Gravity Data Spreadsheets

These gravity data spreadsheets are Microsoft Excel documents containing functions that convert observed meter readings to gravity using the meter calibration table (for LaCoste & Romberg relative-gravity meters), applies a tide correction, calculates and plots drift using the Roman (1946) method, and calculates average gravity differences between each station pair.

GSadjust

GSadjust is the first comprehensive, publicly-available graphical interface for performing drift-correction and network adjustment for combined relative- and absolute-gravity surveys (Kennedy and others, 2021). The objective of network adjustment is to determine a single, best-fit gravity value at each station based on all available observations and their respective uncertainty. Typically the obse

GSadjust: a graphical user interface for processing combined relative- and absolute-gravity surveys

GSadjust is a graphical user interface for processing relative-gravity surveys. It provides an interface for data selection, drift evaluation and correction, network adjustment, for data from modern relative (Scintrex, ZLS) and absolute (Micro-g LaCoste) gravity meters. 

Computer Programs for Telescopic Mesh Refinement using MODFLOW-96: MODTMR, TMRDIFF, and RIVGRID

MODTMR - A program for telescopic mesh refinement using MODFLOW TMRDIFF - A program to provide a means of comparing computed head or drawdown in local and regional models in applications of telescopic mesh refinement. RIVGRID - A program to construct MODFLOW data sets for head-dependent boundaries using grid-independent data sets
