Abstract/Summary
This report describes the trial glider operations conducted as part of the RAPID-MOC project conducted between 15 September – 24 November 2008 and 21 May – 21 July 2009 between the Canary Islands and the coast of Morocco. The RAPID-MOC mooring array at 26.5°N is designed to quantify the strength and variability of the transport of mass and heat associated with the Atlantic meridional overturning circulation (MOC). Currently the majority of the measurements are made from moored instruments. The objective of this study was to assess the contribution that autonomous gliders could make to the monitoring array. In particular the focus was on the use of gliders on the shallow eastern boundary of the North Atlantic. This is the part of the RAPID array that has suffered the greatest loss of instruments, in large part due to suspected fishing activity on the continental slope. Furthermore, initial results (Chidichimo 2009) from the first three years of the RAPID array have shown that the largest contribution to the seasonal variation in the MOC is the variability of density on the eastern boundary in the upper 1000m. It is expected that gliders will be less susceptible to loss by fishing than the moored instruments. Another advantage of gliders is that data are retrieved in real-time via Iridium satellite communications, further reducing the risk of data loss. http://www.noc.soton.soton.ac.uk/rapidmoc and/or http://www.noc.soton.ac.uk/omf/projects/glider
