한국근해 생태계의 장기변화

Abstract

Recent decades have seen many abrupt changes in the marine ecosystems adjacent to Korean Peninsula: Yellow Sea, East China Sea, and East Sea. The Yellow Sea is a shallow marginal sea and is broadly connected with the East China Sea to the south and contains a semi-enclosed gulf in the north, the Bohai Sea. The region is one of the more densely populated in the world with human populations. Yellow Sea and East China Sea have undergone drastic changes in the past decades as witnessed by species shifts, increasing outbreaks of HABs, and jellyfish blooms. More recently, macroalgal blooms appeared in the western coastal areas of the Yellow Sea and East China Sea. These and other changes indicate the ecosystem structure is rapidly shifting (Yoo et al, 2010).outh and contains a semi-enclosed gulf in the north, the Bohai Sea.
