Rivers are some of the most dynamic features of the Arctic landscape, yet their role in the global carbon cycle is poorly understood. Researchers are still unraveling the intricacies of how river dynamics control organic carbon (OC) accumulation, transport, and degradation in riverine systems. The interplay between permafrost thermal state in river corridors, snow and ice-affected...

This dataset contains Interferometric Synthetic Aperture Radar (InSAR) observations acquired during the 2024–2025 diking episode along the Fentale-Dofen segment of the Ethiopian Rift. The data were collected to image ground deformation associated with magmatic intrusion and faulting processes in an active rift system. The dataset includes wrapped interferograms measuring line-of-sight...

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.

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...
