Cruise Inventory Information

Long name RRS James Cook (740H) cruise JC174 (JC175)
Short name JC174 (JC175)
Objectives and Narrative The primary purpose of the cruise was to service the UK contribution to the RAPID-MOC/MOCHA mooring array.

The RAPID-MOC/MOCHA array was first deployed in 2004 to measure the Atlantic Meridional Overturning Circulation (AMOC) at 26N and has been maintained by regular service cruises since then. The servicing and redeployment of the UK moorings on this cruise are conducted under the RAPID-AMOC programme. RAPID-AMOC continues the measurements at 26N and extends these to include biological and chemical measurements in order to determine the variability of the AMOC and its links to climate and the ocean carbon sink on interannual-to-decadal time scales. The ABC Fluxes project is also funded under RAPID-AMOC and is adding biogeochemical samplers and sensors to the array, with these new instruments being deployed on the array for the first time on this cruise. The RAPID telemetry MkIII system based on the MYRTLE-X lander was deployed for the first time on the previous cruise DY039, alongside mooring EBHi, and was recovered during this cruise.

As with previous RAPID cruises we also serviced the Northern Oligiotrophic Gyre (NOG) mooring, part of the FixO3 network (more information at: http://noc.ac.uk/observatories/nog). Additional work was conducted for the MeRMEED project: (http://gtr.rcuk.ac.uk/projects?ref=NE/N001745/1), which added 24 additional temperature sensors and two 75kHz ADCPs on the WB1 mooring.

As on previous cruises we deployed a number of Argo floats supplied by the UK Met Office. In addition 6 Deep Argo floats were deployed for Scripps Institute of Oceanography.
