Abstract
-
We present new high-resolution seabed mapping of the shoreface to inner-continental shelf in New South Wales, Australia. The data combines a state-wide airborne LiDAR survey and vessel-based mapping, with seamless coverage from the terrestrial coast to 60 m water depth in selected sediment compartments. We explore some benefits of the new data for coastal management by comparing future shoreline change forecasts based on regional-scale and detailed seabed data.
