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).

提供了支持，以研究北大西洋西部的18度水（EDW）的形成，那里的热通量从海洋到大气的热通量大于或大于世界上任何地方的表面热通量。 使用大西洋循环和气候实验（ACCE），从机会船收集的XBT数据以及使用MICOM ISOMOM ISOPYCLECNal坐标数值模型收集的XBT数据，使用宫殿浮点数据来解决EDW周围的俯冲，循环以及EDW的时间变化。对观测值和模型输出的综合分析将集中在识别EDW形成位点，EDW特性的识别，对给定年份形成的EDW数量的量化以及EDW形成的大规模循环影响及其与气候现象的关系。该建议是世界海洋循环实验（WOCE）的分析，解释，合成和建模阶段的贡献。
