A Catalog of Low-Frequency Earthquakes at the Southern Edge of Cascadia Subduction David R. Shelly1 1 U.S. Geological Survey, Geological Hazards Science Center, Golden, CO 80401 This catalog contains 61,441 detections from 27 low-frequency earthquake (LFE) families located in an isolated zone offset to the west from the southern edge of the main band of Cascadia tremor. The included...

This dataset includes measurements of physical and biological parameters of two restored tidal wetlands that utilized beneficial reuse material (Hamilton Restoration, Sonoma Baylands), and compares their attributes to two wetlands that have been restored through natural tidal sediment accretion (Tolay, Carl’s Marsh) and one wetland that had never been diked (Pinkston Slough). Throughout...

Cobalt, designated a critical mineral by the European Union and the United States, is a crucial component of the lithium-ion batteries found in cell phones, electric vehicles, and personal computing devices. Over half of the world’s cobalt supply is produced in the Democratic Republic of the Congo (DRC), where cobalt is mined in both large-scale and artisanal or small-scale operations...

Porphyry copper deposits are the world's primary source of copper and can also host a variety of secondary commodities identified as critical by the U.S. Geological Survey (U.S. Geological Survey, 2022). These deposits occur primarily along convergent plate margins, and their metal association and geochemical characteristics are reflective of whether the deposit formed in continental...

This dataset includes field measurements of biological nitrogen fixation (BNF) in all major N-fixing niches across natural terrestrial biomes globally. The dataset comprises 32 variables including site location, biome type, N-fixing niche, sampling year, quantification method, BNF rate (in kg N/ha/y), the percentage of nitrogen derived from the atmosphere, N-fixer or N-fixing substrate...

Microscopic images of hematologically stained whole blood cells from diploid and triploid Grass Carp (Ctenopharynngodon idella) were obtained by a laboratory microscope and field microscope.

A method was developed to measure the presence and concentration of the organic volatile fatty acids (VFA) formate, malate, lactate, acetate, and propionate in aqueous samples using high performance liquid chromatography (HPLC) and ultraviolet absorbance detection. This dataset includes a method detection limit (MDL) study, along with appropriate quality control samples, used to verify...

Revised dataset of landslides triggered by the 2011 M9.1 Tohoku earthquake. Point data are presented as a csv with new failure types, source type, and impacts to the build environment classification for mapped landslides. This dataset is an extension of the Wartman et al. (2013) landslide inventory following the Tohoku earthquake, and includes the original landslide IDs and type...

This dataset details individual species and natural habitat vulnerability rankings, including contextual study-specific information. This data was collected from original publications found through a literature search. Information is cumulative to include climate change vulnerability assessment (CCVA) results summarized in Staudinger et al. (2015) and published as of December 2023.

The United States Geological Survey (USGS) collected a total of 179 samples of surficial sediment from abandoned mine wastepiles, ephemeral channels below wastepiles, nearby outcrops, and background areas representative of the undisturbed lithology within the Henry Mountains and Fremont mining districts (Krahulec, 2018). The samples are associated with the following mining claims within...

Broad-area, high-resolution, boat-based water quality mapping surveys of the Sacramento-San Joaquin Delta (Delta) were conducted in June and September of 2024. Each survey was comprised of one day of high-resolution mapping. The regions covered included Discovery Bay and Old and Middle Rivers in the South Delta Tidal Transition Zone. On each day, the route of the mapping survey was...

Field data for fishes sampled using bottom and surface gill nets during daylight hours on October 22-24, 2024 in Lower Blue Lake, Lake county, California, USA. This data release includes the results of all measured environmental parameters and fish taxa included in the analysis.
