Data

These data were compiled to assess time series data of aeolian sediment collections across varying climates, vegetation cover, and land uses on the Colorado Plateau. The objectives of our study were to interpret aeolian erosion and deposition processes and measure horizontal sediment flux over the span of two decades amid rapidly changing climate conditions and multiple land use changes...

These files consist of scanned field notebooks from long-term research and monitoring conducted in the Loch Vale watershed, Rocky Mountain National Park from June 17, 1981, through September 19, 2023. There are 72 individual PDF files. They are accompanied by a spreadsheet that serves as a pointer to the contents of each notebook, including the range of years in each, start and end dates...

Surface Elevation Tables and Marker Horizon (collectively SET-MH) datasets provide a unique opportunity to evaluate tidal marsh accretion rates compared with current and projected sea-level rise. SET is a tool that allows for accurate and repeatable measurements of marsh elevation, while Marker Horizon allows for the measurement of sediment that has deposited on top of the feldspar...

This foraminiferal census data was originally produced by USGS research Geologist Thomas G. Gibson in the 1960s through the early 2000s. The census data here documents evidence of foraminifer populations found in sediment samples extracted from four cores from the Atlantic Coastal Plain and the Gulf Coastal Plain. These samples represent Pliocene, Middle- Miocene and Paleocene-Eocene...

Data include diversity measures (number of individuals, number of species, Shannon diversity, Evenness and Dominance) for 2,315 samples of Pliocene age.

Planktic foraminiferal species distributions in the modern ocean track environmental features like latitudinal temperature gradients. Species shift their distributions as the marine environment changes, providing an analog for past behavior. Stationarity of species’ ecological tolerances is a first-order assumption of all paleoenvironmental reconstructions based upon modern analog...

Monosaccharide anhydrides (MAs), or anhydrosugars which include levoglucosan, mannosan, and galactosan are combustion products of cellulose and hemicellulose that are used as biomass burning tracers. These fire biomarkers are incorporated into smoke plumes, transported through the atmosphere, and return to the surface through wet and dry deposition that can be archived in ice cores. Here...

These data are the geochemical (from X-ray fluorescence spectrometry), grain size, lithological (loss on ignition), diatom assemblages (taxa counts), bathymetric, and radioactive isotopes (210-Pb, 137Cs) from sediments from Wildcat Lake, Point Reyes National Seashore, California, USA starting in 2021. Taken together, they provide evidence for extreme precipitation events linked to...

Culebra Range of the Sangre de Cristo Mountains, Colorado. Sample Collection: Ponderosa pine (Pinus ponderosa), Douglas-fir (Pseudotsuga menziesii), Bristlecone pine (Pinus aristate), and Limber pine (Pinus flexilis) living in lower and upper montane slopes of the Culebra Range (~Latitude 37˚N, ~Longitude -105˚W WGS84). The Fire-Climate-Human NGGDPP archive collection was obtained in two...

This dataset provides topographic indices derived from 1 m resolution DEMs for sequoia groves in both Sequoia-Kings Canyon and Yosemite National Parks. All mapped sequoia groves in Sequoia-Kings Canyon National Park and two groves from Yosemite National Park, Merced and Mariposa, are included. For each grove, we calculated aspect, slope, the stream network, height above nearest drainage...

This dataset includes elevation-based probability and depth statistics for estimating inundation under various sea-level rise and high tide flooding scenarios in and around the National Park Service’s San Juan National Historic Site. These datasets were developed using 1-m digital elevation model (DEM) from the 3D Elevation program. This data release includes results from analyses of two...

This dataset includes elevation-based probability and depth statistics for estimating inundation under various sea-level rise and high tide flooding scenarios in and around the National Park Service’s Dry Tortugas National Park. These datasets were developed using digital elevation model (DEM) from National Oceanic and Atmospheric Administration (NOAA). This data release includes results...
