Map data from landslides triggered by Hurricane Maria in two study areas in the Las Marías Municipality, Puerto Rico
In late September 2017, intense precipitation associated with Hurricane Maria caused extensive landsliding across Puerto Rico. Much of the Las Marías municipality in central-western Puerto Rico was severely impacted by landslides. Landslide density in this region was mapped as greater than 25 landslides/km² (Bessette-Kirton et al., 2019). In order to better understand the controlling variables of
Inventory of water bottling facilities in the United States, 2023, and select water-use data, 1955-2022
An inventory of facilities that bottle water or other beverages containing water (including soft drinks, beer, wine, or spirits) or that manufacture ice was compiled by combining available datasets from multiple sources. This water bottling inventory dataset includes facilities within all 50 states of the United States, one federal district (Washington, District of Columbia), and three territories
Data release for fault activity in the San Gabriel Mountains, USA: insights from landscape morphometrics, erosion rates, and fault-slip rates (ver. 2.0, November 2023)
This report summarizes geomorphic data and analysis from the range front and interior of the San Gabriel Mountains, California, USA. For catchment-average erosion rates, we describe the methodology used to collect samples of detrital sediment, determine concentrations of cosmogenic beryllium-10 in purified quartz isolated from the samples, and use those nuclide concentrations to calculate erosion
Bedrock geologic map database for the Durango 1-degree x 2-degree quadrangle, southern Colorado: Contributions to the National Geologic Map (ver. 2.0, June 2024)
This data release presents geologic map data for the bedrock geology of the Durango 1-degree by 2-degree quadrangle. Geologic mapping incorporates new interpretive contributions and compilation from published geologic map data sources primarily ranging from 1:24,000 to 1:50,000 scale. Much of the geology incorporated from published geologic maps is adjusted based on digital elevation model and nat
Pharmaceutical Data from the California Groundwater Ambient Monitoring and Assessment Priority Basin Project (GAMA-PBP) Domestic Well Groundwater Quality Studies, 2014 - 2021
The U.S. Geological Survey collected groundwater samples from 537 domestic wells for pharmaceutical compounds between 2014 and 2021 from 9 different study units. These wells were sampled as part of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domes
Application of the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System (NHM-PRMS),1980-2016, Daymet Version 3 calibration
This data release contains inputs and outputs for hydrologic simulations of the conterminous United States (CONUS) using the National Hydrologic Model (NHM) application of the Precipitation Runoff Modeling System (PRMS) in ASCII and binary format and explanatory graphics in pdf format. These simulations were developed to provide estimates of water availability for historical conditions for the per
MODFLOW-NWT Upgrade and Preliminary-Assessment of a Groundwater-Flow Model of the Seacoast Bedrock Aquifer, New Hampshire
Improvements to an existing regional groundwater-flow model of a 160-square mile area of coastal New Hampshire (https://doi.org/10.3133/sir20085222), incorporating MODFLOW-NWT and by more accurately representing stream characteristics, were presented at the MODFLOW and More 2017 conference in an example simulating approximate changes in water use. The groundwater-flow model developed for the previ
Digital elevation model of the lava dome in the crater of Mount St. Helens, November 12, 1986
The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is the May 18th eruption marked the beginning of a period of eruptive activity that lasted through 1986. From October 1980 through October 1986, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater floor. Most o
Flow, turbulence, and bathymetric measurements of the Missouri River at Searcys Bend, near Huntsdale, Missouri September 16, 2021
This dataset includes measurements of flow, turbulence, and bathymetry generated from multibeam bathymetry for a short reach of the Missouri River at Searcys Bend (SB) near Huntsdale, Missouri. Flow and turbulence were characterized using a Signature 1000 mounted on an anchored moving boat and an Aquadopp mounted on a tripod near the bed. Repeat bathymetric measurements were made in small patches
Crayfish morphometric measurements, burrow attributes and occupancy in response to physical burrow barriers
Data were collected in association with the application of two physical barrier treatments, bentonite clay (a sealing agent) and expanding foam (an insulation sealant), in natural pond-burrows to suppress or kill the invasive red swamp crayfish (Procambarus clarkii). Data include burrow diameter and depth, crayfish sex and size, and determination of the treatment reaching the burrow chamber.
Data on the acute and chronic toxicity of sodium chloride and sodium sulfate to freshwater organisms in a low hardness water representing Louisiana water conditions
We determined acute and chronic toxicity of sodium chloride (NaCl) and sodium sulfate (Na2SO4) to up to 7 freshwater species of different taxa in a hardness water of 40 mg/L as CaCO3 and evaluated the effect of 4 hardness waters (15, 30, 60, and 120 mg/L as CaCO3) on acute toxicity of NaCl and Na2SO4 to 3 sensitive species tested in the acute exposures. This data release reports results from acute
Slide-hold-slide experiments on Westerly Granite at temperatures up to 250 °C
Laboratory slide-hold-slide tests were conducted in a conventional triaxial deformation configuration on 1-inch diameter cylindrical cores of Westerly granite bisected by a sawcut oriented at 30 degrees from vertical. Tests were conducted at a constant confining pressure of 30 MPa with a 10 MPa pore fluid pressure. The pore fluid was deionized water. Experiments were conducted at temperatures of 2
