| Summary: | IV Congress of Marine Sciences, 11-13 June 2014, Las Palmas de Gran Canaria.-- 1 page Continuous measurements of the thermohaline fields were carried out between March 22nd and April 8th on the Spanish research vessel B/O Sarmiento de Gamboa in the framework of the SPURS (Salinity Processes in the Upper ocean Regional Study) project focused on the processes responsible for the formation and maintenance of the salinity maximum associated to the North Atlantic subtropical gyre. The high spatio-temporal resolution scanning of the first 300 meters of the water column was performed with a towed undulating platform SeaSoar, equipped with two CTDs, and sensors of dissolved oxygen, fluorescence and turbidity. The obtained data allowed determining the 3D temperature and salinity fields characterized by high inhomogeneity. Various relatively fresh and warm, and salty and relatively cold waters were observed to intruded into the Surface Maximum Salinity water mass. The 3D distribution of Turner Angle values allows to detect the areas of small-scale mixing activity and helps to better understanding the interrelation between differently transformed water masses inside the sampled area Peer Reviewed
