In order to understand the phytoplankton community structure based on their cellsize duringlow water temperature periods, we studied 10 stations in the East Sea, Korea onMarch, 2012. The minimum standing crops of total phytoplankton were 3.4×106 cells L-1 at thestation 5. The maximum values were 7.6×106 cells L-1 at the station 8, which is two times theamount of the minimum. The carbon mass at the station 4 (6.3×108 pg L-1) was more than fortytimes higher compared with station 5 (0.08×108 pg L-1). From these results, we found a significantdifference between standing crops and carbon mass which might have caused due to their differencesin community structure and cell size. Therefore, we considered the types of plankton biomassto estimate the primary product in the specific location and/or time. The phytoplanktoncommunities were classified in 3 types: microplankton (¤20 μm), nanoplankton (⁄20 μm) andpicoplankton (⁄2 μm). In the case of picoplankton, various morphological types were observedduring the study period. These various picoplankton species were further classified as S (spherical),SF (spherical&flagella), O (oval), OF (oval&flagella) or R (rod) type, and we analyzed their communitystructure based on these categories. The picoplankton was found to be the most dominanttype at 8 stations and S type as the most popular. The picoplankton seems to be the significantorganism in the marine ecology during low water temperature periods in the coastal waters ofEast Sea. Therefore, picoplankton with scientific surveys can be considered as the database fortheir identification. In conclusion, we suggest that cell size of the phytoplankton would be the bestcriteria to accurately analyze their community structure and to reveal groups having more ecological influence.
