| contents | During the cruise POS459 on board the German R/V Poseidon, we collected water with a CTD SBE 11plus equipped with 14 Hydrobios free flow bottles of 10 L each in 9 stations (resulting in almost 100 samples) 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, in September 2013. 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). The physical oceanography associated with this dataset can be found at https://doi.org/10.1594/PANGAEA.949122. Brief description of the methodology used: - Nitrate, nitrite, phosphate, and silicate were measured by continuous flow analysis. - POC and PON were measured by means of an elemental analyser after filtered with pre-combusted GF/F-filters. - Suspended particulate material (SPM) was determined gravimetrically after pre-combusted and weighted GF/F-filters filtration. - Chlorophyll a and phaeopigments were measured using a fluorometer after ethanol extraction of the GF/F-filters. |
