Soil frost measurements have been made at Sleepers River Research Watershed starting in 1983. Measurements were made by U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory from 1983 to 1993, followed by the U.S. Geological Survey from 1993 to the present. Measurements started at 5 sites and has increased to 10 sites. Sites range in elevation from 225 to 670 meters and are in a mix of field and forest types. Soil frost measurements are made with tubes filled with methylene blue solution; on freezing, the methylene blue remains in the liquid phase, yielding clear ice that marks the depth of soil frost (Ricard and others, 1976). Soil frost measurements typically are made 2 to 4 times a month...
The U.S. Geological Survey (USGS), in cooperation with the Puerto Rico Environmental Quality Board, has compiled a series of geospatial datasets for Puerto Rico to be implemented into the USGS StreamStats application (https://streamstats.usgs.gov/ss/). These geospatial datasets, along with basin characteristics datasets for Puerto Rico published as a separate USGS data release (https://doi.org/10.5066/P9HK9SSQ), were used to delineate watersheds and develop the peak-flow and low-flow regression equations used by StreamStats. The geospatial dataset described herein are the sink watershed grid rasters at a 10-m resolution. A value is assigned to pixels in each sink watershed and the count of cells that drain to that...

This data release contains daily time series estimates of natural streamflow at 5,439 GAGES-II non-reference streamgages in 19 study regions across the conterminous United States from October 1, 1980 through September 30, 2017, using five statistical techniques: nearest-neighbor drainage area ratio (NNDAR), map-correlation drainage area ratio (MCDAR), nearest-neighbor nonlinear spatial interpolation using flow duration curves (NNQPPQ), map-correlation nonlinear spatial interpolation using flow duration curves (MCQPPQ), and ordinary kriging of the logarithms of discharge per unit area (OKDAR). NNDAR, MCDAR, NNQPPQ, and MCQPPQ estimates were computed following methods described in Farmer and others (2014), with...
In this study, we develop urban ecosystem accounts in the U.S., using the System of Environmental-Economic Accounting Experimental Ecosystem Accounting (SEEA EEA) framework. Most ecosystem accounts focus on regional and national scales, which are appropriate for many ecosystem services. However, ecosystems provide substantial services in cities, improving quality of life and contributing to resiliency for substantial parts of the population. Our models estimate energy savings for indoor cooling resulting from heat mitigated by trees and rainfall intercepted by trees. Both models cover major cities in the contiguous U.S. and report the results through physical supply and use tables for multiple accounting periods...

This layer represents a crosswalk of the GAP/LANDFIRE National Terrestrial Ecosystems 2011 land cover to the Class level of the U. S. National Vegetation Classification (USNVC). At the Class level vegetation types are distinguished based on dominant growth form (for example - Forest & Woodland). In addition to the vegetation types in the map legend there are land use classes (for example - open water, agriculture) that are not a part of the USNVC. Visit these sites for more information about the National Classification, the Federal Geographic Data Committee- Vegetation Subcommittee and the USNVC Standard. These data cover the entire continental U.S. and are a continuous data layer. These raster data have a 30 m...

Water velocities and discharge were measured in the lock chamber and immediately downstream of Brandon Road Lock on the Des Plaines River at river mile 286 on December 9-10, 2014 using Teledyne RDI Rio Grande 600 and 1200 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with a differential GPS receiver with submeter accuracy. These ADCP measurements were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi River Interbasin Study (GLMRIS). Velocity measurements were processed using the Velocity Mapping Toolbox (Parsons and others, 2013) to derive temporally- and spatially-averaged water velocity values. Discharge measurements were processed with the QRev discharge...

Actual evapotranspiration (ETa) values estimated for specified areas including 1) total county areas; 2) potentially irrigated areas within each county; and 3) mapped extents of irrigated lands within each county provided by some states. These ETa estimates were provided to the USGS National Water Use Science Project by the USGS Earth Resources Observation and Science (EROS) Center (Gabriel Senay and MacKenzie Friedrichs, written communication, 2/20/2017) and are based on 1-square kilometer resolution 2015 Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data analyzed through the operational Simplified Surface Energy Balance (SSEBop) model using methods of Senay and others (2013).

The U.S. Geological Survey (USGS) collected hydroacoustic data of the St. Croix River adjacent to the Osceola (WI) boat ramp for hydrographic and benthic mapping prior to the reconstruction project implemented by the National Park Service (NPS). Backscatter is the acoustic reflectivity, which is the measure of energy obtained from the echo intensity, and can provide an indication about the nature of the river bottom and its physical character. Image analysis and classification of backscatter, with the combined datasets of bathymetry (and its derivatives) and ground truthing, can predict surficial substrate, or sediment type. For habitat analysis, these datasets were desired by the NPS to help inform and mitigate...
Hawai‘i’s endangered waterbirds have experienced epizootics caused by ingestion of prey that accumulated a botulinum neurotoxin produced by the anaerobic bacterium Clostridium botulinum (avian botulism; Type C). Waterbird carcasses, necrophagous flies, and their larvae initiate and spread avian botulism, a food-borne paralytic disease lethal to waterbirds. Each new carcass has potential to develop toxin-accumulating necrophagous vectors amplifying outbreaks and killing hundreds of endangered birds. Early carcass removal is an effective mitigation strategy for preventing avian intoxication, toxin concentration in necrophagous and secondary food webs, and reducing the magnitude of epizootics. However, rapid detection...
Prior research has shown that sediment budgets, and therefore stability, of microtidal marsh complexes scale with areal unvegetated to vegetated marsh ratios (UVVR) suggesting these metrics are broadly applicable indicators of microtidal marsh vulnerability. This effort has developed the UVVR metric using Landsat 8 satellite imagery for the coastal areas of the contiguous United States (CONUS). These datasets provide annual averages of 1) developed, 2) vegetated, 3) unvegetated fractional covers and 4) an unvegetated to vegetated ratio (UVVR) at 30-meter resolution over the coastal areas of the contiguous United States for the years 2014-2018. Additionally, multi-year average values of vegetated fractional cover...

The data document the results of several microbe bioassays performed by the USGS on Phragmites australis plants, including those performed on mature leaves, seedlings, and dead leaf tissues exploration of the literature to find accounts of microbes associated with Phragmites worldwide. For the bioassays, we prepared 162 pure cultures isolated from Phragmites plants in North America along the east coast, Florida, the Gulf of Mexico, and the Great Lakes area, 125 of which were from a previous study, and 38 represent new collections. The DNA sequences used to identify the 37 new collections are included. Microbes were isolated from plants collected from 2015-2018. We performed assays using both North American plant...

This dataset contains an inventory of South Carolina U.S. Geological Survey (USGS) streamgages evaluated in 2017 as part of gage network gap assessment. Both continuous record and crest stage gages are included in this dataset. The data are grouped into three categories: rural streamgages with equal to or greater than 10 years of peak-flow data, rural streamgages with less than 10 years of peak-flow data, and urban streamgages.
Water, bed sediment, and biota were sampled in selected streams from Butte to near Missoula, Montana, as part of a monitoring program in the upper Clark Fork Basin of western Montana. The sampling program was led by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency.

This dataset accompanies planned publication 'Determining fault geometry through the transport-parallel distribution of thermochronometer cooling ages'. The Ar/Ar data is for samples that record the thermal history of the area. The geochronology provides time constraints for the thermal histories studied in the manuscript. Samples were collected from Nepal, overseen by Nadine McQuarrie (University of Pittsburgh), who sent them to the USGS Denver Argon Geochronology Laboratory for Ar/Ar analysis.

We report the site number and locations of 5798 streamflow gages displaying zero flow for at least one day in their daily records. 4891 of these gages are from the GRDC network, and 906 are USGS gages in the contiguous US. Additionally, provisional data for two USGS gages 1) Rio Puerco near Bernardo, NM (USGS site: 08353000) and 2) Agua Fria River Near Mayer, AZ (USGS site: 09512500) are provided to illustrate zero flow record behaviors.
Observers at Hakalau Forest National Wildlife Refuge recorded the use by birds of koa (Acacia koa) and ohia (Metrosideros polymorpha) trees in two sites that were recovering from ungulate disturbance and two reforestation sites where trees had been planted. Observations were made pre- and post-defoliation of koa trees by koa moths (Scotorythra paludicola) during 2013. Focal trees at each site were selected haphazardly and observed for 2 minutes to determine the total number individual birds that visited the tree. Birds were counted when they were already present or as they flew into a tree during the 2-minute period, regardless of whether they departed before the end of the observation period. Birds were identified...
Bird banding at 2 locations adjacent to one another (one in koa restoration forest, and other in native intact forest) at Hakalau Forest National Wildlife Refuge before and after the start of an outbreak by koa moths (Scotorythra paludicola) during 2013. Each bird was measured with an electronic scale accurate to 1/10th g. Results indicate that insectivorous birds increased in mass, on average, while generalist diet species showed marginally significant increases, and two out of three nectarivorous and frugivorous birds did not have significant change.
