Oceanographic Time Series Measurements Collected at Madeira Beach, Florida Oceanographic Time Series Measurements Collected at Madeira Beach, Florida
The U.S. Geological Survey (USGS) deployed a series of oceanographic instruments at Madeira Beach, Florida configured to measure water levels, temperature, waves, and three-dimensional flow velocities throughout the water column. The instruments include (1) Spotter wave buoys with Smart Mooring (2) RBR pressure loggers, and (3) RDI Sentinel-V Acoustic Doppler Current Profilers (ADCP)...
Ocular field estimates of exotic annual and perennial grass cover across the Soda Wildfire Ocular field estimates of exotic annual and perennial grass cover across the Soda Wildfire
Data includes functional group cover of exotic annual grasses and deep rooted perennial grasses within the first five years after the 2015 Soda wildfire across different post-fire restoration treatments. Additional landscape and restoration treatment covariates hypothesized to influence post-fire invasive annual grass and perennial grass cover are included.
Olivine core and rim electron microprobe analyses for the January-March 2023 Halema‘uma‘u eruption of Kīlauea Olivine core and rim electron microprobe analyses for the January-March 2023 Halema‘uma‘u eruption of Kīlauea
The January-March 2023 Halema‘uma‘u eruption occurred within Kaluapele (Kīlauea’s summit caldera) beginning on January 5 and ending on March 7 (Mulliken et al. 2024). This eruption reoccupied a previously active vent in the western side of the lava lake, as well as opening additional new vents on the eastern side of the lake.

Olivine core and rim electron microprobe analyses for the June 2023 Halema‘uma‘u eruption of Kīlauea, Island of Hawai‘i Olivine core and rim electron microprobe analyses for the June 2023 Halema‘uma‘u eruption of Kīlauea, Island of Hawai‘i
The June 2023 Halema‘uma‘u eruption began on June 7 and ended on June 19 (~2 weeks; Mulliken et al. 2024). Field crews from the U.S. Geological Survey’s Hawaiian Volcano Observatory collected frothy pumice clasts from initial high fountaining on 7 June 2023 from accessible regions southwest of Kaluapele (Kīlauea’s summit caldera). Samples were collected from within a publicly closed area...
Olivine core and rim electron microprobe analyses for the September 2023 Halema‘uma‘u eruption of Kīlauea, Island of Hawai‘i Olivine core and rim electron microprobe analyses for the September 2023 Halema‘uma‘u eruption of Kīlauea, Island of Hawai‘i
The September 2023 Halema‘uma‘u eruption began on September 10 and ended on September 16 (~1 week; Mulliken et al. 2024). Field crews from the U.S. Geological Survey’s Hawaiian Volcano Observatory collected tephra samples from fissures that had opened up on an area of the caldera floor east of Halema‘uma‘u crater (see Lynn et al. 2024 for map). Air quenched spatter and tephra samples...
One- and two-dimensional hydraulic models for the Siletz River, Oregon One- and two-dimensional hydraulic models for the Siletz River, Oregon
Hydraulic models of the Siletz River, Oregon, were developed using the U.S. Army Corps of Engineers Hydraulic Engineering Center River Analysis System (HEC-RAS; version 6.5). A one-dimensional (1D) steady-flow model was developed from Moonshine Park to the City of Siletz, Oregon (river kilometer [Rkm] 87.2 to 68.5). Results from the 1D model provided insights into longitudinal patterns...
One-dimensional hydraulic and environmental DNA transport models for the Wallens Bend reach of the Clinch River, near Kyles Ford, Tennessee One-dimensional hydraulic and environmental DNA transport models for the Wallens Bend reach of the Clinch River, near Kyles Ford, Tennessee
This dataset includes the one-dimensional HEC-RAS model calibration files and simulation input and output files for the Wallens Bend (WB) reach on the Clinch River near Kyles Ford, Tennessee. Simulation results were used as input for environmental DNA transport models.
Ordinal-occurrence states of American pikas in the northern Sierra Nevada and southern Cascade Range from surveys during 2014-2019 Ordinal-occurrence states of American pikas in the northern Sierra Nevada and southern Cascade Range from surveys during 2014-2019
USGS researchers and technicians comprehensively surveyed each of 150 talus patches for evidence of American pika (Ochotona princeps) occurrence. Occurrence status at each patch was classified as either no pika evidence whatsoever, former pika occurrence, or current pika occurrence. Dataset also includes latitude and longitude, as well as mean elevation of the patch and the surveyor...
Organic Contaminants at Trespass Cannabis Grows on Federal Land in California, USA Organic Contaminants at Trespass Cannabis Grows on Federal Land in California, USA
Despite the legalization of recreational cannabis in California, illegal cultivation persists, particularly on public lands (trespass grows). These operations often divert water unlawfully and apply unauthorized chemical fertilizers and pesticides. This dataset reports the presence, and in some cases concentrations, of persistent chemicals in soil, water, and sediment in nearby streams...
Organic Geochemical Analysis Results Derived from Sediment Core Data Collected in 2021 from Siskiwit Bay, Lake Superior, Wisconsin, USA Organic Geochemical Analysis Results Derived from Sediment Core Data Collected in 2021 from Siskiwit Bay, Lake Superior, Wisconsin, USA
This dataset contains geochemical, isotopic, and biomarker data derived from sediment cores collected in Siskiwit Bay, Lake Superior, Wisconsin, USA. The dataset supports the reconstruction of historical phytoplankton communities, including cyanobacterial blooms, and environmental conditions over the past ~5,400 years. Measurements include carotenoid and chlorophyll pigments (via high...
Orthoimagery, digital surface model, and point cloud for the Big Bend restoration site, West Jordan Utah, January, 2022 Orthoimagery, digital surface model, and point cloud for the Big Bend restoration site, West Jordan Utah, January, 2022
The products presented here document conditions at the Big Bend restoration site on the Jordan River, West Jordan, Utah in January, 2022. Multiband imagery was collected shortly after the initiation of restoration actions. Images were collected using a 3DR Solo unoccupied aerial system (UAS) at a height approximately 400 feet above the surface of the Jordan River flood plain using a...
Orthomosaic maps of the Clackamas River, Oregon, produced from images acquired April 16-18, 2024 Orthomosaic maps of the Clackamas River, Oregon, produced from images acquired April 16-18, 2024
A Cessna 182 fixed-wing aircraft equipped with a multispectral camera was used to collect aerial imagery of selected river reaches within the Willamette River Integrated Water Science basin in Oregon. On April 16-18, 2024, image acquisition was focused on four reaches of the Clackamas River. Photogrammetry techniques were applied to the images consisting of visible or red, green, and...
