Coastal storms have been considered significant agents in transporting sediment, modifying morphology and causing recent beach erosion. Along the New South Wales coast, the concomitance of storms, warmer sea surface temperatures and poleward movement of the Hadley cell was linked to beach erosion on Stanwell Park beach between 1943 and 1978. This result was defined using an accurately constructed compilation of coastal storms and a precisely measured time series of high tide positions taken from 105 oblique photographs. The two data sets are amongst the best of their kind in the world. Indices of storm magnitude, representing cumulative significant wave …

The recent detailed analyses by Aubrey and Emery (1986) of Australian sea level trends continues their efforts to define tectonic and climatic factors worldwide that dominate long- and short-term fluctuations respectively in sea level records. These factors have included sediment and water loading on the adjacent shelf, the tectonic behaviour of plates, fluctuations in the Southern Oscillation, behaviour of currents impinging on the shelf, and river runoff. We do not object to these efforts; however we are disturbed by misrepresentations in their recent paper on Australian sea levels regarding (1) the interpretation of the nature of sea-level records, (2) the …
Sea-Level Variability And Its Impact Within The Greenhouse Scenario, Edward A. Bryant
Sea-Level Variability And Its Impact Within The Greenhouse Scenario, Edward A. Bryant
Faculty of Science - Papers (Archive)
The greenhouse scenario assumes that sea level will rise worldwide at uniform rates because of near-polar ice melting or because of thermal expansion of ocean waters. This view ignores the natural variability of existing sea-level behaviour that occurs globally over time. It also ignores the fact that some of this variability is related to changes in climatic parameters such as precipitation, barometric pressure and temperature that will be influenced by the greenhouse effect. This paper presents existing evidence on sea-level variability across the globe and links it to changes in atmospheric pressure, air temperature and precipitation for the period 1933-1980. …
