A framework for 3-D joint inversion of MT, gravity and seismic refraction data (2011, background): “We show some of the options for various modules in red boxes. large-scale inversion: the total computational cost and the memory requirements (Newman & Alumbaugh 2000).”
Three-dimensional magnetotelluric inversion : data-space method (2005, methodology): “One way around this difficulty (e.g.,Sasaki, 2001; Newman and Alumbaugh, 2000) is to use a very coarse parameterization of the conductivity variations, so thatM remains small.”
ModEM: A modular system for inversion of electromagnetic geophysical data (2014, positive): “Geophysical electromagnetic inversion approaches and parallel computer codes have developed rapidly in the past decade or so (notably, Newman and Alumbaugh, 2000; Zhdanov and Hursan, 2000; Haber et al., 2004; Newman and Boggs, 2004; Kelbert et al., 2008; Siripunvaraporn and Egbert, 2009; Avdeev and…”
