The Saildrone Voyager is a ten m uncrewed floor automobile (USV) designed for seafloor mapping at depths as much as 300 m. | Supply: Saildrone
Two Saildrone Voyager uncrewed floor autos, or USVs, have surveyed 1,500 sq. nautical miles (5,144.8 sq. km) in a north-central space of the Gulf of Maine. The marine robots mapped areas that had by no means been mapped in excessive decision.
This expedition helps deep-sea coral surveys and different missions of the Nationwide Oceanic and Atmospheric Administration (NOAA).
The Gulf of Maine, which is bordered by Massachusetts, New Hampshire, and Maine, in addition to the Canadian provinces of New Brunswick and Nova Scotia, is a productive and dynamic marine atmosphere. Its waters are dwelling to a various array of economically necessary fisheries, together with Atlantic cod, herring, lobster, and scallops.
As well as, the gulf homes distinctive underwater habitats, together with kelp forests, eelgrass beds, and deep-sea coral. All of those might present shelter and breeding grounds for a lot of marine organisms.
Saildrone Inc. stated it creates uncrewed floor autos (USVs) that may cost-effectively collect knowledge for science, fisheries, climate forecasting, and extra. The Alameda, Calif.-based firm makes use of autonomous vessels to ship observations and insights about exercise above and beneath the ocean floor.
The Surveyor, Explorer, and Voyager USVs are powered by renewable wind and photo voltaic vitality. They constantly feed knowledge in actual time to drive extra knowledgeable decision-making throughout maritime safety, commerce, and sustainability, stated Saildrone.
Why is the Gulf of Maine so necessary?
Along with its various wildlife, the Gulf of Maine’s seafloor has a posh topography of sea basins, shallow banks, and steep slopes. Nonetheless, high-resolution mapping knowledge has been extraordinarily restricted, particularly in deeper waters.
The Unique Financial Zone (EEZ) typically extends from the coast to 200 nautical miles (370.4 km) offshore. That is the maritime zone for which a coastal nation has jurisdiction over pure assets.
Over 4 million sq. mi. (10.3 million sq. km), the U.S. EEZ is bigger than all 50 states mixed, but 48% stays unmapped and unexplored, in accordance with Saildrone. Correct ocean depths and topography are important for useful resource administration and responsibly growing and sustaining coastal infrastructure.
To enhance understanding of the seafloor, the federal authorities established the “Technique for Mapping, Exploring, and Characterizing the US Unique Financial Zone” (NOMEX). The Gulf of Maine is without doubt one of the highest mapping priorities as a result of its important business fisheries supported by various habitats and the potential to help wind vitality.
Particularly, good mapping knowledge is important to information the seek for deep-sea coral, which serves as a habitat for necessary fisheries, Saildrone famous.

Saildrone’s mission primarily targeted on the Jordan and Georges Basins, at depths of as much as 300 m (984.2 ft.). The corporate’s knowledge revealed a posh and diverse underwater panorama, reflecting its glacial historical past and dynamic oceanographic processes.
“The Saildrone Voyagers are filling in a considerable hole in seafloor knowledge within the Gulf of Maine,” stated Heather Coleman, a researcher within the Deep Sea Coral Analysis and Expertise Program below the NOAA Fisheries Workplace of Habitat Conservation.
“NOAA and companions are very keen on higher understanding habitats within the area that will help fish manufacturing,” she added. “These high-resolution seafloor maps will inform future surveying and modeling efforts, in addition to support within the New England Fishery Administration Council’s (NEFMC) fishery administration selections.”
Voyager is a 10-m (33-ft.) USV designed particularly for near-shore ocean and lakebed mapping. It carries a payload of science sensors and mapping echo sounders, in addition to navigation and communications tools.
Saildrone stated Voyager can ship long-duration Worldwide Hydrographic Group (IHO)-compliant multibeam mapping surveys and ocean knowledge assortment. Whereas the corporate’s USVs are primarily wind and solar-powered, Voyager additionally carries a high-efficiency electrical motor for velocity and maneuverability in gentle winds.
Undersea knowledge has a number of makes use of
The multibeam and backscatter knowledge collected within the Gulf of Maine will inform new species-distribution fashions, which was beforehand not potential with the shortage of high-resolution seafloor data. These new maps may also assist replace nautical charts and support navigation, filling necessary gaps in bathymetric protection.
“That is the primary profitable demonstration of Saildrone Voyager mapping capabilities, pushing the envelope of what’s potential utilizing autonomous programs for shallow to mid-depth EEZ mapping,” stated Brian Connon, vice chairman of ocean mapping at Saildrone. “Its state-of-the-art Norbit multibeam echo sounder, mixed with near-silent operations and classification from the American Bureau of Transport, make Saildrone’s Voyager the USV of alternative for near-shore mapping.”
“These capabilities could be utilized for any variety of missions, from habitat exploration to security of navigation to web site characterization for offshore wind,” he asserted.
Saildrone has been working autonomous knowledge assortment missions for ocean analysis, seafloor mapping, and maritime safety since 2015. Thus far, it has constructed greater than 140 USVs throughout the three Explorer, Voyager, and Surveyor courses.
The Saildrone fleet has already spent greater than 42,000 days at sea and sailed greater than 1.3 million nm (240,000 km) from the Excessive North to the Southern Ocean. Earlier this month, Saildrone started a mission to map 29,300 sq. nm (10,000 sq. km) of the Cayman Islands’ EEZ.
