Ocean drones plumb new depths

Publish date:

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.
