Phosphorus is a key nutrient required for organic growth. The main source of natural phosphorus is sedimentary rock.
Particulate Inorganic Phosphorus
Phosphorus ions that are absorbed onto particles. It is considered a particulate with the same properties as Mud.
Particulate Inorganic Phosphorus sediment
Phosphorus that is permanently removed from the system through burial of Particulate Inorganic Phosphorus in the sediment.
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 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 runoff used to drive the BGC model was provided by the SOURCE Catchments modelling.
