Determining Geoheritage Values, Figure 4 Assessment of the level of geoheritage significance (based on the approach described
by Brocx and Semeniuk 2007 but modified to focus on estuaries and deltas). The examples used to illustrate nationally significant
geoheritage features are ria coasts of Tasmania, New South Wales, and Northern Territory (from Australia) and shown in their global
context. The examples used to illustrate statewide/regional significance are barred estuaries (>5 km in size), drawn from Australia
and shown in a comparative global and national context. The examples used to illustrate local significance are flood-tidal deltas from
barred estuaries of southeastern Australia shown in a context of barred estuaries in Australia (See also “Geoheritage”).
