Ronald B. Zelt, Christopher M. Hobza, Bethany L. Burton, Nathaniel J. Schaepe, Nadine M. Piatak
2017, Scientific Investigations Report 2017-5105
Sediment management is a challenge faced by reservoir managers who have several potential options, including dredging, for mitigation of storage capacity lost to sedimentation. As sediment is removed from reservoir storage, potential use of the sediment for socioeconomic or ecological benefit could potentially defray some costs of its removal. Rivers...

Christopher Good, John Davidson, Luke R. Iwanowicz, Michael T. Meyer, Julie E. Dietze, Dana W. Kolpin, David Marancik, Jill Birkett, Christina Williams, Steven T. Summerfelt
2017, Aquacultural Engineering (78) 2-8
A major issue affecting land-based, closed containment Atlantic salmon Salmo salar growout production in water recirculation aquaculture systems (RAS) is precocious male maturation, which can negatively impact factors such as feed conversion, fillet yield, and product quality. Along with other water quality parameters, elevated nitrate nitrogen (NO3-N) has been shown to influence the reproductive...

Cletus Blum, Tim White, Edward A. Sauter, Duff Stewart, Paul A. Bedrosian, Jeffrey J. Love
2017, Geoscientific Instrumentation, Methods and Data Systems (6) 447-452
Despite its importance to a range of applied and fundamental studies, and obvious parallels to a robust network of magnetic-field observatories, long-term geoelectric field monitoring is rarely performed. The installation of a new geoelectric monitoring system at the Boulder magnetic observatory of the US Geological Survey is summarized. Data from...

Thomas M. Cronin, Gary S. Dwyer, Emma Caverly, Jesse Farmer, Lauren H. DeNinno, Julio Rodriguez-Lazaro, Laura Gemery
2017, Scientific Reports (7)
Arctic Ocean temperatures influence ecosystems, sea ice, species diversity, biogeochemical cycling, seafloor methane stability, deep-sea circulation, and CO2 cycling. Today's Arctic Ocean and surrounding regions are undergoing climatic changes often attributed to "Arctic amplification" - that is, amplified warming in Arctic regions due to sea-ice loss and other processes, relative to...

Jennifer L. Lewicki, Peter J. Kelly, Deborah Bergfeld, R. Greg Vaughan, Jacob B. Lowenstern
2017, Journal of Volcanology and Geothermal Research (347) 312-326
We quantified gas and heat emissions in an acid-sulfate, vapor-dominated area (0.04-km2) of Norris Geyser Basin, located just north of the 0.63 Ma Yellowstone Caldera and near an area of anomalous uplift. From 14 May to 3 October 2016, an eddy covariance system measured half-hourly CO2, H2O and sensible (H) and...

Ashley Inserillo, Mark B. Green, James B. Shanley, Joseph Boyer
2017, Hydrological Processes (31) 1074-1085
A better understanding of stormwater generation and solute sources is needed to improve the protection of aquatic ecosystems, infrastructure, and human health from large runoff events. Much of our understanding of water and solutes produced during stormflow comes from studies of individual, small headwater catchments. This study compared many different...

Bathymetric map and area/capacity table for Castle Lake, Washington
Adam R. Mosbrucker, Kurt R. Spicer
2017, Open-File Report 2017-1145
The May 18, 1980, eruption of Mount St. Helens produced a 2.5-cubic-kilometer debris avalanche that dammed South Fork Castle Creek, causing Castle Lake to form behind a 20-meter-tall blockage. Risk of a catastrophic breach of the newly impounded lake led to outlet channel stabilization work, aggressive monitoring programs, mapping...

Morten T. Limborg, Wesley Larson, Kyle Shedd, Lisa W. Seeb, James E. Seeb
2017, Conservation Genetics Resources (10) 169-171
Preservation of heritable ecological diversity within species and populations is a key challenge for managing natural resources and wild populations. Salmonid fish are iconic and socio-economically important species for commercial, aquaculture, and recreational fisheries across the globe. Many salmonids are known to exhibit ecological divergence within species, including distinct feeding...

Deniz Karagulle, Charlie Frye, Roger Sayre, Sean P. Breyer, Peter Aniello, Randy Vaughan, Dawn J. Wright
2017, Transactions in GIS (21) 1040-1060
In 1964, E.H. Hammond proposed criteria for classifying and mapping physiographic regions of the United States. Hammond produced a map entitled “Classes of Land Surface Form in the Forty-Eight States, USA”, which is regarded as a pioneering and rigorous treatment of regional physiography. Several researchers automated Hammond?s model in GIS....
