We have investigated variability of the New Guinea Coastal Undercurrent(NGCUC) flowing northwestward along the New Guinea coast, and the Antarctic Intermediate Water(AAIW) with a salinity minimum around .SIGMA.THETA.=27.2 (around 700m depth in this region) using on-board observation results along 142.DEG.E line and mooring observation results at 2.DEG.30'S, 142.DEG.E. Temperature and salinity during boreal summer are lower than during boreal winter at the depth of 700-800m near the New Guinea coast, and water property of the AAIW varies seasonally. Westward current velocity at 700m and 850m depths is also large during boreal summer. Much AAIW appears to be advected during boreal summer from southeast by the strong NGCUC. (author abst.)
