The Autonomous Saildrone Surveyor Preps for Its Sea Voyage

If you happen to be crossing the San Francisco Bay or Golden Gate bridges this week, look for a massive surfboard with a red sail on top cruising slowly across the water. Don't flinch if you don't see anyone on board. It's actually an autonomous research vessel known as the Saildrone Surveyor and it's being steered remotely from shore. The 72-foot-long vessel is launching this week into the bay from its dock at a former naval base in Alameda, California. It is designed to spend months at sea mapping the seafloor with powerful sonar devices, while simultaneously scanning the ocean surface for genetic material to identify fish and other marine organisms swimming below.
