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.

Stream heat budget model input and scripts for simulating groundwater and thermal equilibrium controls on annual paired air-water temperature signal transport in headwater streams Stream heat budget model input and scripts for simulating groundwater and thermal equilibrium controls on annual paired air-water temperature signal transport in headwater streams
We investigated the relative importance of groundwater (GW) and other local heat budget processes on downstream annual stream temperature signal characteristics using deterministic heat budget model (HFLUX) scenarios within an idealized stream reach representative of mountainous forested conditions. The purpose of this data release is to provide additional supplemental information for a...
Radiocarbon age dating of biological material from cores collected off British Columbia, Canada and southeastern Alaska, U.S. along the Queen Charlotte-Fairweather fault zone Radiocarbon age dating of biological material from cores collected off British Columbia, Canada and southeastern Alaska, U.S. along the Queen Charlotte-Fairweather fault zone
Results of radiocarbon age dating of planktic foraminifera, benthic foraminifera, and pelecypod shell fragments collected from piston cores, trigger weight cores, and IKU grab samples obtained in 2015 and 2017 offshore British Columbia, Canada and southeastern Alaska, U.S. along the Queen Charlotte-Fairweather fault zone.
Near-field Remote Sensing of River Velocity, Stage, and Precipitation during Portions of 2015 in Waldo Canyon, Colorado, USA Near-field Remote Sensing of River Velocity, Stage, and Precipitation during Portions of 2015 in Waldo Canyon, Colorado, USA
The sensor ensemble (DEbris and Floodflow Early warNing System, DEFENS) was deployed in Waldo Canyon, Pike National Forest, Colorado, which was burned during the Waldo Canyon fire in the summer of 2012. The ensemble consists of noncontact, ground-based (near-field), Doppler velocity (velocity) and pulsed (stage or gage height) radars, rain gages, and a redundant radio communication...
Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2024 Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2024
These datasets provide early estimates of 2024 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from April to late June. Typically, the EAG estimates are publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contains five fractional cover maps along with their...
Plumeria Simulations of 20 December 2020 Kīlauea Volcano Eruption Plume Plumeria Simulations of 20 December 2020 Kīlauea Volcano Eruption Plume
This data release contains results of model simulations of a plume at Kilauea volcano that occurred on 20 December 2020. The ash-poor plume was produced when lava flowed into a water lake at the summit of Kilauea volcano. Simulations were conducted to constrain the conditions under which the plume rose to its observed height. The analysis and results are described in the accompanying...
