日本海末次盛冰期的沉积层几乎都是以交替出现的深色纹层、浅色纹层状和均质沉积物为特征。根据日本海中部和南部两个岩心记录的末次盛冰期的沉积特征和表层海水温度变化,讨论了低海平面时期东亚季风对日本海沉积环境的控制作用。24.2～17.8cal.kaBP,日本海南部纹层沉积的分布均对应了夏季风的相对增强,表明季风降水输入是引起该时期日本海底层水含氧量变化的主要原因。在夏季风的控制下,低盐富营养的东海沿岸水的强弱变化使冲绳海槽北部表层海水温度也在24.2～17.8cal.kaBP期间出现低值并剧烈变化。30～24.2和17.8～15cal.kaBP,受增强的冬季风(夏季风减弱)影响,日本海水体的流通性较强,底层水溶解氧含量相对较高。对23～17.5cal.kaBP日本海的表层海水温度出现异常高值的原因存在很多争论,一般认为是由于季风降雨输入量大于蒸发量、表层水盐度普遍降低、水体出现密度分层、水层间的垂直交换受到限制所致。
Almost all of the sediments in the submarine to late Pleistocene in Japan are characterized by alternating dark-colored layers, light-colored lamina and homogeneous sediments. Based on the sedimentary characteristics of the last glaciation recorded by two cores in the central and southern Japan Sea and the change of surface seawater temperature, the controlling effect of the East Asian monsoon on the sedimentary environment of the Japan Sea in low sea level is discussed. From 24.2 to 17.8cal.ka BP, the distribution of lamina in South Japan corresponds to the relative increase of summer monsoon, indicating that the input of monsoon rainfall is the main cause of the variation of oxygen content in Japanese submarine water during this period. Under the control of the summer monsoon, the change of water intensity in the low salt and eutrophic coast of East China Sea made the surface sea water temperature in the northern Okinawa Trough show a low value and drastic change during 24.2-17.8cal.kaBP. 30 ~ 24.2 and 17.8 ~ 15cal.kaBP. Affected by the enhanced winter monsoon (weakened summer monsoon), the seawater in Japan is more fluid and the dissolved oxygen content in the bottom is relatively higher. There are many controversies about the reason why the surface seawater temperature is abnormally high in the 23 ~ 17.5cal.kaBP Japan Sea. It is generally believed that the input of the monsoon rainfall is larger than the evaporation, and the salinity of the surface water generally decreases. The density of the water layer delaminates. Vertical exchange between the restrictions.
