Earth's ice hangs in the balance

Charles, Dan
June 1991
New Scientist;6/8/91, Vol. 130 Issue 1772, p22
Considers the dispute about the current variations in the Earth's ice cover and discusses a method proposed by geophysicist Bradford Hager from the Massachusetts Institute of Technology to help determine if Antarctica is sagging or rising. Proposed use of Very Long Baseline Interferometry (VLBI) or the Global Positioning System (GPS); Need for five or ten years of observations.

    Ocean tides close to the grounding line of outlet glaciers around Antarctica have been shown to directly influence ice velocity, in both linear and non-linear patterns. These fluctuations can be significant and have the potential to affect satellite measurements 5 of ice discharge which assume...

    This study explores an approach that simultaneously estimates Antarctic mass balance and glacial isostatic adjustment (GIA) through the combination of satellite gravity and altimetry data sets. The results improve upon previous efforts by incorporating reprocessed data sets over a longer period...

    We present an empirical model for periodic variations of diurnal and sub-diurnal Earth rotation parameters (ERPs) that was derived based on the transformation of normal equation (NEQ) systems of Very Long Baseline Interferometry (VLBI) observing sessions. NEQ systems that contain highly resolved...

    A nonintrusive remote sensing method to measure water level is examined. It relies on the fact that water is a good reflector of radio frequency energy, thus, on a satellite-to-ground path when the satellite is near the horizon, a readily detectable interference pattern is formed as the...

    One-baseline 1-h Very Long Baseline Interferometry (VLBI) Intensive sessions are carried out every day to determine Universal Time (UT1). Azimuthal asymmetry of tropospheric delays around the stations is usually ignored and not estimated because of the small number of observations. In this study...

    The article highlights the survey on the structural vibrations of structures in the U.S. The survey shows that multipath makes it difficult to detect very low-frequency structural vibrations, which is important in characterizing dynamic loads and determining safe structural lifetimes. Moreover,...

    The alignment of the Laser Interferometer Gravitational-Wave Observatory (LIGO) using the global positioning system (GPS) is described. The LIGO project is designed to detect gravitational waves from astrophysical sources by laser interferometry. There are two sites separated by 3002 km that...
