Multiproxy paleoecological data from Santa Fe Lake, NM Multiproxy paleoecological data from Santa Fe Lake, NM
This data release contains paleoecological records from Santa Fe Lake, NM USA. Santa Fe Lake is a small (1.4 ha), subalpine lake in the Sangre de Cristo Mountain Range of the Southern Rocky Mountains (35.79°N, 105.78°W, 3532 m a.s.l). Overlapping sediment cores were taken from Santa Fe Lake in September, 2020 in 5.4 m of water from a coring platform with a Livingstone square-rod piston...
Soil data release of Open-File Report 02-277, collected on marine terraces near Santa Cruz, California in 1981 Soil data release of Open-File Report 02-277, collected on marine terraces near Santa Cruz, California in 1981
This data release represents samples collected in 1981 along a series of five marine terraces between Ano Nuevo and Santa Cruz in California as a part of a U.S. Geological Survey project led by Dennis Marchand to study soil chronosequences in the Western United States. These sequential surfaces of soils have similar key elements for development in the slope, climate, vegetation, and...
Historical simulated snowpack for the Willow Creek and Big Thompson, Colorado watersheds and vicinity, water years 1994-2023 Historical simulated snowpack for the Willow Creek and Big Thompson, Colorado watersheds and vicinity, water years 1994-2023
This data release contains historical SnowModel outputs for the Willow Creek and Big Thompson, CO watersheds and surrounding area. Simulated outputs were produced on a 30 meter (m) geospatial grid and forced using meteorology from the National Land Data Assimilation System (NLDAS-2). These simulations used daily snow water equivalent (SWE) time-series from 13 National Resources...
Data release for The ichnology of White Sands (New Mexico): linear traces and human footprints, evidence of transport technology? Data release for The ichnology of White Sands (New Mexico): linear traces and human footprints, evidence of transport technology?
This dataset lists the values of experiments with modern travois. The abstract of the associated interpretive product describing the findings at the site is as follows: A travois is crafted from one or more wooden poles and is one of the simplest pre-historic vehicles. Although these devices likely played vital roles in the lives of ancient peoples, they have low preservation potential...
Surface Elevation Tablet Measurements from 10 USGS Sites Along the US Atlantic Coast (2005-2020) Surface Elevation Tablet Measurements from 10 USGS Sites Along the US Atlantic Coast (2005-2020)
Here we provide data used to report on changes in tidal marsh elevation in relation to our network of 20 fixed benchmarks located across a geographically broad network of coastal elevation monitoring stations with standard monitoring protocols. This dataset includes Surface Elevation Table (SET) measurements taken from 10 sites along the US Atlantic coast, ranging from Virginia to Maine...
Streamgage Attributes, Basin Characteristics, Subsidies from Glacier Mass Loss, and Streamflow Statistics, Selected Streamgages in Alaska, 2000-2019 Streamgage Attributes, Basin Characteristics, Subsidies from Glacier Mass Loss, and Streamflow Statistics, Selected Streamgages in Alaska, 2000-2019
This data package contains 3 tables presenting site selection information, basin characteristics, subsidy to streamflow from glacier mass loss data, and other streamflow statistics for selected streamgages in Alaska that were used to evaluate the influence of glacier mass loss on streamflow in Alaska and conterminous basins in Canada. The first ("site_selection_outcomes.csv") contains...
Data to support the role of the American Alligator (Alligator mississippiensis) in coastal wetland carbon dynamics Data to support the role of the American Alligator (Alligator mississippiensis) in coastal wetland carbon dynamics
Coastal wetlands store carbon in their soils. Carbon is produced by emergent biomass and in-situ root growth, as well as deposited through sedimentation. Burial of aboveground carbon within soils and disruption of long-term soil carbon storage are both influenced by the fauna present in coastal wetlands. Data were used to test the hypothesis that the American Alligator (Alligator...
Sr/Ca, Oxygen Isotope, and Linear Extension Data for Five Holocene Orbicella faveolata Corals from Dry Tortugas and Marquesas Keys, Florida, USA Sr/Ca, Oxygen Isotope, and Linear Extension Data for Five Holocene Orbicella faveolata Corals from Dry Tortugas and Marquesas Keys, Florida, USA
This data release contains new, 40–70-year long sub-annual strontium-to-calcium ratio (Sr/Ca) records and linear extension measurements from five mid-to-late Holocene, Orbicella faveolata corals from the Dry Tortugas National Park (DT) and Marquesas Keys (MK), Florida (FL). U.S. Geological Survey (USGS) researchers used these Sr/Ca data to calculate sea-surface temperature (SST) using...
Surface Water Index of Permanence (SWIPe) for the upper Missouri River basin, 1989-2021 Surface Water Index of Permanence (SWIPe) for the upper Missouri River basin, 1989-2021
With the Surface-Water Index of Permanence (SWIPe) we provide a standardized metric for describing one- to five-year anomalies of the annual minimum surface-water extent of streams and wetlands for multiple spatial scales including basin (4-digit hydrologic unit codes [HUCs]) to subwatersheds (12-digit HUCs). Drier conditions are represented by negative SWIPE values that range from 0 to...
Loch Vale Watershed hydroclimate and isotopes of tree-ring cellulose and source-water isotope model Loch Vale Watershed hydroclimate and isotopes of tree-ring cellulose and source-water isotope model
Stable isotopes of water preserved in geologic archives, primarily as oxygen (d18O), have proven critical for documenting Earth’s climatic and hydrologic systems past and present. However, timescale differences of water isotope inputs to proxy systems and the signal embedded in long paleorecords often confound translation to observed hydroclimatic metrics. Here, a unique 20-year dataset...
Biogeochemical Data from Field Samples and Laboratory Experiments, Boulder Creek Watershed, Colorado (2019-2023) Biogeochemical Data from Field Samples and Laboratory Experiments, Boulder Creek Watershed, Colorado (2019-2023)
Biogeochemical processes are key drivers of chemical solubility and mobilization. Understanding these processes will lead to improved predictive capabilities and may aid with watershed management decisions. This data release presents results from the Boulder Creek, Colorado watershed, including analyses of water and sediment. From April to August 2019, water samples were collected weekly...
Mid-Holocene-to-present Modeled (ca., 7,000 to 100 cal. BP) and Reconstructed (ca., 5,900 to 5,436 cal. BP) Temperature for the High-Elevations of the Greater Yellowstone Ecosystem: Derived from a Transient Climate Model and Whitebark Pine Tree-rings Mid-Holocene-to-present Modeled (ca., 7,000 to 100 cal. BP) and Reconstructed (ca., 5,900 to 5,436 cal. BP) Temperature for the High-Elevations of the Greater Yellowstone Ecosystem: Derived from a Transient Climate Model and Whitebark Pine Tree-rings
In the Rocky Mountains of the Greater Yellowstone Ecosystem (United States), recent melting at a high-elevation (3,091 m asl) ice patch exposed a mature stand of whitebark pine (Pinus albicaulis) trees located ~180 m above modern treeline dating to the mid-Holocene (c. 5,900-5,436 cal y BP +- 51 y). From this subfossil wood record, we contextualize the recent magnitude of warming...
