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)
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
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
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
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...
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...
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...
Data Supporting Mobile Wind Measurements Using a Joust Configured Ultrasonic Anemometer Onboard a Multi-rotor sUAS
These data were collected to investigate how well wind speed and direction can be measured using a miniature sonic anemometer mounted in a joust configuration on a small uncrewed aircraft system (sUAS). Test flights occurred at a bog within Interior Alaska that was instrumented with an eddy covariance flux tower. Part of the tower's instrumentation was a highly accurate sonic anemometer...
Geochemical, grain size, lithological, diatom, bathymetric, and age model data for Wildcat Lake, Point Reyes National Seashore 2021
These data are the geochemical (from X-ray fluorescence spectrometry), grain size, lithological (loss on ignition), diatom assemblages (taxa counts), bathymetric, and radioactive isotopes (210-Pb, 137Cs) from sediments from Wildcat Lake, Point Reyes National Seashore, California, USA starting in 2021. Taken together, they provide evidence for extreme precipitation events linked to...
Preserving Tree-Ring Datasets for Climate and Hazard Research and Understanding Societal Impacts: Colorado Fire, Climate, Humans
Culebra Range of the Sangre de Cristo Mountains, Colorado. Sample Collection: Ponderosa pine (Pinus ponderosa), Douglas-fir (Pseudotsuga menziesii), Bristlecone pine (Pinus aristate), and Limber pine (Pinus flexilis) living in lower and upper montane slopes of the Culebra Range (~Latitude 37˚N, ~Longitude -105˚W WGS84). The Fire-Climate-Human NGGDPP archive collection was obtained in two...
Digital Elevation Model (DEM) Derived Topographic Indices Across Sequoia Groves in Sequoia-Kings Canyon National Park and Yosemite National Park
This dataset provides topographic indices derived from 1 m resolution DEMs for sequoia groves in both Sequoia-Kings Canyon and Yosemite National Parks. All mapped sequoia groves in Sequoia-Kings Canyon National Park and two groves from Yosemite National Park, Merced and Mariposa, are included. For each grove, aspect, slope, the stream network, height above nearest drainage (HAND), depth...
