Laura M. Norman, Miguel L. Villarreal, Cynthia S.A. Wallace, Claudia Z. Gil Anaya, Israel Diaz Arcos, Floyd Gray
2010, Open-File Report 2010-1156
The cities of Nogales, Sonora, and Nogales, Arizona, are located in the Ambos Nogales Watershed, a topographically irregular bowl-shaped area with a northward gradient. Throughout history, residents in both cities have been affected by flooding. Currently, the primary method for regulating this runoff is to build a series of detention...
West Florida Shelf: A natural laboratory for the study of ocean acidificiation
Pamela Hallock, Lisa L. Robbins, Rebekka A. Larson, Tanya Beck, Patrick Schwing, Michael Martinez-Colon, Brad Gooch
2010, Open-File Report 2010-1134
Declining oceanic pH and carbonate-ion concentrations are well-known consequences of increased atmospheric and surface-ocean partial pressure of carbon dioxide (pCO2). The possible subject of shifts in seawater carbonate chemistry on biocalcification and survival rates of marine organisms provides questions amenable to both experimental and field study (Kleypas and Langdon, 2006)....
A geologic and anthropogenic journey from the Precambrian to the new energy economy through the San Juan volcanic field
Douglas B. Yager, Alison Burchell Alison, Raymond H. Johnson
2010, Book chapter, Through the generations: Geologic and anthropogenic field excursions in the Rocky Mountains from modern to ancient
The San Juan volcanic field comprises 25,000 km2 of intermediate composition mid-Tertiary volcanic rocks and dacitic to rhyolitic calderas including the San Juan–Uncompahgre and La Garita caldera-forming super-volcanoes. The region is famous for the geological, ecological, hydrological, archeological, and climatological diversity. These characteristics supported ancestral Puebloan populations....

Protocols for geologic hazards response by the Yellowstone Volcano Observatory to activity within the Yellowstone Volcanic System
Yellowstone Volcano Observatory
2010, Circular 1351
Executive SummaryThe Yellowstone Plateau hosts an active volcanic system, with subterranean magma (molten rock), boiling, pressurized waters, and a variety of active faults with significant earthquake hazards. Within the next few decades, light-to-moderate earthquakes and steam explosions are certain to occur. Volcanic eruptions are less likely, but are ultimately inevitable...
