eReefs GBR1 Diuron Dispersal: Great Barrier Reef Pesticide Model 2016-2018

Great Barrier Reef marine waters contain simulated dispersal data for the pesticide diuron from January 2016 to July 2018. The dataset was generated using a 1 km resolution eReefs hydrodynamic model forced by wind, tides, and other fluxes, and a transport model that disperses diuron from 16 river inputs. The model, developed by the Australian Ocean Data Network, incorporates a determined diuron half-life of 40 days and compares simulated distributions with observations at 11 monitoring sites.
