The Delaware River Basin (DRB) was selected as a Focus Area Study in 2011 by the U.S. Geological Survey (USGS) as part of the USGS National Water Census. The National Water Census is a USGS research program that focuses on national water availability and use and then develops new water...
The 3D Elevation Program and America's infrastructure
Vicki Lukas, Carswell
2016, Fact Sheet 2016-3093
Infrastructure—the physical framework of transportation, energy, communications, water supply, and other systems—and construction management—the overall planning, coordination, and control of a project from beginning to end—are critical to the Nation’s prosperity. The American Society of Civil Engineers has warned that, despite the importance of the Nation’s infrastructure, it is in...

Thomas D. Lorenson, Jens Greinert, Richard B. Coffin
2016, Limnology and Oceanography (61) S300-S323
Methane concentration and isotopic composition was measured in ice-covered and ice-free waters of the Arctic Ocean during eleven surveys spanning the years of 1992-1995 and 2009. During ice-free periods, methane flux from the Beaufort shelf varies from 0.14 to 0.43 mg CH4 m-2 day-1. Maximum fluxes from localized areas of...
Stakeholder views of management and decision support tools to integrate climate change into Great Lakes Lake Whitefish management
Abigail J. Lynch, William W. Taylor, Aaron M. McCright
2016, Fisheries (41) 644-652
Decision support tools can aid decision making by systematically incorporating information, accounting for uncertainties, and facilitating evaluation between alternatives. Without user buy-in, however, decision support tools can fail to influence decision-making processes. We surveyed fishery researchers, managers, and fishers affiliated with the Lake Whitefish Coregonus clupeaformis fishery in the 1836...

This chapter serves as an overview of the streamflow data collection process. Readers with the need for the detailed information on...
Widespread kelp-derived carbon in pelagic and benthic nearshore fishes
Vanessa R. von Biela, Seth D. Newsome, James L. Bodkin, Gordon H. Kruse, Christian E. Zimmerman
2016, Estuarine, Coastal and Shelf Science (181) 364-374
Kelp forests provide habitat for diverse and abundant fish assemblages, but the extent to which kelp provides a source of energy to fish and other predators is unclear. To examine the use of kelp-derived energy by fishes we estimated the contribution of kelp- and phytoplankton-derived carbon using carbon (δ13C) and...
Impacts of shore expansion and catchment characteristics on lacustrine thermokarst records in permafrost lowlands, Alaska Arctic Coastal Plain
Josefine Lenz, Benjamin M. Jones, Sebastian Wetterich, Rik Tjallingii, Michael Fritz, Christopher D. Arp, Natalia Rudaya, Guido Grosse
2016, arktos (2)
Arctic lowland landscapes have been modified by thermokarst lake processes throughout the Holocene. Thermokarst lakes form as a result of ice-rich permafrost degradation, and they may expand over time through thermal and mechanical shoreline erosion. We studied proximal and distal sedimentary records from a thermokarst lake located on the Arctic...

Carolyn D. Ruppel, Bruce M. Herman, Laura L. Brothers, Patrick E. Hart
2016, Geochemistry, Geophysics, Geosystems (17) 4333-4353
Borehole logging data from legacy wells directly constrain the contemporary distribution of subsea permafrost in the sedimentary section at discrete locations on the U.S. Beaufort Margin and complement recent regional analyses of exploration seismic data to delineate the permafrost's offshore extent. Most usable borehole data were acquired on a ∼500...
Subsea ice-bearing permafrost on the U.S. Beaufort Margin: 1. Minimum seaward extent defined from multichannel seismic reflection data
Laura L. Brothers, Bruce M. Herman, Patrick E. Hart, Carolyn D. Ruppel
2016, Geochemistry, Geophysics, Geosystems (17) 4354-4365
Subsea ice-bearing permafrost (IBPF) and associated gas hydrate in the Arctic have been subject to a warming climate and saline intrusion since the last transgression at the end of the Pleistocene. The consequent degradation of IBPF is potentially associated with significant degassing of dissociating gas hydrate deposits. Previous studies interpreted...

The salt fraction in permafrost soils/sediments of the McMurdo Dry Valleys (MDV) of Antarctica can be used as a proxy for cold desert geochemical processes and paleoclimate reconstruction. Previous analyses of the salt fraction in MDV permafrost soils have largely been conducted in coastal regions where permafrost soils are variably...

2016, Earthquake Spectra (32) 497-522
The 11 March 2011 M 9.0 Tohoku earthquake generated long-duration shaking that propagated hundreds of kilometers from the epicenter and affected tall buildings in urban areas several hundred kilometers from the epicenter of the main shock. Recorded responses show that tall buildings were affected by long-period motions. This study presents...

Yong Zhang, Christopher T. Green, Eric M. LaBolle, Roseanna M. Neupauer, Hong-Guang Sun
2016, Water Resources Research (52) 8561-8577
Spatiotemporal Fractional-Derivative Models (FDMs) have been increasingly used to simulate non-Fickian diffusion, but methods have not been available to define boundary conditions for FDMs in bounded domains. This study defines boundary conditions and then develops a Lagrangian solver to approximate bounded, one-dimensional fractional diffusion. Both the zero-value and non-zero-value Dirichlet,...
A-DROP: A predictive model for the formation of oil particle aggregates (OPAs)
Lin Zhao, Michel C. Boufadel, Xiaolong Geng, Kenneth Lee, Thomas King, Brian H. Robinson, Faith A. Fitzpatrick
2016, Marine Pollution Bulletin (106) 245-259
Oil–particle interactions play a major role in removal of free oil from the water column. We present a new conceptual–numerical model, A-DROP, to predict oil amount trapped in oil–particle aggregates. A new conceptual formulation of oil–particle coagulation efficiency is introduced to account for the effects of oil stabilization by particles,...

Daniel E. Clark, Stephen DeStefano, Kenneth G. MacKenzie, Kiana K. G. Koenen, Jillian J. Whitney
2016, Journal of Wildlife Management (80) 708-719
Gulls (Larus spp.) commonly roost in large numbers on inland and coastal waters, yet there is little information on how or where gulls choose sites for roosting. Roost site selection can lead to water quality degradation or aviation hazards when roosts are formed on water supply reservoirs or are close...

Rising atmospheric [CO2], ca, is expected to affect stomatal regulation of leaf gas-exchange of woody plants, thus influencing energy fluxes as well as carbon (C), water, and nutrient cycling of forests. Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO2],...
