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.

pydrip - Software to manage and update data for DRIP pydrip - Software to manage and update data for DRIP
This package handles retrieval and preparation of the source data for DRIP. Source data currently come from two sources. The Dam Removal Science Database is distributed by USGS in ScienceBase (https://doi.org/10.5066/P9IGEC9G) and a complete list of dam removals is distributed by American Rivers in Figshare. We provide these efforts as a package in order to support full transparency on...
Borehole Erosion Test data, Lower American and Sacramento Rivers, California, 2019 (ver. 3.0, July 2020) 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...
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 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...
Geochemistry, geochronology, and isotope geochemistry data for rocks and zircons from Mountain Pass, California 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 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...
Water-quality and preceding precipitation data for low-flow and storm runoff samples collected in Johnson County, Kansas, from January 2015 through November 2018 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...
