The Maumee River network contributes a significant amount of total phosphorus (P), including both sediment-bound P (sed-P) and dissolved P, to the Western Lake Erie Basin. Most Maumee River headwater streams are agricultural, with conservation management focused on limiting sediment and nutrient transport from cropland to the stream network. However, several studies have shown streambank...

Data include total nitrogen and carbon, carbon species, total metal, and particle-size analyses of soft streambed sediment from Little Flatrock Creek, Paulding County, Ohio. These data will be used in a sediment-source mixing model to attribute the proportional contribution of individual sources to suspended sediment in the basin. Source samples were identified as one of four land-cover...

Data include total nitrogen and organic carbon, total metal, and particle-size analyses of upland (cropland, woodland, gullies, roads) and streambank from the East River basin, Brown County, Wisconsin that was collected in July and August 2022. These data will be used in a sediment-source apportionment tool to attribute the proportional contribution of individual sources to suspended...

These data are bathymetry (river bottom elevation) and depth-averaged velocities generated from the November 9–10, 2021, survey of the Barkley Dam tailwater from just downstream from Barkley Dam to approximately 600 feet upstream from the US 62 bridge (about 0.8 mile total length). Bathymetry and velocity data were collected using an acoustic Doppler current profiler (ADCP) with an...

A Smart Dynamic Cone Penetrometer (DCP) system allows for the partially automated collection of cone penetrometer data (CPT) to determine mechanical properties of soil along a vertical profile. A smart DCP system was used to collect soil penetration-with-depth values at 19 sites across the mountainous regions of Puerto Rico. The 19 sites were co-located at the United States Geological...

This dataset includes sediment temperature data collected from seven locations within the Big Soos creek basin from July 2023 to July 2024. Data collection took place at two locations on Covington Creek and Big Soos Creek, and single locations on Jenkins Creek, Little Soos Creek, and Soosette Creek. See "BigSoos.sites.csv" for field IDs, descriptions, and locations of these seven sites...

We present isotopic and geochemical data for several Archean and Paleoproterozoic metamorphic rocks in the Penokean orogen, USA. These data include new U-Pb and trace element analyses of apatite, titanite, and monazite; bulk rock major and trace element compositions; and whole rock and garnet Lu-Hf and Sm-Nd isotope compositions.

This data release includes hydroacoustic data for the 2023 to 2025 water years at one station. This station is part of a discrete and continuous monitoring project in embayments on Long Island Sound to support nutrient management activities in Connecticut. The data were collected by the U.S Geological Survey (USGS) in cooperation with the Connecticut Departments of Energy and...

In this data release we present zircon U-Pb ages and εHf(t), feldspar 40Ar/39Ar ages, and whole rock major and trace elemental abundances to constrain the Morrowan-Atokan Boundary, the timing of onset of high-frequency cycles and the redox and salinity changes associated with rapidly changing depositional environments within the Arkoma Basin. Zircon and sanidine data were collected from...

Earthquake ground motions are modified by local geologic site conditions. Soft soils and basin sediments may amplify and prolong the duration of ground shaking, necessitating site characterization to improve existing ground motion predictions and seismic hazard analyses. Horizontal-to-Vertical Spectral Ratio (HVSR) measurements distinguish one or more site resonant frequencies and the...

Fort Irwin National Training Center uses treated groundwater for both drinking and irrigation purposes. Wastewater is treated locally at Fort Irwin National Training Center using tertiary treatment methods and the treated wastewater effluent is discharged into percolation ponds and allowed to percolate into the local groundwater system. Specific conductance, total dissolved solids...
