CSIRO Coastal Modelling Products (eReefs)

Updated: 2019-05-17

The marine modelling component of eReefs was tasked to deliver numerical models capable of simulating and predicting the physical hydrodynamic state, sediment transport, water quality and basal ecology of the Great Barrier Reef (GBR) lagoon and reef matrix. Together, these models represent a capability to simulate the transport and fate of waterborne material, of either oceanic or terrestrial origin, and its impact on Reef water quality. The numerical models are built using CSIRO’s Environmental Modelling Suite, and include regional 4 km and 1 km resolution models. The 4 km resolution model (GBR4 regional model) is intended to simulate the dominant oceanographic processes impacting on the GBR shelf and simulation results are available from December 2010 onwards. The 4 km grid (GBR4) has 180 x 600 cells, including 44 vertical layers with 1 m resolution at the surface. The 1 km resolution model (GBR1 shelf model) is nested within the 4 km model (GBR4) and began routine operation in December 2014. The 1 km grid (GBR1) is extremely large, with 510 x 2390 cells, including 48 vertical layers with 1 m resolution at the surface. The GBR4 and GBR1 results datasets are CF 1.0 compliant.
