Digital seafloor images, sediment grain size, bathymetry, and water velocity data from the lower Columbia River, Oregon and Washington, 2021 Digital seafloor images, sediment grain size, bathymetry, and water velocity data from the lower Columbia River, Oregon and Washington, 2021
Growth of subaqueous sand dunes commonly causes shoaling in engineered river channels that necessitates costly dredging to maintain adequate depths for navigation. The factors that result in sand wave growth are theoretically understood from laboratory experiments, but the capacity to predict sand wave geometries in field settings is limited due to temporal and spatial variability in...
Multichannel minisparker seismic-reflection and chirp subbottom data collected offshore Northern California during USGS field activity 2019-643-FA Multichannel minisparker seismic-reflection and chirp subbottom data collected offshore Northern California during USGS field activity 2019-643-FA
High-resoulution multichannel seismic-reflection (MCS) and Chirp sub-bottom data were collected by the U.S. Geological Survey in 2019 offshore Humboldt County of northern California to expand data coverage along the southern Cascadia Margin. Data were acquired to characterize offshore faults and to study sediment distribution. MCS and Chirp data were collected coincidentally and were...
Multichannel minisparker seismic-reflection data collected offshore Glacier Bay National Park during USGS field activity 2015-629-FA Multichannel minisparker seismic-reflection data collected offshore Glacier Bay National Park during USGS field activity 2015-629-FA
Multichannel seismic reflection data were collected by the U.S. Geological Survey in May of 2015 outside of Palma Bay, Alaska. Seismic data were acquired coincidentally with high resolution bathymetry (Dartnell and others, 2022). Data were acquired to map the offshore extension of the Queen Charlotte-Fairweather Fault. The fault has produced several significant earthquakes during the...
Hydrographic and sediment field data collected in the vicinity of Wainwright, Alaska, in 2009 Hydrographic and sediment field data collected in the vicinity of Wainwright, Alaska, in 2009
This dataset consists of hydrographic, geomorphic, and sediment field measurements obtained during the ice-free summer of 2009 in the vicinity of Wainwright, Alaska. Time-series data were collected with a bottom-mounted instrument package and consist of wave statistics, vertical water flow velocity profiles, water temperatures, conductivity, and salinity concentrations. Data collected at...
Overlapping seabed images and location data acquired using the SQUID-5 system at Looe Key, Florida, in July 2021, with structure-from-motion derived point cloud, digital elevation model and orthomosaic of submerged topography Overlapping seabed images and location data acquired using the SQUID-5 system at Looe Key, Florida, in July 2021, with structure-from-motion derived point cloud, digital elevation model and orthomosaic of submerged topography
Underwater images were collected using a towed-surface vehicle with multiple downward-looking underwater cameras developed by the U.S. Geological Survey (USGS). The system is named the Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). The raw images and associated navigation data were collected at Looe Key, a coral reef located within the...

Underwater images were collected in Lake Tahoe, CA, using a recently developed towed-surface vehicle with multiple downward-looking underwater cameras. The system is named the Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). The data were collected March 10th and 11th of 2021 to assess the accuracy, precision, and effectiveness of the new...
Overlapping lakebed images and associated GNSS locations acquired near Dollar Point, Lake Tahoe, CA, March 2021 Overlapping lakebed images and associated GNSS locations acquired near Dollar Point, Lake Tahoe, CA, March 2021
Underwater images were collected using a recently developed towed-surface vehicle with multiple downward-looking underwater cameras. The system is named the Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). However, there were only 4 cameras operational for this collection due to a cable failure. Images were collected March 10th and 11th of...
Marfac Machine Vision Camera Interface Marfac Machine Vision Camera Interface
This project contains the C# software developed to control and acquire imagery from a FLIR GigE machine vision camera. It is built using the FLIR Spinnaker 64bit SDK version 2.4.0.144 and requires the spinview application and associated dll's. This software was developed using Microsoft Visual Studio 2019 to control and acquire imagery from a GigE machine vision camera (Model: BFS-PGE...
Historical shorelines and morphological metrics for barrier islands and spits along the north coast of Alaska between Cape Beaufort and the U.S.-Canadian border, 1947 to 2019 Historical shorelines and morphological metrics for barrier islands and spits along the north coast of Alaska between Cape Beaufort and the U.S.-Canadian border, 1947 to 2019
A suite of morphological metrics were derived from existing shoreline and elevation datasets for barrier islands and spits located along the north-slope coast of Alaska between Cape Beaufort and the U.S.-Canadian border. This dataset includes barrier shorelines and polygons attributed with morphological metrics from five time periods: 1950s, 1980s, 2000s, 2010s, and 2020s.
Near-bed velocity measurements in Monterey Bay during arrival of the 2010 Chile Tsunami Near-bed velocity measurements in Monterey Bay during arrival of the 2010 Chile Tsunami
On February 27, 2010, a tsunami originating near Chile arrived in Monterey Bay, California. This data release comprises two hours of pressure and near-bed velocity data spanning the largest tsunami waves. At the time, the U.S. Geological Survey Pacific Coastal and Marine Science Center had a remotely-controlled instrumented platform deployed adjacent to the Santa Cruz Municipal Wharf...
