Phytoplankton Community and Phytohydrographic Characteristics of the Inside and Outside of Saemangeum Reservoir

Abstract

This study was to investigate the phytoplankton communities and phytohydrographic characteristics of the inside and outside of the Saemangeum Reservoir from May to November 2006 directly after dike construction. As the cluster analyses, phytohydrographic regions were devided into fresh river water and seawater regions, and the similarities between the sampling sites fluctuated temporarily. Distinctive phytohydrographic difference was shown between inside and outside of the dike in summer. After the dike construction, declining salinity and changing water quality have caused to change the phytoplankton communities and phytohygrographic regions.
