Postdoctoral position in ice dynamics and radar analysis at ULB

Frank Pattyn
Postdoctoral position – Ice Dynamics derived from englacial Radar reflection
Architecture (IDyRA)
Laboratoire de Glaciologie, Université Libre de Bruxelles (ULB)

The Laboratoire de Glaciologie of the Universté Libre de Bruxelles (ULB) is
currently seeking to fill a 4-years postdoctoral position in ice sheet
modelling and radar data analysis. The work is a part of a FNRS-FRFC
research project entitled IDyRA, sponsored by the French Community of
Belgium and in collaboration with the Norwegian Polar Institute (Tromsø,

IDyRA (Ice Dynamics derived from englacial Radar reflection Architecture)
aims at improving our knowledge of the interaction between the ice sheet and
the ice shelf (Antarctic grounding zones). It specifically aims at
understanding the processes of subglacial melting and basal sliding by
combining englacial information obtained from radio-echo sounding surveys
with state-of-the-art higher-order ice sheet models. More specifically,
IDyRA will improve the understanding of the role of buttressing in east
Dronning Maud Land, Antarctica, where the marine ice sheet is buttressed by
numerous ice rises. Results of the project will contribute to a quantitative
interpretation of melting under the ice shelf, its effect on ice sheet
behaviour and the effect of a thermohaline circulation under the ice shelf.
Furthermore, the stability of ice rises will be investigated through an
analysis of the so-called Raymond effect. Most radar data have been
collected (or are in the process of collection) within the framework of
existing research projects, such as BELISSIMA (Belgian Ice Sheet – Shelf Ice
Measurements in Antarctica) and through EUFAR (European Facility for
Airborne Research).

The successful candidate will contribute to the development/application of
thermomechanically coupled higher-order models which solve various
approximations of the Stokes system and use them to simulate englacial radar
reflectors (isochrones).  Depending on the previous experiences of the
successful candidate, it is also expected to contribute analysis of the
radar data, developing new analytical algorithms to precisely estimate
englacial radar attenuation and bed reflectivity (using modelled temperature
fields).  It is one of our ultimate goals to interpret both englacial
reflector patterns and radar returned power from within and beneath the ice
using the suite of these new tools.  It is also possible to be involved in a
future ground-based field campaign in Antarctica. This work will be done in
close collaboration with Dr. Kenny Matsuoka of the Norwegian Polar Institute
in Tromsø.

Applicants should email a cover letter and Curriculum Vitae at the address
below. Review of the applications will begin 1 March and will continue until
the position is filled.

The desired qualifications are a PhD in glaciology, geophysics, or an
equivalent geoscience, with good programming skills in a C and Matlab
environment. We seek in the first place either a person with a background in
radar geophysics and a keen interest in ice sheet modelling or an ice sheet
modeller with a keen interest in radar geophysics. The position is for a
period of 4 years and will start as soon as possible.
