영문 초록

In order to get the basic data of primary productivity, the distribution of chlorophyll-a and phytoplankton in the vicinity of Daesan sea area were carried out from April to October 1996. The concentration of chlorophyll-a was in the range of 1.82-3.97 mg/m¹(2.44 mg/m¹). It was relatively lower than the other west sea area. A total of 90 phytoplankton taxa induding 77 diatoms were identified from all samples collected. The dominant species of diatoms were Asterionella japonicus, Cmetoceros affinis, Coscinodiscus asterompfrJius, Skeletonema costatum in the spring, Asterionella gracia/is, Cmetoceros affinis, Coscinodiscus radiatus, C. radiatus, Skeletonema costatum in the summer, Coscinodiscus centra/is, Skeletonema costatum in the autumn. The total standing crop of phytoplankton samples was 267,150-684,250 cells/ℓ (528,715 cells/ℓ) 1n the spring, 293,860-663,720 cells/ℓ(479,246 cells/ℓ) in the summer, 276,370-672,370 cells/ℓ(498,589 cells/ℓ) in the autumn.
