1.1. Pedagogic context#

1.1.1. IGE presentation#

    The Institute for Geosciences and Environmental research is a public research laboratory supported by CNRS/INSU, IRD, UGA and Grenoble-INP. Born from the fusion of the LGGE (Laboratory of Glaciology and Geophysics of Environment) and the LTHE (Laboratory of Transfers in Hydrology and Environment) in 2017, the research unit take part of the OSUG (Observatory for Sciences of Universe of Grenoble) and is involved in several national and international observation missions. The main fields of the IGE are Glaciology, Hydrology, Oceanography, atmospheric and environmental sciences. Combining these fields with inter and cross-disciplinary sciences due to human and social sciences or socio-economic actors, the laboratory studies climate and anthropization of Earth.

The institute is composed of 8 research teams :

  • CHIANTI : Atmospheric Chemistry

  • CRYODYN : Glaciers and ice sheets dynamics

  • C2H : Climat-Cryosphere-Hydrosphere

  • HMCIS : HydroMeteorology, Climat and Interactions in Socities

  • HyDRIMZ : Water, Soils, Sediment, Quality

  • ICE3 : Ice Cores, Climate, Chemistry

  • MEOM : Multiscale oceanic flow modeling

  • PHyREV : Hydrologcal Processes for Vulnerables Water Resources

There are also 3 support services providing the good working of the laboratory :

  • Administrative service

  • IT service (network, scientific computing, databases …)

  • Technical service : (drilling, observations, electronics and instrumentation, laboratory analysis, infrastructure)

The global staff of IGE counts around 240 people:

  • 145 permanent members (researchers, lecturers and professors, engineers, technicians and administrative staff)

  • 95 PhD students, post-doctoral fellows and staff on fixed-term contracts.

The laboratory is located on the University Campus in Grenoble, divided into 3 sites (Glaciology, OSUG-B and MCP)

1.1.2. CRYODYN research team#

    This internship is supervised by Thomas Chauve from CRYODYN. This research team has for goal to better understand and describe ice dynamics, leading to make better predictions about glaciers and ice caps transformations. These works are split in 2 research axis :

The dynamic recrystallization of ice is an intra-glacial mechanical process and take place into Axe 1.
