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.

High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, Utah from 2020-2023 High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, Utah from 2020-2023
The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, UT. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et...
Species Distribution Models for Pectis imberbis, a Rare Plant Species in Southeastern Arizona Species Distribution Models for Pectis imberbis, a Rare Plant Species in Southeastern Arizona
Species distribution models (SDMs) can be an important tool in rare species conservation. Specifically, SDMs have been used to location previously unknown populations and identify sites for reintroduction or translocation. With these goals in mind, we applied SDM to a recently listed plant species, Pectis imberbis, which is found in the Madrean Archipelago region of southern Arizona, USA...
Larval Fish Abundance, Identification, and Auxiliary Data from the Great Lakes and Their Connecting Waters, 2006-2022 Larval Fish Abundance, Identification, and Auxiliary Data from the Great Lakes and Their Connecting Waters, 2006-2022
This dataset contains data collected on various vessel operations on the Great Lakes and their connecting channels, primarily the St. Clair River, St. Marys River, Lake St. Clair, Detroit River, and Lake Erie, although other locations have been sampled and included in this dataset. This dataset contains the field variables, environmental conditions, larval catches (numbers), larval fish
Fluorite Samples from the Western United States - The Ronald G. Worl Collection Fluorite Samples from the Western United States - The Ronald G. Worl Collection
This dataset describes fluorite- and manganese-bearing samples collected and compiled by USGS Commodity Specialist, Ronald G. Worl during the 1970's. The dataset corresponds to a physical collection of fluorite- and manganese-bearing samples re-established under the National Geological and Geophysical Data Preservation Program. The collection includes samples that were used in the...
Enhanced Terrain Imagery of the Kingwood 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution Enhanced Terrain Imagery of the Kingwood 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Kingwood 30 x 60 minute quadrangle in West Virginia and Maryland. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2020 and 2023. The data were processed using...
Conservation Genetics and Genomics of the Narrowly Endemic Island Marble Butterfly: Assessing Population Structure, Facilitating Supportive Breeding, and Identifying Adaptive Potential Conservation Genetics and Genomics of the Narrowly Endemic Island Marble Butterfly: Assessing Population Structure, Facilitating Supportive Breeding, and Identifying Adaptive Potential
The purpose of this study was to collect and analyze non-invasive DNA specimens from the endangered island marble butterfly (Euchloe ausonides insulanus) to assess population structure, identify adaptive potential, facilitate captive propagation, and support translocation planning. We used DNA extracted from meconium, exuviae, and natural mortalities to generate and test thirteen new
