Sedimentary features and sediment transport pathways on the southeast Australian shoreface-inner continental shelf.

We present new observations and analysis of sedimentary features, including bedforms, on the shorefaceinner shelf of southeast Australia. Lidar coastal seabed mapping is classified and investigated to reveal the subtle morphology of sedimentary plains. Preliminary interpretations are made from feature morphology and distributions, past observations and global analogues. Our findings reveal new complexity across the dynamic shoreface-inner shelf and identify pathways and processes for along-shelf sediment transport and coast-shelf sediment connectivity. The observations highlight where repeat seabed mapping could reveal further insights on coastal sediment dynamics. Vessel-based seabed mapping and sampling currently in progress is essential for ground truthing interpretations and repeat mapping could reveal modes and rates of change over time.
