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.

Suspended-Sediment Data for the Yakima River at Kiona (USGS 12510500), Washington, June 2018 through September 2022 Suspended-Sediment Data for the Yakima River at Kiona (USGS 12510500), Washington, June 2018 through September 2022
This data release summarizes discrete suspended-sediment concentration (SSC) measurements and continuous estimates of SSC for the Yakima River at Kiona (USGS 12510500) for the period between June 01, 2018 and September 30, 2022. Continuous estimates of SSC were derived primarily through calibrated turbidity records. These data were collected to support a better understanding of how water...
Lidar Point Clouds (LPCs), Digital Elevation Models (DEMs), and Snow Depth Raster Maps Derived from Lidar Data Collected on Small, Uncrewed Aircraft Systems in the Upper Colorado River Basin, Colorado, 2020-22 Lidar Point Clouds (LPCs), Digital Elevation Models (DEMs), and Snow Depth Raster Maps Derived from Lidar Data Collected on Small, Uncrewed Aircraft Systems in the Upper Colorado River Basin, Colorado, 2020-22
This data release consists of three child items distinguishing the following types of data: light detection and ranging (lidar) point clouds (LPCs), digital elevation models (DEMs), and snow depth raster maps. These three data types are all derived from lidar data collected on small, uncrewed aircraft systems (sUAS) at study areas in the Upper Colorado River Basin, Colorado, from 2020 to...
Geology of the Grandfather Mountain Window and Vicinity, North Carolina and Tennessee Geology of the Grandfather Mountain Window and Vicinity, North Carolina and Tennessee
The Blue Ridge belt in northwestern North Carolina and northeastern Tennessee is composed chiefly of 1,000-million to 1,100-million-year-old metamorphic and plutonic rocks that have been thrust many miles northwestward across unmetamorphosed Cambrian(?) and Cambrian sedimentary rocks of the Unaka belt. The Blue Ridge thrust sheet is rooted on the southeast along the Brevard zone, a zone...
Human use and activities at two urban riparian forest restoration sites in Indiana, USA, May-Sept, 2016 Human use and activities at two urban riparian forest restoration sites in Indiana, USA, May-Sept, 2016
The data consists of date and time of use, activity and number of individuals visiting specific sites. This data was collected by using camera traps to monitor visitors of two mitigation areas that are being restored to riparian forests.
Infection prevalence and viral load in pacific herring exposed to erythrocytic necrosis virus (ENV) at 3 temperatures Infection prevalence and viral load in pacific herring exposed to erythrocytic necrosis virus (ENV) at 3 temperatures
Viral erythrocytic necrosis (VEN) is a disease of marine and anadromous fishes, which is poorly understood, largely because its causative iridovirus, erythrocytic necrosis virus (ENV), is intractable to cell culture. Natural VEN epizootics and observations studies in wild populations suggest that temperature may be an important disease cofactor. Here, a controlled laboratory exposure...
Alternative complement pathway assay data for adult largemouth bass exposed in outdoor ponds to 17alpha-ethinylestradiol or an estrone-atrazine mixture Alternative complement pathway assay data for adult largemouth bass exposed in outdoor ponds to 17alpha-ethinylestradiol or an estrone-atrazine mixture
Alternative complement pathway assay data observed in adult largemouth bass plasma in response to an EE2 (17alpha-ethinylestradiol) or mixture of estrone and atrazine exposure under laboratory pond conditions, with associated fish identification information.
