  As a result of Global warming, warming and freshening of the Antarctic Bottom Water (AABW) has been observed around Antarctica in recent years. In this study, we conducted basic research aiming to elucidate the mechanism by which the AABW is altered, and to clarify how the deep general circulation changes in the future. Ocean observation in the Southern Ocean along 110E and deployment and recovery of long-term moorings were continuously carried out for about one month in January every year for four years. As a result, we clarified the seasonal variation characteristics of intrusion depth in the formation of AABW and the main mechanism of material transport in the meridional direction. Furthermore, the influence of Antarctic ice sheet molten water on the alteration of AABW was evaluated. In addition, as a monitoring technique of medium-scale eddy that contribute as a key to meridional circulation, a correction algorithm was developed for satellite sea level data in the sea ice area.
