Data
The climate history, land cover and land surface data developed by the Land Change Science Program in the USGS Ecosystems Mission Area is vital to various types of research and management applications, including assessing the impacts of climate change, evaluating ecosystem status and health, understanding spatial patterns of biodiversity, and informing land use planning.

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...
High Altitude Weather Station Data at USGS Benchmark Glaciers High Altitude Weather Station Data at USGS Benchmark Glaciers
Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. Additional measurements have been made on Lemon Creek Glacier, AK to compliment data collected by the Juneau Icefield...
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...
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)...
Data Release for The dependence of hydroclimate projections in snow-dominated regions of the western U.S. on the choice of statistically downscaled climate data Data Release for The dependence of hydroclimate projections in snow-dominated regions of the western U.S. on the choice of statistically downscaled climate data
Climate change information simulated by global climate models is downscaled using statistical methods to translate spatially course regional projections to finer resolutions needed by researchers and managers to assess local climate impacts. Several statistical downscaling methods have been developed over the past fifteen years, resulting in multiple datasets derived by different methods...
Data release for the Historical land use and land cover for assessing the northern Colorado Front Range urban landscape Data release for the Historical land use and land cover for assessing the northern Colorado Front Range urban landscape
The dataset was generated to describe historical land-use and land-cover (LULC)for the northern Colorado urban Front Range (which includes the cities of Boulder, Fort Collins, Greeley, and Denver) for an area covering approximately 1,023,660 hectares. The Front Range urban landscape is diverse and interspersed with highly productive agriculture as well as natural land cover types...
Aeolian mass flux, rangeland monitoring site, and unpaved road reach data Aeolian mass flux, rangeland monitoring site, and unpaved road reach data
These data were compiled for monitoring and analyzing the amount of windblown (aeolian) sediment at 100 cm height near Moab, UT. Big Springs Number Eight (BSNE) field aeolian passive sediment traps are summarized by location and time period in shapefiles. Shapefiles also include attributes used to analyze patterns in the aeolian transport. Three different BSNE shapefiles represent 1) a...
GDGT and Alkenone Flux in the Northern Gulf of Mexico GDGT and Alkenone Flux in the Northern Gulf of Mexico
This dataset is a weekly to bi-weekly resolution 4-year time series (2010-2014) of GDGT and alkenone flux in the northern Gulf of Mexico. The TEX86 and U indices are also included, which are sea surface temperature proxies based on the distribution of GDGTs and alkenones, respectively. For further information regarding data collection and/or processing methods refer to Richey and Tierney...
