Abstract

To investigate the research state and characteristics of dinoflagellate cyst along theKorean coastal waters, this work analyzed 45 studies conducted in the Korean coasts and basin,the south of Jeju, East China Sea including some part of the Yellow Sea. It was found that theresearch on dinoflagellate cyst began in the later half of the 1980s in Korea, and that the researchareas focused on eutrophied regions where a red tide occurred or on the seas where coastal developmentoccurred. In other words, no research on the East Sea was found. In terms of research contents,there were various studies on analysis of cyst assemblage, tracking of the changes in marine environmentlike process of eutrophication, roles as a seed population in occurrence of a red tide, creationof cyst by use of sediment trip and tracking of its changes, morphological changes by the changeof pH concentration in the hypoxia zone of eutrophied region, germination of a specific species, andother international-level studies. Species composition and cell density also varied in the Koreancoastal waters. However, much research on dinoflagellate cyst in Korea is not systematic, and isfragmentary and individual and hencesuffers from great limitations. The research results so farhave focused only on specific regions, and sporadic research had been conducted by specific researchgroups. Dinoflagellate cyst of surface sediments represents the accumulation index of pelagic environmentin the sea and is a useful index to understand the marine environment efficiently. In conclusion,Korea requires organized human resources and collaborative research on dinoflagellate cystwhich in turn should be considered as a component of marine ecosystem and as an essential aspectof marine biology.
