Submission + - A Fleet of Sailing Robots Sets Out to Quantify the Oceans (bloomberg.com)

pacopico writes: A start-up in California called Saildrone has built a fleet of robotic sailboats that are gathering tons of data about the oceans. The saildrones rely on a hard, carbon-fiber sail to catch wind and solar panels to power all of their electronics and sensors. From a Businessweek story, "Each drone carries at least $100,000 of electronics, batteries, and related gear. Devices near the tip of the sail measure wind speed and direction, sunlight, air temperature and pressure, and humidity. Across the top of the drone’s body, other electronics track wave height and period, carbon dioxide levels, and the strength of the Earth’s magnetic field. Underwater, sensors monitor currents, dissolved oxygen levels, and water temperature, acidity, and salinity. Sonars and other acoustic instruments try to identify animal life." So far, they've been used to find sharks, monitor fisheries, check on climate change and provide weather forecasts. Saildrone just raised $90 million to build a fleet of 1,000 drones, which it thinks will be enough to measure all of the world's oceans.
