Abstracts of the Annual Meeting of Planetary Geologic Mappers, Nampa, Idaho 2006 Abstracts of the Annual Meeting of Planetary Geologic Mappers, Nampa, Idaho 2006
Approximately 18 people attended this year's mappers meeting, and many more submitted abstracts and maps in absentia. The meeting was held on the campus of Northwest Nazarene University (NNU), and was graciously hosted by NNU's School of Health and Science. Planetary mapper Dr. Jim Zimbelman is an alumnus of NNU, and he was pivotal in organizing the meeting at this location. Oral and...

Physical properties of two core samples from Well 34-9RD2 at the Coso geothermal field, California Physical properties of two core samples from Well 34-9RD2 at the Coso geothermal field, California
The Coso geothermal field, located along the Eastern California Shear Zone, is composed of fractured granitic rocks above a shallow heat source. Temperatures exceed 640 ?F (~338 ?C) at a depth of less than 10000 feet (3 km). Permeability varies throughout the geothermal field due to the competing processes of alteration and mineral precipitation, acting to reduce the interconnectivity of...

The reawakening of Alaska's Augustine volcano The reawakening of Alaska's Augustine volcano
Augustine volcano, in south central Alaska, ended a 20-year period of repose on 11 January 2006 with 13 explosive eruptions in 20 days. Explosive activity shifted to a quieter effusion of lava in early February, forming a new summit lava dome and two short, blocky lava flows by late March (Figure 1). The eruption was heralded by eight months of increasing seismicity, deformation, gas...

Toward "Supervolcano" technology Toward "Supervolcano" technology
In addition to depicting the ultimate volcano-eruption horror story, the recent Discovery Channel/BBC coproduction “Supervolcano” speculates about what technology will be available to the geophysicist in 2025 to monitor active volcanoes. The result is a fictional Virtual Geophysical Laboratory that, when fed the right data, predicts eruption scenarios, thereby providing information to...

USGS-NoGaDat - A global dataset of noble gas concentrations and their isotopic ratios in volcanic systems USGS-NoGaDat - A global dataset of noble gas concentrations and their isotopic ratios in volcanic systems
The database (Version 1.0) is a MS-Excel file that contains close to 5,000 entries of published information on noble gas concentrations and isotopic ratios from volcanic systems in Mid-Ocean ridges, ocean islands, seamounts, and oceanic and continental arcs (location map). Where they were available we also included the isotopic ratios of strontium, neodymium, and carbon. The database is...
