The Pacific Northwest is home to numerous faults that cut through the surrounding crust including the Seattle fault. Over time, frictional stresses accumulate along these faults, building slowly until they exceed the fault's strength, resulting in an earthquake. Evidence of these earthquakes may be found in Pacific Northwest lakes. Past underwater landslides caused by the earthquakes...

This carbon dataset is generated from the parallel Integrated Biosphere Simulator (pIBIS). Annual carbon variables cover 1985-2020 at 1-km (990m) spatial resolution. All the variables are in NetCDF format. Each variable has 36 layers, 2960 rows, 4677 columns, and in WGS_1984_Albers projection. A single layer mask file TIF is provided. Carbon stock and flux units are in kgC/m2 and kgC/m2...

This dataset includes downwelling irradiance data collected at night on the water's surface and daytime attenuation through the water column. Spectrally specific irradiance values were collected with a Biospherical Instruments Compact-Optical Profiling System (C-OPS) device to measure artificial light at night (ALAN) in Lake Washington, WA. This dataset consists of ALAN surface...

We conducted a study to assess the timing of outmigration and survival of juvenile Chinook salmon in relation to managed water flows in the Klamath River. Juvenile salmon were implanted with acoustic telemetry transmitters, and their movements were tracked using remote receivers deployed throughout the lower Klamath River, from Iron Gate Dam to the river’s mouth. Because transmitter...

Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated...

This U.S. Geological Survey (USGS) data release contains results of a paleolimnological analysis of cyanobacteria occurrence in Moreau and Brant Lake in the Adirondack Region of New York based on a single sediment core collected in each lake in September, 2022. The data types include 1) lake sediment core data for lead-210 age dating, 2) akinete classification and enumeration data, 3)...

The U.S. Geological Survey, in partnership with the National Park Service's Colonial National Historic Park (COLO), used commercially available satellite data and soil samples from around Jamestown Island to evaluate vegetative health and soil conditions on the island to further understand the extent and severity of conditions that threaten archaeological sites and vegetation. 50 sites...

Potentiometric-surface and depth-to-water maps for spring 2022 were created for the Mississippi River Valley alluvial aquifer (MRVA) using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. The potentiometric surface was referenced to the North American Vertical Datum of 1988 (NAVD 88), This data release contains (1) the location...

The Geysers geothermal field in northern California is currently the largest energy producing steam field in the world. To better understand temporal subsurface changes in the steam field a geophysical monitoring project including continuous passive seimsic and repeat magnetotelluric measurements was funded by the California Energy Commission and led by Lawrence Berkeley National Lab. As...

Geochemical data included were generated as part of the Critical Minerals Mapping Initiative (CMMI). Individual samples are classified according to the Hofstra et al. (2021) CMMI deposit classification scheme. The goal of CMMI is to collaborate with Geoscience Australia and the Geological Survey of Canada to build a global database of critical minerals in a variety of ore deposits. The...

This dataset includes rock magnetic susceptibility and gamma ray spectrometry measurements from 204 outcrops in southwest Montana during 2025. The measurements were collected to understand the causative sources of airborne magnetic and radiometric survey anomalies in the Idaho-Montana porphyry belt. Sixteen magnetic susceptibility measurements were collected at each analyzed site using a...

Analyses were conducted in 2025 to examine glaciolacustrine rhythmic laminations interpreted as annual layers (varves) in a sediment core collected from Great Swamp National Wildlife Refuge in Morris County, New Jersey in 2010. The dataset includes results from portable X-ray fluorescence (pXRF), particle size analysis (PSA), visible (color) and near-infrared spectrophotometry, and...
