Projected change in seven annual phenology metrics under future climate scenarios in the U.S. Southwest Projected change in seven annual phenology metrics under future climate scenarios in the U.S. Southwest
The dataset includes processing scripts and 42 raster files of predicted change (delta) in annual vegetation phenology under future climate scenarios in the U.S. Southwest, using different combinations of phenology metrics, time periods, and emissions scenarios. Delta values are median projected changes across 10 global climate models and are relative to a reference period of 1981-2010

This dataset consists of annual raster maps of projected future ecosystem carbon stocks and fluxes, land use and land cover (LULC) classes, and LULC transitions for California, U.S. from 2021-2065. Data are simulation model output from the Land Use and Carbon Simulator (LUCAS; Sleeter et al. 2022) run under different future climate and land management scenarios. LUCAS model simulations...
Projected historic and future wetland carbon stocks, fluxes, and land cover under alternative restoration scenarios for four National Park Service lands Projected historic and future wetland carbon stocks, fluxes, and land cover under alternative restoration scenarios for four National Park Service lands
This dataset provides annual raster maps of ecosystem carbon stocks and fluxes following restoration within four National Park Service lands the Ackerson Meadow restoration project in Yosemite National Park, Captain John Smith Chesapeake National Historic Trail, Indiana Dunes National Park, and Cape Cod National Seashore. Data were produced using the Land Use and Carbon Simulator (LUCAS...
Projected proportional change in population density for American pronghorn under future climate scenarios in the U.S. Southwest Projected proportional change in population density for American pronghorn under future climate scenarios in the U.S. Southwest
Projected proportional change in American pronghorn (Antilocapra americana) population density in the U.S. Southwest under future climate scenarios. Projections are available for all combinations of three future time periods (2021-2050 ["2030s"], 2041-2070 ["2050s"], and 2061-2090 ["2070s"]), two emissions scenarios (RCP4.5 and RCP8.5), and two statistical models (means and extremes)...
Projected proportional change in wildlife population measures for Scaled Quail, Gambel's Quail, and Gunnison's prairie dog under future climate scenarios in the U.S. Southwest Projected proportional change in wildlife population measures for Scaled Quail, Gambel's Quail, and Gunnison's prairie dog under future climate scenarios in the U.S. Southwest
The dataset includes 36 raster files of predicted proportional change in wildlife population measure for different combinations of species, statistical model, time period, and emissions scenario. This collection includes all 36 possible combinations of three species (Gambel's Quail, Scaled Quail, and Gunnison's prairie dog), three future time periods (2021-2050, 2041-2070, and 2061-2090)...
PROSPER-rfops: Random Forest Operational Predictions of Streamflow Permanence for the Pacific Northwest (HU17) PROSPER-rfops: Random Forest Operational Predictions of Streamflow Permanence for the Pacific Northwest (HU17)
The PROSPER-rfops_HU17 rasters provide annual estimates of the probability of streamflow permanence for years 1989 through 2022 in the Pacific Northwest region of the United States, produced by the PRObability of Streamflow PERmanence Random Forest Operational (PROSPER-rfops) model. The model domain encompasses 12 four-digit Hydrologic Unit Code (HUC4) boundaries: 1701 (Kootenai-Pend...
qPCR data for assessing the effects of seasonality, density, and tide phase on detection of invasive European green crab eDNA in Washington state, 2022-2023 qPCR data for assessing the effects of seasonality, density, and tide phase on detection of invasive European green crab eDNA in Washington state, 2022-2023
The dataset supports studies performed in Washington state in 2022 and 2023 that investigated how detection of European green crab eDNA is affected by sampling season, green crab density, and the time at which samples are collected across a tide cycle. The data include sample site locations and descriptive categories, volume of water (L) filtered for eDNA analysis for each sampling event...

The content contains metadata from an eDNA survey that assessed the efficacy of an autonomous eDNA sampler for tracking Chinook, sockeye, and coho salmon migrating through the Lake Washington Ship Canal between June and September 2022.
Qualitative Analysis of Cyanotoxins in Lake Erie Samples Using Liquid Chromatography/High Resolution Mass Spectrometry (LC/HRMS) from July 2016 to October 2022 Qualitative Analysis of Cyanotoxins in Lake Erie Samples Using Liquid Chromatography/High Resolution Mass Spectrometry (LC/HRMS) from July 2016 to October 2022
Toxic harmful algal blooms are caused by cyanobacteria and can pose a threat to freshwater ecosystems, including the western basin of Lake Erie. Bloom toxicity can be influenced by variation of biosynthetic repertoires of toxic cyanobacteria but is not well studied beyond microcystins. Water samples collected by the National Oceanic and Atmospheric Administration from July 2016 through...

Radiocarbon, U-series, and amino acid chronology data for late Quaternary marine terraces in coastal Santa Barbara County, California, USA Radiocarbon, U-series, and amino acid chronology data for late Quaternary marine terraces in coastal Santa Barbara County, California, USA
In several early studies, central California marine terraces between Santa Barbara and Point Conception were interpreted to record sea-level high stands of the last interglacial complex, ~80 ka to ~120 ka (marine isotope stage [MIS] 5). These ages and their elevations (~20 m to ~45 m) indicate modest rates of tectonic uplift, similar to those from other localities in southern and central
