Mercury Concentrations in Burmese Pythons Across the Greater Everglades Region in Florida from 2001 to 2022 Mercury Concentrations in Burmese Pythons Across the Greater Everglades Region in Florida from 2001 to 2022
Burmese Pythons are an invasive reptilian species that has spread throughout southern Florida. Mercury (Hg) concentration in python tail muscles were examined across the Great Everglades region in two periods, 2001 - 2011 and 2014 - 2019. The python samples collected spanned a large range of habitats, including wetland, forested, and urban areas. In 2022 tissues from the offspring six...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources in the provinces of Mexico, Belize, and Guatemala. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil...
Oceanographic and hydrographic monitoring data of a shallow-water placement of dredged sediment in South San Francisco Bay, California, 2023-2025 Oceanographic and hydrographic monitoring data of a shallow-water placement of dredged sediment in South San Francisco Bay, California, 2023-2025
The U.S. Geological Survey Pacific Coastal and Marine Science Center collected oceanographic and hydrographic monitoring data for a pilot project to place dredged sediment in bay shallows to nourish marshes conducted by the US Army Corps of Engineers, San Francisco District. Dredged material was placed in the shallows of South San Francisco Bay during December 2023. Monitoring spanned...
Daily predictions of water temperature for streams across the contiguous United States (1979-2021) Daily predictions of water temperature for streams across the contiguous United States (1979-2021)
This model application data release provides the data processing and model code used to generate predictions of daily stream water temperature across the contiguous United States from 1979-2021. We used a recurrent graph convolutional network (RGCN) algorithm to make daily stream temperature predictions. Stream water temperature observations, along with forcing data consisting of daily
Pre- and post-fire modeled vegetation structure products for the Caldor, Cedar Creek, Dixie, KNP, and Muckamuck fires Pre- and post-fire modeled vegetation structure products for the Caldor, Cedar Creek, Dixie, KNP, and Muckamuck fires
Post-fire vegetation status and condition have multiple implications. They are indicative of burn severity and the lasting impacts of fire the land; they also help inform post-fire debris flow modeling and related risk analyses, hydrology and water quality assessments, and vulnerability to invasive species. Monitoring vegetation recovery over time enables continuous re-evaluation of...
Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, UWD) from January 1 to June 30, 2025 Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, UWD) from January 1 to June 30, 2025
Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, UWD) from January 1 to June 30, 2025. These data were collected in 2025 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory.
3-Dimensional Point Clouds, Field Data, and Treelists from Three Montane Landscapes in New Mexico 3-Dimensional Point Clouds, Field Data, and Treelists from Three Montane Landscapes in New Mexico
These data include a collection of 3-dimensional (3D) point clouds from three New Mexico landscapes and associated field-collected validation data accompanying each scan. The data were collected in fall of 2022-2023 across three montane New Mexico landscapes - similar in climate but differing in disturbance histories. Landscapes include a intensely and repeatedly burned shrubfield, a...
Input and output data used to assess the effects of climate on the temporal variability in streamflow and total dissolved solids loads in the Upper Colorado River Basin, water years 1986-2021 Input and output data used to assess the effects of climate on the temporal variability in streamflow and total dissolved solids loads in the Upper Colorado River Basin, water years 1986-2021
This data release contains the input and output used to assess the potential effect of climate on streamflow and salinity (measured as total dissolved solids [TDS]) yields across the Upper Colorado River Basin from water years 1986 to 2021. This analysis included estimation of the spatiotemporal variability in mean annual climatic variables (air temperature, snow water equivalent...
Status and trends in stream temperature, salinity, flow, hydromorphology, and biological assemblages across the Chesapeake Bay Watershed Status and trends in stream temperature, salinity, flow, hydromorphology, and biological assemblages across the Chesapeake Bay Watershed
The Chesapeake Bay watershed is home to over 18.5 million people and continues to experience rapid population growth. With changes in population and land development, understanding current conditions of streams within the watershed (status), and changes in condition over time (trends) is important for assessing stream health. This data release contains the output files for results of...
Luminescence, charcoal abundance, and radiocarbon data for: Geochronologic data reveal late Pleistocene to Holocene debris-flow history and wildfire association within Whiskeytown National Recreation Area, Klamath Mountains, northern California Luminescence, charcoal abundance, and radiocarbon data for: Geochronologic data reveal late Pleistocene to Holocene debris-flow history and wildfire association within Whiskeytown National Recreation Area, Klamath Mountains, northern California
This report summarizes the dating results from sedimentary deposits sampled by the National Park Service and the U.S. Geological Survey and analyzed at the USGS Luminescence Geochronology Laboratory. Within this report, we detail the luminescence measurement, equivalent dose determination, and dating-related calculations. We recommend that this report be included as the supplementary...
Compilation of contaminant of emerging concern concentrations (1991 - 2021) and associated hazard scores for assessment of potential hazard to fish in the Great Lakes Basin Compilation of contaminant of emerging concern concentrations (1991 - 2021) and associated hazard scores for assessment of potential hazard to fish in the Great Lakes Basin
This data release contains concentration and hazard score data for 16 contaminants of emerging concern (CECs) collected from surface waters throughout the Great Lakes basin. Concentration data were compiled from various online, published, or internal sources. Original data represent work conducted by federal, state, and local entities over a span of 30 years (1991 - 2021). Hazard scores...
Northern mockingbird ileal virome variation in Texas Northern mockingbird ileal virome variation in Texas
A few studies have focused on avian gut virome variation in response to environmental stressors, but none have assessed virome in relation to chemically intensive crops, the production of which effects various aspects of avian health and fitness, and deleteriously alters available food resources. In this study we used shotgun metatranscriptomics (2 x 150bp; Illumina HiSeq 4000 with...
