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.

Projected mangrove distribution and ecosystem properties in the southeastern United States under climate change Projected mangrove distribution and ecosystem properties in the southeastern United States under climate change
We evaluated changes in mangrove distribution and ecosystem properties in the southeastern United States under climate change using known climate-ecological relationships, recent climate data for the period 1981-2010, and future projected climate data for the period 2071-2100 under two Shared Socio-economic Pathways (SSPs): the SSP2-4.5 and SSP5-8.5 scenarios, which correspond to...
Annual End-of-Summer Snow Cover on Glaciers in Alaska and Northwest Canada Annual End-of-Summer Snow Cover on Glaciers in Alaska and Northwest Canada
This dataset contains observations of the distribution of end-of-summer snow cover on approximately 3000 glaciers across Alaska and Northwest Canada. The data are provided as: (1) GeoTIFF rasters indicating the spatial extent of end-of-summer snow cover on each glacier's surface in each year (one raster per glacier per year), and (2) yearly tables with the equilibrium line altitude and...
Occurrences of Pliocene Planktic foraminifers in core samples from SE Florida Occurrences of Pliocene Planktic foraminifers in core samples from SE Florida
Data consist of presence / absence records of planktic foraminifer species from 5 core samples at 3 localities in southeast Florida. Samples are placed in biostratigraphic zones and ages are estimated from calibrated first and last appearances of select taxa.
Everglades mangrove vegetation data from 23 long-term plots (1992-2011) Everglades mangrove vegetation data from 23 long-term plots (1992-2011)
Twenty-three long-term mangrove vegetation plots were established between 1992-1997 within the southwest coastal region of Everglades National Park (Florida, USA) to quantify tree damage and recovery following hurricanes and to understand the effects of global climate change. Many of the mangrove vegetation plots were associated with hydrology, soil porewater, and soil surface elevation...
Digitized mangrove-marsh ecotone boundaries for Everglades National Park and Big Cypress National Preserve (Florida, USA) in 2013 and 2019 Digitized mangrove-marsh ecotone boundaries for Everglades National Park and Big Cypress National Preserve (Florida, USA) in 2013 and 2019
This dataset consists of a file geodatabase containing the digitized ecotone boundaries between mangroves and freshwater marsh in 2013 and 2019 at 14 systematically selected segments in Big Cypress National Preserve and Everglades National Park (southwest Florida, USA).
CMIP6-LOCA2 threshold and extreme event metric projections from 1950-2100 for the Contiguous United States CMIP6-LOCA2 threshold and extreme event metric projections from 1950-2100 for the Contiguous United States
Projections of extreme event metrics and threshold exceedances are produced by analyzing the Climate Model Intercomparison Program Phase 6 Localized Constructed Analogs (CMIP6-LOCA2) data set. The primary daily temperature and precipitation data are summarized to 36 annual metrics and 4 monthly metrics. This data set includes output from 27 GCMs for the period 1950-2100 under ssp245...
Geochemical, grain size, lithological, bathymetric, reconstructed integrated vapor transport, and age model data for Leonard Lake, Mendocino County Geochemical, grain size, lithological, bathymetric, reconstructed integrated vapor transport, and age model data for Leonard Lake, Mendocino County
The data herein are geochemical (from X-Ray fluorescence spectrometry), grain size (percent clay, silt, sand), lithological (loss on ignition data), bathymetric, reconstructed IVT, and radioactive isotopes (14-C, 210-Pb, 226-Ra, and 137-Cs). These data were collected from sediments from Leonard Lake, Mendocino County, California, USA starting in 2014. Together, these data provide...
Plant, soil, and microbial characteristics of marsh collapse in Mississippi River Deltaic wetlands Plant, soil, and microbial characteristics of marsh collapse in Mississippi River Deltaic wetlands
Site, field, and soil data collected from 14 sites along a chronosequence of wetland submergence on 15 – 17 October 2019 in a Louisiana salt marsh in Barataria Basin, part of the Mississippi River Deltaic Plain, along the northern Gulf of Mexico coast.
Plant composition, shrub biomass, and soil biogeochemistry from an experimental drought treatment on the Colorado Plateau Plant composition, shrub biomass, and soil biogeochemistry from an experimental drought treatment on the Colorado Plateau
These data were compiled for a study that investigated the effects of drought seasonality and plant community composition in a dryland ecosystem. In 2015 U.S. Geological Survey ecologists recorded vegetation and soil moisture data in 36 experimental plots which manipulated precipitation in two plant community types. The experiment consisted of three precipitation treatments: control...
Continuous water-quality data for selected streams in Rocky Mountain National Park, Colorado, water years 2011 - 19 (ver. 3.0, October 2023) Continuous water-quality data for selected streams in Rocky Mountain National Park, Colorado, water years 2011 - 19 (ver. 3.0, October 2023)
This data release contains water-quality and discharge data collected at seven stream sites and one groundwater spring in Rocky Mountain National Park (RMNP), Colorado by the U.S. Geological Survey (USGS) from 10/1/2010 to 9/30/2019 using in-situ sensors and field meters. Data were collected for the purpose of quantifying downstream transport of aquatic carbon and exchange fluxes of...
Depth to frozen soil measurements at APEX, 2008-2023 Depth to frozen soil measurements at APEX, 2008-2023
Depth to frozen soil measurements taken by a variety of collaborators at the Alaskan Peatland EXeriment (APEX) bog/permafrost plateau site. Data is from 2018 - 2023.
Sr/Ca and Linear Extension Data for a Modern Orbicella faveolata Colony From Marquesas Keys, Florida, USA Sr/Ca and Linear Extension Data for a Modern Orbicella faveolata Colony From Marquesas Keys, Florida, USA
The coral Strontium/Calcium (Sr/Ca) paleothermometer can provide a powerful proxy for centennial-scale sea-surface temperature (SST) variability in the Caribbean/Atlantic Ocean region. This data release presents a new, 150-year proxy reconstruction (1830-1980 C.E.) of monthly-resolved Sr/Ca-based SST estimates from the coral species Orbicella faveolata collected from the Marquesas Keys...
