Scanned field notebooks from a USGS Benchmark Glacier: South Cascade Glacier, Washington,1957 - 2022 Scanned field notebooks from a USGS Benchmark Glacier: South Cascade Glacier, Washington,1957 - 2022
This data release is a collection of data and field notes documenting snow and ice changes on South Cascade Glacier, Washington, USA. The field records relate to glaciological research and reflect evolving interpretations of glacier mass balance, climatology, hydrology, and other glacier-related research conducted at the site between 1957 to 2022 in association with the USGS Benchmark...
Vegetation cover, ground cover, plant mortality, and species abundance across an experimental drought treatment on the Colorado Plateau from 2010-2022 Vegetation cover, ground cover, plant mortality, and species abundance across an experimental drought treatment on the Colorado Plateau from 2010-2022
These data were compiled to assess the response of vegetation and biological soil crusts to drought in a semi-arid ecosystem on the Colorado Plateau near Moab, Utah. Objective(s) of our study were to explore how vegetation cover, soil conditions, and growing season nitrogen (N) availability are impacted by multifaceted drying climate conditions using data from a long-term precipitation...
Sapflow data from two separate but adjoining ecotones on Bannockburn Plantation near Georgetown, South Carolina, USA (2008 and 2009) Sapflow data from two separate but adjoining ecotones on Bannockburn Plantation near Georgetown, South Carolina, USA (2008 and 2009)
These data support a sap flow study, as represented by dual temperature differentials between heated and unheated probes inserted into trees. Data are from two separate field sites, with five tree species recorded every 30 minutes during the time periods of June 29 to August 24, 2008, and March 5 to June 1, 2009. Data were collected from a longleaf pine plantation (Pinus palustris) and a
Alkenone temperature estimates from the Miocene (Burdigalian, Langhian, Tortonian) and Pliocene (Zanclean) Atlantic Coastal Plain sediments Alkenone temperature estimates from the Miocene (Burdigalian, Langhian, Tortonian) and Pliocene (Zanclean) Atlantic Coastal Plain sediments
This dataset collects sea surface temperature data generated through alkenone analysis of Neogene sediments collected from cores and outcrops of the Virginia and Maryland Atlantic Coastal Plain.
Data release for Ice and ocean constraints on early human migrations into North America along the Pacific coast Data release for Ice and ocean constraints on early human migrations into North America along the Pacific coast
Founding populations of the first Americans likely occupied parts of Beringia during the Last Glacial Maximum (LGM) (1). The timing, pathways, and modes of their southward transit remain unknown, but blockage of the interior route by North American ice sheets between ~26-14 cal kyr BP (ka) favors a coastal route during this period. Using models and paleoceanographic data from the North...
Maps of early season invasive grasses and hot spots in the Mojave Ecoregion from 2009-2020 Maps of early season invasive grasses and hot spots in the Mojave Ecoregion from 2009-2020
Maps of invasive annual grasses were created using multi-season Landsat imagery over a 12 years period (2009-2020), and validated using an extensive network of plot data. Annual maps were used to identify persistent and productive populations of invasive annual grass, called hot spots, across entire Mojave Desert ecoregion. The data provided include a 12 band raster geospatial data file...
Meteorological measurements from five weather stations in Grand and San Juan Counties in southeastern Utah (ver. 3.0, September 2024) Meteorological measurements from five weather stations in Grand and San Juan Counties in southeastern Utah (ver. 3.0, September 2024)
These data were compiled from six automated weather stations that together provide several points in the meteorological record across a latitudinal and elevational gradient in southeastern Utah. Recorded data from these weather stations are associated with several different studies. Meteorological data are important for quantifying short term weather events as well as longer term climate...
Simulated annual area burned for eleven extensively forested ecoregions in the western United States for 1980 - 2099 Simulated annual area burned for eleven extensively forested ecoregions in the western United States for 1980 - 2099
This data release provides output produced by a statistical, aridity threshold fire model for 11 extensively forested ecoregions in the western United States. We identified thresholds in fire-season climate water deficit (FSCWD) that distinguish years with limited, moderate, and extensive area burned for each ecoregion. We developed a new area burned model using these relationships and...
Diel and synoptic sampling data from Boulder Creek and South Boulder Creek, near Boulder, Colorado, September–October 2019 Diel and synoptic sampling data from Boulder Creek and South Boulder Creek, near Boulder, Colorado, September–October 2019
Multiple sampling campaigns were conducted near Boulder, Colorado, to quantify constituent concentrations and loads in Boulder Creek and its tributary, South Boulder Creek. Diel sampling was initiated at approximately 1100 hours on September 17, 2019, and continued until approximately 2300 hours on September 18, 2019. During this time period, samples were collected at two locations on...
Hydrogeomorphic data along transitioning Coastal Plain rivers (Mattaponi and Pamunkey Rivers): implications for a rising sea level Hydrogeomorphic data along transitioning Coastal Plain rivers (Mattaponi and Pamunkey Rivers): implications for a rising sea level
Data on changing hydrogeomorphic characteristics along river gradients from nontidal through tidal freshwater to oligohaline reaches along the Mattaponi and Pamunkey Rivers, Virginia. Shapefile data include location and elevation profiles of the river valleys along multiple digital cross-sections from lidar digital elevation models, satellite visible imagery, and geographic information...
Soil and Vegetation Data from Lake-Margin Wetlands in the Yukon Flats National Wildlife Refuge Soil and Vegetation Data from Lake-Margin Wetlands in the Yukon Flats National Wildlife Refuge
This data release includes six child items of soil and vegetation data from lake margin soils of the Yukon Flats National Wildlife Refuge, Alaska. Data includes multiple lakes that are defined as either stable or drying. Lake margin vegetation communities include graminoid, shrub, and forest. Sols are separated into organic and mineral layers. Microbial data includes different...
PRISM4 (mid-Piacenzian) Paleoenvironmental Reconstruction Data PRISM4 (mid-Piacenzian) Paleoenvironmental Reconstruction Data
The mid-Piacenzian is known as a period of relative warmth when compared to the present day. A comprehensive understanding of conditions during the Piacenzian serves as both a conceptual model and a source for boundary conditions as well as means of verification of global climate model experiments. These data are provided as digital representations of mid Pliocene boundary conditions...
