This bright yellow autonomous boat might be the key to unlocking the ocean's secrets. Built by researchers at the University of New Hampshire, the Bathymetric Explorer and Navigator is more affectionately called BEN.
The self-driving boat is used to map the ocean floor, and can assist crews in finding long-lost wrecks, like the famous Ohio in Lake Huron, as The Verge reported. BEN has been involved in other recent searches, and mapping the ocean floor can help improve understanding of the ocean and climate in other ways, too.
Autonomous surface vehicles like BEN are used to gather data that divers and ships with crews can't reach.
It sends information back to the control room in the trailer on shore.
BEN is bright yellow, and about 13 feet long. It can travel for about 16 hours before needing to refuel.
In August, BEN set out to find answers to the disappearance of pilot Amelia Earhart in 1937.
The first woman to fly solo over the Atlantic, Amelia Earhart sent her last radio signals from somewhere over the Pacific in 1937 during an attempted world flight.
BEN and the research vessel EV Nautilus went out to look for information on the ocean floor that might give insight about what happened to Earhart.
BEN was lowered into the water near the tiny island Nikumaroro in the South Pacific, about halfway between New Guinea and Hawaii.
Mapping the ocean floor is expensive and labor intensive, and scientists estimate we've only mapped 9% of the total area.
Equipment on BEN will collect data to create 3D topographic maps of the ocean floor.
Scientists think better knowledge of the ocean floor could help us understand climate change, improve safety at sea, and make it easier to create deep sea cables.
The crew of the Nautilus will use that data to target dives and hopefully find evidence from Earhart's flight.
A National Geographic camera crew accompanied the expedition this summer...
...and took some of these stunning photos of BEN off the coast of Nikumaroro. The crew searched for two weeks, but didn't find evidence of Earhart's plane.
BEN has been on other research expeditions, too.
These photos are from a mission in Pago Pago Harbor in American Samoa.
BEN was also used in Lake Huron's Thunder Bay, sometimes called "Shipwreck Alley" for its history of disastrous wrecks.
