Climate and streamflow trends in the Columbia River basin: evidence for ecological and engineering resilience to climate change

Creator:: Hatcher, Kendra L. and Jones, Julia A.
Abstract:: Large river basins integrate the signal of water from atmospheres to oceans. Climate change is widely expected to alter streamflow and potentially disrupt water management systems. We tested the ecological resilience -- capacity of headwater ecosystems to sustain streamflow under climate change – and the engineering resilience – capacity of...

Interactive visual analysis promotes exploration of long-term ecological data

Creator:: Pham, Tuan, Jones, Julia A., Metoyer, Ronald, Swanson, Frederick, and Pabst, Robert
Abstract:: Long-term ecological data are crucial in helping ecologists understand ecosystem function and environmental change. Nevertheless, these kinds of data sets are difficult to analyze because they are usually large, multivariate, and spatiotemporal. Although existing analysis tools such as statistical methods and spreadsheet software permit rigorous tests of pre-conceived hypotheses and...

Metabolic engineering of cyanobacteria to optimize photobiological hydrogen production

Creator:: Luterra, Markael
Abstract:: Photobiological hydrogen production -- the use of photosynthesis to split water into hydrogen and oxygen -- presents an opportunity for efficient and large-scale solar biofuel development. One of the major challenges in this area is competition for reductant between the hydrogen-evolving hydrogenase enzyme and other metabolic pathways. In this work...

River restoration practitioner survey on engineering design for climate change

Creator:: Tullos, Desiree
Abstract:: An online survey of river restoration practitioners, engineers, and researchers was conducted to examine current practices and perspectives on how climate change is integrated into engineering designs for river restoration. Seventy-six responses were submitted to the survey. While the responses came from a wide range of demographies, respondents were most...

Metabolic engineering of Shewanella oneidensis MR-1 for microbial fuel cell application

Creator:: Hall, Robert G. (Robert George)
Abstract:: Shewanella oneidensis MR-1 is a gram-negative, facultative anaerobic bacteria with the capability of dissimilatory metal reduction. The ability of the organism to reduce a wide range of solid metal-oxides during anaerobic respiration makes it an ideal candidate for the powering of microbial fuel cells (MFCs), which capture the electrons discharged...

Biophysical feedback mediates effects of invasive grasses on coastal dune shape

Creator:: Zarnetske, Phoebe L., Hacker, Sally D., Seabloom, Eric W., Ruggiero, Peter, Killian, Jason R., Maddux, Timothy B., and Cox, Daniel
Abstract:: Vegetation at the aquatic–terrestrial interface can alter landscape features through its growth and interactions with sediment and fluids. Even similar species may impart different effects due to variation in their interactions and feedbacks with the environment. Consequently, replacement of one engineering species by another can cause significant change in the...

A Tale of Two Spills: Novel Science and Policy Implications of an Emerging New Oil Spill Model

Creator:: Peterson, Charles H., Anderson, Sean S., Cherr, Gary N., Ambrose, Richard F., Anghera, Shelly, Bay, Steven, Blum, Michael, Condon, Robert, Dean, Thomas A., Graham, Monty, Guzy, Michael, Hampton, Stephanie, Joye, Samantha, Lambrinos, John, Mate, Bruce, Meffert, Douglas, Powers, Sean P., Somasundaran, Ponisseril, Spies, Robert B., Taylor, Caz M., Tjeerdema, Ronald, and Adams, E. Eric
Abstract:: The 2010 Deepwater Horizon oil release posed the challenges of two types of spill: a familiar spill characterized by buoyant oil, fouling and killing organisms at the sea surface and eventually grounding on and damaging sensitive shoreline habitats, and a novel deepwater spill involving many unknowns. The subsurface retention of...

Calibrating Single-Ended Fiber-Optic Raman Spectra Distributed Temperature Sensing Data

Creator:: Hausner, Mark B., Suarez, Francisco, Glander, Kenneth E., van de Giesen, Nick, Selker, John S., and Tyler, Scott W.
Abstract:: Hydrologic research is a very demanding application of fiber-optic distributed temperature sensing (DTS) in terms of precision, accuracy and calibration. The physics behind the most frequently used DTS instruments are considered as they apply to four calibration methods for single-ended DTS installations. The new methods presented are more accurate than...

Potential for ethanol production from conservation reserve program lands in Oregon

Creator:: Juneja, Ankita, Kumar, Deepak, Williams, John D., Wysocki, Donald J., and Murthy, Ganti S.
Abstract:: Increase in energy demand has led towards considering lignocellulosic feedstocks as potential for ethanol production. Aim of this study was to estimate the potential of grass straws from conservation reserve program (CRP) lands as feedstocks for ethanol production. The CRP was initiated to ensure reduction in soil erosion with a...

Double-Ended Calibration of Fiber-Optic Raman Spectra Distributed Temperature Sensing Data

Creator:: van de Giesen, Nick, Steele-Dunne, Susan C., Jansen, Jop, Hoes, Olivier, Hausner, Mark B., Tyler, Scott, and Selker, John
Abstract:: Over the past five years, Distributed Temperature Sensing (DTS) along fiber optic cables using Raman backscattering has become an important tool in the environmental sciences. Many environmental applications of DTS demand very accurate temperature measurements, with typical RMSE < 0.1 K. The aim of this paper is to describe and...
