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十八度水温 (EDW) 的形成提供了支持，该地区从海洋到大气的热通量与世界任何地方的地表热通量一样大或更大。 俯冲、环流周围的环流和 EDW 的时间变化将使用来自大西洋环流和气候实验 (ACCE) 的 PALACE 浮标数据、从机遇号收集的 XBT 数据以及使用 MICOM 等重坐标数值的一系列研究来解决模型。对观测结果和模型输出的综合分析将侧重于确定 EDW 形成地点、确定 EDW 属性、量化特定年份形成的 EDW 数量以及 EDW 形成和形成的大规模环流影响。其与气候现象的关系。该提案是对世界海洋环流实验（WOCE）分析、解释、综合和建模阶段的贡献。
