Total Chlorophyll
Sum of chlorophyll concentration of the four microalgae types (small, large, microphytobenthos, trichodesmium).
Dissolved inorganic nitrogen
Concentration of dissolved inorganic nitrogen (DIN). DIN = [NH4] + [NO3].
Total suspended solids
This is the sum of the suspended sediments in the water column. It is [Fine sediment] + [Mud] + [Mud carbonate] + [Mud mineral] + [Dust]
Source data
The videos/images on this page are based on the 4km eReefs BioGeoChemical model (v3.1) (GBR4_H2p0_B3p1_Cq3b_Dhnd) run with SOURCE Catchments using Baseline catchment conditions. Detailed information about the model can be found in the paper: CSIRO Environmental Modelling Suite (EMS): Scientific description of the optical and biogeochemical models (vB3p0). The raw model data is available from the NCI THREDDS server (daily, in curvilinear NetCDF format) and the aggregate data from the AIMS eReefs THREDDS server (daily, monthly, yearly, in in regular rectangular grid NetCDF format).
Data span
These results are based on a fixed time period (Dec 2010 - Apr 2019) hind-cast analysis developed for comparing changes in land practices. The river run off used to drive the BGC model were provided by the SOURCE Catchments modelling.
