An overview of the Landsat Data Continuity Mission An overview of the Landsat Data Continuity Mission
The Landsat Data Continuity Mission (LDCM) is the follow-on mission to Landsat 7 and will be the eighth mission in the Landsat series. The mission is in development via an interagency partnership between the National Aeronautics and Space Administration (NASA) and the Department of Interior (DOI) / United States Geological Survey (USGS). The LDCM satellite will carry two earth-observing...

Supply of and demand for selected energy related mineral commodities Supply of and demand for selected energy related mineral commodities
In this report, subjects discussed include components of mineral supply, production, and consumption data, and information on selected mineral commodities in which the Energy Critical Elements Study Group has an interest, and U.S. Geological Survey (USGS) recycling studies, with some results of these studies.

Correlation of the Miocene Peach Spring Tuff with the geomagnetic polarity time scale and new constraints on tectonic rotations in the Mojave Desert, California Correlation of the Miocene Peach Spring Tuff with the geomagnetic polarity time scale and new constraints on tectonic rotations in the Mojave Desert, California
We report new paleomagnetic results and 40Ar/39Ar ages from the Peach Spring Tuff (PST), a key marker bed that occurs in the desert region between Barstow, California, and Peach Springs, Arizona. The 40Ar/39Ar ages were determined using individual hand-picked sanidine crystals from ash-flow specimens used in previous paleomagnetic studies at eight sites correlated by mineralogy...

Reconnaissance geochronology of tuffs in the Miocene Barstow Formation: Implications for basin evolution and tectonics in the central Mojave Desert Reconnaissance geochronology of tuffs in the Miocene Barstow Formation: Implications for basin evolution and tectonics in the central Mojave Desert
Early to middle Miocene lacustrine strata of the Barstow Formation are well dated in just a few places, limiting our ability to infer basin evolution and regional tectonics. At the type section in the Mud Hills, previous studies have shown that the lacustrine interval of the Barstow Formation is between ~16.3 Ma and ~13.4 Ma. Elsewhere, lake beds of the Barstow Formation have yielded...

Stratigraphy, age, and depositional setting of the Miocene Barstow Formation at Harvard Hill, central Mojave Desert, California Stratigraphy, age, and depositional setting of the Miocene Barstow Formation at Harvard Hill, central Mojave Desert, California
New detailed geologic mapping and geochronology of the Barstow Formation at Harvard Hill, 30 km east of Barstow, CA, help to constrain Miocene paleogeography and tectonics of the central Mojave Desert. A northern strand of the Quaternary ENE-striking, sinistral Manix fault divides the Barstow Formation at Harvard Hill into two distinct lithologic assemblages. Strata north of the fault...

Global change and water resources in the next 100 years Global change and water resources in the next 100 years
We are in the midst of a continental-scale, multi-year experiment in the United States, in which we have not defined our testable hypotheses or set the duration and scope of the experiment, which poses major water-resources challenges for the 21st century. What are we doing? We are expanding population at three times the national growth rate in our most water-scarce region, the...

Estimating salinity intrusion effects due to climate change on the Lower Savannah River Estuary Estimating salinity intrusion effects due to climate change on the Lower Savannah River Estuary
The ability of water-resource managers to adapt to future climatic change is especially challenging in coastal regions of the world. The East Coast of the United States falls into this category given the high number of people living along the Atlantic seaboard and the added strain on resources as populations continue to increase, particularly in the Southeast. Increased temperatures...

Variability of mercury concentrations in domestic well water, New Jersey Coastal Plain Variability of mercury concentrations in domestic well water, New Jersey Coastal Plain
Concentrations of total (unfiltered) mercury (Hg) exceed the Maximum Contaminant Level (2 µg/L) in the acidic water withdrawn by more than 700 domestic wells from the areally extensive unconfined Kirkwood-Cohansey aquifer system. Background concentrations of Hg generally are

Three-dimensional site response at KiK-net downhole arrays Three-dimensional site response at KiK-net downhole arrays
Ground motions at two Kiban-Kyoshin Network (KiK-net) strong motion downhole array sites in Hokkaido, Japan (TKCH08 in Taiki and TKCH05 in Honbetsu) illustrate the importance of three-dimensional (3D) site effects. These sites recorded the M8.0 2003 Tokachi-Oki earthquake, with recorded accelerations above 0.4 g at both sites as well as numerous ground motions from smaller events. Weak...

Extraction of organic compounds from organic-rich rocks during geologic CO2 sequestration at supercritical conditions Extraction of organic compounds from organic-rich rocks during geologic CO2 sequestration at supercritical conditions
At reservoir conditionscarbon dioxide is a supercritical fluid capable of extraction of naturallyoccurring neutral compounds from formation materials, including carboxylicacids at low pH. We performed a series of experiments designed to quantify theextractable carboxylic acid and neutral aromatic yield from coal of the WilcoxGroup in Louisiana. We determined concentrations of organic...
