Olivine and glass analyses for select eruptions of Kilauea Volcano, Hawai'i Olivine and glass analyses for select eruptions of Kilauea Volcano, Hawai'i
Olivine and glass major and minor element chemistry for select eruptions of Kilauea Volcano, Hawai'i as measured by electron microprobe, with secondary standard analyses.
Online survey responses from users of the Joint Fire Science Program Fire Science Exchange Network from February 2021 Online survey responses from users of the Joint Fire Science Program Fire Science Exchange Network from February 2021
The USGS, on behalf of the Joint Fire Science Program (JFSP), conducted an evaluation of the Fire Science Exchange Network (FSEN), which connects wildland fire scientists and practitioners through 15 individual exchanges across the United States to help address complex wildfire needs and challenges. This data set is from an online survey sent to more than 16,000 exchange network users...
Optimization simulations to estimate maximum brine injection rates in the Illinois Basin Optimization simulations to estimate maximum brine injection rates in the Illinois Basin
We developed a methodology to estimate maximum brine injection rates in subsurface formations across wide geographic areas using inverse modeling-based optimization techniques. We first defined geographic areas where groundwater was too saline to meet the standard for drinking water and where sufficient confining units existed above and below the injection layers. We then assumed...
Oregon spotted frog (Rana pretiosa) observations in Oregon (ver. 6.0, March 2025) Oregon spotted frog (Rana pretiosa) observations in Oregon (ver. 6.0, March 2025)
This dataset contains information from surveys conducted 2016-2024 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in Oregon. USGS research activities 2016-2024 were divided into seven study design categories: breeding (egg mass counts), mid-level (visual encounter surveys for occupancy monitoring), apex (mark-recapture), telemetry, trapping, water...
Oregon spotted frog (Rana pretiosa) telemetry and habitat use at Crane Prairie Reservoir in Oregon, USA Oregon spotted frog (Rana pretiosa) telemetry and habitat use at Crane Prairie Reservoir in Oregon, USA
We used radio-telemetry to study late-season movement and habitat use by Oregon spotted frogs (Rana pretiosa) at Crane Prairie Reservoir in Oregon. This dataset includes individual frog location data and habitat use during each tracking event that occurred roughly weekly between September and late November of 2018.
Organic and inorganic constituents in surface water and native and non-native fish and frog health data collected from streams, impoundments and wetlands in the New Jersey Pinelands, 2017-2020 (ver. 1.1, August 2022) Organic and inorganic constituents in surface water and native and non-native fish and frog health data collected from streams, impoundments and wetlands in the New Jersey Pinelands, 2017-2020 (ver. 1.1, August 2022)
The data presented include concentrations of 122 organic, 23 inorganic constituents, and estrogenicity in water collected from 13 off-stream non-point source sites (natural and created wetlands) and eight on-stream point source sites (streams and impoundments) in the New Jersey Pinelands, 2017-2020. Native and non-native fish health data collected from the on-stream sites as well as...
Organic and Metal Contaminants in Fish Tissue Collected from the Niagara River Area of Concern, New York, 2018 Organic and Metal Contaminants in Fish Tissue Collected from the Niagara River Area of Concern, New York, 2018
Fish tissue from 203 samples collected at five locations in the Niagara River Area of Concern in 2018 were analyzed for a wide range of analytes including Polychlorinated Biphenyls (PCBs), pesticides (E1 and E2), polycyclic aromatic hydrocarbons (PAH), organochlorine and other persistent organic compounds, metals, lipid and moisture. Over 230 analytes were analyzed in the tissue samples...
Organic petrology of Cretaceous Mowry and Niobrara source-rock reservoirs, Powder River Basin, Wyoming, USA Organic petrology of Cretaceous Mowry and Niobrara source-rock reservoirs, Powder River Basin, Wyoming, USA
Imaging of Niobrara Formation and Mowry Shale samples from a range of thermal maturities provided observations and data on pore systems, organic matter (OM) types and associations with mineralogy and fabric, wettability, and microporosity associated with both diagenetic and detrital clays. Imaging techniques included scanning electron microscopy, organic petrography and correlative...
Overlapping seabed images and location data acquired using the SQUID-5 system at Eastern Dry Rocks coral reef, Florida, in May 2021, with derived point cloud, digital elevation model and orthomosaic of submerged topography Overlapping seabed images and location data acquired using the SQUID-5 system at Eastern Dry Rocks coral reef, Florida, in May 2021, with derived point cloud, digital elevation model and orthomosaic of submerged topography
Underwater images were collected using a towed-surface vehicle with multiple downward-looking underwater cameras developed by the U.S. Geological Survey (USGS). The system is named the Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). The raw images and associated navigation data were collected at Eastern Dry Rocks, a coral reef located...

Oyster Bayou Marsh Creation and Terracing (CS-59): 2018 land-water classification Oyster Bayou Marsh Creation and Terracing (CS-59): 2018 land-water classification
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
Pacific Walrus Coastal Haulout Occurrences Interpreted from Satellite Imagery Pacific Walrus Coastal Haulout Occurrences Interpreted from Satellite Imagery
