This release consists of vegetation data collected across an environmental gradient at Ten Thousand Islands National Wildlife Refuge (TTI NWR) near Naples, Florida, USA. The refuge is within the impact area of the Picayune Strand Restoration Project (PSRP), a large-scale hydrologic restoration project in southwest Florida that was authorized by the U.S. Congress in 2007. Vegetation transects were located in the following wetland types on the refuge: brackish marsh, salt marsh, and transition marsh. Data from vegetation transects established in nearby areas outside of the PSRP impact area, in Fakahatchee Strand Preserve State Park (FSPSP) and Big Cypress National Preserve (BICY), are also included. The study spanned...

Anaerobic microcosm experiments were conducted in April-May 2018 with PFAS-contaminated soil from a U.S. Army installation (Fort Drum, New York) and simulated groundwater. All microcosms, except for a live sediment control, were amended with perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), and 6:2 fluorotelomer sulfonate (6:2 FtS). Replicate treatments were prepared with and without bioaugmentation with the WBC-2 dehalogenating culture and with and without addition of chlorinated volatile organic compounds (1,1,2,2-tetrachloroethane and trichloroethylene). Two additional treatments were prepared containing granular activated carbon. All microcosms were prepared in duplicate and sacrificed for sampling....

The USGS and Newmont Mining Corp. surveyed 51 cross sections to determine hydraulic characteristics throughout 12 model reaches. The accuracy of the surveyed cross sections is believed to be +/- 0.5 ft. Field surveys included measuring the channel cross section up to the approximate altitude of the highest flood and includes auxiliary channels. Surveyed cross sections generally were at representative locations about every 3 miles along the Humboldt River channel. In areas where long overbank sections occurred, supplemental altitudes were determined from topographic maps in order to extend surveyed parts of cross sections so that each section represented the full width of the floodplain. In this dataset there is...

This USGS data release represents supplemental tabular data for an annual groundwater discharge by evapotranspiration (ET) from areas of spring-fed riparian vegetation, Stump Spring and Hiko Springs, Clark County, Nevada, 2016-18. The raw ET dataset contained multiple data gaps that were simulated and gap-filled with the water-level model utility in SeriesSEE, a USGS developed Microsoft Excel® addin. Continuous time-series data, including net radiation, sensible-heat flux, latent-heat flux, and ground-heat flux, from before and after the data gap(s) were used to simulate turbulent fluxes with multivariate regressions and the gramma transform, used for latent heat gaps after precipitation events. ET data were gap...

Over 4,400 large scale commercial solar facilities are in operation in the United States as of December, 2021, representing over 60 gigawatts of electric power capacity; of these, over 3,900 are ground-mounted with capacities of 1MW or more, specified as large scale solar photovoltaic (LSPV) facilities. LSPV ground-mounted installations continue to grow, with over 400 projects coming online in 2021 alone. Currently, a comprehensive, publicly available georectified data describing the locations and spatial footprints of these facilities does not exist. Analysts from the US Geological Survey and Lawrence Berkeley National Laboratory collaborated to develop and release the United States Large Scale Solar Photovoltaic...

Hurricane Maria brought intense rainfall and caused widespread landsliding throughout Puerto Rico during September 2017. Previous detailed landslide inventories following the hurricane include Bessette-Kirton et al. (2017, 2019). Here we continue that work with an in-depth look at two areas in San Lorenzo, which is a municipality in the east-central part of the main island. To study a characteristic sample of landslides in San Lorenzo, we mapped all visible landslides in two physiographically diverse areas, but all within the San Lorenzo Formation. We used aerial imagery collected between 9-15 October 2017 (Quantum Spatial, Inc., 2017) to map landslide source and runout areas, and 1-m-resolution pre-event and post-event...

Growth potential of redband trout (Oncorhynchus mykiss newberri) was simulated across 175 river segments in the Donner und Blitzen River basin for water years 1980 through 2021 using a bioenergetics model. A previously published framework for assessing climate vulnerability of redband trout was used to simulate the growth potential of redband trout in relation to constraints on body size, physiological responses linked to variable thermal regimes, and variation in physiological adaptive capacity. For body size, three starting sizes of redband trout, 10 g, 50 g, and 150 g, were used for each day of the simulations. For thermal regimes, daily stream temperatures were estimated from PRISM. To account for variation...

The decline of the iconic monarch butterfly in North America has motivated research on the impacts of land use and land cover (LULC) change and climate variability on monarch habitat and population dynamics. We investigated spring and fall trends in LULC, milkweed and nectar resources over a 20-year period, and ~30 years of climate variables in Mexico and Texas, a key region supporting spring and fall migration during monarchs annual life cycle. We estimated a 2.9% decline in milkweed in Texas, but little to no change in Mexico. Fall and spring nectar resources declined <1% in both countries. Vegetation greenness increased in both the fall and spring in Mexico while the other climate variables, for both countries,...

The U.S. Geological Survey, in cooperation with the Tennessee Department of Transportation, conducted an investigation of acid-rock drainage from road cuts in Tennessee during 2014-2015. The Devonian Chattanooga Shale contains disseminated pyrite and is a primary producer of acid-rock drainage (ARD) in Tennessee. One objective of the overall investigation was to attenuate ARD by manipulating the indigenous microbial community through different treatment injections. The scope of the study included establishing flow-through microcosms constructed with shale from the Chattanooga Shale formation rich in pyrite collected from an ARD site in Middle Tennessee. The microcosms were subjected to various treatments and evaluations...

A new 30-m spatial resolution global shoreline vector (GSV) was developed from annual composites of 2014 Landsat satellite imagery. The semi-automated classification of the imagery was accomplished by manual selection of training points representing water and non-water classes along the entire global coastline. Polygon topology was applied to the GSV, and the resulting polygons were mapped into four size classes of islands: Continental Mainlands, Big Islands (greater than 1 km2), Small Islands (less than or equal to 1 km2 and greater than or equal to 0.0036 km2), and Very Small Islands (less than 0.0036 km2).
