Temperature changes during a similar period and possibly responsible for causing the observed sea level rise.
Sea level variations over the last nine thousand years
This figure shows the change in annually averaged sea level at 23 geologically stable tide gauge sites with long-term records as selected by Douglas (1997). The thick dark line is a three-year moving average of the instrumental records. These data indicate a sea level rise of ~27.5 cm from 1800-2000. Because of the limited geographic coverage of these records, it is not obvious whether the apparent decadal fluctuations represent true variations in global sea level or merely variations across regions that are not resolved.
For comparison, the recent annually averaged satellite altimetry data [1] from TOPEX/Poseidon are shown in red. These data indicate a somewhat higher rate of increase than tide gauge data, however the source of this discrepancy is not obvious. It may represent systematic error in the satellite record and/or incomplete geographic sampling in the tide gauge record. The month to month scatter on the satellite measurements is roughly the thickness of the plotted red curve.
Data
Original data for this figure are from the Permanent Service for Mean Sea Level [2] (PSMSL). Douglas (1997), defined the following criteria for selecting records from the PSMSL which were long, reliable, and avoided large vertical geologic changes:
Each record should be at least 60 years in length
Not be located at collisional plate boundaries
At least 80% complete
Show reasonable agreement at low frequencies with nearby gauges sampling the same water mass
Not be located in regions subject to large post-glacial rebound
He subsequently identified 24 PSMSL records meeting all five of these criteria:
Auckland, 1903-2000
Balboa, 1908-1996
Brest, 1807-2000
Buenos Aires, Argentina, 1905-1987
Cascais, 1882-1993
Cristobal, 1909-1980
Dunedin, 1900-1998
Fernandina, 1897-2003
Genova, 1884-1997
Honolulu, 1905-2003
Key West, 1913-2003
Lagos, 1908-1999
La Jolla, 1924-2003
Lyttelton, 1924-2000
Marseille, 1885-2000
Newlyn, Cornwall, 1915-2003
Pensacola, 1923-2003
Quequen, 1918-1982
San Diego, 1906-2003
San Francisco, 1854-2003
Santa Cruz de Tenerife, 1927-1990
Santa Monica, 1933-2003
Trieste, 1905-2001
Wellington, 1901-1988
After slight corrections following Douglas (1997) for any remaining post-glacial rebound at these sites (typically ~3 cm/century), the tide gauge data from these sites were plotted in no particular order as the thin lines in the above figure. One site, Wellington, was omitted because the author of this figure was unable to locate the corresponding record from the PSMSL.
