate moored instrumentation.
5. Deploy 10 satellite tracked surface drifters at chosen locations along the cruise track.
