1987～1990年日本实施了一项为期4年的西北太平洋深层海水环流研究计划,其有关情况已在文献[1]中作了介绍。目前该项研究已进入收尾阶段。本文主要介绍迄今所取得的成果。 一、深层海水环流 1.北太平洋主体西侧深层边界流 在综合这次研究所获实测资料的基础上,得到北太平洋主体西测深层边界环流图(图1)。该图证实了文献[1]中图2所示的假设图,特别是证实了西侧边界流的存在。 From 1987 to 1990, Japan implemented a 4-year research program on the deep sea water circulation in the western North Pacific. The relevant situation has been introduced in [1]. The research is now at the final stage. This article describes the results achieved so far. 1. Deep Seawater Circulation 1. Deep Boundary Flow on the West Side of the North Pacific Ocean On the basis of the measured data obtained from this study, a deep boundary circulation map of the main body of the North Pacific Ocean is obtained (Figure 1). This figure confirms the hypothetical diagram shown in Fig. 2 in [1], especially confirming the presence of the western boundary flow.
