Abstract
We investigated the size-fractionated biomass and species composition of phytoplankton to understand latitudinal differences of phytoplankton structure in the eastern part of Yellow Sea in April and August 2012. Surveyed stations were selected along lines from coastal to off-shore waters located at two latitudes (34.5 and 36°N). In the surface waters (0-20m), total chlorophyll-a (chl-a) concentration was higher in spring (avg. 2.88 ㎍ L-1) than in summer (avg. 1.89 ㎍ L-1) at both latitudes. Micro-sized chl-a occupied over 51.4% of total biomass at both latitudes in spring, while nano-sized chl-a occupied over 58.4% at both latitudes in summer. In bottom waters (20m-bottom), total chl-a concentration was higher in summer (avg. 1.14 ㎍ L-1) than in spring (avg. 0.76 ㎍ L-1) at both latitudes. Phytoplankton standing crops in surface waters were higher in spring (avg. 2.17 cells L-1) than in summer (avg. 1.08 cells L-1) at both latitudes. In bottom waters, standing crops of phytoplankton were higher in summer (avg. 0.81 cells L-1) than in spring (avg. 0.65 cells L-1) at both latitudes. In surface waters, micro-sized (>20㎛) diatoms dominated at both latitudes in spring. In summer, nano-sized diatoms (3-20㎛) were abundant at the north latitude, while nanoflagellates predominated at the south latitude. In bottom waters, nanoflagellates dominated at both latitudes in summer, whereas Paralia sulcata and Skeletonema costatted along lines from coastal to off-shore waters located at two latitudes (34.5 and 36°N). In the surface waters (0-20m), total chlorophyll-a (chl-a) concentration was higher in spring (avg. 2.88 ㎍ L-1) than in summer (avg. 1.89 ㎍ L-1) at both latitudes.
