Collaborative Research: A new Account of Souther Ocean Waters: Characteristics, Variability, Production

世界海洋环流实验（WOCE）最近收集的水文站质量控制数据库将用于为南纬25度以南地区创建高分辨率气候学。基于气候学和客观测绘的属性域，将创建南大洋水域的精细体积普查。在气候学和体积普查中变化较大的地区将使用剖面数据作为时间和中尺度变率的可能地点进行检查。估计与大陆架/斜坡上产生新的南极深水和底部水域有关的水质量转换和混合率将来自对经典示踪剂分布、体积普查数据和平均跨坡速度场的定量分析。更广泛的影响：我们将制作一系列地图和垂直剖面，作为静态数据，供我们网站的访问者浏览，以说明南大洋的水团结构和环流。交互式工具将允许用户选择特定的数据集或子集，不同的网格和相关长度，以及几个绘图选项来生成自定义图形。这些特征可以作为描述海洋学和制图技术教学的课堂辅助工具。网格化的气候学和人口普查数据将在网站上提供，供其他研究人员使用。还将制作一个高质量的数字版本，以列入世界环境组织地图集的印刷版。

A recently quality-controlled database of hydrographic stations collected by the World Ocean Circulation Experiment (WOCE) will be used to create a high-resolution climatology for the region south of 25 S. A fine-scale volumetric census of Southern Ocean waters will be created based on the climatology and objectively mapped property fields. Regions of high variance in the climatology and volumetric census will be inspected using profile data as possible sites of temporal and mesoscale variability. Estimates of water mass transformations and mixing rates associated with the production of new deep and bottom Antarctic waters over the shelf/slope regime will result from the quantitative analysis of classic tracer distributions, volumetric census data, and mean cross-slope velocity fields. Broader impacts:A collection of maps and vertical sections will be produced as static figures that can be browsed by visitors to our web site to illustrate the water mass structure and circulation of the Southern Ocean. An interactive tool will allow users to choose particular datasets or subsets, different grids and correlation lengths, and several plotting options to generate custom figures. These features may be useful as classroom aids in the teaching of descriptive oceanography and mapping techniques. The gridded climatology and census data will be made available on the web site for use by other researchers. A high quality version of the figures will also be produced for inclusion in a printed version of the WOCE atlases.
