Kyle R. Douglas-Mankin, C. David Moeser
2019, Scientific Investigations Report 2019-5022
The Precipitation-Runoff Modeling System (PRMS) is widely used to simulate the effects of climate, topography, land cover, and soils on landscape-level hydrologic responses and streamflow. The U.S. Geological Survey (USGS), in cooperation with the New Mexico Department of Homeland Security and Emergency Management, developed procedures to apply the PRMS model...

David H. Ward, Courtney L. Amundson
2019, Open-File Report 2019-1042
A lagoon-wide, point-sampling survey of eelgrass (Zostera marina) abundance was conducted in Izembek Lagoon, Alaska, August 7–16, 2018, the ninth year of annual surveys (2007–11, 2015–18).

Wildfire as a catalyst for hydrologic and geomorphic change
Francis K. Rengers
2019, Environmental Science
Wildfire has been a constant presence on the Earth since at least the Silurian period, and is a landscape-scale catalyst that results in a step-change perturbation for hydrologic systems, which ripples across burned terrain, shaping the geomorphic legacy of watersheds. Specifically, wildfire alters two key landscape properties: (1) overland flow,...

Debra A. Willard, Timme H Donders, Tammo Reichgelt, David R Greenwood, Francien Peterse, Francesca Sangiorgi, Appy Sluijs, Stefan Schouten
2019, Global and Planetary Change (178) 139-152
Early Eocene global climate was warmer than much of the Cenozoic and was punctuated by a series of transient warming events or ‘hyperthermals’ associated with carbon isotope excursions when temperature increased by 4–8° C. The Paleocene-Eocene Thermal Maximum (PETM, ~55 Ma) and Eocene Thermal Maximum 2 (ETM2, 53.5 Ma) hyperthermals...
Drivers and impacts of water level fluctuations in the Mississippi River delta: Implications for delta restoration

Jennifer L. Lewicki, William C. Evans, Emily K. Montgomery-Brown, Margaret T. Mangan, John King, Andrew G. Hunt
2019, Geophysical Research Letters (46) 4636-4644
Mammoth Mountain, California, has exhibited unrest over the past ~30 years, characterized by seismicity over a broad range of depths, elevated 3He/4He ratios in fumarolic gas, and large-scale diffuse CO2 emissions. This activity has been attributed to magmatic intrusion, but minimal ground deformation and the presence of a shallow crustal gas reservoir...

Frederick Pollitz, Charles Wicks, William L. Yeck, James E. Evans
2019, Bulletin of the Seismological Society of America (109) 875-887
The 2 September 2017 M 5.3 Sulphur Peak, Idaho, earthquake is one of the largest earthquakes in southern Idaho since the 1983 M 6.9 Borah Peak earthquake. It was followed by a vigorous aftershock sequence for nearly two weeks that included five events above M 4.5. The coseismic and early postseismic deformation was...

2019, Scientific Reports (9)
The use of single nucleotide polymorphism (SNP) arrays to generate large SNP datasets for comparison purposes have recently become an attractive alternative to other genotyping methods. Although most SNP arrays were originally developed for domestic organisms, they can be effectively applied to wild relatives to obtain...

Neil Kamal Ganju, Zafer Defne, Tracy Elsey Quirk, Julia M. Moriarty
2019, Limnology and Oceanography (124) 1265-1277
Tidal wetland fluxes of particulate organic matter and carbon (POM, POC) are important terms in global budgets but remain poorly constrained. Given the link between sediment fluxes and wetland stability, POM and POC fluxes should also be related to stability. We measured POM and POC fluxes in...

Shallow structure and geomorphology along the offshore northern San Andreas Fault, Tomales Point to Fort Ross, California
Samuel Johnson, Beeson Jeffrey W.
2019, Bulletin of the Seismological Society of America (109) 833-854
We mapped a poorly documented 35-km-long section of the northern San Andreas fault zone (NSAF) between Tomales Point and Fort Ross, California. Mapping is largely based on high-resolution seismic-reflection profiles (38 fault crossings), multibeam bathymetry, and onshore geology. NSAF strike in this section is nearly parallel to plate motion, characterized...
Reservoir diel water quality patterns relative to riparian shade
Leandro E. Miranda, C.D. Raines
2019, Lake and Reservoir Management (35) 148-155
Investigations into the effects of riparian shade on water quality have focused on streams, with less emphasis on natural lakes, and almost no attention given to reservoirs. In view of this gap, our objective was to assess diel water quality patterns in the nearshore zone of a reservoir and test...

Multiscale habitat factors explain variability in stream fish occurrence in the Ozark Highlands ecoregion, USA
Robert Mollenhauer, Yan Zhou, Shannon K. Brewer
2019, Copeia (107) 219-231
The dynamic, multiscale nature of stream systems makes it challenging to establish basic ecological principles to guide stream fish conservation and management. For example, finer-scale instream habitat is often constrained by coarser-scale characteristics driving observed species distributions. Additionally, instream environmental variability can result in patchy species distributions within general upstream–downstream...

Aluminum mobility in mildly acidic mine drainage: Interactions between hydrobasaluminite, silica and trace metals from the nano to the meso-scale
Manuel A. Caraballo, Richard Wanty, Philip Verplanck, Leonardo Navarro-Valdivia, Carlos Ayora, Michael Hochella
2019, Chemical Geology (519) 1-10
Aluminum precipitates control the hydrochemistry and mineralogy of a broad variety of environments on Earth (e.g., acid mine drainage, AMD, coastal wetlands, boreal and alpine streams, tropical acid sulfate soils, laterites and bauxites, …). However, the geochemical and mineralogical processes controlling Al (and other associated metals and metalloids) transport and removal in those environments...
