This child item dataset contains horizontal-to-vertical spectral ratio (HVSR) data from Broome County, New York, for 15 measurements, CNHVSR2 through CNHVSR10. Raw and processed HVSR data for each HVSR measurement are included in zipped directories named by the measurement site identifier. Site identifiers are designated by a county sequential numbering system (CNHVSR2, CNHVSR3, etc. where "CN" indicates Chenango County).
Alluvial basin boundaries in the Upper Rio Grande Basin (URGB) were a needed dataset for the groundwater component of the URGB Focus Area Study (FAS). A literature and data search revealed not all of the alluvial fill basins existed in a digital format that could be imported and used in a Geographic Information System (GIS). Available resources such as georeferenced report figures, digital elevation models (DEMs), principal aquifer dataset, surficial geology, and structural features, such as faults, were used to aid in defining the alluvial basin boundaries. An Esri ArcGIS geodatabase was created to house the final digitized dataset of the following alluvial basins: San Luis, Espanola, Socorro, La Jencia, San Marcial,...

Depth-to-water data in the San Joaquin Valley, CA were collected in 1910 and published in Mendenhall and others, 1916. These data were used to create a depth-to-water contour of the Valley described in Plate 1 entitled "Map of San Joaquin Valley, California showing artesian areas, ground-water levels and location of pumping plants", which includes a depiction of geographical areas where flowing well (artesian) conditions existed in 1910. These "Areas of flowing wells" have been converted into a digital vector format (ArcGIS Shapefile) for use in future research.

From July to November 2019, 48 environmental samples and four quality assurance and quality control samples were collected throughout the Lake Champlain and Susquehanna River Basins. Samples were collected from 10 production wells and nine domestic wells in the Lake Champlain Basin, and 14 production wells and 15 domestic wells in the Susquehanna River Basin. Of the total wells sampled, 24 were completed in bedrock and 23 were completed in sand and gravel. Approximately 20 percent of samples were collected from wells that previously have been sampled as part of this study in 2005, 2009, and 2014. Groundwater samples were collected prior to any treatment or filtration systems, from existing domestic and production...

An extreme gradient boosting (XGB) machine learning model was developed to predict the distribution of nitrate in shallow groundwater across the conterminous United States (CONUS). Nitrate was predicted at a 1-square-kilometer (km) resolution at a depth below the water table of 10 m. The model builds off a previous XGB machine learning model developed to predict nitrate at domestic and public supply groundwater zones (Ransom and others, 2022) by incorporating additional monitoring well samples and modifying and adding predictor variables. The shallow zone model included variables representing well characteristics, hydrologic conditions, soil type, geology, climate, oxidation/reduction, and nitrogen inputs. Predictor...
A potentiometric surface map for spring 2016 was created for the Mississippi River Valley alluvial (MRVA) aquifer, which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. Most of the wells were measured annually or one time, after installation, but some wells were measured more than one time in a year and a small number of wells were measured continually. Streamgages were typically operated continuously. The potentiometric surface map for 2016 was created as part of the U.S. Geological Survey (USGS) Water Availability and Use Science Program to support investigations that characterize...

The Mississippi Alluvial Plain (MAP) is one of the most important agricultural regions in the United States and underlies about 32,000 square miles of Missouri, Kentucky, Tennessee, Mississippi, Louisiana, and Arkansas. The MAP region supports a multibillion-dollar agricultural industry. The MAP is part of the Mississippi Embayment with several water-bearing units that make up the Mississippi Embayment Regional Aquifer System (MERAS). These water bearing units include the Mississippi River Valley Alluvial aquifer, Claiborne aquifers and Wilcox aquifers. Two areas in northeastern Arkansas, the Cache and Grand Prairie areas have been designated as critical groundwater areas because of decades of groundwater declines...

Funded by Arizona Game & Fish Department, our team of conservation biologists and GIS Analysts at Northern Arizona University are creating detailed linkage designs for 16 priority areas highlighted in the Wildlife Linkages Assesment. These plans identify and map multi-species corridors that will best maintain wildlife movement between wildland blocks, as well as highlight specific planning and road mitigation measures required to maintain connectivity in these corridors. Note: The linkage design reports are in compressed PDF format for faster download. Unfortunately, the compression occasionally makes small text on maps within the report difficult to read. If you would like a high-resolution PDF or PNG copy of any...

We combine climate and soil properties with a mechanistic soil water model to explain temporal fluctuations in perennial grass cover, quantify where and the degree to which incorporating soil water dynamics enhances our ability to understand temporal patterns, and explore the potential consequences of climate change by assessing future trajectories of important climate and soil water variables. Our analyses focused on long-term (20 to 56 years) perennial grass dynamics across the Colorado Plateau, Sonoran, and Chihuahuan Desert regions. We found that climate variability has negative effects on grass cover, and that precipitation subsidies that extend growing seasons are beneficial. Projections of water balance variables...
