Physical oceanography during POSEIDON cruise POS459 in Madeira basin in September 2013

This set provides 12 CTD profiles of temperature, salinity, dissolved oxygen, fluorescence, turbidity, and sound velocity measured on board the German R/V Poseidon in September 2013, in the Madeira basin region, Northeast Atlantic. We aimed to study the physical and biogeochemical conditions of the water column along the 22°W meridian, north and south of the Azores Front.
