Mar del Plata Canyon: underwater robot live stream draws over a million viewers per day

A robot is navigating the cold depths of the South Atlantic seabed, streaming images of dazzling coral and previously unseen fish, while scientists provide live commentary on YouTube – and Argentines are captivated. The scientific mission is for the first time exploring the Mar del Plata canyon, a submarine gorge which plunges nearly 4,000 meters (13,000 feet) deep. The live stream began a week ago and exceeded one million views per day since Thursday.
