Geology, Minerals, Energy, and Geophysics Science Center

Home

Scientists with the GMEG Science Center work on issues related to geologic processes, mineral and energy resource potential, and past climate, primarily in the Western United States. The science staff includes Geologists, Geophysicists, Geochemists, Biologists, and Geographic Information Systems specialists located in Arizona, California, Nevada, Oregon, and Washington.

Primary Research Direction - What we do.

GMEGSC focuses on Geologic Mapping, Mineral Resources and Mineral Environmental Health, Landslide Hazards, Energy Resources, Earthquake Hazards, and Land Change Science.

Innovation - How we help.

GMEGSC hosts the USGS Innovation Center, which sponsors work with public and private technology partners to design, test, and bring into operation a new generation of technical and engineering tools to address urgent national natural science issues.

Disciplinary Expertise - How we do it.

GMEGSC utilizes Geologic Mapping and Tectonics, Geophysics, Economic Geology, Geochronology, Sedimentary Basin Studies and Energy Assessments, Landslide Hazards, Geomorphology, Paleoclimatology, and many more processes to complete our work!

USGS permafrost research determines the risks of permafrost thaw to biologic and hydrologic resources

The U.S. Geological Survey (USGS), in collaboration with university, Federal, Tribal, and independent partners, conducts fundamental research on the distribution, vulnerability, and importance of permafrost in arctic and boreal ecosystems. Scientists, land managers, and policy makers use USGS data to help make decisions for development, wildlife...

Linking modern pollen accumulation rates to biomass: Quantitative vegetation reconstruction in the western Klamath Mountains, NW California, USA

Quantitative reconstructions of vegetation abundance from sediment-derived pollen systems provide unique insights into past ecological conditions. Recently, the use of pollen accumulation rates (PAR, grains cm−2 year−1) has shown promise as a bioproxy for plant abundance. However, successfully reconstructing region-specific vegetation dynamics...

Eroding Cascadia—Sediment and solute transport and landscape denudation in western Oregon and northwestern California

Riverine measurements of sediment and solute transport give empirical basin-scale estimates of bed-load, suspended-sediment, and silicate-solute fluxes for 100,000 km2 of northwestern California and western Oregon. This spatially explicit sediment budget shows the multifaceted control of geology and physiography on the rates and processes of...
