To commemorate the 400th anniversary of the Mayflower’s transatlantic voyage from England to the US, IBM announced in 2021 an ambitious effort to repeat the journey with the Mayflower Autonomous Ship (MAS) — this time without any people onboard. The plan was to use AI models to make accurate navigation decisions while delivering live data to inform policies for climate change and marine conservation.
A typical ocean research expedition involves as many as 100 scientists and lasts about six weeks. Subtract traveling time and the complexities of navigating weather and rough seas, and that leaves only about a week for actual research. IBM built MAS to help change this dynamic. A solar-powered vessel, it travels independently to remote and dangerous regions. Researchers back on land download live data and images synced to the cloud, such as whale songs or ocean chemistry — detected by an “electronic tongue” called Hypertaste. “With AI-powered sensors onboard, scientists can access more meaningful insights at greater speed,” said IBM researcher Rosie Lickorish, who holds a master’s degree in oceanography. “The cost of data for our experts is low, in time as well as money.”
The AI Captain at the helm of MAS uses a vision-and-radar system, which includes six AI-powered cameras, 30 onboard sensors and 15 edge devices, for precise navigation. The system scans the ocean and uses an operational decision manager (ODM) to avoid collisions. A decision-optimization engine recommends next best actions, and a “watchdog” system detects and fixes problems. Rules-based decision logics in the ODM validate and correct the AI Captain’s actions, and a log tracks exactly which initial conditions were fed into ODM, which makes debugging and analyzing the AI Captain’s behaviors vastly easier than the “black box” AI systems commonly used today. “ODM keeps the AI Captain honest and obeying the ‘rules of the road’,” said Andy Stanford-Clark, IBM Distinguished Engineer and IBM Technical Lead for MAS.
After a 3,500-mile journey over 40 days, MAS successfully arrived in Halifax, Nova Scotia, and IBM declared the mission complete — although data from the journey will undoubtedly continue serving researchers for years to come.
The MAS project garnered considerable attention from the media, generating coverage in the likes of Fortune, Smithsonian magazine, and The Wall Street Journal, and by the BBC. Which shouldn’t be surprising. The wonders and mysteries of the water are alluring — as is a good ocean adventure story.
