中文摘要
9415589将在巴西盆地两个地点(靠近西部边界和内陆)的深海中进行施密特全水柱湍流、速度剪切和精细结构测量,同时在3000米深处有目的地释放示踪剂。根据动能耗散和热方差的观测,将估计巴西盆地深处的日扩散系数,内波的能级和支持混合的机制将被记录下来。基于微观结构的扩散系数估计受到空间和时间采样条件的限制,将与Ledwell及其同事(OCE-9515598)从示踪剂分散中获得的扩散系数进行比较。此外,还将与根据WOCE深盆地实验的大规模预算确定的盆地平均混合率进行比较。
英文摘要
9415589 Schmitt Full water column turbulence, velocity shear and fine-structure measurements will be conducted in the deep ocean at two sites in the Brazil Basin (near the western boundary and in the interior) concurrently with a purposeful tracer release at 3000 m depth. The diapycnal diffusivity in the deep Brazil Basin will be estimated from the observation from the dissipation of kinetic energy and thermal variance, and the nergy levels of internal waves and the mechanisms supporting that mixing will be documented. The microstructure-based diffusivity estimates, limited by sampling constaints in space and time will compared with those obtained by the Ledwell and colleagues (OCE-9515598) from their tracer dispersion. Additional comparisons will be made with the basin-averaged mixing rates determined from the large-scale budgets of the WOCE Deep Basin Experiment.
