eReefs GBR4 biogeochemistry and sediments v3.1 reduced loads catchment scenario
Results from version 3.1 of the the 4km-resolution biogeochemistry and sediments model of the Great Barrier Reef (GBR4), forced by version2 of the Hydrodynamic model and by a reduced-loads catchment scenario which is derived from SOURCE Catchments with 2019 catchment condition (q3b) with anthropogenic loads (q3b – q3p) reduced according to the percentage reductions of DIN, PN, PP and TSS specified in the Reef 2050 Water Quality Improvement Plan (WQIP) 2017-2022 as calculated in Brodie et al., (2017). Further, the reductions are adjusted to account for the cumulative reductions already achieved between 2014 and 2019 that will be reflected in the 2019 catchment condition used in q3b.
This model configuration and associated results dataset may be referred to as "GBR4_H2p0_B3p1_Cq3R_Dhnd" according to the eReefs biogeochemical simulation naming protocol. The model ran in hindcast-mode as one of a suite of simulations which included baseline (GBR4_H2p0_B3p1_Cq3b_Dhnd) and pre-industrial (GBR4_H2p0_B3p1_Cq3p_Dhnd) catchment scenarios.

- Supplemental Information
-
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. 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 product is CF 1.0 compliant.
