Space-based observations offer unique capabilities for studying spatial and temporal dynamics of the upper ocean inorganic carbon cycle and, in turn, supporting research tied to ocean acidification (OA). Satellite sensors measuring sea surface temperature, color, salinity, wind, waves, currents, and sea level enable a fuller understanding of a range of...

2016, Geological Society, London, Memoirs (46) 111-112
Pockmarks are seafloor depressions associated with fluid escape (Judd & Hovland 2007). They proliferate in the muddy seafloors of coastal Gulf of Maine and Bay of Fundy, where they are associated with shallow natural gas likely of biogenic origin (Ussler et al. 2003; Rogers et al. 2006;...
Influences of summer water temperatures on the movement, distribution, and resources use of fluvial Westslope Cutthroat Trout in the South Fork Clearwater River basin
Marika E. Dobos, Matthew P. Corsi, Daniel J. Schill, Joseph M. DuPont, Michael C. Quist
2016, North American Journal of Fisheries Management (36) 549-567
Although many Westslope Cutthroat Trout Oncorhynchus clarkii lewisi populations in Idaho are robust and stable, population densities in some systems remain below management objectives. In many of those systems, such as in the South Fork Clearwater River (SFCR) system, environmental conditions (e.g., summer temperatures) are hypothesized to limit populations of Westslope Cutthroat...

Andrew M. Ramey, Andrew B. Reeves, Joshua L. Teslaa, Sean W. Nashold, Tyrone F. Donnelly, Justin Bahl, Jeffrey S. Hall
2016, Infection, Genetics and Evolution (40) 176-185
Highly pathogenic clade 2.3.4.4 H5N8, H5N2, and H5N1 influenza A viruses were first detected in wild, captive, and domestic birds in North America in November–December 2014. In this study, we used wild waterbird samples collected in Alaska prior to the initial detection of clade 2.3.4.4 H5 influenza A viruses in...

John F. Stamm, Dennis Todey, Barbara Mayes Bousted, Shawn Rossi, Parker A. Norton, Janet M. Carter
2016, Scientific Investigations Report 2015-5135
Mountain snowpack is an important contributor to runoff in the Upper Missouri River Basin; for example, high amounts of winter and spring precipitation in the mountains and plains in 2010–11 were associated with the peak runoff of record in 2011 in the Upper Missouri River Basin. To project trends in...
Fecal indicator organism modeling and microbial source tracking in environmental waters: Chapter 3.4.6
Meredith Nevers, Muruleedhara Byappanahalli, Mantha S. Phanikumar, Richard L. Whitman
2016, Book chapter, Manual of Environmental Microbiology
Mathematical models have been widely applied to surface waters to estimate rates of settling, resuspension, flow, dispersion, and advection in order to calculate movement of particles that influence water quality. Of particular interest are the movement, survival, and persistence of microbial pathogens or their surrogates, which may contaminate recreational water,...

C. D. Smith, Michael C. Quist, R. S. Hardy
2016, River Research and Applications (32) 622-638
Longitudinal gradients of fish assemblage and habitat structure were investigated in the Kootenai River of northern Idaho. A total of 43 500-m river reaches was sampled repeatedly with several techniques (boat-mounted electrofishing, hoop nets and benthic trawls) in the summers of 2012 and 2013. Differences in habitat and fish assemblage structure...

Roy T. Churchwell, Steve J. Kendall, Amy L. Blanchard, Kenneth H. Dunton, Abby N. Powell
2016, Estuaries and Coasts (39) 798-814
Unlike lower latitude coastlines, the estuarine nearshore zones of the Alaskan Beaufort Sea are icebound and frozen up to 9 months annually. This annual freezing event represents a dramatic physical disturbance to fauna living within intertidal sediments. The main objectives of this study were to describe the benthic communities of Beaufort...

Marla H. Stuckey
2016, Scientific Investigations Report 2015-5157
The ability to characterize baseline streamflow conditions, compare them with current conditions, and assess effects of human activities on streamflow is fundamental to water-management programs addressing water allocation, human-health issues, recreation needs, and establishment of ecological flow criteria. The U.S. Geological Survey, through the National Water Census, has developed the...
