Post-glacial sea-level changes around the Australian margin: a review
It has been known since Rhodes Fairbridge’s first attempt to establish a global pattern of Holocene sealevel change by combining evidence from Western Australia and from sites in the northern hemisphere that the details of sea-level history since the Last Glacial Maximum vary considerably across the globe. The Australian region is relatively stable tectonically and is situated in the ‘far-field...
متن کاملSome Notes on Sea-level Change around the Australian Coastline
A proper understanding of the risk associated with sea-level change can only be attained by adherence to accurate terminology. In particular, it is vital to recognize the distinction between changes in eustatic sea-level, which correspond to changes in a notional world-wide average, and changes in local relative sea-level (LRSL), which correspond to changes in actual sea-levels at real and part...
متن کاملPresent - to - future sea level changes : The Australian case
We revisit available tide gauge data along the coasts of Australia, and we are able to demonstrate that the rate may vary between 0.1 and 1.5 mm/ year, and that there is an absence of acceleration over the last decades. With a database of 16 stations covering only the last 17 years, the National Tidal Centre claims that sea level is rising at a rate of 5.4 mm/year. We here analyse partly longer...
متن کاملClosing the sea level budget at the Last Glacial Maximum.
Establishing the volume of excess ice contained in the global ice sheets during the Last Glacial Maximum (LGM; ∼26,000–19,000 y ago) remains a longstanding problem in Ice Age climate dynamics. Expressed as the equivalent lowering of global mean sea level (GMSL), estimates of this value have varied from 105 (1) to 163 m (2), with many estimates suggesting ∼120 m (3). This wide range introduces s...
متن کاملSea level change through the last glacial cycle.
Sea level change during the Quaternary is primarily a consequence of the cyclic growth and decay of ice sheets, resulting in a complex spatial and temporal pattern. Observations of this variability provide constraints on the timing, rates, and magnitudes of the changes in ice mass during a glacial cycle, as well as more limited information on the distribution of ice between the major ice sheets...
