Narrabeen Profiles

The pre-2005 survey measurements (survey method ‘EMERY’ in column 5) were undertaken at a fixed cross-shore spacing of 10 m (no interpolation), while surveys undertaken after this time (survey method ‘GPS’) have been interpolated to a standard 1 m cross-shore spacing. Intermittent survey measurements in the stable dune areas of each profile have been carried through to the following survey date and are identified by the flag ‘DUNEFILL’ in column 5. Elevation is relative to Australian Height Datum (AHD), corresponding to approximately mean sea level. Lat/long are referenced to GRS80 Ellipsoid.
