New digital magnetic anomaly database for North America New digital magnetic anomaly database for North America
The Geological Survey of Canada (GSC), U.S. Geological Survey (USGS), and Consejo de Recursos Minerales of Mexico (CRM) are compiling an upgraded digital magnetic anomaly database and map for North America. This trinational project is expected to be completed by late 2002.

Subglacial sediments: A regional geological template for iceflow in West Antarctica Subglacial sediments: A regional geological template for iceflow in West Antarctica
We use aerogeophysical data to estimate the distribution of marine subglacial sediments and fault-bounded sedimentary basins beneath the West Antarctic Ice Sheet (WAIS). We find that significant ice flow occurs exclusively in regions covered by subglacial sediments. The onsets and lateral margins of ice streams coincide with the limit of marine sediments. Lateral margins are also...

Aerogeophysical measurements of collapse-prone hydrothermally altered zones at Mount Rainier volcano Aerogeophysical measurements of collapse-prone hydrothermally altered zones at Mount Rainier volcano
Hydrothermally altered rocks can weaken volcanoes, increasing the potential for catastrophic sector collapses that can lead to destructive debris flows1. Evaluating the hazards associated with such alteration is difficult because alteration has been mapped on few active volcanoes1-4 and the distribution and severity of subsurface alteration is largely unknown on any active volcano. At...

High resolution, low altitude aeromagnetic and electromagnetic survey of Mt Rainier High resolution, low altitude aeromagnetic and electromagnetic survey of Mt Rainier
In October 1996, the USGS conducted a high resolution airborne magnetic and electromagnetic survey in order to discern through-going sections of exposed altered rocks and those obscured beneath snow, vegetation and surficial unaltered rocks. Hydrothermally altered rocks weaken volcanic edifices, creating the potential for catastrophic sector collapses and ensuing formation of destructive...
