Abstract:

The dataset contains pore water macronutrient (nitrate+nitrite, nitrite, ammonium, phosphate) concentration measurements, obtained from seven sediment cores collected from the Greenland margin and the Labrador Sea. Porewaters were extracted from the sediment cores using Rhizon samplers and frozen for transport. The frozen samples were thawed according to GoSHIP protocols and analysed for inorganic macronutrients using a SEAL analytical AAIII segmented flow colorimetric auto-analyser. Seawater nutrient reference materials (KANSO Ltd. Japan) were also analysed to check analyser performance and to guarantee the quality control of the final reported data. The typical uncertainty of the analytical results were between 2-3%, and the limits of detection for nitrate and phosphate were 0.02 mmol/m3, and 0.01 mmol/m3 for nitrite. For full methods and analytical quality control, see Hendry et al., 2019. The samples were collected as part of the European Research Council project ICY-LAB (ERC-2015-STG grant agreement number 678371).
