Mapset: Mean Sea Surface Currents each Quarter (in the Australian Region)

Set of quarterly maps of mean sea surface currents derived from annual and semi-annual temperature and salinity cycles stored in CARS2000. CARS is a set of seasonal maps of temperature, salinity, dissolved oxygen, nitrate, phosphate and silicate, generated using Loess mapping from all available oceanographic data in the region. It covers the region 100-200E, 50-0S, on a 1/2 degree grid, and on 56 standard depth levels. The data was obtained from the World Ocean Atlas 98 and CSIRO Marine and NIWA archives. It was designed to improve on the Levitus WOA98 Atlas, in the Australian region. These maps have been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project. Sea surface height not defined for depths less than 400m. Variations in onscreen colour representation or printed reproduction may affect perception of the contained data.

本数据集为基于CARS2000中存储的年周期与半年度温盐循环生成的季度平均海表流场图集。CARS是一套采用局部加权回归（Loess）制图方法，基于研究区域内所有可用海洋观测数据生成的温度、盐度、溶解氧、硝酸盐、磷酸盐及硅酸盐季节图集。该图集覆盖东经100°至200°、南纬50°至0°的海域，采用0.5度网格分辨率，并包含56个标准深度层。本数据集数据来源于世界海洋图集1998（World Ocean Atlas 98）以及CSIRO Marine与NIWA的档案库。其旨在优化澳大利亚区域内莱维图斯世界海洋图集1998（Levitus WOA98 Atlas）的相关内容。该图集由CSIRO为国家海洋办公室制作，作为其通过‘国家海洋生物区划’项目持续推进自然资源规划与管理工作的一部分。海表面高度在水深小于400米的海域无定义。屏幕色彩显示或印刷复刻的差异可能会影响对数据集所含内容的解读。
