|a As an island nation with some 85% of the population residing within 50 km of the coast, Australia faces significant
threats into the future from sea level rise. Further, with over 710,000 addresses within 3 km of the coast and below 6-m
elevation, the implication of a projected global rise in mean sea level of up to 100 cm over the 21st century will have
profound economic, social, environmental, and planning consequences. In this context, it is becoming increasingly
important to monitor trends emerging from local (regional) records to augment global average measurements and future
projections. The Australasian region has four very long, continuous tide gauge records, at Fremantle (1897), Auckland
(1903), Fort Denison (1914), and Newcastle (1925), which are invaluable for considering whether there is evidence that
the rise in mean sea level is accelerating over the longer term at these locations in line with various global average sea
level time-series reconstructions. These long records have been converted to relative 20-year moving average water level
time series and fitted to second-order polynomial functions to consider trends of acceleration in mean sea level over time.
The analysis reveals a consistent trend of weak deceleration at each of these gauge sites throughout Australasia over the
period from 1940 to 2000. Short period trends of acceleration in mean sea level after 1990 are evident at each site,
although these are not abnormal or higher than other short-term rates measured throughout the historical record. |
