Data describing the pH of soil prior to and following establishment of a mixed species wading bird rookery Data describing the pH of soil prior to and following establishment of a mixed species wading bird rookery
During the 2020 breeding season, Double-crested Cormorants invaded the historic breeding colony of a mixed species wading bird rookery in the Chesapeake Bay, resulting in the destruction of suitable nesting habitat and subsequent relocation of the rookery the following breeding season. This new rookery was established at a site where soil pH was being measured for an unrelated study...
Data Examining the Effects of Fire Timing and Snow Depth on Plant Emergence Phenology Growth and Flowering in a Restored Tallgrass Prairie in Wisconsin from 2016–2023 Data Examining the Effects of Fire Timing and Snow Depth on Plant Emergence Phenology Growth and Flowering in a Restored Tallgrass Prairie in Wisconsin from 2016–2023
This dataset includes data from a study testing the interacting effects of disturbance regime and winter snow depth on plant emergence, growth, and reproductive effort in a restored tallgrass prairie. The “Treatments.csv” file includes details of the experimental design. The design includes two snow manipulation treatments (ambient or reduced snow) nested within one of three disturbance...
Data for an Erosion Potential and Flood Vulnerability Assessment of Streams and Stream Crossings at Acadia National Park, Maine Data for an Erosion Potential and Flood Vulnerability Assessment of Streams and Stream Crossings at Acadia National Park, Maine
The U.S. Geological Survey (USGS), in cooperation with the National Park Service (NPS), has compiled Geographic Information Systems (GIS) datasets to assess the erosion potential and flood vulnerability of streams and stream crossings within Acadia National Park, Maine. Erosion potential of streams is estimated using remotely measured geomorphic and hydrologic variables associated with...
Data for Analysis of Decadal Trends in the Quality of Groundwater Used for Public Drinking-Water Supply in California, 2004-2023, California GAMA Priority Basin Project Data for Analysis of Decadal Trends in the Quality of Groundwater Used for Public Drinking-Water Supply in California, 2004-2023, California GAMA Priority Basin Project
This data release documents datasets supporting analysis of decadal trends in the quality of groundwater resources used for public drinking-water supply across California. The analysis primarily utilizes samples collected by the U.S. Geological Survey's Groundwater Ambient Monitoring and Assessment Priority Basin Project (GAMA-PBP) during 2004-2023 as part of a cooperative research...
Data for decadal shifts in groundwater age detected by environmental tracers across California, USA Data for decadal shifts in groundwater age detected by environmental tracers across California, USA
This data release documents seven tables containing environmental tracer data and lumped parameter model results used to evaluate temporal changes in groundwater age at 268 sites across California from 2004 to 2021. These sites are spatially distributed throughout the state and represent groundwater at depths used for public supply. Each site was sampled at least twice, with paired...
Data for Development of a Risk Model of Domestic Dog Attacks on Threatened Agassiz’s Desert Tortoises (Gopherus agassizii) in the Mojave and Colorado Deserts of California Data for Development of a Risk Model of Domestic Dog Attacks on Threatened Agassiz’s Desert Tortoises (Gopherus agassizii) in the Mojave and Colorado Deserts of California
The single database, assembled retrospectively between 2004 and 2007, which includes the following information: site name, desert region, distance (km) to the nearest settlement from the tortoise, unique identification number for the tortoise, sex, wear or aging class of the carapace, size of the tortoise, evidence of trauma to the gular horn and to shell and limbs, year collected, and...
Data for Evaluating 1,2-Dibromo-3-Chloropropane (DBCP) Trends in California Groundwater Data for Evaluating 1,2-Dibromo-3-Chloropropane (DBCP) Trends in California Groundwater
This data release documents dibromochloropropane (DBCP) data and environmental tracer data used to evaluate long-term trends and the history of DBCP in recharge in California groundwater. DBCP data from the California State Water Resources Control Board’s Division of Drinking Water (SWRCB-DDW), the USGS Groundwater Ambient Monitoring and Assessment Priority Basin Project (USGS GAMA-PBP)...
Data for Factors affecting Benthic Macroinvertebrate Health in the City of Roanoke Virginia, 2020 – 2023 Data for Factors affecting Benthic Macroinvertebrate Health in the City of Roanoke Virginia, 2020 – 2023
The United States Geological Survey Virginia and West Virginia Water Science Center (USGS VA-WV-WSC) and City of Roanoke, Virginia assembled this data release to support a report that analyzed factors affecting benthic macroinvertebrate health in the City of Roanoke, Virgina between calendar years 2020 and 2023. The benthic macroinvertebrate and stream habitat sampling and surveying were...
Data for the Hydrologic and Water-Quality Characterization of Levittown Lake, Toa Baja, Puerto Rico, April 2010 – June 2011 Data for the Hydrologic and Water-Quality Characterization of Levittown Lake, Toa Baja, Puerto Rico, April 2010 – June 2011
This data release contains data for the hydrologic and water-quality characterization of Levittown Lake, from April 2010 to June 2021. Three child items were included in the data release to summarize the results of the (1) community productivity through the light and dark bottle method (2) two diel data collection efforts, and (3) spatial data associated with the bathymetric survey...
Data for Uranium-Lead Isotope Geochronology from Select Projects in Alaska Data for Uranium-Lead Isotope Geochronology from Select Projects in Alaska
This dataset consists of three tables containing sample information and uranium-lead (U-Pb) isotopic data and U-Pb ages measured in zircon collected from igneous rocks in Alaska. The samples were collected between 2019 and 2023 and analyzed by laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) by GeoSep Services. The dataset includes 412 analyses across 13 samples...
