Michael R. Miller, Jay D. Garr, Peter S. Coates
2010, Wetlands (30) 939-947
Harvested rice fields provide critical foraging habitat for wintering waterfowl in North America, but their value depends upon post-harvest treatments. We visited harvested ricefields in the Sacramento Valley, California, during the winters of 2007 and 2008 (recent period) and recorded their observed status as harvested (standing or mechanically modified stubble),...
Changes in the timing of snowmelt and streamflow in Colorado: A response to recent warming
David W. Clow
2010, Journal of Climate (23) 2293-2306
Trends in the timing of snowmelt and associated runoff in Colorado were evaluated for the 1978-2007 water years using the regional Kendall test (RKT) on daily snow-water equivalent (SWE) data from snowpack telemetry (SNOTEL) sites and daily streamflow data from headwater streams. The RKT is a robust, nonparametric test that...

Antje Schwalb, Walter E. Dean, C. Sherilyn Fritz, Christoph E. Geiss, Bernd Kromer
2010, Quaternary Science Reviews (29) 2325-2339
Proxy evidence at decadal resolution from Late Holocene sediments from Pickerel Lake, northeastern South Dakota, shows distinct centennial cycles (400-700 years) in magnetic susceptibility; contents of carbonate, organic carbon, and major elements; abundance in ostracodes; and delta18O and delta13C values in calcite. Proxies indicate cyclic changes in eolian input, productivity,...

2010, Geochemistry, Geophysics, Geosystems (11)
A rapid headspace method for the simultaneous laboratory determination of intentionally introduced hydrologic tracers, sulfur hexafluoride (SF6), trifluoromethyl sulfur pentafluoride (SF5CF3), Halon 1211 (CF2ClBr), and other halocarbons in water and gases is described. The high sensitivity of the procedure allows for introduction of minimal tracer mass (a few grams) into...

Edmund E. Grote, Jayne Belnap, David C. Housman, Jed P. Sparks
2010, Global Change Biology (16) 2763-2774
Biological soil crusts (biocrusts) are an integral part of the soil system in arid regions worldwide, stabilizing soil surfaces, aiding vascular plant establishment, and are significant sources of ecosystem nitrogen and carbon. Hydration and temperature primarily control ecosystem CO2 flux in these systems. Using constructed mesocosms for incubations under controlled laboratory...

Jeff P. Raffensperger, Brandon J. Fleming, William S.L. Banks, Marilee A. Horn, Mark R. Nardi, David C. Andreasen
2010, Scientific Investigations Report 2010-5186
Increased groundwater withdrawals from confined aquifers in the Maryland Coastal Plain to supply anticipated growth at Fort George G. Meade (Fort Meade) and surrounding areas resulting from the Department of Defense Base Realignment and Closure Program may have adverse effects in the outcrop or near-outcrop areas. Specifically, increased pumping from...
Effects of groundwater withdrawal on borehole flow and salinity measured in deep monitor wells in Hawai'i: implications for groundwater management
Kolja Rotzoll
2010, Scientific Investigations Report 2010-5058
Water-resource managers in Hawai`i rely heavily on salinity profiles from deep monitor wells to estimate the thickness of freshwater and the depth to the midpoint of the transition zone between freshwater and saltwater in freshwater-lens systems. The deep monitor wells are typically open boreholes below the water table and extend...

2010, Report, Oregon Climate Assessment Report (OCAR, 2010)
Earth’s changing climate is expected to have significant physical impacts along the coast and estuarine shorelands of Oregon, ranging from increased erosion and inundation of low lying areas, to wetland loss and increased estuarine salinity. The environmental changes associated with climate change include rising sea levels, increased occurrences of severe...
Environmental investigations using diatom microfossils
Kathryn E. L. Smith, James G. Flocks
2010, Fact Sheet 2010-3115
Diatoms are unicellular phytoplankton (microscopic plant-like organisms) with cell walls made of silica (called a frustule).

2010, Open-File Report 2010-1276
Watersheds play many important roles in the carbon cycle: (1) they are a site for both terrestrial and aquatic carbon dioxide (CO2) removal through photosynthesis; (2) they transport living and decomposing organic carbon in streams and groundwater; and (3) they store organic carbon for widely varying lengths of time as...
