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.

Borehole Erosion Test data, Lower American and Sacramento Rivers, California, 2019 (ver. 3.0, July 2020)
Borehole erosion tests were performed to quantify sediment erosion rates as a function of depth below grade and flow speed at locations along the Sacramento and American Rivers in 2019. The dataset consists of: - borehole caliper files describing the initial geometry of the borehole, and its shape after each test flow event, - where available, a digital time series describing discharge into the ho
Operation of an electrical barrier to block sea lamprey in the Black Mallard, Michigan, detailing stream temperature, conductivity, discharge, electric field intensity, and animals trapped and killed during 2016, 2017, and 2018
Sea lamprey (Petromyzon marinus) control is achieved in tributaries to the Laurentian Great Lakes by applying lamprey-specific pesticides (lampricide) to habitats containing larval sea lamprey. Lampricide treatments are cheaper and more effective in watersheds where dams block runs of adult sea lamprey and hence limit the distribution of sea lamprey larvae. However, dams impound water and those wi
Geochemistry, geochronology, and isotope geochemistry data for rocks and zircons from Mountain Pass, California
This dataset contains geochemical, geochronologic, and isotopic data collected for rocks and zircons from Mountain Pass, California, USA. See accompanying Economic Geology publication described in the "Larger Work" section of this metadata file for a detailed description of this dataset.
Kaguya Terrain Camera Ames Stereo Pipeline Generated Digital Terrain Models of the Moon
This is a digital terrain model (DTM) extracted from Kaguya Terrain Camera (TC)stereo images from the Japan Aerospace Exploration Agency (JAXA) SELenological and ENgineering Explorer (SELENE) mission. The original data product is a DTM from stereo images acquired at approximately 10 meters/pixel resolution, which allows an output DTM post spacing of 35 meters/pixel. The DTM was generated using the
Water-quality and preceding precipitation data for low-flow and storm runoff samples collected in Johnson County, Kansas, from January 2015 through November 2018
This U.S. Geological Survey (USGS) Data Release provides selected discretely measured water-quality data collected from 27 monitoring sites in Johnson County, Kansas, during January 2015 through November 2018. Water-quality samples were analyzed for nutrients, Escherichia coli bacteria, total suspended solids, suspended-sediment concentration, and chlorophyll as part of a study to assess the water
Data from Decadal Change in Groundwater Quality Web Site, 1988-2020
Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later between 20
Genotypes of Atlantic Sturgeon collected from Canada to Georgia used in the development of a genetic baseline
This dataset includes microsatellite genotypes for 2510 Atlantic sturgeon from 18 different populations distributed from Canada to Georgia. Each individual was genotyped at 12 loci. Additional information about sex, capture date, and size are also provided.
Behavior of female adult Pacific lamprey (Entosphenus tridentatus) exposed to natural and synthesized odors
We investigated the behavioral response of female Pacific lamprey to three odors and to differences in water flow. Adult lamprey were challenged with: 1) washings from conspecifics, 2) with washings from adult males, and 3) with an artificial odor that mimicked a component of a natural lamprey pheromone. In addition, we conducted parallel tests to check for rheotaxis. The fish were tested in two Y
Data from a reactive transport modeling study of cave seepage water chemistry
Karst systems are useful for examining spatial and temporal variability in Critical Zone processes because they provide a window into the subsurface where waters have interacted with vegetation, soils, regolith, and bedrock across a range of length and time scales. The majority of Critical Zone research has emphasized silicate lithologies, which are typified by relatively slow rates of reactivity
Slow-moving landslides near the U.S. West Coast mapped from ALOS and ALOS-2 InSAR, 2007-2019
This data set provides a polygon shapefile delineating relatively large, slow-moving (4-17 cm/year in the radar line-of-sight direction) landslides in the continental U.S. western coastal states (California, Oregon, and Washington). The polygons also are provided in a Google Earth .kmz file. Delineated landslides were identified from displacement signals captured by InSAR (Interferometric Syntheti
Uranium- and thorium-isotope data used to estimate uranium-series ages of Pleistocene lake deposits in the Lake Manix basin, Mojave Desert, California
This data release contains numerical U- and Th-isotopic data used to calculate uranium-series age estimates and initial 234U/238U activity ratios for samples of carbonate-rich clast coatings, oncoidal tufa rinds, calcite-replaced rhizoliths, carbonate nodules, and ostracod shells from sites associated with different lake levels of paleo Lake Manix near Barsow, CA. In addition, measured U concentra
Tops file for the Mowry Shale and associated strata in the Wind River Basin, Wyoming
The Wind River Basin is a structural and sedimentary basin that formed during the Laramide orogeny in latest Cretaceous and early Eocene time. The basin encompasses about 7,400 square miles in central Wyoming and is bounded by the Washakie, Owl Creek and Bighorn uplifts on the north, the Casper arch on the east, the Granite Mountains uplift on the south, and Wind River uplift on the west (fig. 1).
