Mapset: Sea Surface Height Quarterly Means ( in the Australian Region)

Set of four maps of mean sea surface height 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. It covers the region 100-200E, 50-0S, on a 0.5 degree grid, and on 56 standard depth levels. Higher resolution versions are also available for the Australian continental shelf. 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.

本数据集包含4张平均海平面高度图，其数据源自存储于CARS2000中的年周期与半年周期温度和盐度循环数据。CARS是一套温度、盐度、溶解氧、硝酸盐、磷酸盐以及硅酸盐的季节分布图集，基于所有可用海洋学数据，采用Loess映射法生成。该数据集覆盖东经100°至200°、南纬50°至0°的海域，采用0.5°×0.5°的网格分辨率，并包含56个标准深度层的数据。针对澳大利亚大陆架区域，还提供了更高分辨率的数据集版本。本数据集的原始数据取自《世界海洋图集1998》（World Ocean Atlas 98）以及CSIRO海洋与NIWA的档案库。该数据集旨在针对澳大利亚海域改进莱维图斯WOA98图集的相关表现。这些海图由CSIRO为国家海洋办公室制作，作为其通过‘国家海洋生物区划（National Marine Bioregionalisation）’项目推进自然资源规划与管理的长期工作的一部分。水深不足400米的区域不适用平均海平面高度数据。
