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...
Long-term precipitation reduction experiment in the Colorado Plateau - Survival and mortality data from 2010 to 2018 Long-term precipitation reduction experiment in the Colorado Plateau - Survival and mortality data from 2010 to 2018
From 2011-2018 USGS biologists recorded vegetation and biological soil crust (BSC) cover by species and tracked survival of tagged individual plants (388 in total) across 40 locations where paired experimental plots had been installed in 2010. Plant cover was visually estimated using four 75 x 100 cm survey frames. Each site contained a two plots measuring 1.5 by 2.0 meteres: a control...
Data and estimates for wet deposition and streamwater solute fluxes at Panola Mountain Research Watershed, Stockbridge, Ga., water years 1986-2016 Data and estimates for wet deposition and streamwater solute fluxes at Panola Mountain Research Watershed, Stockbridge, Ga., water years 1986-2016
This dataset contains the data and results of an analysis estimating wet deposition and streamwater solute fluxes at Panola Mountain Research Watershed (PMRW), Panola Mountain State Park, Stockbridge, Georgia for water years 1986-2016. The PMRW is a small (41 ha), relatively undisturbed, forested headwater catchment in the Piedmont Province of Southeastern United States. This data...
Paleohydrologic reconstructions of water-year streamflow for 31 stream gaging sites in the Missouri River Basin with complete data for 1685 through 1977 Paleohydrologic reconstructions of water-year streamflow for 31 stream gaging sites in the Missouri River Basin with complete data for 1685 through 1977
Tree-ring reconstructions of water-year (Oct 1 through Sep 30th) flow for 31 gaging sites in Missouri River basin, with complete data for 1685 through 1977 (n = 293 water years). The complete 105 tree-ring reconstructions of streamflow used in the Nature Scientific Reports paper were obtained from various sources; 74 flow reconstructions were obtained from the web resource, TreeFlow...
Modeling barrier island habitats using landscape position information for Dauphin Island, Alabama Modeling barrier island habitats using landscape position information for Dauphin Island, Alabama
Barrier islands provide important ecosystem services, including storm protection and erosion control to the mainland, habitat for fish and wildlife, and tourism (Barbier and others, 2011; Feagin and others, 2010). These islands tend to be dynamic due to their location along the estuarine-marine interface. Besides gradual changes caused by constant forces, such as currents and tides...
Data on soil denitrification potential and physico-chemical characteristics of tidal freshwater forested wetlands in Virginia. Data on soil denitrification potential and physico-chemical characteristics of tidal freshwater forested wetlands in Virginia.
Denitrification measurements and ecosystem attributes in hummock-hollow microtopography of tidal freshwater forested wetlands along longitudinal riverine positions (upper, middle, and lower tidal river sites, and nearby upstream nontidal forested floodplains) of the adjoining Pamunkey and Mattaponi Rivers, Virginia.
Predictive maps of 2D and 3D surface soil properties and associated uncertainty for the Upper Colorado River Basin, USA Predictive maps of 2D and 3D surface soil properties and associated uncertainty for the Upper Colorado River Basin, USA
The raster datasets in this data release are maps of soil surface properties that were used in analyzing different approaches for digital soil mapping. They include maps of soil pH, electrical conductivity, soil organic matter, and soil summed fine and very fine sand contents that were created using both 2D and 3D modeling strategies. For each property a map was created using both 2D and...
Glacier-Adjacent Weather Station Data Glacier-Adjacent Weather Station Data
Measurements of meteorological data have been collected since the beginning of the USGS Benchmark Glacier Program adjacent to glaciers to support related science. This portion of the data collection includes select weather data that has received basic quality control and assurance. Data is released at three different levels of processing, level 0, 1 and 2. Level 0 data contains compiled...
Data release for Applying the Community Ice Sheet Model to evaluate PMIP3 LGM climatologies over the North American ice sheets (ver. 2.0, February 2019) Data release for Applying the Community Ice Sheet Model to evaluate PMIP3 LGM climatologies over the North American ice sheets (ver. 2.0, February 2019)
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...
Using relative topography and elevation uncertainty to delineate dune habitat on barrier islands Using relative topography and elevation uncertainty to delineate dune habitat on barrier islands
Dunes with a high relative topography can often be easily distinguished in high-resolution lidar-based digital elevation models (DEMs). Thus, researchers have begun using relative topography metrics, such as the topographic position index (TPI; Weiss, 2001), to identify ridges and upper slopes for extracting dunes from lidar-based DEMs (Wernette et al., 2016; Halls et al. 2018). DEMs are...
Microclimate influences mangrove freeze damage: Implications for range expansion in response to changing macroclimate Microclimate influences mangrove freeze damage: Implications for range expansion in response to changing macroclimate
In this data release, we present data from three nights of chilling temperatures in 2015 (18th/19th January 2015; 18th/19th February 2015; 5th/6th March 2015) and from three nights of freezing temperatures in 2017/2018 (6th/7th January 2017; 1nd/2nd January 2018; 16th/17th January 2018). In the paper that accompanies this release, we synthesized hypotheses regarding the effects of...
33 high-resolution scenarios of land use and vegetation change in the Upper Missouri River Basin 33 high-resolution scenarios of land use and vegetation change in the Upper Missouri River Basin
A new version of USGS's FORE-SCE model was used to produce unprecedented landscape projections for the Upper Missouri River Basin region of the northern Great Plains. The projections are characterized by 1) high spatial resolution (30-meter cells), 2) high thematic resolution (29 land use and land cover classes), 3) broad spatial extent (covering approximately 516,000 square kilometers)...
