Objectives and Approach

To obtain a complete synoptic view of the vertically-layered structure and major components of the circulation of the Japan/East Sea, researchers conducted a complete shipboard surface-to-bottom hydrographic survey of the entire Japan/East Sea in conjunction with Russian, Korean, and Japanese investigators.

Two hydrographic surveys (temperature and salinity) of the Japan/East Sea were completed, one during summer 1999 and one during winter 2000. Russian and Korean collaborators carried out related chemical and nutrient analyses for dissolved oxygen, partial pressure of CO2, nitrogen, phosphate and silicate, and other chemical tracers. Data will be analyzed in conjunction with other investigators and modelers to elucidate the circulation.
