    • Executive Summary 

      Burns, Daniel R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2000)
      During the past year we have continued to make progress on the difficult problems associated with extracting geological information from geophysical data sets. Our research results focus on three major areas of ...
    • Variable Grid Finite-Difference Modeling Including Surface Topography 

      Hayashi, Koichi; Burns, Daniel R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
      We have developed a two-dimensional viscoelastic finite-difference modeling method for highly complex topography. Realistic modeling of seismic wave propagation in the near surface is complicated by many factors, such ...
    • An Analysis Of Deconvolution: Modeling Reflectivity By Fractionally Integrated Noise 

      Saggaf, Muhammed M.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
      Reflection coefficients are observed in nature to have stochastic behavior that departs significantly from the white noise model. Conventional deconvolution methods, however, assume reflectivity to be a white noise ...
