Data

This data release contains updated monthly and annual water-use estimates from the Aquaculture and Irrigation Water-Use Model (AIWUM) version 2.0 for the Mississippi Alluvial Plain (MAP) from 2014 to 2023. AIWUM version 2.0 employs remote sensing datasets and machine learning to advance the ability to predict groundwater use in regions with scarce or limited in-situ groundwater...

Since 1975, annual water use for Louisiana has been published on a 5-year basis and is used for a variety of purposes. As the Sparta aquifer is a heavily used aquifer, is the sole source of groundwater for many parishes in Louisiana, and recent withdrawals have exceeded the Sparta’s natural recharge, a more frequent compilation of water usage for the Sparta aquifer in Louisiana is needed...

To understand how aquatic macroinvertebrate assemblages vary among side channels across a large floodplain river ecosystem, we collected macroinvertebrates from 23 side channels distributed across six reaches of the Upper Mississippi River and Illinois River and quantified taxonomic and functional indices. Within this data release, three products are included: 1) site-level environmental...

Aquatic reflectance data from Sentinel-2 satellite imagery is paired with discrete chlorophyll measurements across Oregon, Ohio, and Florida in the United States. The dataset contains a csv data file (CyAN_S2_Matched_WQ_S2.csv), a csv data dictionary file (CyAN_S2_Matched_WQ_S2_data_dictionary.csv) that describes each of the columns in the data file, and a zip file of python scripts...

The U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program has actively collected geophysical and sedimentological data in the northern Gulf of America (Gulf of Mexico) for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s, most HRSP data were collected in analog format as...

Ar/Ar data are for 1 sample that constrains the cooling age of biotite. The geochronology provides time constraints for the age of gold mineralization in the Tuvatu Gold Mine in Fiji. Samples were provided by Thomas Monecke (Colorado School of Mines). Samples were analyzed in January 2024.

Understanding the eruptive histories and petrogenetic models that underpin hazard assessments at active volcanoes typically requires high-precision ages for late Pleistocene to Holocene lava flows. These data vary in quality, typically related to textural and chemical variations in lava flow samples. These samples were part of an existing 40Ar/39Ar dataset for andesitic-dacitic rocks...

We developed numerous datasets describing mining activity and landscape conditions for all known active, inactive, abandoned, and legacy surface mines in the Eastern United States Appalachian region to support monitoring and regulatory needs. These data include 1) a study area boundary, 2) a compiled set of spatial footprints for known mines from federal, state, academic research, and...

Fathead minnows (Pimephales promelas) exposures to water containing per- and polyfluoroalkyl compounds (PFAS) related to aqueous film-forming foam used in extinguishing fires were performed on-site at the USGS Toxic Substance Hydrology Groundwater Research Site on Cape Cod, MA. In 2019, to investigate potential effects on reproductive parameters, exposures were performed for either 7 or...

Laboratory data were collected in 2021 on live fathead minnow sperm motilities by using computer assisted sperm motion analysis. Flow cytometry data were collected on the testicular cells; data are in standard format that allows files created by one type of acquisition hardware and software to be analyzed by any other type. This study on potential reproductive effects was performed in...
