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.

Specific conductance and fiber-optic distributed temperature sensing data collected at Operable Unit 2, North Chevalier Field Disposal Area (Site 11), Naval Air Station Pensacola, Florida, 2018-2022 Specific conductance and fiber-optic distributed temperature sensing data collected at Operable Unit 2, North Chevalier Field Disposal Area (Site 11), Naval Air Station Pensacola, Florida, 2018-2022
This data release consists of two datasets, each accessible in its own child page, collected at the North Chevalier Field Disposal Area (Site 11) at Naval Air Station Pensacola in Florida. Site 11 is adjacent to Bayou Grande, which empties into Pensacola Bay. The first dataset consists of fiber-optic distributed temperature sensing data collected from March 13-March 16, 2018. The second...
Toxic Elements Found in Keratin, Liver, and Kidney of Ill, Dying, and Freshly Dead Agassiz’s Desert Tortoises (Gopherus agassizii) from the Mojave and Colorado Deserts of California between 1993 and 2000 Toxic Elements Found in Keratin, Liver, and Kidney of Ill, Dying, and Freshly Dead Agassiz’s Desert Tortoises (Gopherus agassizii) from the Mojave and Colorado Deserts of California between 1993 and 2000
The single database is in an excel file and includes data on elements occurring in keratin, liver, and kidneys of 46 Agassiz’s desert tortoises salvaged from the Mojave and Colorado deserts of California between 1993 and 2000.
Modeled habitat suitability for Erigeron rhizomatus (Zuni fleabane) Modeled habitat suitability for Erigeron rhizomatus (Zuni fleabane)
This raster presents the final outputs from a VisTrails/SAHM workflow to model the potential distribution of Zuni fleabane (Erigeron rhizomatus) in northwestern New Mexico. These models utilized field data of spatially thinned occurrence locations and random background locations. We included a suite of predictors related to soils, topography, vegetation cover, and geology. Details about...
Sentinel-2 ACOLITE-DSF Aquatic Reflectance for the Conterminous United States Sentinel-2 ACOLITE-DSF Aquatic Reflectance for the Conterminous United States
This dynamic data release presents an aquatic reflectance product with 20-meter spatial resolution derived from Sentinel-2 satellite imagery for the conterminous United States using the Atmospheric Correction for OLI “lite” (ACOLITE). Aquatic reflectance, noted Rhow in ACOLITE documentation, is defined here as unitless water-leaving radiance reflectance and represents the ratio of water...
Radiometric Ages and Descriptive Data for Late Holocene Acropora spp. Corals From Dry Tortugas National Park Radiometric Ages and Descriptive Data for Late Holocene Acropora spp. Corals From Dry Tortugas National Park
This data release compiles radiometric data, photographs, and descriptive collection information (location, elevation, etc.) for late Holocene sub-fossil Acropora palmata and A. cervicornis coral samples collected from the coral reefs of Dry Tortugas National Park, Florida (DRTO) from 2015 to 2023. The samples were collected under scientific research permits from the U.S. National Park...
Conterminous U.S. data used for modeling non-native vascular plant first records 1780-2022 Conterminous U.S. data used for modeling non-native vascular plant first records 1780-2022
This dataset was used for modeling the spatial distribution of first records of non-native plants in the conterminous U.S. The input dataset (alldata_input_frdm.csv) contains 4,763 rows of data, representing 1,538 counties in the contiguous U.S., 25 decades, and 3,389 first records of invasive terrestrial plant species (Williams et al., 2024) found in the US-RIIS list (Simpson et al...
