This dataset contains all biogeochemical samples analyzed by the Plankton Chemistry Laboratory at the Institute of Marine Research (IMR) from the Barents Sea and Arctic regions. The number of surveys and stations visited in the Barents Sea and the Arctic has varied over the last 30 years. As of today, the annual Ecosystem Survey is still taking place as a Russian-Norwegian effort, and 2-3 research vessels from IMR will cover the entire Norwegian side of the Barents Sea with trawl surveys, net tows and CTD water sampling. As the summer ice edge has receded further north in recent years, the region north of the Barents Sea has been added to these surveys. In addition to the annual Ecosystem Survey, there are two trans-sectional core surveys (the Fugløya-Bjørnøya and the Vardø-North transects) visited multiple times each year. Water samples are also collected from a number of short-term sampling projects from ships operated by the IMR visiting the region. Each CTD cast is sampled for dissolved inorganic nutrients (nitrate, nitrite, phosphate, silicate) and phytoplankton pigments (ChlA, Phaeo) at predetermined depths, for later analysis at IMR. On occasion, short-term projects have performed Winkler DO titrations (DOW) and particulate organic carbon and nitrogen (POC, PN) determinations. Parts of this unique data set has seen some use over the years, but the entire time-series is a great contribution towards global ocean research and climate change investigations. A description of analytical methods is available (Appendix-1).
