|a A data archaeology exercise was carried out on sea level observations recorded
during the Transit of Venus across the Sun observed in 1874 from Saint-Paul
Island, 38°41’S - 77°31 E, in the Southern Indian Ocean. Historical (1874) and
recent (1994-2009) sea level observations were assembled into a consistent time
series. A thorough check of the data and its precise geodetic connection to the
same datum was only possible thanks to the recent installation of new
technologies (GPS buoy and radar water level sensor) and levelling campaigns.
The estimated rate of relative sea level change, spanning the last 135 years at
Saint-Paul, was not significantly different from zero (-0.1 ± 0.3 mm/yr), a value
which could be reconciled with estimates of global average sea level rise for the
twentieth century assuming the DORIS vertical velocity estimate at Amsterdam
Island (100 km distant) could be applied to correct for the land motion at the tide
gauge. Considering the scarcity of long-term sea level data in the Southern
Hemisphere, the exercise provides an invaluable additional observational
constraint for further investigations of the spatial variability of sea level change,
once vertical land rates can be determined. |
