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.

Particulate physicochemical data at a fish hatchery in Puyallup, Washington, September 2023 Particulate physicochemical data at a fish hatchery in Puyallup, Washington, September 2023
Particulate samples were collected from a fish hatchery in Puyallup, Washington, September 18 – 20, 2023 during late summer, low-flow conditions in the intake creek. Settled solids were collected from a retention pond and from the incubation room trough. The trough solids likely had been deposited during storm events the previous winter. A third sample was collected in the incubation...
Physical and chemical data for dust deposited on Colorado Rocky Mountain snow cover during water year 2013 through water year 2016. Physical and chemical data for dust deposited on Colorado Rocky Mountain snow cover during water year 2013 through water year 2016.
Atmospheric particulate matter deposited to snow cover diminishes snow-surface albedo and results in early onset and rapid snow melting, challenging management of downstream water resources. We present here physical and chemical data from snow samples from 14 sites during the melt seasons of water years 2013-16 across 60,000 km2 of the central Rocky Mountains within the Upper Colorado...
Buff-breasted Sandpiper Migration Surveys in the Western Gulf Coastal Plain of Texas and Louisiana (2017-2019) Buff-breasted Sandpiper Migration Surveys in the Western Gulf Coastal Plain of Texas and Louisiana (2017-2019)
These data were collected using distance sampling methods (point counts) and visual assessment of land cover and habitat at randomly selected locations in the Western Gulf Coastal Plain ecoregion of Texas and Louisiana in April-May 2017-2019.
Enhanced Terrain Imagery of the Elkins 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution Enhanced Terrain Imagery of the Elkins 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Elkins 30 x 60 minute quadrangle in Virginia and West Virginia. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2015 and 2021. The data were processed using...
