About: The research of the Geodynamics Group at the Research School of Earth Sciences, is focused on using space-based observations to study changes on Earth. With strong backgrounds in geodesy, the researchers in the group are studying a wide range of topics including crustal deformation (tectonic drift, earthquakes) and glacial isostatic adjustment, as well as climate-related topics such as sea level rise and melting of polar ice sheets. Space-geodetic missions such as satellite altimeters (Jason-2, Envisat, IceSAT), space gravity (GRACE), and positioning systems (e.g. GPS) provide the observations for these studies. The research involves generating numerical models and processing the data such that estimates of these geophysical signals can be made.
Intern responsibilities: The IIP intern will work as part of a team to study some aspect of change on Earth using space-geodetic observations. There are many possible projects from which to choose: improving the modelling of satellite orbits, estimating changes in groundwater aquifers, quantifying crustal strain across continents and/or known active fault zones, deriving estimates of regional sea level rise, or measuring actual melting rates of polar regions, among others. Possible responsibilities may include developing software to model satellite orbits, processing actual satellite observations to derive estimates of geophysical processes on Earth, and/or developing and assessing different types of models for certain processes. The work is computationally intensive and the IIP intern could be involved in writing software, processing data, deriving estimates, and interpreting and evaluating the results. Previous IIP interns have worked on projects that have been submitted for publication with the intern as a co-author.
Qualifications: IIP candidates with interest in math, physics, earth science, computer science, earth physics, and/or geodynamics are encouraged to apply. Basic knowledge of Linux or Unix operation systems and programming ability would be an asset but are not required. French would also be an asset but is not required.
Previous work responsibilities (in the words of a past intern): Intern #1: I rewrote their program to make it much more flexible, powerful and easy to work with. The project itself involved using and analyzing data from the GRACE satellite mission. I worked with Matlab a lot, so I learned quite a bit of this. I also did Monte Carlo simulations, which was very interesting. The organization was trying to find an accurate representation of the earth deformation using the data from an old satellite system called Grace. They're trying to estimate these Love Numbers in order to match the displacements collected by GPS data. If the research makes more progress, they plan on publishing a paper on their findings. Intern #2: My project was to perform inversions with the equation used to calculate earth deformation due to surface loading. I interpreted the data collected from satellites at various locations and inverted to estimate coefficients called Love Numbers. Most of my work was on Matlab and/or Fortran...
