On the Hydrologic Adjustment of Climate-Model Projections: The Potential Pitfall of Potential Evapotranspiration
Paul C.D. Milly, Krista A. Dunne
2011, Earth Interactions (15) 1-14
Hydrologic models often are applied to adjust projections of hydroclimatic change that come from climate models. Such adjustment includes climate-bias correction, spatial refinement ("downscaling"), and consideration of the roles of hydrologic processes that were neglected in the climate model. Described herein is a quantitative analysis of the effects of hydrologic...
Measurement of net nitrogen and phosphorus mineralization in wetland soils using a modification of the resin-core technique
Gregory B. Noe
2011, Biogeochemistry (75) 760-770
A modification of the resin-core method was developed and tested for measuring in situ soil N and P net mineralization rates in wetland soils where temporal variation in bidirectional vertical water movement and saturation can complicate measurement. The modified design includes three mixed-bed ion-exchange resin bags located above and three...

In accord with the hypotheses driving the Southern Ocean Global Ocean Ecosystems Dynamics (SO GLOBEC) program, we tested the hypothesis that the winter foraging ecology of a major top predator in waters off the Western Antarctic Peninsula (WAP), the Adélie penguin (Pygoscelis adeliae), is constrained by oceanographic features related to...
Swimming and other activities: applied aspects of fish swimming performance
Theodore R. Castro-Santos
A.P. Farrell, editor(s)
2011, Book chapter, Encyclopedia of fish physiology: from genome to the environment
Human activities such as hydropower development, water withdrawals, and commercial fisheries often put fish species at risk. Engineered solutions designed to protect species or their life stages are frequently based on assumptions about swimming performance and behaviors. In many cases, however, the appropriate data to support these designs are either...
A buoyant plume adjacent to a headland-Observations of the Elwha River plume
Jonathan A. Warrick, Andrew W. Stevens
2011, Continental Shelf Research (31) 85-97
Small rivers commonly discharge into coastal settings with topographic complexities – such as headlands and islands – but these settings are underrepresented in river plume studies compared to more simplified, straight coasts. The Elwha River provides a unique opportunity to study the effects of coastal topography on a buoyant plume,...

2011, Conference Paper, Proceedings of the workshop on engineered barrier performance related to low-level radioactive waste, decommissioning, and uranium mill tailings facilities (NUREG/CP-0195)
In 1976 the U.S. Geological Survey (USGS) began studies of unsaturated zone hydrology next to the Nation’s first commercial disposal facility for low-level radioactive waste (LLRW) near Beatty, NV. Recognizing the need for long-term data collection, the USGS in 1983 established research management areas in the vicinity of the waste-burial...

Potential increase in floods in California's Sierra Nevada under future climate projections
T. Das, M. D. Dettinger, D.R. Cayan, H.G. Hidalgo
2011, Climatic Change (109) 71-94
California’s mountainous topography, exposure to occasional heavily moisture-laden storm systems, and varied communities and infrastructures in low lying areas make it highly vulnerable to floods. An important question facing the state—in terms of protecting the public and formulating water management responses to climate change—is “how might future climate changes affect...
Coherence of river and ocean conditions along the US West Coast during storms

2011, Continental Shelf Research (31) 789-805
The majority of water and sediment discharge from the small, mountainous watersheds of the US West Coast occurs during and immediately following winter storms. The physical conditions (waves, currents, and winds) within and acting upon the proximal coastal ocean during these winter storms strongly influence dispersal patterns. We examined this...
