Seafaring Robot Sails Through Sandy Unscathed

Very cool! Her explained position puts her roughly in The Hudson Canyon in 2,000-6,000+ feet of depth to the sea floor. This would have put her in very large swells with modest breaking waves on the faces perhaps up to 20 feet (the breakers, not the swells!) so I am not surprised she survived, especially with a keel (the "winged sub") which should keep her from tumbling topsy turvy within a breaking wave if she were caught on a closing face. The getting caught within the closing tube of a crashing wave is what causes the most violent, turbulent shear damage to creTure and inanimate object. I have been out there tuna fishing in 50 knot winds and very lumpy seas, but I will take being out over The Continental Shelf's deep canyon waters than the 250-300 foot shallows just inshore where wave heights immediately climb to much larger breaking seas. More of the autonomous devices will be a great boon to learning about our mysterious ocean world. Bravo to Liquid Robotics!

I second your thoughts. Especially feel the force of a crashing wave when I was a kid surfing :-)

Excellent exposition.

Submariner knew, that even a few 10 meters down the wave action is not violent anymore. Congratulation to the vehicle proving , that staying below the interface is safe.

Good!
