Data

These data were collected to investigate how well wind speed and direction can be measured using a miniature sonic anemometer mounted in a joust configuration on a small uncrewed aircraft system (sUAS). Test flights occurred at a bog within Interior Alaska that was instrumented with an eddy covariance flux tower. Part of the tower's instrumentation was a highly accurate sonic anemometer...

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...

In July 1992 soils were sampled from six dune fields in the northern Lower Peninsula of Michigan near Wilderness State Park, about 10 miles southwest of Mackinaw City. The dune fields represent a soil chronosequence, where all soil forming factors except time are held constant (climate, organisms, relief, and parent material). These sandy lake terrace soils are Entisols and Spodosols...

Early studies of soil formation highlighted several key factors that together determine the degree of soil pedogenesis, which include climate, organisms (including vegetation), topography, and parent material (Jenny H.; 1941; Factors of Soil Formation, a System of Quantitative Pedology; https://doi.org/10.2134/agronj1941.00021962003300090016x). A soil chronosequence is defined as a...

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 Biscayne National Park. For information on the digital elevation model (DEM) source used to develop these datasets refer to the corresponding spatial metadata file (Danielson and others...

Samples of silicified wood remnants from 8 trees were collected under research permit YELL-SCI-8030 on June 17, 2023, and on September 19, 2023 adjacent to Artemisia Geyser in the Upper Geyser Basin of Yellowstone National Park. Samples were collected for radiocarbon (14C) dating of the wood to determine when the trees grew. Trees do not grow on active geyser mounds (Hurwitz and others...

Data consist of census counts of Pliocene benthic foraminifera from the Yorktown Formation at Pipsico Boy Scout Camp, Spring Grove, Virginia. Data consist of grain-size distribution by weight in grams of samples collected from the Yorktown Formation exposed in outcrop along the James River at Pipsico Boy Scout Camp, Spring Grove, Virginia. In total, counts of individuals from 15 samples...

Here we provide data used to report on changes in tidal marsh elevation at the Blackwater National Wildlife Refuge (NWR), located in Dorchester, Maryland, USA. This dataset includes Surface Elevation Table (SET) measurements taken from 40 SET platforms distributed across the refuge. At each platform location annual measurements of wetland surface elevation were made from 20010-2013.
