Oceanographic data acquired during the SAGA-REC Cruise (29HE20230408) on board the Research Vessel Hespérides in 2023. SAGA: The South Atlantic GAteway in the global conveyor belt. The general objective of the main SAGA project is to quantify and monitor the returning limb of the Atlantic Mmain meridional Overturning Circulation (AMOC) in the South Atlantic Ocean, with special attention to the interior-ocean zonal flows linking the eastern and western South Atlantic basins. To complete tasks of the main project, in 2021 were deployed a series of devices to measure different oceanographic variables at a depth between 2 and 4 kilometres deep in 7 seabed locations along the 10ºW meridian and between 34ºS and 19ºS. The main objective of the present SAGA REC cruise consists in the recovery of three previosly imstalled mooring with corresponded equipment and, in case of favourable meteorological conditions, to perform the CTD casts untill the bottom in the places where the mooring were installed and where the PIESs (Pressure Inverted Echo Sounder) are still remain to measure. Additionally is planned to performe the vertical hydrographyc transection in the shelf area of Uruguay.
