The 26 North dataset comprises moored temperature, conductivity and salinity, current velocity, acoustic travel time and bottom pressure time series. Data have been collected in the North Atlantic between latitudes of 23.7 degrees N and 28 degrees N in three sub -arrays at the Western Boundary (76.9 degrees W to 69.4 degrees W), Mid-Atlantic Ridge (52.1 degrees W to 40.9 degrees W) and Eastern Boundary (24.2 degrees W to 12.2 degrees W ). A number of instrumented moorings, some of which are full depth, have been deployed in each sub-array. Data have been collected since February 2004 and the moorings have been turned around every year. Data have been collected using a variety of moored instrumentation including conductivity-temperature-depth (CTD) sensors, current meters, Bottom Pressure Recorders (BPR), Inverted Echo Sounders (IES) and Acoustic Doppler current profilers (ADCPs). Data are collected in order to calculate and continuously monitor the Meridional Overturning Circulation (MOC) and provide a long term time series of the strength of the MOC. The 26 North dataset comprises moored data collected by the RAPID: monitoring the Atlantic Meridional Overturning Circulation at 26.5 degrees N since 2004 (RAPIDMOC) project and the Meridional Overturning Circulation and Heat-flux Array (MOCHA) project. Data are held at the British Oceanographic Data Centre.
