Brief description

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.
