Proposal Number 0136098Bower / LozierThis project will collect RAFOS float data, hydrographic data and altimetry to pursue a greater understanding of the pathways of waters exiting the subpolar regions. Sequentially released, acoustically-tracked, RAFOS floats will be deployed at the Labrador Sea Water level in the Deep Western Boundary Current (DWBC) along the western boundary of the Labrador Sea. The floats will be released on a seasonal basis for three years and they will be tracked as they transit through the junction in pathways near Flemish Cap. These observations will also be used to address an apparent contradiction between existing theory of the export of newly ventilated waters from the sub-polar regions via the DWBC and recent drifter tracks that show the profiling floats turning eastward along the subpolar-subtropical gyre boundary. The new data will also be used to address hypothesis related to the structure of the narrow DWBC path, the temporal variability and intermittency in Labrador Sea Water pathways, the extent to which the deep ocean is ventilated, and the time scale of that ventilation.

提案编号0136098 Bower/Lozier该项目将收集RAFOS浮标数据、水文数据和测高数据，以更好地了解亚极地地区沃茨的路径。RAFOS浮标将被顺序释放，声学跟踪，部署在拉布拉多海的水平面上，沿着拉布拉多海的西部边界，在西部深层边界流（DWBC）中。这些漂浮物将在三年内按季节释放，当它们通过佛兰芒角附近通道的交叉口时，将对其进行跟踪。 这些意见也将被用来解决一个明显的矛盾之间的现有理论的出口新通风沃茨从副极地地区通过DWBC和最近的漂流者的轨迹，显示剖面浮标转向东沿着副极地-副热带环流边界。 新的数据还将用于解决与窄DWBC路径的结构，拉布拉多海水路径的时间变化和不稳定性，深海通风的程度以及通风的时间尺度有关的假设。
