Phytoplankton Dynamics in an Arctic Lake
Primary production measurements (C 14 ) and phytoplankton counts were made in an arctic lake between June and September 1963. Annual carbon fixation was estimated at 8.5 g/m 2 (4.0 g/m 3 ), of which approximately 22% occurred under the ice. Phytoplankton numbers varied between 2.4 and 24.1 × 10 6 ce...
