Support is provided to study the formation of eighteen-degree water (EDW) in the western North Atlantic, where the heat flux from the ocean to the atmosphere is as large as or larger than the surface heat flux anywhere in the world. Subduction, circulation around the gyre, and temporal variability of the EDW would be addressed using PALACE float data from the Atlantic Circulation and Climate Experiment (ACCE), XBT data collected from ships of opportunity, and a series of studies using the MICOM isopycnal coordinate numerical model. The combined analyses of the observations and model output will focus on the identification of the sites of EDW formation, the identification of EDW properties, the quantification of the amount of EDW formed for a given year as well as large scale circulation impacts of EDW formation and its relation to climate phenomena. This proposal is a contribution to the Analysis, Interpretation, Synthesis and Modeling phase of the World Ocean Circulation Experiment (WOCE).

为研究北大西洋西部18度水(EDW)的形成提供了支持，那里从海洋到大气的热通量等于或大于世界任何地方的地表热通量。将使用来自大西洋环流和气候实验(ACCE)的皇宫浮标数据、从机会号船收集的XBT数据以及使用Micom等轴坐标数值模式的一系列研究来处理EDW的俯冲、环流和时间变异性。对观测和模式输出的综合分析将侧重于确定EDW形成的地点，确定EDW的性质，量化某一年形成的EDW的数量，以及EDW形成的大尺度环流影响及其与气候现象的关系。这项建议是对世界海洋环流实验(WOCE)的分析、解释、综合和模拟阶段的贡献。
