Characterization of the state of the submarine permafrost by viscoelastic complete waveform inversion

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).
