Saildrone Completes Groundbreaking Unmanned Ocean Mapping Mission

Saildrone, a leading autonomous vessel company, has successfully completed a groundbreaking ocean survey mission in remote areas off California and Alaska’s Aleutian Islands, mapping over 45,000 square kilometers of previously unexplored seafloor in a bid to address significant gaps in ocean exploration and mapping.

Saildrone, based in Alameda, California, develops and operates a fleet of uncrewed surface vehicles (USVs) equipped with a variety of sensors and instruments to collect ocean data for scientific and commercial applications.

The company on Tuesday said its Saildrone Surveyor, which it describes as the world’s largest uncrewed ocean mapping vehicle, completed the uncrewed survey around the Aleutian Islands and off the coast of California. The months-long survey was part of a multi-agency public-private partnership funded by the National Oceanic and Atmospheric Administration (NOAA) and the Bureau of Ocean Energy Management (BOEM), aimed at addressing ocean exploration gaps in remote areas with USVs.

The US Exclusive Economic Zone (EEZ) is one of the largest in the world, but it is largely still unmapped, unobserved, and unexplored. Alaska, in particular, is the least mapped region of the US EEZ.

The Saildrone Surveyor SD 1200 sailed across the North Pacific to the survey area in July 2022, mapping 16,254 sq km of unknown seafloor around the Aleutian Islands over 52 days. The Surveyor also carried technology from the Monterey Bay Aquarium Research Institute to sample environmental DNA (eDNA), providing crucial insights into marine biodiversity and ocean health.

Despite challenging conditions in the Aleutian region, including 35-knot winds and wave swells over 5 meters, the Surveyor collected high-quality data, which will be used to optimize dive targets during upcoming expeditions on NOAA’s research vessel Okeanos Explorer.

The second half of the mission off the coast of California involved mapping an additional 29,720 square kilometers of the US EEZ and discovering a previously unknown seamount standing approximately 1,000 meters high. Saildrone said identifying such seamounts improves our understanding of the physical processes of the ocean and identifies areas needing further exploration as unique habitats.

The project was operationally managed through NOAA’s Ocean Exploration Cooperative Institute (OECI) and the University of New Hampshire. The data collected around the Aleutian Islands will be publicly available through NOAA’s National Centers for Environmental Information.

Saildrone says its Surveyor class vehicles are increasingly in demand, with an additional four Surveyor-class ocean mapping vehicles to be built by Austal USA in Mobile, AL, this year. The mission proves that long-endurance USVs provide a viable option to achieve the goals of the National Ocean Mapping, Exploration, and Characterization Strategy. This is the future of ocean mapping.
