A Lightweight Pneumatic Coring Device: Design and Field Test.

Abstract

A lightweight pneumatic coring device for use from relatively small research vessels was developed and field tested. The device consists of an aluminum frame supporting a core barrel surmounted by a pneumatic industrial vibrator. Tests of a number of paired ball-type and piston-type vibrators revealed that a poston-type vibrator with a 3-inch-diameter piston provided the best penetration and was capable of obtaining cores from 0.6 to 2.4 meters long from a variety of unconsolidated sediments. A description of the tests and drawings of the final design are presented. (Author)
