    Data gap notice

    Some dates in the 4km eReefs BioGeoChemical model v4.2 dataset have been removed because the model output for those dates was found to be inaccurate, as shown in this sample video.

    The following date ranges have been removed:

    Start date End date
    2 Jan 2011 31 Jan 2011
    2 Feb 2012 2 Mar 2012
    9 Mar 2013 7 Apr 2013
    1 Mar 2014 30 Mar 2014
    6 Apr 2015 5 May 2015
    10 May 2016 8 Jun 2016
    14 Jun 2017 13 Jul 2017
    19 Jul 2018 17 Aug 2018
    23 Aug 2019 21 Sep 2019

    Please use caution when interpreting the videos in the player above.

    Although the obviously inaccurate dates have been removed, the model may take some time to recover after each disruption. As a result, data in the days and weeks following the removed periods may also be affected. The 30-day buffer used here is a visual estimate and not scientifically validated, so some remaining inaccuracies may still be present in the dataset.

    We will update this portal when corrected model output becomes available.

    Dissolved Organic Carbon

    The concentration of carbon in dissolved organic compounds.

    Dissolved Organic Nitrogen

    The concentration of nitrogen in dissolved organic compounds.

    Dissolved Organic Phosphorus

    The concentration of phosphorus in dissolved organic compounds.

    Source data

    The videos/images on this page are based on the 4km eReefs BioGeoChemical model (v4.2) run with SOURCE Catchments using Baseline catchment conditions. The model builds on the CSIRO Environmental Modelling Suite (EMS), described in the paper: Scientific description of the optical and biogeochemical models (vB3p0). The dataset metadata is available from the NCI GeoNetwork: eReefs GBR4 Biogeochemistry and Sediments v4.2 baseline catchment scenario. The raw model data is available from the NCI THREDDS server (daily, in curvilinear 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 runoff used to drive the BGC model was provided by the SOURCE Catchments modelling.
