Groundwater-level and storage-volume changes in the Equus Beds aquifer near Wichita, Kansas, predevelopment through January 2015
Joshua A. Whisnant, Cristi V. Hansen, Patrick J. Eslick
2015, Scientific Investigations Report 2015-5121
Development of the Wichita well field began in the 1940s in the Equus Beds aquifer to provide the city of Wichita, Kansas, a new water-supply source. After development of the Wichita well field began, groundwater levels began to decline. Extensive development of irrigation wells that began in the 1970s also...
Olistostrome shed eastward from the Antler orogenic forebulge, Bisoni-McKay area, Fish Creek Range, central Nevada
Forrest G. Poole, Charles Sandberg
2015, Book chapter, Unusual central Nevada geologic terranes produced by Late Devonian antler orogeny and Alamo impact
The Bisoni-McKay area, a structurally isolated, fault-bounded horst, offset eastward at the south end of the Fish Creek Range, displays a geologic terrane that is previously unrecorded in Nevada, and perhaps elsewhere in North America. This unique terrane is an olistostrome that was shed eastward by listric faulting from the...
Regional and temporal differences in nitrate trends discerned from long-term water quality monitoring data
Edward G. Stets, Valerie J. Kelly, Charles G. Crawford
2015, Journal of the American Water Resources Association (51) 1394-1407
Riverine nitrate (NO3) is a well-documented driver of eutrophication and hypoxia in coastal areas. The development of the elevated river NO3 concentration is linked to anthropogenic inputs from municipal, agricultural, and atmospheric sources. The intensity of these sources has varied regionally, through time, and in response to multiple causes such as...
Suburban watershed nitrogen retention: Estimating the effectiveness of stormwater management structures
Benjamin J. Koch, Catherine M. Febria, Roger M. Cooke, Jacob D. Hosen, Matthew E. Baker, Abigail R. Colson, Solange Filoso, Katharine Hayhoe, J. V. Loperfido, Anne M.K. Stoner, Margaret A. Palmer
2015, Elementa: Science of the Anthropocene
Excess nitrogen (N) is a primary driver of freshwater and coastal eutrophication globally, and urban stormwater is a rapidly growing source of N pollution. Stormwater best management practices (BMPs) are used widely to remove excess N from runoff in urban and suburban areas, and are expected to perform under a...
Spatial and temporal movement dynamics of brook Salvelinus fontinalis and brown trout Salmo trutta
L.A. Davis, Tyler Wagner, Meredith L. Barton
2015, Environmental Biology of Fishes (98) 2049-2065
Native eastern brook trout Salvelinus fontinalis and naturalized brown trout Salmo trutta occur sympatrically in many streams across the brook trout’s native range in the eastern United States. Understanding within- among-species variability in movement, including correlates of movement, has implications for management and conservation. We radio tracked 55 brook trout...

Reconstructing the growth and decay of palaeo-ice sheets is critical to understanding mechanisms of global climate change and associated sea-level fluctuations in the past, present and future. The significance of palaeo-ice sheets is further underlined by the broad range of disciplines concerned with reconstructing their behaviour, many of which have...

2015, Fact Sheet 2015-3064
An important and sometimes overlooked aspect of contemporary natural gas exploration, development, and delivery activities is the geographic profile and spatial footprint that these activities have on the land surface. The function of many ecosystems and the goods and services they provide, in large part, are the result of their...

2015, Earth and Planetary Science Letters (426) 167-175
We present two-dimensional P-wave velocity structure along two wide-angle ocean bottom seismometer profiles from the Aleutian basin in the Bering Sea. The basement here is commonly considered to be trapped oceanic crust, yet there is a change in orientation of magnetic lineations and gravity features within the basin that might...

P. J. Bartlein, M. E. Edwards, Steven W. Hostetler, Sarah Shafer, P. M. Anderson, L. B Brubaker, A. V Lozhkin
2015, Climate of the Past (11) 1197-1222
Arctic land-cover changes induced by recent global climate change (e.g., expansion of woody vegetation into tundra and effects of permafrost degradation) are expected to generate further feedbacks to the climate system. Past changes can be used to assess our understanding of feedback mechanisms through a combination of process modeling and...
National assessment of nor’easter-induced coastal erosion hazards: mid- and northeast Atlantic coast
Justin J. Birchler, P. Soupy Dalyander, Hilary F. Stockdon, Kara S. Doran
2015, Open-File Report 2015-1154
Beaches serve as a natural buffer between the ocean and inland communities, ecosystems, and natural resources. However, these dynamic environments move and change in response to winds, waves, and currents. During extreme storms, changes to beaches can be great, and the results are sometimes catastrophic. Lives may be lost, communities...

S.P. Finn, Lee M. Liberty, Peter J. Haeussler, Thomas L. Pratt
2015, Bulletin of the Seismological Society of America (105) 2343-2353
We present new marine seismic‐reflection profiles and bathymetric maps to characterize Holocene depositional patterns, submarine landslides, and active faults beneath eastern and central Prince William Sound (PWS), Alaska, which is the eastern rupture patch of the 1964 Mw 9.2 earthquake. We show evidence that submarine landslides, many of which are...

E. Randolph Mcfarland
2015, Scientific Investigations Report 2015-5117
A conceptual framework synthesizes previous studies to provide an understanding of conditions, processes, and relations of saltwater to groundwater withdrawal in the Virginia Coastal Plain aquifer system. A strategy for monitoring saltwater movement is based on spatial relations between the saltwater-transition zone and 612 groundwater-production wells that were regulated during...

Robin E. Russell, Wayne E. Thogmartin, Richard A. Erickson, Jennifer A. Szymanski, Karl Tinsley
2015, Ecological Modelling (314) 111-117
White-nose syndrome (WNS) was first detected in North American bats in New York in 2006. Since that time WNS has spread throughout the northeastern United States, southeastern Canada, and southwest across Pennsylvania and as far west as Missouri. Suspect WNS cases have been identified in Minnesota and Iowa, and the...
The Centennial Trends Greater Horn of Africa precipitation dataset
Chris Funk, Sharon E. Nicholson, Martin F. Landsfeld, Douglas Klotter, Pete J. Peterson, Laura Harrison
2015, Scientific Data (2)
East Africa is a drought prone, food and water insecure region with a highly variable climate. This complexity makes rainfall estimation challenging, and this challenge is compounded by low rain gauge densities and inhomogeneous monitoring networks. The dearth of observations is particularly problematic over the past decade, since the number...
