Continued Analysis of C-Salt Data

巴巴多斯以东地区的主温跃层在温度和盐度剖面上表现出一种准永久的垂直结构，其特点是厚度约50米的混合层，中间隔着1至10米的薄层，这些性质具有非常强的梯度。这在垂直剖面上产生了数百公里量级的水平相干尺度的阶梯效应。盐指作用和双重扩散作用是该区的主要混合机制。施密特将分析加勒比片层横断面(CSALT)计划期间在该地区收集的数据。已经用光学微结构仪器鉴定了盐指，但某些细节与理论预测相差很大。将使用微观结构、细微尺度和大尺度性能的分析和数值模型。这项研究将对我们理解海洋中的混合和水团的形成做出有价值的贡献。

The main thermocline in the region east of Barbados shows a quasi-permanent vertical structure in the temperature and salinity profiles characterized by well mixed layers about 50m thick separated by thin layers of 1 to 10m with very strong gradients in these properties. This produces a staircase effect in the vertical profiles with horizontal coherent scales on the order of several hundred kilometers. Salt fingering and double diffusion are believed to be the dominant mixing mechanisms in this region. Schmitt will analyze the data collected in this region during the Caribbean Sheets and Layers Transects (CSALT) program. Salt fingers have been identified with optical microstructure instru- ments but certain details differ considerably from theoretical predictions. Analytical and numerical models of microstructure, fine scale and large scale properties will be used. This study will be a valuable contribution towards our understanding of mixing in the ocean and formation of water masses.
