The investigation includes measurements of primary production in situ, light extinction at 450 nm, 522 nm, 583 nm and 653 nm, and phytoplankton composition at one station in Straumsbukta (60° 33 . 5'N, 18° 37'E) at four different seasons. Primary production varied with a factor of 10 SUP-13 from winter to summer, and production in summer was at noon 60 times that of midnight. Size fractions passing a 5 mu m nylon net conributed with 6% (summer) - 73% (winter) of the production in surface water samples. Nanoplankton flagellates, Phaeocystis pouchetii, Chaetoceros debilis and Coccolithus (Emiliania) huxleyi were the main phytoplankton species in December, April, July and September, respectively.
