Proposal Number 0136215Bower / 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 0136215Bower / Lozier 该项目将收集 RAFOS 浮标数据、水文学数据和测高数据，以更好地了解流出副极地地区的水域路径。声学跟踪的 RAFOS 浮标将依次释放，部署在拉布拉多海西边界深西边界流 (DWBC) 的拉布拉多海水位处。这些花车将在三年内按季节投放，并且在它们穿过弗拉芒角附近道路交汇处时将被跟踪。 这些观测结果还将用于解决通过 DWBC 从副极地地区输出新通风水域的现有理论与最近的漂流轨迹（显示剖面浮标沿着副极地-副热带环流边界向东转向）之间的明显矛盾。 新数据还将用于解决与狭窄 DWBC 路径结构、拉布拉多海水路径的时间变化和间歇性、深海通风程度以及通风时间尺度相关的假设。
