|a Mean sea level measurements made at Port Louis in the Falkland Islands in 1981–1982,
1984, and 2009, together with values from the nearby permanent tide gauge at Port Stanley,
have been compared to measurements made at Port Louis in 1842 by James Clark Ross.
The long‐term rate of change of sea level is estimated to have been +0.75 ± 0.35 mm/yr
between 1842 and the early 1980s, after correction for air pressure effects and for vertical
land movement due to glacial isostatic adjustment (GIA). The 2009 Port Louis data set
is of particular importance due to the availability of simultaneous information from Port
Stanley. The data set has been employed in two ways, by providing a short recent estimate
of mean sea level itself, and by enabling the effective combination of measurements at the
two sites. The rate of sea level rise observed since 1992, when the modern Stanley gauge
was installed, has been larger at 2.51 ± 0.58 mm/yr, after correction for air pressure and GIA.
This rate compares to a value of 2.79 ± 0.42 mm/yr obtained from satellite altimetry in
the region over the same period. Such a relatively recent acceleration in the rate of sea
level rise is consistent with findings from other locations in the Southern Hemisphere and
globally. |
