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.

Geochemistry of Water Sources in the Wolverine Glacier Watershed, Alaska in 2016 and 2017 Geochemistry of Water Sources in the Wolverine Glacier Watershed, Alaska in 2016 and 2017
Glaciers are critical sources of water and solutes to downstream riverine and marine ecosystems. Samples were collected from surface streams, groundwater, rain, snow, and ice in the Wolverine Glacier basin and analyzed for a broad suite of geochemical constituents including common field parameters, major ions, stable isotopes of water, nutrients, metals, and dissolved organic carbon.
Assessing habitat change and migration of barrier islands Assessing habitat change and migration of barrier islands
A barrier island habitat prediction model was used to forecast barrier island habitats (for example, beach, dune, intertidal marsh, and woody vegetation) for Dauphin Island, Alabama, based on potential island configurations associated with a variety of restoration measures and varying future conditions of storminess and sea level (Enwright and others, 2020). This USGS data release...
Temperature, relative humidity and cloud immersion data for Luquillo Mountains, eastern Puerto Rico, 2014-2019 Temperature, relative humidity and cloud immersion data for Luquillo Mountains, eastern Puerto Rico, 2014-2019
Supplementary data for studies conducted in the Luquillo Experimental Forest (LEF), eastern Puerto Rico include measurements of temperature, relative humidity and cloud immersion at 30-minute resolution. Temperature and relative humidity were measured at five sites; two primary sites have records from March 2014 to June 2019; other sites have shorter records within that period. From...
Long-term annual aeolian dust deposition data from seven locations in southeastern Utah Long-term annual aeolian dust deposition data from seven locations in southeastern Utah
These data are annual aeolian dust deposition calculations from vertical deposition at seven locations near the vicinity of Moab, Utah covering the period from 1999 to 2020. Data were collected by the U.S. Geological Survey Geosciences and Environmental Change Science Center (Denver, Colorado) and Southwest Biological Science Center (Moab, Utah) to "monitor sediment characteristics at...
Fine root production in tidally influenced freshwater forested wetlands in South Carolina and Georgia, USA (2016-2017) Fine root production in tidally influenced freshwater forested wetlands in South Carolina and Georgia, USA (2016-2017)
This dataset includes fine root productivity data that were estimated via two techniques (serial coring and root in-growth bags) in tidal freshwater wetlands and adjacent oligohaline marshes in coastal South Carolina and Georgia from March 2016 through October 2017.
Cottonwood Lake Study Area - Invertebrate Counts - 1992 to 2019 Cottonwood Lake Study Area - Invertebrate Counts - 1992 to 2019
This dataset contains macroinvertebrate sampling data for the wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota.
Cottonwood Lake Study Area - Breeding Birds - 1992 to 2019 Cottonwood Lake Study Area - Breeding Birds - 1992 to 2019
This dataset contains the number of breeding pairs of bird species surveyed in all Cottonwood Lake Study Area wetlands.
Cottonwood Lake Study Area - Amphibians - 1992 to 2019 Cottonwood Lake Study Area - Amphibians - 1992 to 2019
This dataset contains the number of captured individuals recorded for each amphibian species surveyed in all wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota. While amphibians were the target of the surveys, reptiles (i.e., turtles, snakes) were also sometimes captured over the course of the surveys and are included in the data file.
Cottonwood Lake Study Area - Invertebrate Weights - 1992-2019 Cottonwood Lake Study Area - Invertebrate Weights - 1992-2019
This dataset contains macroinvertebrate sampling data (weights) for wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota.
Cottonwood Lake Study Area - Specific Conductance - 1992-2020 Cottonwood Lake Study Area - Specific Conductance - 1992-2020
This dataset contains the specific conductance values of water for all wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota.
Long-term soil carbon data and accretion from four marsh types in Mississippi River Delta in 2015 Long-term soil carbon data and accretion from four marsh types in Mississippi River Delta in 2015
The Mississippi River Deltaic Plain has extensive marsh habitats (fresh, intermediate, brackish, and saline) where soil cores were collected to a depth of 100 cm at 24 sites to assess long-term carbon accumulation rates and coast-wide burial rates. Each core was sectioned into 2-cm depth intervals, and select intervals were analyzed for percent moisture, bulk density, total carbon, and
DSWEmod surface water map composites generated from daily MODIS images - California DSWEmod surface water map composites generated from daily MODIS images - California
USGS researchers with the Patterns in the Landscape ? Analyses of Cause and Effect (PLACE) project are releasing a collection of high-frequency surface water map composites derived from daily Moderate Resolution Imaging Spectroradiometer (MODIS) imagery. Using Google Earth Engine, the team developed customized image processing steps and adapted the Dynamic Surface Water Extent (DSWE) to...
