    • Surface-wave eikonal tomography in a scattering environment 

      Verdel, Arie; Gouedard, Pierre; Yao, Huajian; van der Hilst, Robert D. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
      Surface waves are of increasing interest in seismic prospecting. Traveltime tomography based on dispersion measurements is often used to process surface-wave data, but it has limitations due to the a priori information ...

    • Using SVD for improved interferometric Green’s function recovery. 

      Melo, Gabriela; Malcolm, Alison E.; Mikessel, Dylan; van Wijk, Kasper (Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
      Seismic interferometry is a technique used to estimate the Green’s function (GF) between two receiver locations, as if there were a source at one of the locations. By crosscorrelating the recorded seismic signals at the ...

    • Detecting medium changes from coda by interferometry 

      Poliannikov, Oleg V.; Malcolm, Alison E. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
      In many applications, sequestering CO[subscript 2] underground for example, determining whether or not the medium has changed is of primary importance, with secondary goals of locating and quantifying that change. We ...
