Sea Level at Port Arthur, Tasmania
Hunter, J., Coleman, R. and Pugh, D. 2003. The sea level at Port Arthur, Tasmania, from 1841 to the present. Geophysical Research Letters 30: 10.1029/2002GL016813.
The full set of data indicated an average rate of sea level rise, relative to the land, of 0.8 ± 0.2 mm/year over the period 1841 to 2002, which yields, in their words, "an estimate of average sea level rise due to an increase in the volume of the oceans of 1.0 ± 0.3 mm/year, over the same period."
In considering these findings, the three researchers say their results may be compared with recent estimates for the two longest (continuous) Australian records of Fremantle and Fort Denison of 1.6 and 1.2 mm/year, respectively, after glacial isostatic adjustment, citing Lambeck (2002). Noting that "historic and modern records from Port Arthur, Tasmania, cover the longest time span of any sea level observations in the Southern Hemisphere and are related to a single benchmark," they say "they provide a significant contribution to our knowledge of past sea level rise in this data-sparse region." And part of that significance must reside in their noting that their sea level rate-of-change results "are at the lower end of the recent estimate by the Intergovernmental Panel on Climate Change on global average rise for the 20th century."
