Underwater Photogrammetry Products of Big Pine Ledge, Florida From Images Acquired Using the SQUID-5 System in July 2022 Underwater Photogrammetry Products of Big Pine Ledge, Florida From Images Acquired Using the SQUID-5 System in July 2022
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 Big Pine Ledge, a coral reef located within...

Sediment core data from offshore southern Cascadia during field activity 2019-643-FA Sediment core data from offshore southern Cascadia during field activity 2019-643-FA
This data release contains sediment core data including core imagery, multi-sensor core logger (MSCL) data, and radiocarbon age data. Sediment cores were collected offshore northern California during U.S. Geological Survey cruise 2019-643-FA aboard the M/V Bold-Horizon. The cores were collected along with geophysical data to evaluate potential hazards (e.g., active fault systems, slope
High-resolution Geophysical and Imagery Data Collected in May 2023 Near Fort Hase, Marine Corps Base Hawaii High-resolution Geophysical and Imagery Data Collected in May 2023 Near Fort Hase, Marine Corps Base Hawaii
Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS – SPCSMC), conducted a geophysical and imagery survey around Fort Hase Marine Corps Base Hawaii (MCBH) and Coconut Island, on the island of Oahu, Hawaii (HI), during May 2023. During this study, multibeam bathymetry and acoustic backscatter data were collected...

The development of small, cabled, real-time video based observation systems for near shore coastal marine science including three examples and lessons learned The development of small, cabled, real-time video based observation systems for near shore coastal marine science including three examples and lessons learned
The effects of climate change on the near shore coastal environment including ocean acidification, accelerated erosion, destruction of coral reefs, and damage to marine habitat have highlighted the need for improved equipment to study, monitor, and evaluate these changes [1]. This is especially true where areas of study are remote, large, or beyond depths easily accessible to divers. To...

Autonomous bed-sediment imaging-systems for revealing temporal variability of grain size Autonomous bed-sediment imaging-systems for revealing temporal variability of grain size
We describe a remotely operated video microscope system, designed to provide high-resolution images of seabed sediments. Two versions were developed, which differ in how they raise the camera from the seabed. The first used hydraulics and the second used the energy associated with wave orbital motion. Images were analyzed using automated frequency-domain methods, which following a...

Seabed ripple morphology and surficial sediment size at the SAX04 experiments near Fort Walton Beach, Florida, fall 2004 Seabed ripple morphology and surficial sediment size at the SAX04 experiments near Fort Walton Beach, Florida, fall 2004
Data presented in this report originates from measurements obtained off the Florida coast (fig. 1) as part of the Sediment Acoustics Experiment (SAX04) and Ripples Department Research Initiative (DRI) (Office of Naval Research (ONR), Critical Benthic Environmental Processes and Modeling, Long Range BAA 04-001, Sept. 10, 2003). The aim of this document is to present methods employed to...

High-resolution topographic, bathymetric, and oceanographic data for the Pleasure Point area, Santa Cruz County, California: 2005-2007 High-resolution topographic, bathymetric, and oceanographic data for the Pleasure Point area, Santa Cruz County, California: 2005-2007
The County of Santa Cruz Department of Public Works and the County of Santa Cruz Redevelopment Agency requested the U.S. Geological Survey (USGS) Western Coastal and Marine Geology Team (WCMG) to provide baseline geologic and oceanographic information on the coast and inner shelf at Pleasure Point, Santa Cruz County, California. The rationale for this proposed work is a need to better...
