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.

Enhanced Terrain Imagery of the Wellsboro 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution Enhanced Terrain Imagery of the Wellsboro 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 Wellsboro 30 x 60 minute quadrangle in Pennsylvania. 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 2019 and 2020. The data were processed using geographic...
In-stream and laboratory fDOM data from wildfire affected streams of the western United States, 2021-22 In-stream and laboratory fDOM data from wildfire affected streams of the western United States, 2021-22
After wildfires occurred in the western United States during 2020, in-stream water quality monitors and automatic samplers were deployed in four burned watersheds and one unburned watershed. In-stream water temperature, turbidity, and fluorescent dissolved organic matter (fDOM) were measured at high frequency, and the fDOM data were corrected for temperature and turbidity effects...
Oak Savanna Ground Layer Plant Diversity Across the Lower Great Lakes Oak Savanna Ground Layer Plant Diversity Across the Lower Great Lakes
This dataset is part of a study to examine the condition of oak savannas in the southern Great Lakes (Illinois, Indiana, Michigan, Ohio and Wisconsin) and to understand how management has contributed to ground layer restoration. If not destroyed, oak savanna have experienced fire suppression, causing decline in these fire dependent systems. Management includes prescribed burning, shrub...
Preserving Tree-Ring Datasets for Climate and Hazard Research and Understanding Societal Impacts: Carrara Career Samples Preserving Tree-Ring Datasets for Climate and Hazard Research and Understanding Societal Impacts: Carrara Career Samples
Dendrochronological collections during the career of USGS emeritus, Paul Carrara: Douglas-fir (Pseudotsuga menziesii), Black cottonwood (Populus trichocarpa), Spruce (Picea), Shore pine (Pinus contorta contorta), Willow (Salix), Bristlecone pine (Pinus aristate), Engelmann spruce (Picea engelmannii), Aspen (Populus tremuloides), and Limber pine (Pinus flexilis) collections from western...
Data Support for a Statistical Perspective on the Petrologic Utility of Polyphase Groundmass Compositions Inferred Via Defocused Beam Electron Probe Microanalysis Data Support for a Statistical Perspective on the Petrologic Utility of Polyphase Groundmass Compositions Inferred Via Defocused Beam Electron Probe Microanalysis
This dataset contains major and trace element compositions for a sample of basalt recovered from Rangitoto Island, New Zealand. Both bulk rock and microanalytical observations are made and presented. Electron probe microanalysis (EPMA) results detail the compositions of individual phases within the basalt including olivine, clinopyroxene, plagioclase feldspar, glass, and polyphase...
Characterizing projected future (2056-95) droughts in south Florida based on the Multivariate Adaptive Constructed Analogs (MACA) downscaled climate dataset from the Coupled Model Intercomparison Project Phase 5 Characterizing projected future (2056-95) droughts in south Florida based on the Multivariate Adaptive Constructed Analogs (MACA) downscaled climate dataset from the Coupled Model Intercomparison Project Phase 5
The South Florida Water Management District (SFWMD) and the U.S. Geological Survey (USGS) have evaluated projections of future (2056-95) droughts for south Florida based on climate model output from the Multivariate Adaptive Constructed Analogs (MACA) downscaled climate dataset from the Coupled Model Intercomparison Project Phase 5 (CMIP5). The emission scenarios evaluated include...
