PhD position in ice sheet elevation and elevation change from radar
altimetry observations at the School of GeoSciences, Edinburgh, UK

The candidate will work on radar altimetry measurements over the
Greenland and Antarctic Ice Sheets. The position is funded through the
European Space Agency project CryoTop Evolution (Space-borne
observations for mapping fine elevation and elevation change over Ice
Sheets). The thesis will consist in processing and analysing CryoSat-2
radar altimeter datasets with the objectives of improving the spatial
and temporal resolution of elevation and time varying elevation to
better quantify changes affecting the Greenland and Antarctic ice
sheets. The working environment at Edinburgh
(<>) and within the project’s
consortium provides excellent opportunities for learning and
collaboration in the fields of remote sensing, field observations, and
numerical modeling of polar research.

Climate warming over the 20th century has caused drastic
changes in the Greenland and Antarctic Ice Sheets (GrIS, AIS) which in
turns is impacting rates of sea level change. Observation from Satellite
altimetry is a powerful approach to quantify changes in the Ice Sheet
mass and to investigate the processes that link the Cryosphere,
Atmosphere and the Ocean. Reference and repeat-observations of Ice Sheet
topography is critical to quantify changes in ice thickness, provide
estimates of ice mass change and contribution of the cryosphere to sea
level change. Retrieving ice elevation present significant challenges as
many regions require very fine spatial resolution. An estimated of ~50 &
~75 % of Antarctic and Greenland ice sheet mass losses are within 100 km
of coast, but <10 % of these regions are surveyed by conventional
altimetry because of sparse ground tracks and coarse resolution
footprints failing due to high slopes. Radar altimetry mission CryoSat
provides a step change in our ability to map the coastal region of the
GrIS and AIS thanks to its tighter ground track distribution and its SAR
interferometry mode enabling high-resolution elevation mapping.

The following work is envisaged:

• Analyses of CryoSat-2 dataset to generate surface elevation and
elevation change over the GrIS and AIS.

• Propose and implement strategies to enhance the above products.

• Analyse the findings and contribution to sea level change

You must have a degree in geophysics, meteorology,
physics, or comparable science. Experience in scientific programming,
analysis of remote sensing, and good English skills (spoken and written)
are expected. Basic knowledge of polar processes (land ice, ocean,
atmosphere) is of advantage.

Application deadline is 22 April 2016. Please direct enquiries about the
post and send application material (CV, copies of transcript of records
of BSc/MSc, contact information of references) to: <>
