Nutrient concentrations in sea ice during POLARSTERN cruise PS106/1 (ARK-XXXI/1.1)


Samples for nutrient concentrations in sea ice were collected during the Polarstern expedition PS106.1. The ice drift expedition took place between 4 - 15 June 2017, north of Svalbard (Macke and Flores, 2018). Sea ice cores were collected using a Kovacs Mark II 9cm drill ice corer. In all ice stations, the first ice core was used for in situ ice temperature measurements, and the second one for methane concentration, stable carbon isotopic signature of methane, bulk ice salinity and nutrient concentrations (Verdugo et al., 2021). Nutrient concentrations in bulk ice (nitrate+nitrite, phosphate, silicate, nitrite, and ammonia) were analyzed on a four channel SEAL Analytical nutrient AutoAnalyzer 3 (AA3, Grasshoff et al., 1983).
