Abstract

Geoscience Australia's GEOMACS model was utilised to produce hindcast hourly time series of bed shear stress on the Australian continental shelf on a 0.1 degree grid covering the period March 1997 to February 2008 (inclusive). The effective depth range of the model output is approximately 20 - 150 m (see 'Data Quality Attribute Accuracy' below). The hindcast data represents the combined contribution to the bed shear stress by waves, tides, wind and density-driven circulation. The stability of the seabed sediment surface, which is controlled by seabed shear stress, is likely to influence benthic community structure and species diversity. There are 8 grids in the dataset: geomacs_excee, geomacs_gmean, geomacs_qua25, geomacs_qua50, geomacs_qua75, geomacs_range, geomacs_ratio, and geomacs_tmean. Please see the metadata for further information.
