SHEBA Upper Ocean CTD and Thermal Microstructure, Western Arctic Ocean, Version 1.0

This data set includes Conductivity, Temperature, Depth (CTD) measurements along with thermal microstructure data (such as, turbulent thermal variance, turbulent kinetic energy, and vertical temperature gradient) collected from 12 October 1997 to 30 September 1998. The storage, redistribution, and ultimate release of the energy contributed by incoming shortwave radiation has major effects on the thickness and seasonal evolution of sea ice cover and the state of the upper ocean. As part of the Surface Heat Budget of the Arctic (SHEBA) project, this research was designed to (1) investigate upper ocean processes and their role in ice-albedo feedback, and (2) develop and test suitable models or parameterizations for use in large-scale simulations. Data are in space-delimited ASCII text format and are available via FTP.

本数据集包含1997年10月12日至1998年9月30日采集的电导率、温度、深度（Conductivity, Temperature, Depth, CTD）测量数据，以及热微结构数据（包括湍流热方差、湍流动能与垂直温度梯度）。入射短波辐射所携带的能量的储存、再分配与最终释放，对海冰覆盖的厚度、季节演化以及上层海洋的状态具有显著影响。作为北极表面热量平衡（Surface Heat Budget of the Arctic, SHEBA）项目的组成部分，本研究旨在达成两大目标：（1）探究上层海洋过程及其在冰反照率反馈中的作用；（2）开发并测试适用于大规模模拟的合适模型或参数化方案。数据集采用空格分隔的ASCII文本格式，可通过FTP获取。
