Data Source & Notes

Observed nutrient data are sourced from the Cockburn Sound Management Council (CSMC) routine monitoring program, supplemented by targeted campaigns from the WWMSP projects. The CS Region aggregate polygon encompasses all sub-zones within Cockburn Sound and provides a broad overview of model performance. Individual sub-zone comparisons are available via the MARVL Viewer.
