Beavers and their dams are common sights along creeks in the Tualatin River basin. Beaver help create diverse habitats for many other animals, including birds, fish, and amphibians. The USGS studying the affect beaver activity has on the amount and quality of water in local streams, so that agencies in the basin can make strategic management and habitat restoration decisions based on science...
A key component to assessing the contaminant exposure pathways in streams and rivers of the Chesapeake Bay is using GIS-based landscape analysis to identify sources of endocrine disrupting chemicals. Municipal and industrial wastewater treatment plant (WWTP) discharges are potentially major sources of EDCs to streams, and therefore understanding the de facto wastewater reuse (represented as...
Although sparsely populated, this area in southeastern Oregon, northeastern California, northwestern Nevada, and southeastern Idaho has high geothermal heat flow that may be used to generate large amounts of electricity.
Fish, wildlife, and human populations along the lower Columbia River are exposed to an ever-growing variety of contaminants as a result of increasing urbanization, industrialization, and agricultural development.
The Camas National Wildlife Refugeprovides essential resting, feeding, and nesting habitat for waterfowl including migratory birds. A variety of other animals, large and small, are found there, too. Since the refuge was established in 1937, the U.S. Fish and Wildlife Service (USFWS) has been responsible for managing this vital resource.
Traditionally, Camas Creek and groundwater inflow...

Oběh vody: The Water Cycle
Co to je oběh vody?
Co to je oběh vody? Mohl bych si jednoduše odpovědět – je všude kolem mne ! Oběh vody znamená přítomnost a pohyb vody na Zemi, v Zemi i nad Zemí. Voda je stále v pohybu a neustále mění svoji formu, z kapalné do plynné či pevné, a naopak. Oběh vody existuje již po miliardy let a veškerý pozemský život je na něm závislý; Země by bez...
Degradation of crude 4-MCHM (4-methylcyclohexanemethanol) in sediments from Elk River, West Virginia
In January 2014, approximately 37 800 L of crude 4-methylcyclohexanemethanol (crude MCHM) spilled into the Elk River, West Virginia. To understand the long-term fate of 4-MCHM, we conducted experiments under environmentally relevant conditions to assess the potential for the 2 primary compounds in crude MCHM (1) to undergo biodegradation and (2)...Cozzarelli, Isabelle M.; Akob, Denise M.; Baedecker, Mary; Spencer, Tracey; Jaeschke, Jeanne B.; Dunlap, Darren S.; Mumford, Adam C.; Poret-Peterson, Amisha T.; Chambers, Douglas B.
Annual estimates of recharge, quick-flow runoff, and ET for the contiguous U.S. using empirical regression equations
This study presents new data-driven, annual estimates of the division of precipitation into the recharge, quick-flow runoff, and evapotranspiration (ET) water budget components for 2000-2013 for the contiguous United States (CONUS). The algorithms used to produce these maps ensure water budget consistency over this broad spatial scale, with...Reitz, Meredith; Sanford, Ward E.; Senay, Gabriel; Cazenas, J.
The land-sea interface: A source of high-quality phytoplankton to support secondary production
Coastal-estuarine systems are among the most productive marine ecosystems and their special role in producing harvestable fish and shellfish has been attributed to high primary production fueled by nutrient runoff from land and efficient trophic transfer. Here we ask if phytoplankton species composition and their food quality based on the...Winder, Monika; Carstensen, Jacob; Galloway, Aaron W.E.; Jakobsen, Hans H.; Cloern, James E.
Novel analyses of long-term data provide a scientific basis for chlorophyll-a thresholds in San Francisco Bay
San Francisco Bay (SFB), USA, is highly enriched in nitrogen and phosphorus, but has been resistant to the classic symptoms of eutrophication associated with over-production of phytoplankton. Observations in recent years suggest that this resistance may be weakening, shown by: significant increases of chlorophyll-a (chl-a) and decreases...Sutula, Martha; Kudela, Raphael; Hagy, James D.; Harding, Lawrence W.; Senn, David; Cloern, James E.; Bricker, Suzanne B.; Beck, Marcus W.; Berg, Gry Mine
A hydrologic drying bias in water-resource impact analyses of anthropogenic climate change
For water-resource planning, sensitivity of freshwater availability to anthropogenic climate change (ACC) often is analyzed with “offline” hydrologic models that use precipitation and potential evapotranspiration (Ep) as inputs. Because Ep is not a climate-model output, an intermediary model of Ep must be introduced to connect the climate model to...Milly, Paul; Dunne, Krista A.
The role of alluvial aquifer sediments in attenuating a dissolved arsenic plume
In a crude-oil-contaminated sandy aquifer at the Bemidji site in northern Minnesota, biodegradation of petroleum hydrocarbons has resulted in release of naturally occurring As to groundwater under Fe-reducing conditions. This study used chemical extractions of aquifer sediments collected in 1993 and 2011–2014 to evaluate the relationship between...Ziegler, Brady A.; Schreiber, Madeline E.; Cozzarelli, Isabelle M.
A field study of selected U.S. Geological Survey analytical methods for measuring pesticides in filtered stream water, June - September 2012

Coastal eolian sand-ramp development related to paleo-sea-level changes during the Latest Pleistocene and Holocene (21–0 ka) in San Miguel Island, California, U.S.A.
Coastal eolian sand ramps (5–130 m elevation) on the northern slope (windward) side of the small San Miguel Island (13 km in W-E length) range in age from late Pleistocene to modern time, though a major hiatus in sand-ramp growth occurred during the early Holocene marine transgression (16–9 ka). The Holocene sand ramps (1–5 m measured thicknesses...Peterson, Curt D.; Erlandson, Jon M.; Stock, Errol; Hostetler, Steven W.; Price, David M.
Evidence of coupled carbon and iron cycling at a hydrocarbon-contaminated site from time lapse magnetic susceptibility
Conventional characterization and monitoring of hydrocarbon (HC) pollution is often expensive and time-consuming. Magnetic susceptibility (MS) has been proposed as an inexpensive, long-term monitoring proxy of the degradation of HC. We acquired repeated down hole MS logging data in boreholes at a HC-contaminated field research site in Bemidji, MN...Lund, Anders L.; Slater, Lee D.; Atekwana, Estella A.; Ntarlagiannis, Dimitrios; Cozzarelli, Isabelle M.; Bekins, Barbara A.
Interactive effects of deer exclusion and exotic plant removal on deciduous forest understory communities
