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.
