    Description: During the cruise SO269 (August/September 2019) on board of the German RV SONNE, we collected water with a CTD SBE911 rosette system at 81 stations (resulting in more than 600 water samples) distributed along the shelf, shelf edge and deep-sea of the northern South China Sea. We measured concentrations of chlorophyll a, phaeopigments, suspended particulate material (SPM) and nutrients 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 organic nitrogen (DON). The hydrographic data collected during this survey is available at PANGAEA (Waniek et al. 2021). Brief description of the methodology used: Nitrate, nitrite, phosphate and silicate were measured by continuous flow analysis. DOC and DON were measured by catalytic oxidation after filtration through GF/F-filter. POC and PON were measured by means of an elemental analyser after filtration through pre-combusted GF/F-filters. SPM was determined gravimetrically after by determining the difference between empty pre-combusted and loaded (sample filtrate) weighted GF/F-filter. Chlorophyll a and phaeopigments were measured using a fluorometer after ethanol extraction of the GF/F-filters.

    Description: 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.

    Description: 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. - Oxygen was measured on one sample at each station by potentiometric Winkler titration. - DOC and DN were measured by catalytic oxidation after filtered with GF/F-filters. - 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.

    Description: During the cruise POS470 on board the German R/V Poseidon, we measured temperature, salinity, dissolved oxygen, fluorescence and turbidity on 33 stations in the Madeira Basin, Northeast Atlantic in May and June 2014. We aimed to study the physical and biogeochemical conditions in the upper 2000 m of the water column in the catchment area of Kiel 276. The CTD stations are distributed along three meridians (23°W, 22°W, and 21°W) and between 30° and 37°N to locate the Azores Front. The dissolved oxygen data is noisy below 1700 m. Since there was no measurement of dissolved oxygen (Winkler titration) during the cruise, the data cannot be calibrated.
