GEMMS’ Expertise

The GEMMS 3D Coastal Ocean Model (GCOM3D) has gained wide acceptance since 1993 for accurate modelling of coastal ocean currents and tides. It has been used in studies including oil spill prediction, sediment plumes, storm surges, water quality and search and rescue.

The GEMMS Mesoscale Atmospheric Prediction System (MAPS) was the first high-resolution atmospheric model in Australia and has been used to simulate marine winds to support atmospheric pollution studies, for forecasting marine winds during America’s Cup challenges (1991 and 1995) and was the highest resolution model (1 km) used at the Sydney 2000 Olympics for marine forecasts for sailing and rowing.

Marine data measured by GEMMS’ instrumentation is used to provide further understanding of the marine environment and to validate the numerical prediction models.

GEMMS applies this expertise to a wide range of marine issues. For example…..

  • Hydrodynamic Studies
  • Discharge and Spill Modelling
  • Wave Studies
  • Storm Surge, Tide and Coastal Flood Modelling
  • Tide and River Flood Modelling in Coastal River Systems
  • Real-time Search and Rescue Prediction
  • Atmospheric Circulation
  • Atmospheric Pollution Studies
  • Current Profiling
  • Wave Measurements
  • Installation of marine instrumentation for ports and coastal projects
