Philip H. Nelson, Stephen L. Santus
2011, Open-File Report 2011-1175
Gas, oil, and water production data were compiled from selected wells in two tight gas reservoirs-the Codell-Niobrara interval, comprised of the Codell Sandstone Member of the Carlile Shale and the Niobrara Formation; and the Dakota J interval, comprised mostly of the Muddy (J) Sandstone of the Dakota Group; both intervals...
Population status and population genetics of northern leopard frogs in Arizona
Tad C. Theimer, Charles A. Drost, Ryan P. O’Donnell, Karen E. Mock
2011, Open-File Report 2011-1186
Increasing isolation of populations by habitat fragmentation threatens the persistence of many species, both from stochastic loss of small isolated populations, and from inbreeding effects in populations that have become genetically isolated. In the southwestern United States, amphibian habitat is naturally patchy in occurrence because of the prevailing aridity of...
Constraining the age and magnitude of uplift in the northern National Petroleum Reserve in Alaska (NPRA): Apatite fission-track analysis of samples from three wells
David W. Houseknecht, Kenneth J. Bird, Paul O'Sullivan
2011, Professional Paper 1784-A
A broad, post-mid-Cretaceous uplift is defined in the northern National Petroleum Reserve in Alaska (NPRA) by regional truncation of Cretaceous strata, thermal maturity patterns, and amounts of exhumation estimated from sonic logs. Apatite fission-track (AFT) analysis of samples from three wells (South Meade No. 1, Topagoruk No. 1, and Ikpikpuk...

Turbidity and suspended-sediment concentration data were collected by the U.S. Geological Survey (USGS) at four stream stations--French Creek near Phoenixville, West Branch Brandywine Creek near Honey Brook, West Branch Brandywine Creek at Modena, and East Branch Brandywine Creek below Downingtown--in Chester County, Pa. Sedimentation and siltation is the leading cause...
Identification of last interglacial deposits in eastern Beringia: a cautionary note from the Palisades, interior Alaska
Alberto V. Reyes, Grant D. Zazula, Svetlana Kuzmina, Thomas A. Ager, Duane G. Froese
2011, Journal of Quaternary Science (26) 345-352
Last interglacial sediments in unglaciated Alaska and Yukon (eastern Beringia) are commonly identified by palaeoecological indicators and stratigraphic position ~2-5m above the regionally prominent Old Crow tephra (124 + or - 10ka). We demonstrate that this approach can yield erroneous age assignments using data from a new exposure at the...

Assessment of the geomorphic effects of large floods using streamgage data: The 1951 floods in eastern Kansas, USA
Mark W. Bowen, Kyle E. Juracek
2011, Physical Geography (32) 52-77
Data from 23 U.S. Geological Survey (USGS) streamgages were analyzed to assess the geomorphic effects (short-term change and subsequent recovery) of the record 1951 floods on streams in eastern Kansas. Flood-related, channel-bed elevation change was indicated for 17 gage sites, with substantial deposition at five sites and substantial erosion at...
Implications of discontinuous elevation gradients on fragmentation and restoration in patterned wetlands
Christa L. Zweig, Brian E. Reichert, Wiley M. Kitchens
2011, Ecosphere (2) 1-14
Large wetlands around the world face the possibility of degradation, not only from complete conversion, but also from subtle changes in their structure and function. While fragmentation and isolation of wetlands within heterogeneous landscapes has received much attention, the disruption of spatial patterns/processes within large wetland systems and the resulting...
Significance of zircon U-Pb ages from the Pescadero felsite, west-central California coast ranges
Robert J. McLaughlin, Diane E. Moore, W.G. Ernst, UWE C. Martens, J. C. Clark
2011, Geological Society of America Bulletin (123) 1497-1512
Weathered felsite is associated with the late Campanian–Maastrichtian Pigeon Point Formation near Pescadero, California. Poorly exposed, its age and correlation are uncertain. Is it part of the Pigeon Point section west of the San Gregorio–Hosgri fault? Does it rest on Nacimiento block basement? Is it dextrally offset from the Oligocene...

Walter E. Dean, Lisa A. Doner
2011, Open-File Report 2011-1106
Little Shingobee Lake and Fen are part of an extensive network of lakes and wetlands in the Shingobee River headwaters area of northwestern Minnesota. Prior to about 9800 radiocarbon years, most of the lakes in the Shingobee watershed area were interconnected to form glacial Lake Willobee. From 9800 to 7700...
Estimated 2008 groundwater potentiometric surface and predevelopment to 2008 water-level change in the Santa Fe Group aquifer system in the Albuquerque area, central New Mexico
Sarah E. Falk, Laura M. Bexfield, Scott K. Anderholm
2011, Scientific Investigations Map 3162
The water-supply requirements of the Albuquerque metropolitan area of central New Mexico have historically been met almost exclusively by groundwater withdrawal from the Santa Fe Group aquifer system. Previous studies have indicated that the large quantity of groundwater withdrawal relative to recharge has resulted in water-level declines in the aquifer...
