Assessing mercury distribution using isotopic fractionation of mercury processes and sources adjacent and downstream of a legacy mine district in Tuscany, Italy
Mercury (Hg) concentrations and isotopic compositions in a range of sample types collected from the legacy Abbadia San Salvatore Mine (ASSM) area were used to evaluate the distribution of Hg in the region. The district generated more than 100,000 metric tons of Hg releasing extensive amounts of gaseous Hg emissions and producing large amounts of...
Pribil, Michael; Rimondi, Valentina; Costagliola, Pilario; Lattanzi, Pierfranco; Rutherford, Danny Monazite and cassiterite Usingle bondPb dating of the Abu Dabbab rare-metal granite, Egypt: Late Cryogenian metalliferous granite magmatism in the Arabian-Nubian Shield
The Abu Dabbab rare-metal granite in the Eastern Desert of Egypt is a highly-evolved alkali-feldspar granite with transitional magmatic-hydrothermal features. Extreme geochemical fractionation and the associated significant TaSn resource make the Abu Dabbab intrusion an important feature in the metallogenic evolution of the Arabian-Nubian Shield....
Lehmann, Bernd; Zoheir, Basem; Neymark, Leonid A.; Zeh, Armin; Emam, Ashraf; Radwan, Abdelhady; Zhang, Rongqing; Moscati, Richard J. Practical limitations of Earthquake Early Warning
Earthquake Early Earning (EEW) entails detection of initial earthquake shaking and rapid estimation and notification to users prior to imminent, stronger shaking. EEW is coming to the U.S. West Coast. But what are the technical and social challenges to delivering actionable information on earthquake shaking before it arrives? Although there will...
Wald, David J. USGS “Did You Feel It?” — Science and lessons from twenty years of citizen science-based macroseismology
The U.S. Geological Survey (USGS) “Did You Feel It?” (DYFI) system is an automatic method for rapidly collecting macroseismic intensity data from Internet users’ shaking and damage reports and for generating intensity maps immediately following felt earthquakes. DYFI has been in operation for nearly two decades (1999-2019) in the United States,...

Assessment of tight-gas resources in the Grand Erg/Ahnet Province of Algeria, 2019
Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean resources of 30.5 trillion cubic feet of tight gas in the Grand Erg/Ahnet Province of Algeria.
Brownfield, Michael E.; Schenk, Christopher J.; Mercier, Tracey J.; Tennyson, Marilyn E.; Woodall, Cheryl A.; Finn, Thomas M.; Le, Phuong A.; Pitman, Janet K.; Drake, Ronald M.; Gaswirth, Stephanie B.; Leathers-Miller, Heidi M. How processing methodologies can distort and bias power spectral density estimates of seismic background noise
Power spectral density (PSD) estimates are widely used in seismological studies to characterize background noise conditions, assess instrument performance, and study quasi‐stationary signals that are difficult to observe in the time domain. However, these studies often utilize different processing techniques, each of which can inherently bias the...
Anthony, Robert E.; Ringler, Adam T.; Wilson, David C.; Bahavar, Manochehr; Koper, Keith D. Testing ecosystem accounting in the United States: A case study for the Southeast
Ecosystem accounts, as formalized by the System of Environmental-Economic Accounting Experimental Ecosystem Accounts (SEEA EEA), have been compiled in a number of countries, yet there have been few attempts to develop them for the U.S. We explore the potential for U.S. ecosystem accounting by compiling ecosystem extent, condition, and ecosystem...

Assessing geohazards to the Denali National Park road with geologic mapping
Denali National Park (DENA) is home to iconic and breathtaking landscapes surrounding the tallest mountain range in North America, the Alaska Range. The park, which covers 6 million acres, is a major draw for tourism and recreation, making it an important economic engine for central Alaska. However, the geologic forces that created the beautiful,...
Hudson, Adam M.; Ruleman, Chester A.; Capps, Denny M Depth-dependent soil mixing persists across climate zones
Soil mixing over long (>102 y) timescales enhances nutrient fluxes that support soil ecology, contributes to dispersion of sediment and contaminated material, and modulates fluxes of carbon through Earth’s largest terrestrial carbon reservoir. Despite its foundational importance, we lack robust understanding of the rates and patterns of...
Gray, Harrison J.; Keen-Zebert, Amanda; Furbish, David; Tucker, Gregory E.; Mahan, Shannon A. Runoff-initiated post-fire debris flow Western Cascades, Oregon
Wildfires dramatically alter the hydraulics and root reinforcement of soil on forested hillslopes, which can promote the generation of debris flows. In the Pacific Northwest, post-fire shallow landsliding has been well documented and studied, but the potential role of runoff-initiated debris flows is not well understood and only one previous to...
Wall, Sara; Roering, J.J.; Rengers, Francis K. Learning from real-world experience to understand renewable energy impacts to wildlife
The project team sought to use real-world data to understand adverse effects to wildlife of renewable energy production that is critical to meeting California’s climate and clean energy goals. The project had three main components. First, a systematic literature review studied 20 peer-reviewed publications and 612 reports from other nonreviewed...

This white paper provides the results of a survey by members of the NGWA Groundwater Modeling Advisory Panel to assess the use of uncertainty analysis in groundwater modeling.The objective of the survey was to improve understanding of the use of uncertainty analysis in practical groundwater modeling projects subject to real-world constraints, such...

Invasive brown treesnake
Brown treesnakes were a major contributor to the loss of nine of 11 native forest birds on Guam.
Rainstorms can be localized or widespread.
A localized heavy summer rainstorm in Colorado.
Here is a classic rainstorm during the summer, as that is when more localized storms occur. Other rain events are more "frontal" in nature, with large formations of featureless and uniform nimbostratus types of clouds bringing precipitation over a large area. But often you see a landscape similar to
