Geomorphic feature classification for Lord Howe Island and Balls Pyramid shelves
This dataset is a geomorphic classification of the shelf features surrounding Lord Howe Island and Balls Pyramid. This dataset provides information on the size, extent and type of features which occur around the shelves, which can be used for a broad range of marine planning and research purposes.
Shelves were classified into shelf region (inner, mid, outer) and geomorphic features. Features include an extensive submerged fossil reefs, ridges and patch reefs, sandy basins, paleochannels, modern fringing reef, shallow lagoon, shelf edge terraces and shelf break. Broad seafloor features were visually interpreted through digitisation in ArcGIS v10.1 using terminology consistent with international nomenclature and national standards. The classification of geomorphic features extends upon the interpretation of Balls Pyramid shelf undertaken by Linklater et al. (2015).

- Statement
- Broad seafloor features were visually interpreted through digitisation in ArcGIS v10.1 using terminology consistent with international nomenclature and national standards. Shelves were classified into shelf region (inner, mid, outer) and geomorphic features. The inner shelf represents the zone within approximately 1 km of the shoreline to around 30–35 m depth. Inner shelf features around Lord Howe Island were defined at a 1:6000 map scale using WV2 imagery, supplemented with ADS40 (2012) (Land and Property Information, New South Wales, Australia) aerial imagery where cloud artefacts obscured the view. The middle and outer shelf zones have varying distances from the shoreline, and typically represent the seaward 50 and 130 m isobaths, respectively. For the remaining shelf, features were digitised at 1:10,000 using slope transparently (50%) displayed over the bathymetry model. The large, mid-shelf fossil reef features were sub-divided into the upper (below 35 m depth), lower (beyond 35 m depth), and intra-reef depression (localised lows within reef structure) features.
