Underwater robot survives voyage to 'never-accessed region of the planet'

Environment Conservation Ocean Underwater robot survives voyage to'never-accessed region of the planet' An Argo float delivered unprecedented data after eight months beneath Antarctic ice. Breakthroughs, discoveries, and DIY tips sent every weekday. Thanks to an underwater survey robot, oceanographers are getting the first-ever readings collected from underneath East Antarctic's vast ice shelves .
