What are they transporting, Dan? They look like mechanical narwhals, or giant fishing bobbers. (Nice clouds, btw ;-)

While out for a walk at Golden Gardens Park, there was a group preparing a few Seagliders to launch in the Puget Sound. The Seaglider is manufactured by Kongsberg Maritime. The group also referred me to the Applied Physics Lab website at the University of Washington for information regarding the Seagliders.

Seaglider™ is an autonomous underwater vehicle (AUV) or underwater glider developed for continuous, long term measurement of oceanographic parameters. Rather than an electrically driven propeller, the vehicle uses small changes in buoyancy and wings to achieve forward motion. The system's pitch and roll are controlled using adjustable ballast (the vehicle battery).

A interesting technology.
