John W. Clune, Charles A. Cravotta III
2020, Scientific Investigations Report 2020-5022
Despite the reliance on groundwater by approximately 2.4 million rural Pennsylvania residents, publicly available data to characterize the quality of private well water are limited. As part of a regional effort to characterize groundwater in rural areas of Pennsylvania, samples from 54 domestic wells in Clinton County were collected and...
The role of phosphorus and nitrogen on chlorophyll a: Evidence from hundreds of lakes
Zhongyao Liang, Patricia A. Soranno, Tyler Wagner
2020, Water Research (185)
The effect of nutrients on phytoplankton biomass in lakes continues to be a subject of debate by aquatic scientists. However, determining whether or not chlorophyll a (CHL) is limited by phosphorus (P) and/or nitrogen (N) is rarely considered using a probabilistic method in studies of hundreds of lakes across broad spatial extents....

Importance of accurately quantifying internal loading in developing phosphorus reduction strategies for a chain of shallow lakes
Dale M. Robertson, Matthew W. Diebel
2020, Lake and Reservoir Management (36) 391-411
The Winnebago Pool is a chain of 4 shallow lakes in Wisconsin. Because of high external phosphorus (P) inputs to the lakes, the lakes became highly eutrophic, with much P contained in their sediments. In developing a total maximum daily load (TMDL) for these lakes, it is...
Comparison of storm runoff models for a small watershed in an urban metropolitan area, Albuquerque, New Mexico
Zachary M. Shephard, Kyle R. Douglas-Mankin
2020, Scientific Investigations Report 2020-5058
In order to comply with a current U.S. Environmental Protection Agency watershed-based National Pollutant Discharge Elimination System permit, the City of Albuquerque required a better understanding of the rainfall-runoff processes in its small urban watersheds. That requirement prompted the initiation of the assessment of three existing watershed models that were...
Key components and contrasts in the nitrogen budget across a US-Canadian transboundary watershed
Jiajia Lin, Jana Compton, Chris Clark, Shabtai Bittman, Donna Schwede, Peter Homann, Peter Kiffney, David Hooper, Gary Bahr, Jill S. Baron
2020, Journal of Geophysical Research: Biogeosciences (125)
Watershed nitrogen (N) budgets provide insights into drivers and solutions for groundwater and surface water N contamination. We constructed a comprehensive N budget for the transboundary Nooksack River Watershed (British Columbia, Canada, and Washington, USA) using locally derived data, national statistics, and standard parameters. Feed imports...

Pesticide concentrations associated with augmented flow pulses in the Yolo Bypass and Cache Slough Complex, California
James L. Orlando, Matt De Parsia, Corey J. Sanders, Michelle L. Hladik, Jared Frantzich
2020, Open-File Report 2020-1076
Surface-water and suspended-sediment samples were collected and analyzed by the U.S. Geological Survey for multiple current-use pesticides and pesticide degradates approximately every 2 weeks at up to five sites in the Yolo Bypass and Cache Slough Complex before, during, and after augmented flow pulses in summer and fall 2016 and...
Benthic habitat is an integral part of freshwater Mysis ecology
Jason D. Stockwell, Brian O’Malley, Sture Hansson, Rosie C Chapina, Lars G. Rudstam, Brian Weidel
2020, Freshwater Biology (65) 1997-2009
Diel vertical migration (DVM) is common in aquatic organisms. The trade‐off between reduced predation risk in deeper, darker waters during the day and increased foraging opportunities closer to the surface at night is a leading hypothesis for DVM behaviour.Diel vertical migration behaviour has dominated research and assessment frameworks for Mysis ,...
Linking land and sea through an ecological-economic model of coral reef recreation

2020, Ecological Economics (177)
Coastal zones are popular recreational areas that substantially contribute to social welfare. Managers can use information about specific environmental features that people value, and how these might change under different management scenarios, to spatially target actions to areas of high current or potential value. We explored how snorkelers’ experience would...
Reconstructing the velocity and deformation of a rapid landslide using multiview video
Thomas D Rapstine, Francis K. Rengers, Kate E. Allstadt, Richard M. Iverson, Joel B. Smith, Maciej K. Obryk, M. Logan, M. J. Olsen
2020, Journal of Geophysical Research - Earth Surface (125)
Noncontact measurements of spatially varied ground surface deformation during landslide motion can provide important constraints on landslide mechanics. Here, we present and test a new method for extracting measurements of rapid landslide surface displacement and velocity (accelerations of approximately 1 m/s2) using sequences of stereo images obtained from a pair of...
The importance of explicitly modelling sea-swell waves for runup on reef-lined coasts
Ellen Quataert, Curt D. Storlazzi, Ap van Dongeren, Robert T. McCall
2020, Coastal Engineering (160)
The importance of explicitly modelling sea-swell waves for runup was examined using a 2D XBeach short wave-averaged (surfbeat, “XB-SB”) and a wave-resolving (non-hydrostatic, “XB-NH”) model of Roi-Namur Island on Kwajalein Atoll in the Republic of Marshall Islands. Field observations on water levels, wave heights, and wave runup were used to...
