Master's Project : Sediment density from CT-scan analyses

Institut national de la recherche scientifique (INRS)
INRS

The goal of this project is to establish a calibration between CT-scan and sediment density measurements from conventional approaches. This project will increase the spatial resolution of the characterization of sedimentary deposits to improve paleo-climatic and paleo-environmental reconstructions.

The specific objectives of the student will be:

1. use data from more than 400 cores from various parts of the world
2. develop an algorithm for correcting the 3D images acquired to take into account the volumes actually occupied by the sediment in the cores
3. validate the results with a set of density measurements acquired by other methods
4. establish the number and type of density measurements on discrete samples to obtain a robust calibration
5. compare the results obtained by the medical CT-scan with those of a micro-CT-scanner

This project is part of the Canada Research Chair in Environmental Sedimentology, and a collaboration with INRA, France. The project will benefit from state-of-the-art research infrastructure (ctscan.ete.inrs.ca), and assistance from the laboratory's technical team.

Research assistant in forest ecology in the taiga of northern Quebec

UQAR
Taiga of northern Quebec

We are looking for undergraduate students to assist us in our field work in the taiga of Quebec in the summer of 2020. We will work on two different projects aimed at: 1- reconstructing the climate of the last 2000 years from dark circles annual growth of preserved trees in lakes; 2- measure post-fire regeneration and the state of the forest in a monitoring device for the boreal forest forming a 100 km transect.
