Data release for: Evaluating k-nearest neighbor (kNN) imputation models for species-level aboveground forest biomass mapping in northeast China Data release for: Evaluating k-nearest neighbor (kNN) imputation models for species-level aboveground forest biomass mapping in northeast China
Quantifying spatially explicit or pixel-level aboveground forest biomass (AFB) across large regions is critical for measuring forest carbon sequestration capacity, assessing forest carbon balance, and revealing changes in the structure and function of forest ecosystems. When AFB is measured at the species level using widely available remote sensing data, regional changes in forest...
Great Dismal Swamp field measurements for aboveground and belowground biomass Great Dismal Swamp field measurements for aboveground and belowground biomass
Plot-level field data were collected in the summer of 2014 to estimate aboveground and belowground biomass in the Great Dismal Swamp National Wildlife Refuge and Dismal Swamp State Park in North Carolina and Virginia. Data were collected at 85 plots. The location of the center of each plot was recorded with a Trimble ProXH global positioning system (GPS) and differentially corrected...
Batch sorption data, respired CO2, extractable DOC, and Raman spectra collected from an incubation with microbial necromass on feldspar or amorphous aluminum hydroxide Batch sorption data, respired CO2, extractable DOC, and Raman spectra collected from an incubation with microbial necromass on feldspar or amorphous aluminum hydroxide
These datasets are from an incubation experiment with a combination of two minerals (feldspar or amorphous aluminum hydroxide), one living species of bacteria (Escherichia coli), and one added form of C (Arthrobacter crystallopoietes necromass). We characterized the sorptive properties of the minerals with batch sorption experiments using four low molecular weight C substrates (glucose...
U-series isotope data used to date a 130,000-year-old archaeological site in southern California, U.S.A. U-series isotope data used to date a 130,000-year-old archaeological site in southern California, U.S.A.
Data release for "A 130,000-year-old archaeological site in southern California, U.S.A", published as a Letter to Nature. Includes sample information, U-Th isotope compositions, calculated U-series (230Th/U) ages and initial 234U/238U activity ratios, for mastodon bones from the Cerutti Mastodon site in National City, CA. Formatted data tables can be found in the Supplementary...
Data Rease for "Isotopic constraints on middle Pleistocene cave evolution, paleohydrologic flow, and environmental conditions from Fitton Cave speleothems, Buffalo National River, Arkansas" Data Rease for "Isotopic constraints on middle Pleistocene cave evolution, paleohydrologic flow, and environmental conditions from Fitton Cave speleothems, Buffalo National River, Arkansas"
Data release for "Isotopic constraints on middle Pleistocene cave evolution, paleohydrologic flow, and environmental conditions from Fitton Cave speleothems, Buffalo National River, Arkansas". Extended abstract for the 2017 Karst Interest Group meeting. Includes sample information, U-Th isotope compositions, calculated U-series (230Th/U) ages and initial 234U/238U activity ratios, Sr...
Data Release for Phosphorous speciation and solubility in aeolian dust deposited in the interior American West Data Release for Phosphorous speciation and solubility in aeolian dust deposited in the interior American West
This release contains avaialable particle-size and mineralogic data as well as latitude and longitude information for dust samples collected from snow at high elevation sites in the Colorado Rocky Mountains and from dust source areas on the Colorado Plateau.
Data release for application of a luminescence-based sediment transport model Data release for application of a luminescence-based sediment transport model
This data release contains luminescence data from the manuscript "Application of a luminescence-based sediment transport model" by Gray et al. It contains data from the luminescence measurements and experiments in the paper.
Data release for Applying the Community Ice Sheet Model to evaluate PMIP3 LGM climatologies over the North American ice sheets Data release for Applying the Community Ice Sheet Model to evaluate PMIP3 LGM climatologies over the North American ice sheets
The data release consists of a single NetCDF file with results from a suite of ice sheet model simulations. We ran with Community Ice Sheet Model (CISM2) with input from models used in the Palaeoclimate Modelling Intercomparison 3 (PMIP3). The NetCDF file contains output from model year 5000 for a limited number of variables to keep the file size reasonably small. This subset of...
Data release of Three-Dimensional Hydrogeologic Framework Model of the Petaluma Valley Watershed, Sonoma County, California Data release of Three-Dimensional Hydrogeologic Framework Model of the Petaluma Valley Watershed, Sonoma County, California
This digital dataset was created as part of a U.S. Geological Survey study, done in cooperation with the Sonoma County Water Agency and the City of Petaluma, to be used as the digital hydrogeologic input data for numerical simulation of the groundwater system of the Petaluma Valley Watershed, Sonoma County, California. Elevation, thickness, and extent of the hydrostratigraphic units...
Data release for a paleomagnetic age estimate for the drainage of ancient Lake Alamosa, San Luis Valley, southwestern Colorado Data release for a paleomagnetic age estimate for the drainage of ancient Lake Alamosa, San Luis Valley, southwestern Colorado
Samples, sample depths, paleomagnetism, and magnetic susceptibility parameters are recorded for BP-3-USGS well, San Luis Valley, Southwestern Colorado
Data Release for Geologic Map of the Pagosa Springs 7.5-minute quadrangle, Archuleta County, Colorado Data Release for Geologic Map of the Pagosa Springs 7.5-minute quadrangle, Archuleta County, Colorado
The Pagosa Springs geologic map is of the 7.5-minute quadrangle of the same name. It is located in southwestern Colorado, USA and shows the town of Pagosa Springs. The mapped area is southwest of the San Juan volcanic mountains (Oligocene) and north of the San Juan Basin. All bedrock units exposed in the map area are Upper Cretaceous in age except a minor canyon outcrop of Upper Jurassic...
Data release for estimating soil respiration in a subalpine landscape using point, terrain, climate and greenness data Data release for estimating soil respiration in a subalpine landscape using point, terrain, climate and greenness data
Landscape carbon (C) flux estimates are necessary for assessing the ability of terrestrial ecosystems to buffer further increases in anthropogenic carbon dioxide (CO2) emissions. Advances in remote sensing have allowed for coarse-scale estimates of gross primary productivity (GPP) (e.g., MODIS 17), yet efforts to assess spatial patterns in respiration lag behind those of GPP. Here, we...
