A large amount on past and ongoing scientific programs work(ed) on our cryosphere and generate a lot of debate about its dynamic, sustainability and behavior against climate changes.
A glacial system is able to produce a very large amount of sediment due to the tremendous erosive forces of ice at its base.
Furthermore, in the ancient, field and geophysical studies are carried out at lower resolution but on a wider scale (time and space).
Finally, even if Subglacial lakes are observed below ice sheets, melt-water drainage system processes ongoing, especially like the tunnel valleys remain unobserved directly.
[1] The record of these huge subglacial "rivers" is mainly analysed via the recent ice ages imprints (Weichselian, Saalian and Pre-Illinoian or Elsterian stages)[2][3] and in the ancient one (Late Ordovician[4] and Permo-Carboniferous[5]).
So, by joining the skills of three different universities, with the help of many data providers and the funding of six oil companies, new income is made into the knowledge of paleo-glacial systems.
