Geospatial datasets related to 6PPD-quinone, a compound intended to increase the life span of tires, were acquired and integrated into a relative heat index framework across the conterminous United States. 6PPD-quinone is known to be the cause of Coho Salmon kills following storm events, and more is being learned about the impacts it may have on other species. Sources and influential...

Gravity data were collected in 2022-2024 to assist in mapping surface and subsurface geology in the Medicine Bow Mountains of southern Wyoming. This data release provides principal facts for 738 new gravity stations that were acquired to supplement existing public gravity data coverage.

Planktic foraminifera are single-celled organisms playing a crucial role in marine food webs by cycling nutrients within ecosystems. They are heterotrophic protists feeding on phytoplankton, the primary producers in the ocean. In turn, planktic foraminifera serve as a food source for a range of marine animals including fish, crustaceans, other zooplankton, and larger predators. In this...

Contemporary climate change in Alaska has resulted in amplified rates of press and pulse disturbances that drive ecosystem change with significant consequences for socio-environmental systems. Despite the vulnerability of Arctic and boreal landscapes to change, little has been done to characterize landscape change and associated drivers across northern high-latitude ecosystems. Here we

This data release contains the model inputs, outputs, and source code (written in R) for a redeveloped PRObability of Streamflow PERmanence (PROSPER) model (version 2.1) that had previously been developed for the Pacific Northwest Region (PROSPER_PNW_2), and a raster data set which shows where influential predictor values were outside the range of calibration data. The PROSPER-PNW...

This dataset contains shapefiles that describe topographic long profiles of recent Martian gully flows recording various information about the flow and host gully. Each profile has some or all of the following: a profile of the active flow, a profile of the full gully, the location of the channel mouth, a profile recording different types of activity, a shapefile with locations of...

This dataset contains projected distributions for six non-native invasive tree and shrub species—autumn olive, bush honeysuckles, Callery pear, princess tree, privet, and tree-of-heaven—under four climate change scenarios, provided as ASCII (ASC) raster grids. Species distribution models were fitted using MaxEnt (Maximum Entropy) with occurrence data from EDDMapS and FIA and seven...

The goal of this project was to produce estimates of the change in three ecosystem services - water yield, sediment runoff, and reef productivity (or seafood benefits) - under climate change and three newly developed land cover scenarios. The developed land cover scenarios expanded upon the Hawaii Carbon Assessment by simulating future land cover scenarios. The resulting scenarios used...

Future sea-level rise poses a risk to mangrove forests. To better understand potential vulnerability, we developed a numerical model of soil elevation for mangrove forests. We used the model to generate projections of elevation and mangrove forest composition change under six sea-level rise scenarios from 2020 through 2150. We employed a data-driven modeling approach, utilizing new and...

Projections of vegetated area and vegetated plain elevation for salt marsh units within the Chesapeake Bay (CB) salt marsh complex are calculated using geospatial information for conceptual marsh units defined by Ackerman and others (2022) and Defne and others (2023). The projections are based on the UBMorph model, described in Ganju and others (2025), which estimates changes in areal...

Bed sediment samples were collected from the channels of 4 sites within northern San Francisco Bay, California, USA. The channels sampled were located in Corte Madera Bay, San Pablo Bay, Grizzly Bay and Suisun Bay. Sediment samples were collected with push cores, by subsampling a Gomex box corer. Cores, which ranged in length from 2 to 6 centimeters (cm), were sectioned by depth. The top...

Solid bitumen is widely used as a thermal proxy in source-rock reservoirs, yet its texture and presentation may be affected by varying environmental constraints during its formation, e.g., water concentration, mineral catalysis, or salinity. Herein we investigated the development of solid bitumen properties during artificial maturation using three diverse (lacustrine to marine) oil shale...
