Biogeographical classifications of the study area based on the similarity of community compositions of diatoms (A) and haptophytes (B). Dots of the identical color indicate locations with the identical group. The sampling months are shown in the figures. Pie charts indicate the relative contribution of each genus to the total at 40°N and 20°N on the 160°W transect, and 60°N, 40°N, 20°N, 0°N, 20°S and 40°S on the 170°W transect. The base figure was created using GMT version 5.4.1.
