Dynamic Surface Water Extent (DSWE) annual proportions of total surface water processed to the continental US Analysis Ready Data (ARD) tile scheme (https://landsat.usgs.gov/ard_tile) in Sarbanes and Jones 2025 are here resampled to the 20 m Sentinel-2 satellite grid using bilinear interpolation with a 3 by 3 pixel moving window. The resulting 973 tiles, with values ranging from 0 to 100...

Between 1900 and 1932, a copper (Cu) mine operated near Gay, Michigan, along the shore of Lake Superior, discharged approximately 22.8 million metric tons of waste material known as ‘stamp sands’ (SS) to a nearby beach. This pile of SS has migrated via wind and rain along the beaches in northern Grand Traverse Bay and into Buffalo Reef, an important spawning area for Lake Trout and Lake...

Dataset contains measured concentrations of PFAS analytes and limits of detection/quantification for 37 total samples. There are 82 total PFAS analytes (7 non-extracted internal standards, 24 extracted internal standards, and 51 target native analytes) and each individual sample has been quantified for all 82 of these compounds. Samples are extracts of plant tissues from three sources...

As the Arctic physical environment undergoes rapid change, permafrost conditions also are shifting. Thawing of ice-rich permafrost can cause terrain instability and compromise infrastructure as the permafrost excess ice content (EIC) melts – EIC refers to the volume of ground ice that exceeds the soil’s pore space when thawed. This dataset provides EIC depth measurements from 38...

These data were compiled to evaluate the impact of a utility-scale solar energy (Gemini Solar + Storage) development on ecosystem function in the Mojave Desert. Objectives of our study were to identify the short-term effects of construction on soils and vegetation across plant communities and soil types. These data represent a before-after control-impact study to evaluate the effects of...

This dataset details mercury (Hg) concentrations and carbon, nitrogen, and sulfur isotopes for Black and White tegus (Salvator merianae) collected in and around Everglades National Park between 2022 and 2024. Tegus (n = 115) were collected from 54 sites. Mercury in tegu muscle tissue ranged from 4.1 to 1200 ng g-1. Additional matrices such as livers and blood were measured on a subset of...

This dataset describes mercury (Hg) concentrations and methylation rate potentials that were measured in Lake Mendota, Wisconsin, US in 2020 and 2021. This work is a collaboration between the University of Wisconsin, University of California-Davis, and the U.S. Geological Survey. Samples were collected to examine the linkages between Hg methylation, biogeochemical conditions, and...

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 dataset presents mercury (Hg) and methylmercury (MeHg) concentration data in waters (surface river water and community drinking water), biota, plant, and sediments that were collected across eight communities along the Pra and Ankobra Rivers in Western Ghana. Water and sediment samples were collected in October 2024 from eight rivers along the Ankobra and Pra Rivers, two rivers...

This data release is an extension of a previous data release (https://doi.org/10.5066/P971S7IV) that expands the collected data to include tissue mercury concentrations for adult aquatic insects emerging from wadable wetlands in cropland and grassland landscapes of the Prairie Pothole region (n = 15 wetlands in 2016). These data were collected at the same time as the other data (analyzed...

This work integrated multiple topographic and bathymetric data sources to generate a merged topobathymetric map of Glacier Bay, Alaska (AK) and vicinity, including Icy Strait and parts of Lynn Canal. Earlier topobathymetric sources covering the Glacier Bay region were originally developed by the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental...

Data from environmental DNA (eDNA) samples filtered from seawater collected in the Gulf of America during a research expedition on the R/V Nancy Foster in August 2022. Samples were collected at depths throughout the water column using Niskins mounted to rosettes on Connectivity-Temperature-Depth instruments (CTDs) or Niskins mounted to remote operated vehicles (ROVs). Each eDNA sample...
