“…The evidence suggests that there has been little variation in hydroisostatic deformation along many thousands of kilometres of the Australian coast during the mid-to late Holocene. This is contrary to predictions of Nakada and Lambeck (1989) and Lambeck and Nakada (1990). There were not enough across-shelf samples to test model predictions for differential hydro-isostatic warping across the continental shelf (Chappell et al, 1982;Chappell, 1983).…”

“…Although more evidence is required, the Rottnest Island data is not so different as was previously thought (Playford, 1983) when compared with many other parts of Australia. Lambeck and Nakada (1990) found it difficult to explain the difference between the Rottnest Island data and an adjacent estuarine mid-Holocene sea-level elevation sample in terms of their transverse continental shelf isostatic model. As with many others, they speculated that there may have been local tectonic uplift at Rottnest Island or in southwest Australia generally (Semeniuk and Searle, 1986) to explain the discrepancy.…”

Haworth, R. J., Baker, R. G. V. and Flood, P. G. 2002. Predicted and observed Holocene sea-levels on the Australian coast: what do they indicate about hydro-isostatic models in far-field sites?.ABSTRACT: Data relating to Holocene sea-level elevations and ages, obtained by radiocarbon dating of relict calcareous skeletons of intertidal organisms from widely spaced parts of the Australian coast, a far-field region of comparative tectonic stability, are divisible into two sets, namely: pre-and post-ca. 3600 yr BP. The older ages are from material consistently between 1.5 m and 2.2 m higher than present sea-level, whereas the younger ages (ca. 3600-1500 yr BP) generally cluster around 1 m above present sea-level. The elevations do not display any decline in amplitude from north to south over an extensive transect, contrary to predictions by hydro-isostatic models. Also, there appears to be little difference between time-elevation results for the coasts of North Queensland, New South Wales and the Bass Strait region adjacent to Tasmania, despite differences in the width of the continental shelf in these three locations, and the expectation of some hydro-isostatic warping of the continental shelf subsequent to the onset of the Holocene transgression. Results from the south and southwest coasts of Western Australia also display similar elevations to the east coast for the same time periods. There is sufficient evidence extending over 20°of latitude to suggest that north-south differences related to hydro-isostatic influence is limited or non-existent. There is insufficient data to test hydro-isostatic models across continental shelves. Hydro-isostasy, and the lithological elasticity it reflects, may not be as pronounced in far-field sites with narrow continental shelves as models predict. Stable far-field passive continental margins may be the best place to measure the ratio of inputs of eustatic and hydro-isostatic influences on Holocene relative sea-levels.

“…Thus if there has been a substantial reduction in Antarctic volume some north -south dependence in the sea -level signal can be expected (Nakada and Lambeck 1988 ). This is because there will be a long -wavelength signal emanating from Antarctica in which southern Australian Holocene highstands are reduced relative to those in the north, as is indeed suggested by the fragmentary evidence from both New Zealand and eastern Australia (Lambeck and Nakada 1990 ). Generally the available evidence from the southern latitudes is less satisfactory: evidence for Holocene highstands does occur along part of the coast (Belperio et al 2002 ) but there is no coral record and the indicators are from sources that are less securely related to mean sea level.…”

“…evidence for oscillations exceeding the observational noise level of approximately 0.25 m. It has been common practice to combine microatoll data from different sites across the Great Barrier Reef into a single sea -level record but this ignores the spatial variability that is created mainly by the hydro -isostatic response. For example the amplitude of the mid -Holocene highstand is predicted to vary by approximately 1.5 m across the reef with coastal highstands higher than offshore island highstands (Nakada and Lambeck 1989 ;Lambeck and Nakada 1990 ).…”

The level of the sea does not remain constant. It changes at varying rates, geographically and over time. Changes of sea level have affected human civilizations in the past (as preserved in legends, such as that of Atlantis), and anticipated accelerated sea -level rise as a consequence of enhanced global warming (Church et al. 2001 ;Bindoff et al. 2007 ) seems certain to have serious ramifi cations in the future.Understanding past sea -level change plays an important role in determining the underlying causes, and also permits the extrapolation of past sea levels to locations and epochs for which there are no instrumental data. In addition, the Earth has a memory of past events, and the pattern of relative sea -level change, today and in the future, will continue to respond to past events. This occurs for several reasons, including crustal response to past glacial retreats and re -advances, coastal subsidence from past sediment deposition, from present tectonic upheavals the underlying processes of which have their origins in the remote past, and from

“…These data reflect the far-field setting of the region, which is unaffected by glacial isostasy. Therefore, any changes in sea level here reflect eustatic or minor (1-2 m) hydroisostatic adjustments (Lambeck and Nakada, 1990;Lambeck et al, 2014).…”
