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.

Ecological modeling output for the Everglades Agricultural Area Reservoir 2020
Ecological models facilitate evaluation and assessment of alternative approaches to restore the Greater Everglades ecosystem. The models of particular interest to the South Florida Water Management District for planning for the Everglades Agricultural Area (EAA) Reservoir were: (1) Cape Sable Seaside Sparrow Marl Prairie Indicator, (2) Florida apple snail (native) population model (EverSnail), (3)
Lake Hermitage Marsh Creation? NRDA Early Restoration Project: 2018 and 2020 land-water classifications
The Louisiana Coastal Protection and Restoration Authority and the Natural Resource Damage Assessment (NRDA) develop restoration plans in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arrestin
Synthesis of Gulf Coast Management Plans and Restoration Project Values, Stressors, and Strategies (2020-2021)
Dataset of segments (e.g. phrases, sentences, paragraphs) associated with ecological values, human community values, stressors, or restoration strategies found within Gulf Coast state management plans and restoration project descriptions, collected 2019-2020.
Biomarkers of laboratory-exposed Northern Leopard frogs to neonicotinoids: DNA cell cycle, fragmentation, and genome size
Data were collected on whole blood DNA parameters including cell cycle, DNA fragmentation, and genome size obtained from Northern leopard frogs exposed to neonicotinoid insecticides in the laboratory. Data consist of flow cytometry files that were generated in the analysis of the frog blood.
Serum osmolality, cortisol, and protein in laboratory common carp (Cyprinus carpio)
Common carp were placed into three treatment groups based on levels of induced stress in the laboratory setting. Measurements of common carp blood serum cortisol and serum protein were collected by spectrophotometry. Additionally, serum osmolality measurements were obtained by vapor pressure osmometry. Fish weights were taken at the time of blood collection.
Laboratory analysis assessing immune response after flame retardant exposure in American kestrels, Falco sparverius, through 21 days post-hatch
Laboratory analysis of innate American kestrel, Falco sparverius, immune response after exposure to flame retardant, isopropylphenyl phosphate (ITP) through 21 days post hatch. Data consist of flow cytometry files that were generated in the analysis of white blood cells from kestrel blood. Thus, data are in standard format that allows files created by one type of acquisition hardware and software
Database of Groundwater Levels and Hydrograph Descriptions for the Nevada Test Site Area, Nye County, Nevada (ver. 5.0, February 2022)
This data release consists of a Microsoft Access database and Microsoft Excel workbook that contain water-level data and other hydrologic information for wells in and near areas of underground nuclear testing at the Nevada Test Site (currently the Nevada National Security Site). The database provides information for each well (well construction, borehole lithology, units contributing water to the
Lead (Pb) in Bald and Golden Eagles from 38 United States, USA, 2010-2018
We evaluated lead poisoning in bald and golden eagles during all seasons of the year and from states in each of the four major flyways throughout the continental USA.
Geothermal slide-hold-slide experiments on bare surface Westerly granite
Laboratory slide-hold-slide tests, combined with flow through tests, conducted on Westerly granite with 30 degree sawcut. Tests were conducted with a constant confining pressure of 30 MPa with an average pore pressure of 10 MPa at temperatures of 23 and 200 degC. Three fluid flow conditions were examined (1) no flow, (2) cycled flow, and (3) continuous flow.
Juvenile Smallmouth Bass Sampling from the Yellowstone River, Montana 2016-2019
Field data of age-0 smallmouth bass (Micropterus dolomieu) estimated age, lengths and weights, distribution from field sampling, and results from environmental DNA surveys from the Yellowstone River in Montana. Data were used in conjunction with existing stream temperature data from USGS gages to evaluate if temperature is related to age-0 size at the onset of winter.
Spectral reflectance measurements of radiometric calibration panels for UAS image calibration
Calibration panels are used as reference materials with known reflectance characteristics to convert remote sensing image pixel values to scientific units such as reflectance. At the time of purchase, the panel vendor typically provides the customer with reflectance data for the panel. The vendor-provided spectral data as a reference for each panel’s reflectance values at the time of purchase. Ove
Compilation of geologic slip rate constraints used in 1996-2014 U.S. National Seismic Hazard Models (ver. 2.0, February 2022)
A key input for probabilistic seismic hazard analysis (PSHA) is geologic slip rate data. Here, we compile all geologic slip rates that are reportedly used in U.S. National Seismic Hazard Map (NSHM) releases from 1996, 2002, 2007, 2008, and 2014. Although a new NSHM was released in 2018, no changes were made in geologic slip rate data used. The geologic slip rates are collated from existing NSHM re
