This dataset includes gamma ray spectrometry measurements from exposed Ordovician mixed carbonate and siliciclastic strata near Tumbling Run, Virginia; a regionally recognized reference section within the central Appalachians. Gamma ray measurements were collected on a continuous assay with a thirty second collection interval by walking one meter from the outcrop face using a GF...

This dataset provides origin (hatchery vs. wild) and energy density (kJ g-1) of juvenile pink (Oncorhynchus gorbuscha) and chum salmon (O. keta) from the eastern Gulf of Alaska, 2010–2024. Juvenile salmon were sampled from rhinoceros auklet (Cerorhinca monocerata) diets on Middleton Island (59.4375 N, 146.3277 W) located near the continental shelf break in the Gulf of Alaska. Auklets...

In 2023, the USGS 3D Elevation Program (3DEP) funded the collection of topo-bathymetric lidar (sometimes referred to as "green lidar") in the Santiam River Basin, Oregon. As part of this acquisition, lidar data were collected on the North, Middle and South Santiam and Santiam Rivers, encompassing reaches upstream of Detroit, Green Peter and Foster Lakes on each river and extending...

This dataset contains CSV files for raw and processed stream biological data used in an analysis of temporal synchrony of proglacial rivers. Data include water quality metrics, fish survey data, and biomass calculations.

Digital flood-inundation maps for a 2.7-mile reach of Rio Grande De Loiza in and near Caguas, Puerto Rico, were created by the U.S. Geological Survey (USGS) with funding from the U.S. Geological Survey Supplemental Oversight Team which received funding for this effort through Title VII of Division N in the Consolidated Appropriations Act, 2023 (Public Law 117–328). Flood profiles were...

Ciénegas are wetlands in arid and semi-arid regions of North America. We quantified changes in ciénega condition and floodplain dynamics using the detailed boundaries of 31 ciénegas and their respective controls.This data release is a series of four data collections consisting of 68 tabular data files (.csv) that include the following: (i) “i_Cienega_Timeseries_CSVs.zip” data collection...

These Holocene aged samples are from three sediment cores obtained near the Provincetown Hook spit in Cape Cod, Massachusetts. The goal of the geochronology work is to determine when shoreface sediments, which represent the oceanward extent of the spit, were present at the surface for the Provincetown Hook. Results from this work support efforts to publish more recent sedimentological...

This dataset describes environmental DNA (eDNA) sample collections, DNA extractions, and DNA copy numbers (abundance of environmental DNA) for cisco Coregonus artedi, a native prey fish of restoration interest in the Laurentian Great Lakes, in tributaries to Lake Huron’s North Channel in Canada. Samples were collected during cisco spawning runs (mid-November) from 2022-2024.

This data set includes metadata for fish and microbes from water samples collected in southern Lake Michigan in August 2021. All field eDNA samples were collected using a Tethys-class Long Range Autonomous Underwater Vehicle (LRAUV) carrying an eDNA sampler, the 3G Environmental Sample Processor (ESP). Water samples were collected at various depths within following target layers: the...

We used visual encounter surveys (VES) and environmental DNA (eDNA) surveys for amphibians in the western united states. Data are results of both VES and eDNA surveys for all amphibian species that occur in the locations surveyed.

Craig County, Virginia hosts large (>500 m wide) blockslides and rock slumps along the southeastern slopes of several mountains. These features differ from Virginian boulder fields in several aspects, most significantly in soil development, foliage, and clast size. In contrast with freshly exposed, likely periglacial, boulder fields that commonly contain centimeter to meter-sized...

Glacial and proglacial landscapes provide critical sources of water and solutes to downstream riverine and marine ecosystems. This dataset contains samples from the dominant landscape types in the Nellie Juan River basin, collected from surface streams, groundwater, rain, and snow. Water samples were also collected from streams near the Exit, Gulkana, and Kennicott Glaciers. Snow samples...
