The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

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...

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...

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...

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...

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...

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...

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

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...

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.

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...

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...
