Computed tomography (CT) scans, photographs, X-ray fluorescence (XRF) scans, geochemistry, X-ray diffraction (XRD), and gamma-ray bulk density data of push cores from Loki's Castle and Favne vent fields, Mohns Ridge
This data release contains computed tomography (CT) scans, photographs, X-ray fluorescence (XRF) scans, geochemical data, X-ray diffractograms (XRD), and gamma-ray bulk density of push cores and sediment subsamples from those cores collected in 2018 and 2019 from Loki’s and Favne Vent Fields, Mohns Ridge, part of the Arctic Mid-Atlantic Ridge. For the geochemical section of the release, data inclu
Monitoring Data to Support the Operation of the Electric Dispersal Barrier System on the Chicago Sanitary and Ship Canal at Romeoville, Illinois, October 1, 2017, to September 30, 2018
The U.S. Geological Survey monitors water surface flow reversals, commercial vessel traffic, and temperature and specific conductance in the U.S. Army Corps of Engineers Electric Dispersal Barrier System, EDBS, on the Chicago Sanitary and Ship Canal, Chicago, Illinois. This data release is the 2018 water year summary of the EDBS monitoring data. Water surface flow reversals at the EDBS are monitor
Time-series measurements of oceanographic and water quality data collected at Thompsons Beach and Stone Harbor, New Jersey, USA, September 2018 to September 2019 and March 2022 to May 2023
In October 2012, Hurricane Sandy made landfall in the Northeastern U.S., affecting ecosystems and communities of 12 states. In response, the National Fish and Wildlife Federation (NFWF) and the U.S. Department of Interior (DOI) implemented the Hurricane Sandy Coastal Resiliency Program, which funded various projects designed to reduce future impacts of coastal hazards. These projects included mars
Generalized lithology for lithogeochemical classification of the bedrock of Vermont
This data release provides a generalized lithology look-up table for the lithogeochemical classification of Vermont's bedrock geologic map units. The table is defined from the mapped bedrock geologic units published by Ratcliffe and others (2011) and the generalized lithology of rock group A and rock group B for lithogeochemical classification as defined by Robinson and Kapo (2003). The 2003 class
U-Pb Dataset from late Paleozoic record of the Eastern Shelf of the Permian Basin
This dataset accompanies planned publication titled "The Far-Field imprint of the LPIA, its demise, and the onset of a dust-house climate across the Eastern Shelf of the Permian Basin". Zircon ages presented in this dataset are from rocks collected across the eastern margin of the Permian Basin, Texas. The U-Pb zircon ages are used to investigate changes in provenance in this region as a result of
Catch and Biomass per unit effort of fishes in two Northern Wisconsin lakes from 2017-2021
Inland lake ecosystems are transforming due to unprecedented effects of climate changes and disturbance along riparian habitat, diminishing their potential to support fisheries. Walleye Sander vitreus, the most sought-after game fish in north-central North America supporting robust recreational and tribal fisheries, have declined. Climate change, harvest, invasive species, and concurrent increases
Autonomously Collected Benthic Imagery for Substrate Prediction, Lake Michigan 2020-2021
These data consist of down-looking images of Lake Michigan benthos, collected in 2020 and 2021 with an autonomous underwater vehicle (AUV). Information about each image (i.e., latitude, longitude, depth from surface, altitude, roll, pitch, yaw, and creation time) can be found in the associated csv file. Substrate type was divided into 9 classes based on the Coastal and Marine Ecological Classifica
Chronology of recent volcanic activity on the Island of Hawai‘i, Hawaii
The youngest and largest island in the State of Hawaii—the Island of Hawai‘i—is formed by five volcanoes, three of which have erupted within recent geologic history: Mauna Loa, Kīlauea, and Hualālai. This data release provides a chronology for activity and impacts at Mauna Loa, Kīlauea, and Hualālai over approximately the past two and a half centuries. This data release includes a word document, “
Geological mapping coordinates, and zircon geochemistry, geochronology and isotope geochemistry data, Bobcat Hills, California
This dataset contains geologic mapping coordinates, and geochemical, geochronologic, and isotopic data collected for shonkinite dikes and zircons from Bobcat Hills, California, USA. See accompanying G-Cubed publication described in the "Larger Work" section of this metadata file for a detailed description of this dataset.
MODFLOW 6 model used to simulate groundwater flow in the Harney Basin, southeastern Oregon (ver. 2.0, May 2024)
A three-dimensional groundwater flow model, MODFLOW 6, was developed to provide a better understanding of the hydrogeology of the Harney Basin, southeastern Oregon. The model was used to investigate the historical groundwater-level decline and storage loss associated with anthropogenic groundwater demands. The model was calibrated to 1930 through 2018 conditions. This USGS data release contains al
Response of natural phytoplankton communities from Green Bay (Lake Michigan) and Maumee Bay (Lake Erie) to laboratory manipulations of nutrient and trace metal availability during late summer 2018
Microcystins (MC) are a class of cyanotoxins produced by many cyanobacteria taxa. Although toxic to metazoans, the evolution of microcystin pre-dates the appearance of metazoans, and so MC did not originate as a toxin to potential metazoan grazers. One hypothesized functional role of microcystin is the management and acquisition of metals, several of which form complexes with MC intracellularly. M
Biofouling and mussel growth from mussels deployed in Great Lakes embayments (2013-2016)
Many taxa of North American unionid mussels are imperiled due to biofouling by invasive dreissenid mussels. Here, we report on biofouling rates of unionid mussels suspended in cages during the growing season in nearshore embayments in Lake Erie (2013-2016), Lake Michigan (Green Bay 2016, Grand Traverse Bay 2015) and Lake Huron (Saginaw Bay 2015). Mussels were deployed in early summer (late May or
