Imaging geophysicists often have to be content with tomographic velocity models obtained using fixed anisotropy parameters. Interpretation geophysicists often have to accept image volumes without a good measure of uncertainty. To those who have qualms about hand-specifying anisotropy parameters, and to those who question hand-ascribing uncertainties to Earth models, I suggest the current May-June issue of Geophysics. It contains an exciting special section on Borehole Geophysics. I applaud the great efforts of the editors, reviewers, and authors who have contributed to the section. We need such contributions to anchor our wealth of full-azimuth surface data by sound statistical analysis of well data and improved understanding of rock physics. The following are two brief samples of the May-June issue. I invite you to browse through the entire issue for the latest developments in exploration geophysics.
