Bathymetry derived topographic rugosity grid

The grid was created from the Australian bathymetry and topography grid (2009, version 4). The data represents seabed rugosity of an area of seabed (a rectangle of 3 by 3 cells). The rugosity was measured as surface area (Jenness, 2004). Higher surface area corresponds with higher rugosity. Jenness, J. S. (2004).
