An underwater robot, named "Redwing", has departed from Massachusetts on a 5-year mission to circle the globe.
The torpedo-shaped glider will measure water depth, temperature, and salinity, and send data back to Massachusetts scientists in near-real time. It will also carry a device to detect tagged fish in the open ocean, which could shed light on migration patterns of marine animals.
"The most exciting for us is to prove that you can send an autonomous vehicle almost anywhere you want under the ocean,"
Leslie Ann McGee, chief innovation officer at Woods Hole Oceanographic Institution, said the technology could be most useful for studying under-sampled areas, like the Southern Ocean.
If successful, the five-year journey could open new opportunities for long-term ocean research.
