RRS Discovery Cruise D324, 06 Oct-09 Nov 2007. RAPID Mooring Cruise Report
This report describes the mooring operations and underway measurements conducted during RRS Discovery Cruise D324 conducted between 6th October 2007 and 9th November 2007. This cruise was completed as part of the United Kingdom Natural Environment Research Council (NERC) funded RAPID Programme to monitor the Atlantic Meridional Overturning Circulation at 26.5ºN. The primary purpose of this cruise was to service the Eastern Boundary and Mid-Atlantic ridge sections of the 26.5ºN mooring array. The array was first deployed in 2004 during RRS Discovery cruises D277 and D278 (SOC cruise report number 53), and serviced in 2005 during RRS Charles Darwin Cruise CD170 and RV Knorr Cruise KN182-2 (NOCS cruise report number 2), RRS Charles Darwin Cruise CD177 (NOCS cruise report number 5), in 2006 on RV Ronald H. Brown Cruise RB0602, RRS Discovery Cruise D304 (NOCS cruise report number 16) and FS Poseidon Cruises P343 and P345 (NOCS cruise report number 28), and in 2007 on RV Ronald H. Brown Cruise RB0701 (NOCS cruise report number 29). Cruise D324 had two legs with the first a transit from Falmouth, UK to Santa Cruz de Tenerife, Tenerife and the second sailing from, and returning to, Santa Cruz de Tenerife, Tenerife. The moorings serviced on this cruise were deployed on D304, P343 and P345, along with two landers deployed on CD170. The Rapid-MOC array of moorings was deployed across the Atlantic to set up a pre- operational prototype system to continuously observe the Atlantic Meridional Overturning Circulation (MOC). This array will be further refined and refurbished during subsequent years as part of the Rapid-WATCH programme. The instrumentation deployed on the array consists of a variety of CTD loggers, current meters, bottom pressure recorders, and Inverted Echo-sounders, which, combined with time series measurements of the Florida Current and wind stress estimates, can be used to determine the strength and structure of the MOC at 26.5ºN.

Abstract
This report describes the mooring operations and underway measurements conducted during RRS Discovery Cruise D324 conducted between 6th October 2007 and 9th November 2007. This cruise was completed as part of the United Kingdom Natural Environment Research Council (NERC) funded RAPID Programme to monitor the Atlantic Meridional Overturning Circulation at 26.5ºN. The primary purpose of this cruise was to service the Eastern Boundary and Mid-Atlantic ridge sections of the 26.5ºN mooring array. The array was first deployed in 2004 during RRS Discovery cruises D277 and D278 (SOC cruise report number 53), and serviced in 2005 during RRS Charles Darwin Cruise CD170 and RV Knorr Cruise KN182-2 (NOCS cruise report number 2), RRS Charles Darwin Cruise CD177 (NOCS cruise report number 5), in 2006 on RV Ronald H. Brown Cruise RB0602, RRS Discovery Cruise D304 (NOCS cruise report number 16) and FS Poseidon Cruises P343 and P345 (NOCS cruise report number 28), and in 2007 on RV Ronald H.

Cruise D324 had two legs with the first a transit from Falmouth, UK to Santa Cruz de Tenerife, Tenerife and the second sailing from, and returning to, Santa Cruz de Tenerife, Tenerife.
