A-024 SIMULTANEOUS LEAST SQUARES DECONVOLUTION AND KRIGING USING CONJUGATE GRADIENTS JONATHAN KANE WILLIAM RODI and M. NAFI TOKSÖZ Earth Resources Laboratory Massachusetts Institute of Technology 42 Carleton St. Cambridge Ma. 02142 Summary Least squares deconvolution is a method used to sharpen tomographic images of the earth by undoing the bandlimiting effects imposed by a seismic wavelet. Kriging is a method used by geoscientists to extrapolate and interpolate sparse data sets. These two methodologies have traditionally been kept separate and viewed as unrelated fields of research. We demonstrate the connection between these methods by deriving them both as examples of linear
