Data

This dataset is the result of coordinated efforts to compile data associated with stocking events for whitefishes and ciscoes (members of the Coregoninae subfamily) of Great Lakes origin. The dataset includes more than 4,700 records associated with coregonine stocking, from over 150 information sources, spanning the years 1870 - 2022. The compiled information includes species, quantities...

This dataset contains U-Pb isotopic data and ages plus trace element concentrations from titanite and apatite in igneous rocks collected for USGS projects in the Alaska Range, Yukon Tanana uplands of eastern Alaska, and a study of ophiolites in Alaska. A subset of analyses also includes simultaneous measurements of Sm-Nd isotope ratios. For this subset, split-stream configuration...

The Goat Rocks volcanic complex is a major andesitic locus in the southern Washington Cascade Range that persisted for approximately 3 million years (3.1 Ma to 115 ka) while coeval mafic volcanoes erupted on its periphery (Wall et al., 2018; Wall, 2022). The datasets presented in this data release were collected for a study that focuses on the mantle origin of the mafic magmas and their...

Phosphorus, nitrogen, chloride, and suspended-sediment loads, in 24 U.S. tributaries of the Great Lakes, were estimated using U.S. Geological Survey (USGS) data from the Great Lakes Restoration Initiative (GLRI) monitoring program for the period Oct 2010 through Sept 2023 (USGS water years 2011-23). Specific water-quality constituents include total phosphorus, orthophosphate, particulate...

This pilot study was intended to test whether Globorotalia truncatulinoides (G. truncatulinoides) and Globorotalia menardii (G. menardii) specimens could be successfully harvested from offshore plankton tow samples and kept alive in a laboratory at the U.S Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC). The methodologies and resources which were used to...

This dataset contains shoreline positions derived from available satellite imagery for multiple locations (Barter Island, Alaska; Elwha, Washington; Cape Cod, Massachusetts; Madeira Beach, Florida; and Rincon, Puerto Rico) across the United States for the time period 1984 to 2023, to support ongoing remote-sensing development and validation efforts.

We conducted ground-based surveys at 589 randomly selected 16-ha plots on the Yukon-Kuskokwim Delta, Alaska during 2015-2016. The plots were selected using a stratified random sampling plan in an area of 35,769 square km divided into 8 physiographic strata. The population totals from the stratified random design estimators were adjusted using detection ratios derived with a double...

Lake sturgeon (Acipenser fulvescens) have experienced large population declines due to overfishing, habitat degradation, and pollution. Due to these factors, lake sturgeon were extirpated in the Maumee River watershed (Ohio, USA). In 2018, a 20-year reintroduction program began that aims to establish a self-sustaining population in the Maumee River. To understand the potential success of...

Data for Figure 2 of U.S. Geological Survey Open-File Report 2021-1045 titled "Methodology and Technical Input for the 2021 Review and Revision of the U.S. Critical Minerals List." The data include the disruption potential, economic vulnerability, trade exposure, and overall supply risk for various mineral commodities in 2018. For some commodities, indicator scores are rounded to avoid...

These data are laboratory reflectance measurements conducted on a suite of altered mafic and ultramafic rocks. Visible-Near InfraRed (VNIR) and Short-Wave InfraRed (SWIR) reflectance measurements were made (~0.4 – 2.5 microns) using an artificial light source connected to an Analytical Spectral Devices (ASD) spectrometer. Spectra from a total of 91 samples were measured and analyzed...

During the 2020–2021 summit eruption of Kīlauea volcano, Island of Hawaiʻi, staff at the U.S. Geological Survey Hawaiian Volcano Observatory (HVO) conducted 17 helicopter overflights of the eruption area between the dates of 21 December 2020 and 8 June 2021. Images captured during these flights were processed using the structure-from-motion (SfM) photogrammetry technique to produce...

This data release includes metadata and tabular data that documents the response of ohia (Metrosideros polymorpha) and ambrosia beetles (Curculionidae, Xyleborini) following the intentional inoculation of healthy ohia to Ceratocystis lukuohia, one of two fungal pathogens that causes Rapid Ohia Death (ROD). Ohia were inoculated with the ROD pathogen at three sites differing in elevation...
