Multibeam sonar bathymetric data for the Miami Pockmark and Key Biscayne Pockmark

Multibeam sonar data showing the bathymetric survey of two offshore submarine sinkholes, Miami Sinkhole and Key Biscayne Sinkhole. A series of dives were performed to produce the bathymetric surveys using an autonomous underwater vehicle (AUV) with a multibeam-sonar. These data were collected between May 5-8, 2016 using a Bluefin B12 AUV equipped with a Imagenex MBDelta and an onboard cal

Hydrologic simulations using projected climate data as input to the Precipitation-Runoff Modeling System (PRMS) in the Upper Rio Grande Basin

The Rio Grande Basin Study (Basin Study) is a stakeholder-led project funded by the U.S. Bureau of Reclamation to develop climate adaptation strategies to address the growing gap between water supply and demand in the Upper Rio Grande Basin in Colorado, New Mexico, and Texas. The role of the USGS in the Basin Study is to simulate historic and future streamflow using projected climate data

Hydrologic and geophysical data from high-elevation boreholes in Redwell Basin near Crested Butte, Colorado: Hydrologic monitoring data

Boreholes were drilled in 2017 and 2018 in Redwell Basin, a headwater catchment underlain by hydrothermally altered sedimentary rock in the Elk Mountains near the town of Crested Butte, Colorado. Two boreholes were completed as vertically discrete nested monitoring wells (MW1 as MW1A-MW1D and MW2.1 as MW2.1A-MW2.1C) and one borehole was completed as a single monitoring well (MW2 as RP8%

Environmental DNA (eDNA) and fish capture data from Round Goby screening surveys on the Eastern Erie Canal, New York

The dataset is composed of two tables containing data collected during screening surveys for invasive Round Goby (Neogobius melanostomus) on the Eastern Erie Canal in New York. Environmental DNA using water samples and traditional fish surveys using benthic trawling, seining, and trapping were conducted twice annually at 12 sites on the Eastern Erie Canal between Oneida Lake and the Hudso

Seafloor Elevation Change From 2016 to 2017 at Looe Key, Florida Keys-Impacts From Hurricane Irma (version 2.0)

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify bathymetric changes at Looe Key near Big Pine Key, Florida (FL), within a 19.7 square-kilometer area following Hurricane Irma's landfall in September 2017. USGS staff used light detection and ranging (lidar)-derived data acquired by the National Oceanic and Atmospher

Hydrologic and geophysical data from high-elevation boreholes in Redwell Basin near Crested Butte, Colorado

Four boreholes (MW1, MW1UZ, MW2, MW2.1) were drilled in the fall of 2017 and summer of 2018 in upper Redwell Basin, a headwater catchment underlain by hydrothermally altered sedimentary rock in the Elk Mountains near the town of Crested Butte, Colorado. The boreholes were continuously cored using a wireline HQ-sized coring system and sample a combination of Quaternary-aged surficial

Tributary sand input data, Colorado River, Grand Canyon National Park, Arizona

These data were compiled from sampling pre-dam flood terraces and sand bar deposits of the Colorado River in Glen Canyon between Glen Canyon Dam and the Paria River confluence. This includes sand deposits from the 2008, 2012, 2013 and 2014 high flow experiments (HFE) in Marble Canyon. Sand sources from these locations were sampled in September/October of 2013 and 2014. Also, samples o

Alaska permafrost characterization: Electrical Resistivity Tomography Data & Models from 2019

Electrical resistivity tomography (ERT) measurements were collected by the U.S. Geological Survey (USGS) at two sites in Interior Alaska in September 2019 for the purposes of imaging permafrost structure and quantifying variations in subsurface moisture content in relation to thaw features. First, ERT data were collected at Big Trail Lake, a thermokarst lake outside of Fairbanks, Al
