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.

Spectral reflectance measurements of standard reference materials in laboratory setting using an Analytical Spectral Devices (ASD) FieldSpec® 4 Hi-Res and Ocean Optics OCEAN-HDX-VIS-NIR® (HDX), suitable for comparison to other spectroradiometer measuremen Spectral reflectance measurements of standard reference materials in laboratory setting using an Analytical Spectral Devices (ASD) FieldSpec® 4 Hi-Res and Ocean Optics OCEAN-HDX-VIS-NIR® (HDX), suitable for comparison to other spectroradiometer measuremen
Two spectroradiometers, a Malvern Panalytical Analytical Spectral Devices FieldSpec® 4 Hi-Res (hereafter referred to as ASD spectrometer) and a high sensitivity spectrometer, OCEAN-HDX-VIS-NIR®, from Ocean Optics (hereafter referred to as HDX) were used to collect reflectance measurements of materials in a controlled indoor setting at the USGS Spectroscopy Lab in Denver, Colorado on July...
Data for Brown Pelican Bayesian Network Model Data for Brown Pelican Bayesian Network Model
This U.S. Geological Survey (USGS) data release represents data for the creation of a spatially explicit Bayesian network model that predicts Brown Pelican nests on islands across the U.S. portion of the Gulf of Mexico. Well-targeted management plans are needed to achieve Brown Pelican population objectives (number of breeding pairs) because conservation and restoration opportunities are...
Metrics to Characterizing Periods of Anomalously Low Water Storage for Selected Reservoirs in the Conterminous U.S. from 1981 to 2020 Metrics to Characterizing Periods of Anomalously Low Water Storage for Selected Reservoirs in the Conterminous U.S. from 1981 to 2020
This metadata record describes a series of tabular datasets containing metrics used to characterize periods of anomalously low storage for select large reservoirs across the Conterminous United States for the climate years (April 1 – March 31) from 1981 to 2020. These data support the associated Simeone and others (2024) publication. The reservoirs in this dataset are those included in...
Bathymetry and Water-Quality Data of Surface Water Bodies in Cook County, Illinois, 2024 (ver. 2.0, February 2025) Bathymetry and Water-Quality Data of Surface Water Bodies in Cook County, Illinois, 2024 (ver. 2.0, February 2025)
In 2024, the U.S. Geological Survey (USGS), in collaboration with the Cook County Bureau of Technology (BOT), carried out comprehensive hydrographic and water-quality surveys, and activity and disturbance assessments of 44 total water bodies encompassing lakes and rivers within Cook County, Illinois. These surveys and assessments describe the bathymetry, water-quality conditions, and on...
Apical outcomes associated with exposure of Japanese quail (Coturnix japonica) to hexabromocyclododecane flame retardant: F0 and F1 generation Apical outcomes associated with exposure of Japanese quail (Coturnix japonica) to hexabromocyclododecane flame retardant: F0 and F1 generation
This data set was generated from a study investigating potential effects of hexabromocyclododiene (HBCD) exposure across multiple generations of Japanese quail, (Coturnix japonica, JQ). Exposures ranged from dietary for the initial generation (F0), to dietary and possible maternal deposition) for the second generation (F1), and possible maternal deposition only for the third generation...
AquaMatch Chlorophyll a Data from Water Quality Portal: ~1970-2024 AquaMatch Chlorophyll a Data from Water Quality Portal: ~1970-2024
This dataset, “AquaMatch Chlorophyll a Data from Water Quality Portal ~1970-2024”, is a component of a forthcoming update to AquaSat (Ross et al., 2019), AquaSat version 2 (“v2”). The overarching purpose of AquaSat V2 is to emphasize the individual parts of the AquaSat pipeline that make-up the matchups between satellite and in-situ measurements.
