During the cruise POS470 on board the German R/V Poseidon, we collected water with a CTD SBE911plus equipped with 14 Hydrobios free flow bottles of 5 L each in 31 stations (resulting in more than 300 samples) and during transect time in the Madeira basin region, Northeast Atlantic. We aimed to study the physical and biogeochemical conditions in the upper 2000 m of the water column around the catchment area of Kiel 276 in May/June 2014. We measured concentrations of chlorophyll a, phaeopigments, suspended particulate material (SPM), and nutrients such as nitrate, nitrite, phosphate and silicate. Also, we determined concentrations of particulate organic carbon (POC) and particulate organic nitrogen (PON) as well as dissolved organic carbon (DOC) and dissolved nitrogen (DN). The physical oceanography during the survey is available at PANGAEA (https://doi.org/10.1594/PANGAEA.949132).Brief description of the methodology used:- Nitrate, nitrite, phosphate and silicate were measured by continuous flow analysis.- ... : Physical data was previously published and can be found inside the complete CTD data of POS470:Waniek, Joanna J; Frazão, Helena C; Mars, Robert (2022): Physical oceanography during POSEIDON cruise POS470 in Madeira basin in May/June 2014.
