Effects of Thermobaricity and T-S Variability on Large-Scale Ocean Dynamics

0217075工具将对现有的细组织和微观结构数据进行分析。这些数据来自最近对海洋混合过程的两项调查：巴西盆地示踪剂释放实验和罗曼什断裂带环流研究，包括高分辨率剖面仪的垂直剖面观测数据和系泊流计测量数据。这些数据中的几个信号将被探索、记录和呈现在科学文献中，这些文献涉及(1)在粗略水深测量之上（在副热带纬度和赤道）的深海中精细剪切和应变的性质以及相关的湍流耗散，(2)海洋中脊断裂内的流动，(3)在赤道捕获的深射流场中湍流耗散的强度和空间分布。(4)远离赤道附近热带纬度的中深度内波场强度及其混合。这些项目的共同目标是提高对深海混合和潜流运输的理解。

0217075 TooleAnalysis of existing finestructure and microstructure data will be conducted. The data, derived from two recent investigations of ocean mixing processes: the Brazil Basin Tracer Release Experiment and the study of Circulation in the Romanche Fracture Zone, consist of vertical profile observations from the High-Resolution Profiler and moored current meter measurements. Several signals in these data will be explored, documented, and presented in the scientific literature that address (1) the nature of the finescale shear and strain and the associated turbulent dissipation in the abyssal ocean above rough bathymetry (at subtropical latitudes and on the equator), (2) the flow within a mid-ocean ridge fracture, (3) the intensity and spatial distribution of turbulent dissipation in a field of equatorially trapped deep jets, and (4) the intensity of the mid-depth internal wave field and associated mixing at tropical latitudes away from the immediate vicinity of the equator. The projects are related by the common goal of improving understanding of mixing and diapycnal transport in the deep ocean.
