The Katahdin Woods and Waters (KAWW) National Monument TFG Unit Vegetation Mapping Project was initiated in the fall of 2022 by a grant through the USGS Natural Resource Preservation Program (NRPP) to classify and map vegetation types of the TFG Unit, thereby providing resource managers and biological researchers with useful baseline vegetation information. These data provide the...

This data release presents computed tomography (CT) imagery generated from coral core samples curated within the U.S. Geological Survey (USGS) Coral-Core Archive. These data were collected as part of ongoing USGS coral-reef research activities and include samples originating from multiple locations and collection efforts. A Geotek Rotating X-ray CT (RXCT) system was used to acquire x-ray...

The area burned in high severity fire as well as the proportion of fires burning at high severity have been increasing in southwestern ponderosa pine (Pinus ponderosa) forests since the 1980s, with over 100,000 hectares burning in many recent years and many fires burning at over 40% moderate to high severity. These fires often contain large patches (>100 ha) of 100% tree mortality. This...

This U.S. Geological Survey (USGS) Data Release contains chemical analysis information on sediment core and oil samples collected at the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA. Following a crude-oil spill in 1979, biodegradation of petroleum hydrocarbons in the contaminated aquifer has formed distinct zones of pH and/or redox...

We estimated thermal preference, acclimated chronic exposure, metabolic thermal optima, and critical thermal maximum for four species in the Notropis genus during 2022-2024. Thermal preference was estimated for Blacknose Shiner (Notropis heterolepis) and Ozark Shiner (N. ozarcanus) for individuals acclimated at both 22°C and 26°C for a minimum of two weeks using a behavioral shuttlebox...

As part of Upper Mississippi River Restoration (UMRR) Program, the U.S. Army Corps of Engineers (USACE) is conducting a study to understand what environmental factors are contributing to the failure of floodplain forests to regenerate. Broken Forest Canopy Identified by Lidar data sets: As part of Upper Mississippi River Restoration (UMRR), the U.S. Army Corps of Engineers (USACE) is...

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...

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

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.

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

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.

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...
