Last Interglacial And Holocene Trends In Sea-Level Maxima Around Australia: Implications For Modern Rates, Edward A. Bryant
Last Interglacial And Holocene Trends In Sea-Level Maxima Around Australia: Implications For Modern Rates, Edward A. Bryant

This paper defines the spatial trend in sea-level around Australia at 3 timescales, namely at the time of the maximum of the last interglacial around 125000 yr BP, during the Holocene maximum between 5-6000 yr BP and over the last 20 years. Last interglacial elevations range from -2m around the Great Barrier Reef to +32m in northeast Tasmania. Trend surface analysis shows that over 77% of the noise in these sea-level elevations can be accounted for by a pattern evidencing tectonic uplift towards the southern edge of the continent. Assuming a eustatic sea-level at this time of +4 to 6m, …

Sand barriers along the coast of southern New South Wales, dating from the last interglacial, have been almost completely destroyed, most probably by a catastrophic tsunami. Evidence for catastrophic wave erosion can also be traced to heights of at least 15 m above present sea level on coastal abrasion ramps. These erosional features lie above the range of effective erosion by contemporary storm waves, and cannot be attributed to either eustatic fluctuations or local uplift. Chronological evidence for the timing of the destruction of the last interglacial barriers suggests that tsunami generated by the submarine slide off Lanai in the …

In the coastal region, the highest magnitude storms cannot always be invoked to account for large-scale, anomalous sediment features. Any coastline in the Pacific Ocean region can be affected by tsunamis, including Australia which historically lacks evidence of such events. Geologically, tsunamis along the New South Wales coast have deposited a suite of Holocene features that consist of anomalous boulder masses, either chaotically tossed onto rock platforms and backshores or jammed into crevices; highly bimodal mixtures of sand and boulders; and dump deposits consisting of well sorted coarse debris. In addition many coastal aboriginal middens were disturbed by such events. …
