Inventory of rainfall-induced landslides in Puerto Rico, 2022-2023 Inventory of rainfall-induced landslides in Puerto Rico, 2022-2023
This data release provides a point inventory of rainfall-induced landslides in Puerto Rico during 2022 and 2023. Each record includes the date, latitude, longitude, descriptive location, spatial confidence, reporting source, and reference link. Landslides were identified from public reports, municipal sources, and National Weather Service call logs. Verification required dated...
Seafloor Elevation and Volume Change along the Upper Florida Keys Reef Tract: 1934 to 2002 and 2002 to 2016 Seafloor Elevation and Volume Change along the Upper Florida Keys Reef Tract: 1934 to 2002 and 2002 to 2016
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted research to quantify bathymetric changes in the Northern Florida Keys from Triumph Reef to Pickles Reef during two time periods, 1934 to 2002 and 2002 to 2016, within a 234.2 square-kilometer area. USGS staff calculated changes in seafloor elevation for both time periods using historical
Cesium-137 Isotope Activity Measured in Core 22KAR_21A from Karluk Lake, Kodiak Island, Alaska in 2022 Cesium-137 Isotope Activity Measured in Core 22KAR_21A from Karluk Lake, Kodiak Island, Alaska in 2022
The dataset lists specific activities of Cesium-137 in disintegrations per minute per gram (dpm per g) from 21 samples in the upper 33 centimeters of sediment core 22KAR-21A collected in Karluk Lake, Kodiak Island, Alaska.
Storm-Induced Coastal Change Forecasts: Louisiana Hurricanes Laura and Delta 2020 Storm-Induced Coastal Change Forecasts: Louisiana Hurricanes Laura and Delta 2020
These datasets contain information on the probabilities of storm-induced erosion (collision, overwash and inundation) on sandy beaches along the U.S. Gulf coast of Texas, Louisiana, Mississippi, and Alabama during hurricane impact conditions of Hurricanes Laura and Delta in 2020. The analysis is based on a storm-impact scaling model that uses observations of dune morphology combined with
Data acquired in laboratory experiments conducted to characterize Ag bioaccumulation kinetics in Daphnia magna after exposures to polystyrene microplastics and Ag nanoparticles Data acquired in laboratory experiments conducted to characterize Ag bioaccumulation kinetics in Daphnia magna after exposures to polystyrene microplastics and Ag nanoparticles
Microplastics (MPs) are an environmental concern. They can interact with other contaminants and pose new threats to organisms. We assessed the effect MPs on silver (Ag) bioaccumulation in the filter-feeding zooplankton Daphnia magna exposed to Ag nanoparticles at environmentally relevant concentrations.
Concentration results for per- and polyfluoroalkyl substances (PFAS) analyzed in fish tissue, bed sediment, and biofilm samples, Montana, 2023 Concentration results for per- and polyfluoroalkyl substances (PFAS) analyzed in fish tissue, bed sediment, and biofilm samples, Montana, 2023
This data release contains the concentration results of per- and polyfluoroalkyl substances (PFAS) collected in fish tissue and whole blood, bed sediment and biofilm samples from water bodies in and surrounding the Little Bighorn River (LBHR) in Montana in July 2023. A total of 29 filets and whole blood samples were collected from 10 brown trout, 10 catfish, 6 rock bass, and 3 goldeye...
