| 摘 要： | 利用Argo资料和《世界海洋数据集2001版》(WOD01)温盐历史资料,通过对代表性等位势面上盐度分布的分析,探讨了次表层和中层等不同层次上印尼贯通流(ITF)的起源与路径问题.分析结果表明,ITF的次表层水源主要来自北太平洋,中层水源地既包括北太平洋、南太平洋,同时也不能排除有印度洋的可能性.在印度尼西亚海域西部,ITF的次表层和中层水源分别为北太平洋热带水(NPTW)和中层水(NPIW),经苏拉威西海、望加锡海峡到达弗洛勒斯海,层次越深特征越明显.在印度尼西亚海域东部,发现哈马黑拉-新几内亚水道附近存在次表层强盐度锋面,阻隔了南太平洋热带水(SPTW)由此进入ITF海域;中层水具有高于NPIW和来自南太平洋的南极中层水(AAIW)的盐度值,既可能是AAIW和SPTW在当地发生剧烈垂直混合而形成,也可能是来自印度洋的AAIW向北延伸进入ITF的结果.

| Abstract: | Based on Argo data and historic temperature/salinity data from the World Ocean Database 2001 (WOD01),origins and spreading pathways of the subsurface and interm ediate water masses in the Indonesian Throughflow(ITF) region were discussed by analyzing distributions of salinity on representative isopycnal layers.Results were shown that,subsurface water mostly comes from the North Pacific while the intermediate water originates from both the North and South Pacific Ocean,even possibly from the Indian Ocean.Spreading through Sulawesi Sea,Makassar Strait,reach Flores Sea,the North Pacific Subsur face Water and North Pacific Intermediate Water dominate the western part of the Indonesian Archipelago.Furthermore as the depth increases,the features of the North Pacific sourced water masses become more obvious.In the eastern part of the waters,high salinity South Pacific Subsurface Water is blocked by a strong salinity front between Halmahera and New Guinea.Int er mediate watert here owns salinity higher than North Pacific Intermediate Water and Antarctica Intermediate Water(AAIW),possibly coming from thevertical mixing between subsurface water and the AAIW from the South Pacific,and possibly coming from the northward extending of the AAIW in the Indian Ocean as well. |
