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...
Wetlands in the state of Arizona Wetlands in the state of Arizona
We created a single map of surface water presence by intersecting water classes from available land cover products (National Wetland Inventory, Gap Analysis Program, National Land Cover Database, and Dynamic Surface Water Extent) across the U.S. state of Arizona. We derived classified samples for four wetland classes from the harmonized map: water, herbaceous wetlands, wooded wetlands...
Estuarine vegetated wetland change scenarios for estuaries in the conterminous United States, 1996–2019 Estuarine vegetated wetland change scenarios for estuaries in the conterminous United States, 1996–2019
This data release contains land cover-derived statistics regarding estuarine vegetated wetland area change within estuary drainage areas along the conterminous U.S. This dataset includes net change in estuarine vegetated wetland area based on National Oceanic and Atmospheric Administration's (NOAA) Coastal Change Assessment Program (C-CAP) 1996 and 2016 land cover data. Net change was...
Stable hydrogen and oxygen isotopic compositions of precipitation samples from selected Colorado and Utah National Atmospheric Deposition Program (NADP) sites Stable hydrogen and oxygen isotopic compositions of precipitation samples from selected Colorado and Utah National Atmospheric Deposition Program (NADP) sites
The stable hydrogen (delta 2H) and oxygen (delta 18O) isotopic compositions of more than 4,300 weekly composite samples of precipitation from thirteen National Atmospheric Deposition Program (NADP) sites (CO02, CO08, CO09, CO10, CO21, CO89, CO91, CO92, CO93, CO96, CO97, CO98, and UT09) in Colorado and Utah were analyzed on archived samples obtained from NADP over various time periods...
Data release for Late glacial-Younger Dryas climate in interior Alaska as inferred from the isotope values of land snail shells Data release for Late glacial-Younger Dryas climate in interior Alaska as inferred from the isotope values of land snail shells
The isotopic values of fossil snail shells can be important archives of past climate. Here we present the first carbon (δ13C) and oxygen (δ18O) isotope values of radiocarbon-dated and live-collected snails in interior Alaska to explore changes in vegetation and humidity through the late glacial period (14-11.7 ka). Snail shell δ13C values were relatively consistent through the late...
