SQUID-5 in the water
The SQUID-5 is an acronym for a Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with 5 cameras. Developed by the USGS Pacific Coastal and Marine Science Center Marine Facility (MarFac), SQUID-5 is a towed surface vehicle with an onboard Global Navigation Satellite System (GNSS) and 5 downward-looking cameras with overlapping views of the seafloor. It was first field-tested in July of 2019 in the Florida Keys over a shallow-water coral reef. Here, some curious dolphins frolic nearby as SQUID-5 is towed from a boat.
