Dynamic height of sea surface height and currents referenced to 2000m, computed from CARS2000 3-dimensional seasonal temperature and salinity fields. Monthly values derived from annual and semi-annual temperature and salinity cycles. 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 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. All known reliable published data is used, but this is still very sparse in the SW, at depth, and especially for some nutrients. In many places strong interannual signals (which in many cases we do not attempt to resolve nor compensate for) may be aliased into spatial or seasonal signals.
