"The Effect of Surface Loading of the Earth on GPS and Absolute
Gravity Measurements of vertical crustal movements"
GPS and absolute gravity measurements are now being used to
measure the long term vertical crustal movements of the UK. These
movements are about 1 to 2 mm/year and are due to large scale
geophysical processes such as post-glacial rebound and also to
more local processes such as sediment compaction. However, in
order to determine these long term trends to the required accuracy
various other vertical displacements have to be removed from the
observations. These are due to deformation of the Earth due to
surface loading by the ocean tides (deformations up to 12cm in
range in the UK), by atmospheric pressure and ground water
variations and by non-tidal sea level variations. The research
will involve the use and improvement of existing ocean tide loading
computer models, using new ocean tide models and the extension
of the models to investigate the deformations of the Earth by these
other surface loads. The model results will be compared with both
continuous GPS and absolute gravity data.
The studentship is for 3 years and the student will work at the
Proudman Oceanographic Laboratory, Wirral and register for a PhD
with the Department of Earth Sciences, University of Liverpool.
A keen interest in computer modelling and the interpretation of
observational data is essential. A good first degree in geophysics,
geodesy, physics, mathematics or related physical sciences is
required. For further information contact Professor T. F. Baker,
