Stressor 2019: Concentrations of chlorophyll a, nutrients (silicate, phosphate, nitrate, nitrite), POC, PON and biogenic silica in the northern Norwegian Sea

Data on the concentrations of chlorphyll a, nutrients, particulate organic carbon and nitrogen, and biogenic silica are presented from 28 stations in the northern Norwegian Sea. Data were collected during a research cruise with R/V Helmer Hanssen 27 April to 12 May 2019. All data are based on filtrations of seawater that was collected by Niskin bottles mounted on a CTD-rosette from discrete depths along vertical profiles. Analysis followed standard procedures and used standard equipment for seawater analysis , more in the README file.
