Presentation of the structure

The Institute of Environmental Geosciences (IGE) is a public research laboratory under the joint supervision of the CNRS/INSU, IRD, Université Grenoble Alpes (UGA), and Grenoble INP.
It brings together approximately 240 people, including 145 permanent staff members (researchers, faculty members, and engineers) and around 95 PhD students, postdoctoral researchers, and fixed-term contract staff. The laboratory also hosts several dozen interns and visiting scientists each year. The laboratory is located across two sites on the Grenoble university campus (MCP, OSUG-B, and Glacio sites).
IGE is one of the main laboratories of the Grenoble Observatory of Earth and Universe Sciences (OSUG), a federative structure of the INSU.

You will be supervised by Florent Gimbert, a CNRS Research Scientist within the CryoDyn team. The overall objective of the CryoDyn team is to better understand and describe the processes that control ice dynamics, in order to better characterize and predict the evolution of glaciers, ice sheets, and sea ice.

Main missions

As part of the five-year Aria GRuMPS project, you will contribute to improving our understanding of the melting of the Greenland Ice Sheet and its impact on the climate.

Your objective: to develop an innovative method based on passive seismology to measure meltwater discharge, both beneath and downstream of glaciers. Measurements carried out on land-terminating glaciers will then be used to estimate the discharge of marine-terminating glaciers, which are difficult to observe directly.

A research project at the intersection of seismology, glaciology, and climate modelling, addressing key challenges related to current climate change.

Main activities

Deploy seismological equipment in the field, in collaboration with the University of Sheffield and the Asiaq Institute in Greenland

• Analyse and combine seismological data with different observations: field-measured discharge, modelled surface melt, and subglacial water pressure
• Interpret observations and model the physical processes associated with flow turbulence and sediment transport
• Extrapolate the results to marine-terminating glaciers, where direct observations are more difficult to obtain
• Put the results into perspective to improve our understanding of the Greenland Ice Sheet’s response to climate change

Expected skills

Skills in seismology and fluid mechanics

• Ability to work in the field, particularly during equipment installation campaigns
• Good command of English, both written and spoken
• Strong interest in teamwork and international collaborations
• Interest in glaciology and climate change-related issues
• Experience or ease working in mountainous environments would be an asset

Desired qualification: PhD in geophysics, mechanics, or mechanical physics
