The Numerical Simulation Group on Engineering and Sciences (GSNCI), Technical University of Madrid (http://www.krios-hyperion.com/), a research group focused on ground-penetrating radar applications to glaciology, numerical modelling of glacier dynamics, and glacier mass balance studies, invites applications for a 2-yr postdoctoral position, with the details below.
Research theme: Three alternative themes are available:
· Numerical modelling of tidewater calving glacier dynamics integrated with regional climate modelling and mass balance modelling
· Rheological relationships for temperate ice – numerical modelling aspects
· Rheological relationships for temperate ice – ground penetrating radar aspects
Required background: ground-penetrating radar and/or numerical modelling and/or regional climate modelling and/or mass balance modelling
Numerical modelling of tidewater calving glacier dynamics integrated with regional climate modelling and mass balance modelling:
The focus of the project is the numerical modelling of the dynamics of tidewater glaciers, using a full-Stokes model incorporating a crevasse-penetration-depth calving law (though other types of calving laws could be considered). It is known that water filling the crevasses contributes to deepen the crevasses, and thus favours calving. As most of this water stems from surface melting, modelling of melt at the glacier surface can provide valuable information about the amount of available water. In turn, the modelling of melt strongly depends on the available meteorological data. Since the data available from in-situ automatic weather stations (AWS) or neighbouring manned meteorological station is usually scarce, it is planned to use regional climate modelling to provide detailed meteorological fields. In particular, the Weather Research & Forecasting (WRF) model will be used.
This is a co-operative project that will be carried out by our research group in collaboration with Prof. Dieter Scherer, from the Technical University o Berlin, and Prof. Christoph Schneider and Dr. Marco Möller, from the University of Aachen. Short periods of stay in Germany along the project are expected.
Rheological relationships for temperate ice:
The goal of the project is to improve the description of the rheology of temperate ice and its implementation into numerical models of glacier dynamics. Numerical and theoretical challenges to face range from adequate meshes for incorporating temperate ice bodies into a polythermal environment at low cost, the incorporation of the enthalpy balance equation, as well as boundary conditions for the enthalpy balance equation to a new constitutive relation, specifically a new rate factor, for temperate ice. Observational aspects are focussed on the large-scale estimation of the water content of temperate ice bodies, as well as the spatial and temporal scale of its variation. This involves the determination of the water content of temperate ice from the velocity of the radar wave, which depends on the permittivity of a three-component mixture of ice, air and water.
This is a co-operative project that will be carried out by our research group in collaboration with Prof. Angelika Humbert and Dr. Martin Rückamp, from the Alfred Wegener Institute/University of Hamburg. Short periods of stay in Germany along the project are expected.
Suitable expertise and skills
Candidates should have research experience and hold a Ph.D. related to glaciology, geophysics or a closely related branch of Physics, Mathematics or Earth Sciences. It is not necessary that the candidate holds the PhD at application time, provided that she/he has scheduled the PhD defence before the start of the postdoc contract.
The candidate is expected to provide her/his expertise in at least one of the main research fields involved (numerical modelling, ground-penetrating radar –including radar data processing–, regional climate modelling and mass balance modelling), though a combination of skills in any of these fields would be most valued. GIS and remote sensing skills will also be valued. Skills in publishing in international scientific journals are expected.
The successful applicant will have the opportunity to participate in polar fieldwork.
The salary will be according to the B2 contract category of the Technical University of Madrid (27,170.40 Euro/year gross salary) during the first year of contract, and B1 category (28,359.00 Euro/year gross salary) during the second half year. This is a typical postdoc salary in Spain, where the cost of living is lower as compared to most western and northern European countries. Typical personal tax income + social security deductions for such salary levels is or the order of 25%.
Further inquiries about the position may be directed to the leader of the research group, Dr. Francisco Navarro, e-mail: [hidden email], phone: +34 914533565.
The application deadline is 30th September 2012, though earlier applications are strongly encouraged. The application should be sent by e-mail to [hidden email], stating ‘Application to Postdoc position’ in the subject field. The application should include a CV, a publication list, details of the relevant qualifications and experience, and names and contact data of two persons who may act as reference.
The starting date of the contract should be, in principle, between 1st October 2012 and 1st January 2013. However, if a suitable candidate is found at an earlier time, an earlier starting date could be negotiated.
