Caractérisation de l'état du pergélisol sous-marin par inversion de formes d’onde complète viscoélastique

An ACAN is a public notice indicating to the supplier community that a department or agency intends to award a contract for services to a pre-identified supplier, thereby allowing other suppliers to signal their interest in bidding, by submitting a statement of capabilities.
NRCan requires the contractor to perform the following tasks:
a) Construct four synthetic geological media with the following characteristics:

• partially frozen sands with interstitial water of intermediate salinity,
• partially frozen silts with interstitial water of intermediate salinity,
• frozen sands with interstitial water with low salinity,
• silts frozen with interstitial water with low salinity.

(b) Direct modeling of the propagation of a viscoelastic wave for the four media specified in (a)
c) Perform viscoelastic full waveform inversion of the results obtained in b).
d) Prepare a report outlining the limits of exploration seismology to detect and characterize the state of the subsea permafrost according to the different case studies specified in a).
