REOCIRC is a basic natural science research project that applies state of the art instrumentation and theory to study remote sensed ocean circulation and heat fluxes towards the Arctic Ocean and the corresponding environmental mass changes in response to the estimated heat fluxes. REOCIRC was designed to consist of a field campaign collecting in situ data parallel to a satellite data processing group in order to obtain high precision water level estimates and therefore a more precise ocean circulation pattern in the Fram Strait region towards the Arctic Ocean. 3 x Ocean Bottom Recorder (OBP) moorings and one ocean current/hydrography mooring were deployed for two years at the northwestern corner of Spitsbergen were the mooring line captured the water transport in the Svalbard Branch and the Spitsbergen Polar Current (SPC). On the August 28, 2014, OBPs (sbe-26) were installed at (YP1) 79°48.0'N, 10°44.8'E, in about 29 m of water, at (YP2) 79°50.4'N, 10°29.6'E, in about 110 m of water and at (YP3) 80°10.5'N, 08°8.7'E, in water about 550 m deep. In between the OBP moorings, close to YP3, a current meter mooring (YPC) measured current and hydrography in the water column from 50 m to 500 m depth. The YPC mooring was equipped with three current meters, one Aandreaa Seaguard (SG) at 60 m depth and two Aanderaa RCM9, positioned at 200 m and 500 m depth. Three SBE 37 Microcats measured conductivity and temperature (80, 200, and 300 m depth) and 15-16 Vemco minilog II (vmc) for temperature measurements were distributed vertically along the mooring.
