Description
Summary:Surface underway physicochemical measurements were performed in open-ocean and archipelagic coastal waters of the Macaronesia region during the POS533 cruise (from February 28 to March 19, 2019) on board the RV Poseidon. The Macaronesia region show a high variability due to its location in a coupling area between the Canary Upwelling System along the Northwest African coast and the oligotrophic open-ocean waters of the Northeast Atlantic subtropical gyre and the influence of the island interaction with the Canary Current. Thus is a key zone in terms of CO2 distribution, natural and anthropogenic carbon inventory and air-sea exchange and requires the develop of regional-scale field studies. The autonomous monitoring was carried out through the vessel track mainly downwind in the archipelagos of Cape Verde, Canary and Madeira and through the latitudinal transects that connect them. The obtained dataset includes sea surface temperature (SST), salinity (SSS) and pH values with a temporal frequency of data ...
