High resolution environmental variability during the last glaciation using results from lake sediment core and marine sediment core.

从日本小川原湖（Lake Ogawara）的一个滨海半咸水湖底部采集了每年一次的层状沉积物柱样。20米的岩心代表了大约16,000年来古环境信息的连续档案。末次冰期以来流入小川原湖的海水至少从距今10,000年开始。大约在距今6,000年左右，这个湖泊被温暖的海水充满，这被称为日本的绳纹海侵，与全球海平面上升相对应。6, 000 yr BP后湖水由淡水变为淡水，100~ 200 yr BP后湖水由微咸水变为咸水。6, 000 yBP左右注入小川原湖的暖海水来源于对马暖流，对马暖流的北移促进了西北太平洋中层水的形成，并与西北太平洋Shimikita近海的海洋沉积物柱芯结果进行了比较。

The annually laminated sediment cores were collected from the bottom of a coastal brackish lake, Lake Ogawara, Japan. The 20-m cores represent a continuous archive of palaeoenviromental information covering approximately the last 16,000 years. The inflow of seawater into Lake Ogawara since the last glaciation started from at least 10,000yr BP. The lake was filled with warm seawater around about 6,000yr BP, which is called the Jomon Transgression of Japan, corresponding to the global sea-level rise. Although the lake water changed to fresh after 6,000yr BP, the lake became brackish from 100~200yr BP until the present. The warm seawater, which filled Lake Ogawara around 6,000y BP, originated with the Tsushima Warm Current, the northward migration of this current increased the formation of intermediate water in the western North Pacific, comparison with the results of the marine sediment core collected off Shimikita in the western North Pacific.
