Abstract

The Atlantic Oceanographic Laboratory's Department of Energy, Mines and Resources, Ottawa, Canada, has announced the development of a new oceanographic tool. The rock-core drill, developed over a four-year period by John Brooke of AOL's mechanical design group, is operated by the department's Marine Sciences Branch; AOL is part of the Bedford Institute at Dartmouth, N. S. Completely automatic, the drill is powered by the pressure of the ocean itself. A timing mechanism opens a valve allowing seawater to flow through a hydraulic power unit into a low-pressure reservoir. Another mechanism regulates the drill pressure on the rock face.
