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为准永久垂直结构，其特征是约50m厚的混合层被1 ~ 10m的薄层隔开，这些性质具有很强的梯度。这在垂直剖面上产生了阶梯效应，水平相干尺度在几百公里左右。盐指作用和双重扩散是该地区主要的混合机制。施密特将分析在加勒比薄片层样带（CSALT）项目中收集到的数据。用光学显微结构仪器已经确定了盐指，但某些细节与理论预测有很大的不同。将使用微观结构、细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作出有价值的贡献。

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.
