SternisheFan writes: A self-controlled swimming robot has completed a journey from San Francisco to Australia. The record-breaking 9,000 nautical mile (16,668km) trip took the PacX Wave Glider just over a year to achieve. Liquid Robotics, the US company behind the project, collected data about the Pacific Ocean's temperature, salinity and ecosystem from the drone. The company said its success demonstrated that such technology could "survive the high seas". The robot is called Papa Mau in honour of the late Micronesian navigator Pius "Mau" Piailug, who had a reputation for finding ways to navigate the seas without using traditional equipment. "During Papa Mau's journey, [it] weathered gale-force storms, fended off sharks, spent more than 365 days at sea, skirted around the Great Barrier Reef, and finally battled and surfed the east Australian current to reach his final destination in Hervey Bay, near Bundaberg, Queensland," the company said in a statement. Some of the data it gathered about the abundance of phytoplankton -plant-like organisms that convert carbon dioxide into oxygen and provide food for other sea life -could already be monitored by satellite. However, the company suggested that its equipment offered more detail, providing a useful tool for climate model scientists.
e-credibility: the non-guaranteeable likelihood that the electronic data
you're seeing is genuine rather than somebody's made-up crap.
