Archive of Digitized Analog Boomer Seismic Reflection Data Collected from the Northern Gulf of Mexico: Intersea 1980 Archive of Digitized Analog Boomer Seismic Reflection Data Collected from the Northern Gulf of Mexico: Intersea 1980
The U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program (CMHRP) has actively collected geophysical and sedimentological data in the northern Gulf of Mexico for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s most HRSP data were collected in analog format as paper rolls...

This data release includes metadata and tabular datasets that document (1) Ceratocystis qPCR DNA detections in Passive Environmental Samplers (PES), (2) Ceratocystis qPCR DNA detections after pre-amplification, (3) wood and frass particle counts detected in PES (4) location of individual PES within the study area (5) ambrosia beetle gallery counts on felled 'ohi'a (6) ambrosia beetle...
Landscape inputs and simulation output for the LANDIS-II model in the Greater Yellowstone Ecosystem Landscape inputs and simulation output for the LANDIS-II model in the Greater Yellowstone Ecosystem
This data release provides inputs needed to run the LANDIS-II landscape change model, NECN and Base Fire extensions for the Greater Yellowstone Ecosystem (GYE), USA, and simulation results that underlie figures and analysis in the accompanying publication. We ran LANDIS-II simulations for 112 years, from 1988-2100, using interpolated weather station data for 1988-2015 and downscaled...
Loch Lomond Reservoir 2019 Survey Data Loch Lomond Reservoir 2019 Survey Data
This dataset contains the digital elevation model from the bathymetric survey, along with the sediment samples, stage-area table, stage-storage table, and 20-ft contours of the reservoir.
Alaska permafrost characterization: Geophysical and related field data collected from 2019-2020 Alaska permafrost characterization: Geophysical and related field data collected from 2019-2020
Geophysical measurements were collected by the U.S. Geological Survey (USGS) at two sites in Interior Alaska in 2019 and 2020 for the purposes of imaging permafrost structure and quantifying variations in subsurface moisture content in relation to thaw features. In September 2019, electrical resistivity tomography (ERT) and downhole nuclear magnetic resonance (NMR) data were used to...
Interferometric synthetic aperture radar data from 2020 for landslides at Barry Arm Fjord, Alaska Interferometric synthetic aperture radar data from 2020 for landslides at Barry Arm Fjord, Alaska
Subaerial landslides at the head of Barry Arm Fjord in southern Alaska could generate tsunamis (if they rapidly failed into the Fjord) and are therefore a potential threat to people, marine interests, and infrastructure throughout the Prince William Sound region. Knowledge of ongoing landslide movement is essential to understanding the threat posed by the landslides. Because of the...
