Changes in seagrass coverage in Cockburn Sound in 1967 were assessed from aerial photographs using modern mapping methods with the aim of accurately determining the magnitude of change in hectares of seagrasses.
-
Changes in seagrass coverage in Cockburn Sound 1972 were assessed from aerial photographs using modern mapping methods with the aim of accurately determining the magnitude of change in hectares of seagrasses.
-
Changes in seagrass coverage in Cockburn Sound in 1995 were assessed from aerial photographs using modern mapping methods with the aim of accurately determining the magnitude of change in hectares of seagrasses between 1967 and 1999.

This mapped dataset is a compilation of spatially explicit, nation-wide threats to seagrass based on current pressures and projected future climate change pressures. In addition, the value of this mapped dataset can potentially extend to assess threats to other coastal habitats. Current threats in this mapped dataset include urban/agricultural runoff, industrial pollution, sediment resuspension, port infrastructure and dredging, shipping accidents, oil and gas accidents. Future threats in this mapped dataset include modelled increase in sea surface temperature for 2070, modelled increase in total annual rainfall for 2070 and modelled increase in sea level rise for 2070. All threats in this mapped dataset are given as a single ArcGIS polygon shapefile composed of 10 x 10 km coastal grid cells.
