2010, Fact Sheet 2010-3028
Alaska is noteworthy as a region of frequent seismic and volcanic activity. The region contains 52 historically active volcanoes, 14 of which have had at least one major eruptive event since 1990. Despite the high frequency of volcanic activity in Alaska, comprehensive studies of how ecosystems respond to volcanic eruptions...
Sediment-hosted lead-zinc deposits in Earth history
David L Leach, Dwight Bradley, David Huston, Sergei A. Pisarevsky, Ryan D. Taylor, S. Gardoll
2010, Economic Geology (105) 593-625
Sediment-hosted Pb-Zn deposits can be divided into two major subtypes. The first subtype is clastic-dominated lead-zinc (CD Pb-Zn) ores, which are hosted in shale, sandstone, siltstone, or mixed clastic rocks, or occur as carbonate replacement, within a CD sedimentary rock sequence. This subtype includes deposits that have been traditionally referred...
Secular variation in economic geology
Richard J. Goldfarb, Dwight Bradley, David L Leach
2010, Economic Geology (105) 459-465
The temporal pattern of ore deposits on a constantly evolving Earth reflects the complex interplay between the evolving global tectonic regime, episodic mantle plume events, overall changes in global heat flow, atmospheric and oceanic redox states, and even singular impact and glaciation events. Within...
Abdominally implanted transmitters with percutaneous antennas affect the dive performance of Common Eiders
Abby N. Powell, Christopher J. Latty, Tuula E. Hollmén, Margaret R. Petersen, Russel D. Andrews
2010, Condor (112) 314-322
Implanted transmitters have become an important tool for studying the ecology of sea ducks, but their effects remain largely undocumented. To address this, we assessed how abdominally implanted transmitters with percutaneous antennas affect the vertical dive speeds, stroke frequencies, bottom time, and dive duration of captive Common Eiders (Somateria mollissima)....

Multitemporal L- and C-Band synthetic aperture radar to highlight differences in water status among boreal forest and wetland systems in the Yukon Flats, Interior Alaska
Andrew W. Balser, Bruce K. Wylie
2010, Open-File Report 2010-1027
Tracking landscape-scale water status in high-latitude boreal systems is indispensable to understanding the fate of stored and sequestered carbon in a climate change scenario. Spaceborne synthetic aperture radar (SAR) imagery provides critical information for water and moisture status in Alaskan boreal environments at the landscape scale. When combined with results...
Abundance, Timing of Migration, and Egg-to-Smolt Survival of Juvenile Chum Salmon, Kwethluk River, Alaska, 2007 and 2008
Sean E. Burril, Christian E. Zimmerman, James E. Finn, Water Resources Division, U.S. Geological Survey, Daniel Gillikin, U.S. Fish and Wildlife Service
2010, Open-File Report 2010-1028
To better understand and partition mortality among life stages of chum salmon (Oncorhynchus keta), we used inclined-plane traps to monitor the migration of juveniles in the Kwethluk River, Alaska in 2007 and 2008. The migration of juvenile chum salmon peaked in mid-May and catch rates were greatest when water levels...
Rheologic and structural controls on the deformation of Okmok volcano, Alaska: FEMs, InSAR, and ambient noise tomography
Timothy Masterlark, Matthew M. Haney, Haylee Dickinson, Cheryl Searcy, T. Fournier
2010, Journal of Geophysical Research B: Solid Earth (115)
Interferometric synthetic aperture radar (InSAR) data indicate that the caldera of Okmok volcano, Alaska, subsided more than a meter during its eruption in 1997. The large deformation suggests a relatively shallow magma reservoir beneath Okmok. Seismic tomography using ambient ocean noise reveals two low‐velocity zones (LVZs). The shallow LVZ corresponds...

Glacier microseismicity
Michael E. West, Christopher F. Larsen, Martin Truffer, Shad O’Neel, Laura LeBlanc
2010, Geology (38) 319-322
We present a framework for interpreting small glacier seismic events based on data collected near the center of Bering Glacier, Alaska, in spring 2007. We find extremely high microseismicity rates (as many as tens of events per minute) occurring largely within a few kilometers of the receivers. A high-frequency class...
