Figure 5.1.5. Maps showing plankton community composition and abundance at all sampled stations North of 75°N (left) and South of 75°N (right). Pie chart radii scale to average cell concentrations, scaling varies between panels to allow for visualization; maximum radii represent 8.9×105 cells ml-1 (N of 75°N) and 5.6×106 cells ml-1 (S of 75°N ). Divisions within pie charts show the contributions from broad taxonomic groups. All groups which comprised ≤ 1% of the community at a given station are summed for ease of visualization.
