This dataset contains biogeochemical samples analyzed by the Plankton Chemistry Laboratory at the Institute of Marine Research (IMR), mainly from the Norwegian Sea but also including the Iceland and Greenland Seas. Number of surveys and stations visited has varied greatly over the last 3 decades. One major effort by the IMR is the annual Ecosystem Survey in summer, with multiple trawl surveys, net tows and CTD water sampling over the course of a month. This month-long exercise also include companion vessels from Iceland and the Faroe Islands surveying their own territorial waters (only trawl surveys and net tows). Two transects are also visited multiple times each year by the IMR (Svinøy-NorthWest and Gimsøy-NorthWest), in addition to other water sample collections from short-term projects visiting the region. Each CTD cast is sampled for dissolved inorganic nutrients (nitrate, nitrite, phosphate, silicate) and phytoplankton pigments (ChlA, Phaeo) at predetermined depths and 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. This unique data set has seen limited 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).
