The DriX — an unmanned, robotic boat being tested in Alaska this summer by NOAA — could transform work ranging from stock assessments for fisheries to marine mapping.
The marine drone DriX was tested in Puget Sound, but this summer will mark the first time it launches from the research vessel Oscar Dyson in the Gulf of Alaska.
“It’s probably about two and a half feet wide total, about 24 feet long, and it’s powered by a diesel engine,” said Alex De Robertis, a biologist with NOAA Fisheries. Scientists can then combine that data with data from trawl surveys to get a better picture of the midwater column, where fish like pollock are typically found. “The basic idea here is that the ship and the robot are going to be side by side working in the same area,” said De Robertis. “The robot is going to make half the acoustic measurements and the ship is going to trawl where it sees fish and where the robot sees fish.
