Volcano mapping

A one-armed protractor, used for laying out ship tracks,  rests on top of a map of the 'Rumble III' volcano, located in the Kermadec arc, north northeast of New Zealand. In March 2009, the University of Washington's student cruise aboard R/V Thomas Thompson explored the Kermadec volcanic arc. Marine geologist Dan Fornari was on the cruise to work with the students to map the Kermadecs with TowCam. Fornari showed students how to plan TowCam deployments and plot TowCam survey lines on large-scale maps during the tows, so that the photographic observations could be used to map the seafloor terrains.
