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).

支持研究在北大西洋西部的十八度水（EDW）的形成，从海洋到大气的热通量是一样大，或大于在世界任何地方的表面热通量。 俯冲，环流周围的环流，和EDW的时间变化将使用PALACE浮动数据从大西洋环流和气候实验（ACCE），XBT数据收集的机会，和一系列的研究，使用MICOM等密坐标数值模式。对观测和模式输出的综合分析将集中在EDW形成地点的识别、EDW性质的识别、给定年份EDW形成量的量化以及EDW形成的大尺度环流影响及其与气候现象的关系上。这一建议是对世界海洋环流实验的分析、解释、综合和建模阶段的贡献。
