Dive into the dynamic coastal zone between land and sea

The DEA Intertidal product suite provides annual continental-scale elevation and exposure product layers for Australia’s exposed intertidal zone, mapped at a 10 m resolution from DEA’s archive of open-source Landsat and Sentinel-2 satellite data.

Supports coastal managers assess coastal impacts from extreme weather and inundation events, and shed light on historical erosion and sediment movements

Maps and models the ever-changing habitats of coastal fauna that inhabit the strand between terrestrial and marine environments

Why monitor the dynamic intertidal zone?

  • Use as baseline elevation data to assist coastal hazard impact assessment from extreme weather and inundation events
  • Investigate coastal erosion and sediment transport processes
  • Support habitat mapping and migratory species modelling for coastal ecosystems extending across the terrestrial to marine boundary
  • Integrate with existing topographic and bathymetric data to seamlessly map the elevation of the coastal zone
