Fetch-based exposure indices for temperate Australia
These data describe quantitative exposure indices generated using cartographic fetch methods on a 0.01 degree grid across temperate Australia (South Australia, Victoria and Tasmania).
Two indices are reported: openness and bathymetry-altered fetch. Openness is a measure of the distance of a site to the nearest coastline in all directions and describes potential exposure to locally generated seas and undefined swell. Bathymetry-altered fetch attempts to account for the attenuation of wave energy as waves move into shallow waters and encounter friction with the seafloor.

- Purpose
- These indices were derived in there recognition that quantitative exposure indices for broad spatial scales in shallow waters (<30m) across temperate Australia were lacking. Quantitative measures were generated to facilitate work being conducted within the CERF Marine Biodiversity Hub.
- Credit
- Any users of CERF Marine Biodiversity Hub data are required to clearly acknowledge the source of the material in the format: "Data was sourced from the CERF Marine Biodiversity Hub – the Marine Biodiversity Hub is supported through funding from the Australian Government’s National Environmental Research Program (NERP), administered by the Department of Sustainability, Environment, Water, Population and Communities (DSEWPaC)." Also credit other authors and organisations involved in collection of this particular datastream (as listed in ‘cited responsible party’ in the metadata record).

- Statement
- Fetch-based exposure indices were generated using the Generic Relative Wave Exposure Model (GREMO) implemented within the ArcMap program in ArcGIS 9.3. A The GEODATA Coast 100K 2004 Australian Coastline (Geoscience Australia) and the Australian Bathymetry and Topography Grid (Whiteway 2009) that was supplemented with nearshore data collected by the SEA.MAP Tasmania project were used as input layers. A 0.01 degree grid was generated from the coast to the 30m depth contour and exposure indices were calculated for each grid point.
