Ocean drones plumb new depths

Ocean researchers are turning to gliders, or winged and propellerless drone, like miniature Tomahawk missiles. Two are on loan from the Navy, and one, is pockmarked from a past shark attack.

As they slink into the Atlantic to begin a month-long mission, they join a fleet of 12 others across the Eastern Seaboard, from Nova Scotia to Georgia.

The drones are the centerpiece of “Gliderpalooza,” a collaborative ocean-survey experiment coordinated by 16 American and Canadian government agencies and research teams.
