Calcium, magnesium and total dissolved solids data as well as modeled salinity and mass balance estimates for Lake Powell, 1952-2017

These data were compiled to quantify the role of Lake Powell in modulating salinity and reducing overall salt flux from the Upper Colorado River Basin downstream.  In addition, these data were used to infer summertime calcite precipitation in Lake Powell (the major proposed sink for salt within the system).  The Lake Powell Calcium Magnesium data contains summertime surface water calcium and magnesium concentrations along three transects that span the two major inflows to Lake Powell and the region of Lake Powell closest to the dam.  The Modeled Salinity data was used to compare measured total dissolved solid concentrations at Lees Ferry to the instantaneous flow-weighted concentration of total dissolved solid entering the reservoir at any given time.  The NWIS-Weighted Inflow Salinity data was used to compare total dissolved salt concentrations made by the Lake Powell Water Quality Monitoring Program to those inferred from upstream gaged sites contained in the National Water Information System.  The WRTDS-Output Mass Balance data presents annual mass balance estimates for total dissolved solids, sulfate, bicarbonate, calcium, and chloride in Lake Powell including raw results from Weighted Regressions on Time, Discharge and Season (WRTDS) modeling and estimates of changes in annual reservoir storage.

Anchored hybrid enrichment in Potamilus mussels

Freshwater mussels are a species-rich group with biodiversity patterns shaped by life history strategies that include an obligate parasitic larval stage. Anchored hybrid enrichment (AHE) and ancestral character reconstruction (ACR) revealed convergence of life history strategies involving larval morphologies that reduce size to increase fecundity and require growth during encapsulation to increase survival post-metamorphosis.

Data on interannual variability of seed production, nutrient, and weather for 219 plant species

We calculated estimates describing interannual variation in seed production for series of long-term seed or fruit production in 219 plant species.  For each plant species, we compiled estimates of foliar nutrient concentrations as well as productivity and weather at the site of observation.  Data was compiled in order to test whether interannual variation in seed production was greater in species with lower foliar nutrient concentrations or greater nutrient imbalances.

Stand density and climate data in the Taylor Woods study area (Fort Valley Experimental Forest) on the Colorado Plateau in Northern Arizona, 1961-2011

These data were compiled for research pertaining to the effects of stand density on growth rates in semi-arid forests. Increasing heat and aridity in coming decades is expected to negatively impact tree growth and threaten forest sustainability in dry areas. Maintaining low stand density has the potential to mitigate the negative effects of increasingly severe droughts by minimizing competitive intensity. By inspecting growth rates and the climate and soil moisture conditions that drive these growth rates we can understand better the positive effects of reducing stand density and the specific dynamics that are beneficial to growth.

Direct Trace Element Determination in Oil and Gas Produced Waters with Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES): Advantages of High Salinity Tolerance (2019)

Waters co-produced during petroleum extraction are the largest waste stream from oil and gas development. Reuse or disposal of these waters is difficult due both to their high salinities, which can greatly exceed 35 g/L (seawater equivalent), and also the sheer volume of wastewater generated, which is estimated at nearly 900 billion gallons per year across the United States. Beyond disposal concerns, produced water may also represent a possible source of valuable mineral commodities. While an understanding of the trace element composition of produced water is required for evaluating the associated resource and waste potential of these materials, measuring trace elements in high salinity brines is challenging due to the dilution requirements of typical methods. Alternatively, inductively coupled plasma-optical emission spectrometry (ICP-OES) has shown promise as being capable of direct measurements of trace elements within produced waters with minimal dilution. Here we evaluate direct ICP-OES trace element quantification in produced waters through detection and quantification for 17 select trace elements (As, Al, Ba, Be, Cd, Cr, Co, Cu, Hg, Mo, Ni, Pb, Rb, Sb, U, V, and Zn) from 15 produced water samples. The produced waters range in salinity from 17 to 370 g/L and originate from the Eagle Ford, Marcellus, Middle Bakken/Three Forks, Wolfcamp/Cline, and Utica/Point Pleasant reservoirs. The ICP-OES results are compared against trace element levels determined using inductively coupled plasma-mass spectrometry (ICP-MS) from the same samples. Our results demonstrate the potential of an ICP-OES approach for the direct analysis of trace components from high salinity aqueous solutions with minimal dilution and provide additional trace element concentrations for waters from several important U.S. petroleum-generating continuous reservoirs where available data is sparse.

Common murres collected in Alaska from January 1, 2015 through December 31, 2016 and shipped to USGS National Wildlife Health Center for cause of death determination

About 62,000 dead or dying common murres (Uria aalge), the trophically dominant fish-eating seabird of the North Pacific, washed ashore between summer 2015 and spring 2016 on beaches from California to Alaska. Most birds were severely emaciated and, so far, no evidence for anything other than starvation was found to explain this mass mortality. Three-quarters of murres were found in the Gulf of Alaska and the remainder along the West Coast. Total mortality was estimated at 0.54 to 1.2 million birds. About two-thirds of murres killed were adults, a substantial blow to breeding populations. Additionally, 22 complete reproductive failures were observed at multiple colonies region-wide during (2015) and after (2016-2017) the mass mortality event. Die-offs and breeding failures occur sporadically in murres, but the magnitude, duration and spatial extent of this die-off, associated with multi-colony and multi-year reproductive failures, is unprecedented and astonishing. These events co-occurred with the most powerful marine heatwave on record that persisted through 2014-2016 and created an enormous volume of ocean water (the “Blob”) from California to Alaska with temperatures that exceeded average by 2-3 standard deviations. Other studies indicate that this prolonged heatwave reduced primary production and restructured zooplankton communities in favor of lower-calorie species, while it simultaneously increased metabolically driven food demands of ectothermic forage fish. In response, forage fish quality and quantity diminished. Similarly, large ectothermic groundfish increased their demand for forage fish, resulting in greater top-predator demands for diminished forage fish resources. We hypothesize that these bottom-up and top-down forces created an “ectothermic vise” on forage species leading to their system-wide scarcity and resulting in mass mortality of murres and many other fish, bird and mammal species in the region during 2014-2017. This was the largest climate-induced perturbation of North Pacific pelagic food webs since the 1976 regime shift.

Lake Hermitage Marsh Creation (BA-0042): 2016 land-water classification

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Lake Hermitage Marsh Creation (BA-0042) project for 2016. This data is used as a basemap land-water classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their project boundary. To better evaluate the effectiveness of restoration efforts, a land-water classification is performed on specific CWPPRA sites to help assess landscape changes.

Voice and data telecommunications restoration curves for 17 counties affected by the April 18, 2018, M7.0 HayWired earthquake scenario mainshock

These data are a series of telecommunications voice and data restoration percentages for 17 counties affected by the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data for telecommunications demand served are derived from residual network capacity based on potential hazard information (for example, ground shaking and liquefaction), assumptions about dependence on electric power restoration, and assumptions about network congestion caused by demand surge. Various resilience cases pertain to assumptions about the presence of backup power (for example, batteries or generators), ability to truck in fuel and portable equipment (for example, cells on wheel or gensets with fuel), and reductions in surges in demand for voice and data services after the mainshock. The model calculates demand served at different time steps (0, 1, 2, 3, 4, 5, 6, 7, 9, 30, and 90 days) following the HayWired scenario mainshock. The results are presented as a table, summarized by county and resilience case (with or without demand surge as a factor).
The counties covered in this analysis include the following: Alameda, Contra Costa, Marin, Merced, Monterey, Napa, Sacramento, San Benito, San Francisco, San Joaquin, San Mateo, Santa Clara, Santa Cruz, Solano, Sonoma, Stanislaus, and Yolo.
This comma-delimited .CSV dataset was developed and intended for use in standalone spreadsheet or database applications (such as Microsoft Excel).

Invasive plant cover in the Mojave Desert, 2009 - 2013 (Version 2.0, March 2021)

We assessed the impacts of co-occurring invasive plant species on fire regimes and postfire native communities in the Mojave Desert, western USA by analyzing the distribution and co-occurrence patterns of three invasive annual grasses known to alter fuel conditions and community structure:  Red Brome (Bromus rubens),  Cheatgrass (Bromus tectorum), and Mediterranean grass (Schismus spp.: Schismus arabicus and Schismus barbatus), and an invasive forb, red stemmed filaree (Erodium cicutarium) which can dominate postfire sites. We developed species distribution models (SDMs) for each of the four taxa and analyzed field plot data to assess the relationship between invasives and fire frequency, years postfire, and the impacts on postfire native herbaceous diversity.
The data include: 
(1) A shapefile of the Mojave Desert that was used as our study area boundary (MojaveEcoregion_TNS_UTM83.shp). The original shapefile was obtained from NatureServe in 2009.
(2) Two Comma Separated Values (CSV) files with the geographic location (Survey Plot Information.csv) and abundance (percent cover) of the four invasive taxa (Cover Measurements.csv) throughout the Mojave Desert.
(3) Four Tagged-Interchange Format (TIF) raster datasets representing the SDMs.

Shorelines of the Delmarva North coastal region from Cape Henlopen, Delaware to the southern end of Assateague Island, Virginia, used in shoreline change analysis (DelmarvaN_shorelines.shp)

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.  
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.
