This video was recording during one of Wally the Benthic Crawler's early test crawls on 21 October 2009. Wally was deployed in September 2009 to a cold seep site in one of Barkley Canyon's gas hydrate fields. The worlds first Internet-operated deep-sea crawler is equipped with sensors to measure temperature, pressure, water currents, salinity, methane and turbidity. Wally also sports a pan/tilt webcam, affording detailed views of the seafloor sediments and local sea life. The crawler was designed and built by scientists at Jacobs University in Bremen Germany.
