Explicit consideration of preferential groundwater discharges as surface water ecosystem control points
Martin A. Briggs, Danielle K. Hare
2018, Hydrological Processes (32) 2435-2440
Heterogeneities in sediment and rock permeability induce preferentialgroundwater flow from the scale of pore networks to large basins. Inthe unsaturated zone, preferential flow is frequently conceptualizedas an infiltration process dominated by macropores, resulting in stron-ger delivery of surface‐derived solute...
Using earthquakes, T waves, and infrasound to investigate the eruption of Bogoslof Volcano, Alaska
Aaron Wech, Gabrielle Tepp, John J. Lyons, Matthew M. Haney
2018, Geophysical Research Letters (45) 6918-6925
The 2016‐2017 eruption of Bogoslof volcano, a submarine stratovolcano in the Bering Sea, produced 70 discrete explosive eruptions over 8 months. With no local monitoring data, activity was seismically recorded on nearby islands 50‐100 km away, limiting the detection and resolution of seismic observations. We construct a matched filter catalog...

2018, Open-File Report 2018-1084
As part of a long-term cooperative program to monitor water quality within the Scituate Reservoir watershed, the U.S. Geological Survey in cooperation with the Providence Water Supply Board collected streamflow and water-quality data at the Scituate Reservoir and tributaries. Streamflow and concentrations of chloride and sodium estimated from records of...
Accurate predictions of microscale oxygen barometry in basaltic glasses using V K-edge X-ray absorption spectroscopy: A multivariate approach
Antonio Lanzirotti, M. Darby Dyar, Steve Sutton, Matthew Newville, Elisabet Head, CJ Carey, Molly McCanta, R. Lopaka Lee, Penelope L. King, John Jones
2018, American Mineralogist (103)
Because magmatic oxygen fugacity (fO2) exerts a primary control on the discrete vanadium (V) valence states that will exist in quenched melts, V valence proxies for fO2, measured using X-ray absorption near-edge spectroscopy (XANES), can provide highly sensitive measurements of the redox conditions in basaltic melts. However, published calibrations for basaltic...
Icebergs in the Nordic Seas throughout the Late Pliocene
Yvonne M. Smith, Daniel Hill, Aisling M Dolan, Alan M Haywood, Harry J. Dowsett, Bjorg Risebrobakken
2018, Paleoceanography (33) 318-335
The Arctic cryosphere is changing and making a significant contribution to sea level rise. The Late Pliocene had similar CO2 levels to the present and a warming comparable to model predictions for the end of this century. However, the state of the Arctic cryosphere during the Pliocene remains poorly constrained....

Biodiversity and habitat quantification tools are vital to the operation of this conservation strategy, as they are used to measure the quality and functionality...
The flathead catfish invasion of the Great Lakes
Pamela L. Fuller, Gary Whelan
2018, Journal of Great Lakes Research (44) 1081-1092
A detailed review of historical literature and museum data revealed that flathead catfish were not historically native in the Great Lakes Basin, with the possible exception of a relict population in Lake Erie. The species has invaded Lake Erie, Lake St. Clair, Lake Huron, nearly all drainages in Michigan, and the...
Rapid, remote assessment of Hurricane Matthew impacts using four-dimensional structure-from-motion photogrammetry
Christopher R. Sherwood, Jonathan A. Warrick, Andrew D. Hill, Andrew C. Ritchie, Brian D. Andrews, Nathaniel G. Plant
2018, Journal of Coastal Research (34) 1303-1316
Timely assessment of coastal landforms and structures after storms is important for evaluating storm impacts, aiding emergency response and restoration, and initializing and assessing morphological models. Four-dimensional multiview photogrammetry, also known as structure from motion (4D SfM), provides a method for generating three-dimensional reconstructions of landscapes at two times (before...
Breaching of strike-slip faults and successive flooding of pull-apart basins to form the Gulf of California seaway from ca. 8–6 Ma
Paul J. Umhoefer, Michael H. Darin, Scott E.K. Bennett, Lisa A. Skinner, Rebecca J. Dorsey, Michael E. Oskin
2018, Geology (46) 695-698
The geologic record of the formation of marine basins during continental rifting is uncommonly preserved. Using GIS-based paleotectonic maps, we show that marine basin formation in the Gulf of California–Salton trough oblique rift (Mexico and the United States) occurred in a stepwise manner as crustal thinning lowered elevations within the...

A series of 15 digital flood-inundation maps was developed for a 10.2-mile reach of the Pawtuxet River in the municipalities of West Warwick, Warwick, and Cranston, Rhode Island, by the U.S. Geological Survey (USGS), in cooperation with the Rhode Island Emergency Management Agency and the U.S. Army Corps of Engineers....
Limited nitrate retention capacity in the Upper Mississippi River
Luke C. Loken, John T. Crawford, Mark M. Dornblaser, Robert G. Striegl, Jeffrey N. Houser, Peter A Turner, Emily H. Stanley
2018, Environmental Research Letters (13)
The Mississippi River and other large rivers have the potential to regulate nitrogen export from terrestrial landscapes, and thus mitigate eutrophication in downstream aquatic ecosystems. In large rivers, human-constructed impoundments and connected backwaters may facilitate nitrogen removal; however, the capacity of these features is poorly quantified and...

2018, Veterinary Parasitology (258) 133-137
Toxoplasmosis in marine mammals is epidemiologically and clinically important. Toxoplasma gondii antibodies (by modified agglutination test, cut-off ≥1:25) were detected in serum of 65 of 70 (92.9%) northern sea otters (Enhydra lutris kenyoni) from Washington State, USA. Brains and/or muscles of 44 sea otters were bioassayed in mice (INF-γ knock-out...

Matthew D. De Parsia, James L. Orlando, Megan M. McWayne, Michelle L. Hladik
2018, Data Series 1089
Emergent hypotheses about causes of the pelagic organism decline in the Sacramento–San Joaquin Delta (Delta) indicate that a more complete understanding of the quality of water entering the Delta is needed. Less than half of all pesticides used in the Delta watershed are measured in samples collected for routine monitoring,...
Implicit decision framing as an unrecognized source of confusion in endangered species classification
Jonathan Cummings, Sarah J. Converse, David R. Smith, Steve Morey, Michael C. Runge
2018, Conservation Biology (32) 1246-1254
Legal classification of species requires scientific and values‐based components, and how those components interact depends on how people frame the decision. Is classification a negotiation of trade‐offs, a decision on how to allocate conservation efforts, or simply a comparison of the biological status of a species to a legal standard?...

Groundwater has been a part of the city of Santa Barbara’s water-supply portfolio since the 1800s; however, since the 1960s, the majority of the city’s water has come from local surface water, and the remainder has come from groundwater, State Water Project, recycled water, increased water conservation, and as needed,...
Quantifying variance across spatial scales as part of fire regime classifications
Scholtz Rheinhardt, Samuel D. Fuhlendorf, Sherry A. Leis, Joshua J. Picotte, Dirac Twidwell
2018, Ecosphere (9)
The emergence of large‐scale fire classifications and products informed by remote sensing data has enabled opportunities to include variability or heterogeneity as part of modern fire regime classifications. Currently, basic fire metrics such as mean fire return intervals are calculated without considering spatial variance in a management context. Fire return...

Loraine P. Ketzler, Christopher E. Comer, Daniel J. Twedt
2018, Forest Ecology and Management (417) 40-48
Silvicultural treatments (e.g., selective timber harvests) that are prescribed to promote wildlife habitat are intended to alter the physical structure of forests to achieve conditions deemed beneficial for wildlife. Such treatments have been advocated for management of bottomland hardwood forests on public conservation lands in the Mississippi Alluvial Valley. Although...
