Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Interferometric Synthetic Aperture Radar (InSAR) Data for the 2024–2025 Diking Episode, Fentale-Dofen Segment, Ethiopian Rift Interferometric Synthetic Aperture Radar (InSAR) Data for the 2024–2025 Diking Episode, Fentale-Dofen Segment, Ethiopian Rift
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...
Gamma ray spectrometry measurements of Ordovician strata at Tumbling Run, Virginia Gamma ray spectrometry measurements of Ordovician strata at Tumbling Run, Virginia
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...
Natal Origin of Juvenile Salmon Collected on Middleton Island, Alaska, 2010-2024 Natal Origin of Juvenile Salmon Collected on Middleton Island, Alaska, 2010-2024
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...
Topo-bathymetric datasets in the Santiam River Basin, Oregon Topo-bathymetric datasets in the Santiam River Basin, Oregon
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...
2018 Stream Ecology Data for Proglacial Rivers in Alaska to Support Research on Effects of Loss of Meltwater from Glaciers and Snowpack on River Habitat 2018 Stream Ecology Data for Proglacial Rivers in Alaska to Support Research on Effects of Loss of Meltwater from Glaciers and Snowpack on River Habitat
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.
Multitemporal Seasonal Tabular Data Products Derived from Landsat Imagery for the Selected Ciénegas and Surrounding Floodplains of the Greater Madrean Archipelago Ecoregion, 1985-2023 Multitemporal Seasonal Tabular Data Products Derived from Landsat Imagery for the Selected Ciénegas and Surrounding Floodplains of the Greater Madrean Archipelago Ecoregion, 1985-2023
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...
