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.

Tracking data for Red-faced cormorants (Phalacrocorax urile)

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 2 satellite transmitters attached to Red-faced cormorants on Attu Island Alaska, 2006. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content) contain the raw Argos DIAG (D

Tracking data for Pelagic cormorants (Phalacrocorax pelagicus)

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 8 satellite transmitters attached to Pelagic cormorants on Middleton and Attu Islands, Alaska, 2000-2006. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content) contain th

National Hydrologic Model Alaska Domain parameter database, version 1

This data release contains input data for hydrologic simulations of the Alaska Domain application of the U.S. Geological Survey (USGS) Precipitation Runoff Modelling System (PRMS) as implemented in the National Hydrologic Model (NHM) infrastructure (Regan and others, 2018). The NHM Alaska Domain parameter database consists of 114 parameter files in ASCII format (CSV), two files needed to run the A

Depth-to-water data and calculated vertical hydraulic gradient at the sediment-water interface in Upper Klamath Lake, Oregon, 2017

Ten groundwater piezometers and lake-level stilling wells were deployed in Upper Klamath Lake (UKL), Oregon during May through October 2017. Piezometers and stilling wells were deployed in pairs so that water levels could be measured relative to a common measuring point (MP) at each location. Piezometers were installed in the lakebed sediment, with screens from 3.92 to 4.92 feet below the sediment

Data release for the Land Change Causes for the United States Interior Highlands (2001 to 2006 and 2006 to 2011 time intervals)

These data were created to describe the causes of land cover change that occurred in the Interior Highland region of the United States for the time intervals of 2001 to 2006 and 2006 to 2011. This region, which covers approximately 17.5 million hectares, includes portions of the U.S. states of Arkansas, Missouri, Oklahoma, and Kansas. Most of the area is covered by gently rolling hills of forests

Stream habitat relations of the Yellowcheek Darter (Etheostoma moorei) among four forks of the Little Red River in Arkansas

The Yellowcheek darter (YCD), Nothonotus moorei (Robison and Buchanan 2020), is endemic to the headwater tributaries (a.k.a. ‘forks’) of Little Red River system (South Fork, SF; Middle Fork, MF; Archey Fork, AF; and Beech Fork, BF) in north central Arkansas. Large portions of critical stream habitat in each stream fork were inundated in 1964 with the construction of Greers Ferry Dam, and the YCD i

Bathymetry of Morse and Geist Reservoirs in Central Indiana, 2016

These data are high-resolution bathymetry (lake bottom elevation) in a gridded XYZ format, generated from hydrographic surveys of Morse and Geist Reservoirs in April and May of 2016. Hydrographic data were collected using a multibeam echo-sounder (MBES) with integrated inertial navigation solution (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the lake along s

Mercury Concentrations and Isotopic Compositions in Sediment Cores from North American Lakes (Alaska, Minnesota, and Newfoundland)

Mercury isotope measurements were made across nine sediments cores from remote North American lakes to examine changes in the Hg isotope profiles. The lakes spanned regions of Alaska, Minnesota, and Newfoundland as well as a range of temperate to arctic climates. This data describes the natural record of mass dependent (MDF) and mass independent (MIF) Hg isotope fractionation related to deposition

Data for the report Geologic Framework and Hydrogeology of the Middle Carson River Basin, Eagle, Dayton, and Churchill Valleys, West-Central Nevada

This USGS data release represents the data from the following publication: Maurer, D.K., 2011, Geologic framework and hydrogeology of the middle Carson River Basin, Eagle, Dayton, and Churchill Valleys, West-Central Nevada: U.S. Geological Survey Scientific Investigations Report 2011–5055, https://doi.org/10.3133/sir20115055.

Hawai'i Rapid 'Ohi'a Death Decontamination 2019-2020

Rapid 'Ohi'a Death is a fatal disease caused by Ceratocystis lukuohia and C. huliohia that are decimating Hawai'i's keystone trees species, 'ohi'a (Metrosideros polymorpha). We developed practical and effective decontamination practices for both cultured C. lukuohia and C. huliohia as well as Ceratocystis spores embedded in ambrosia beetle frass (fine particles of macerated wood or boring dust, be

Inventory of landslides triggered by rainfall on 16-17 January 2019, Los Angeles County, CA

This dataset contains 286 landslide polygons mapped after a rainstorm on 16-17 January 2019. The majority of the landslides are located in the burn areas of the 2016 San Gabriel Complex fire, the 2014 Colby fire, and the 2009 Morris fire. A smaller number of additional landslides were located in nearby unburned areas. More information about the burn perimeters associated with this inventory and t

Mercury speciation and other constituent data for surface water and bed sediment associated with the Hamilton Airfield Wetland Restoration, Navato, California. USA.

The Hamilton Wetland Restoration Project (HWRP) is a joint venture between the US Army Corps of Engineers (USACE; San Francisco District) and the California State Coastal Conservancy. The site is located on the property of the former Hamilton Army Airfield in Novato, California, along the western edge of San Pablo Bay, which is part of northern San Francisco Bay. The initial stages of wetland rest
