SHOC is based on the nonlinear three-dimensional equations for momentum conservation, continuity, and the conservation of heat and salt. The model domain consists of the continental shelf and slope off eastern Tasmania. The domain was defined by a curvilinear horizontal grid with three open boundaries and the fourth side bounded by the Tasmanian coast. The seaward boundary ran parallel to the continental shelf break roughly following the 2500 m isobath. The two cross-shelf boundaries ran perpendicular to the shelf break and met the coast at South Cape in the south and just north of Eddystone Point in the north. The grid included two narrow spurs for the Derwent River and Huon River estuaries. River runoff was included by specifying the flow rate and temperature of freshwater input (zero salinity) every six hours at source points. The model boundary forcing consisted of daily fields of three-dimensional velocities, sea level, temperature and salinity from the 1/10-degree Bluelink ReANalysis (BRAN, version 3, 1/1/1993-31/7/2012) and OceanMAPS analysis (versions 2.0--3.1, 1/8/2012-31/12/2016). The model surface boundary forcing consisted of 6-hourly atmospheric fields provided by the National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR, 1993-2010) and Climate Forecast System Version 2 analysis (CSFv2, 2011-2016). Daily fields of sea surface height and three-dimensional fields of velocity, temperature, and salinity, were output every day.
