TITLE : Sediment density from CT scan analysis

The goal of this project is to establish a calibration between CT scan and sediment density measurements using conventional approaches. This project will increase the spatial resolution of the characterization of sedimentary deposits to improve paleoclimatic and paleoenvironmental 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 INRAE, France (Dr. J-P Jenny). The project will benefit from state-of-the-art research infrastructure (, and assistance from the laboratory’s technical team.

EXPECTED STARTING DATE : From September 2021

Supervisor: Pierre Francus (INRS) Co-supervisor: Dr Jean-Philippe Jenny (INRAE, France)
