ABSTRACT (Continue en reverse side if meceaeary and identify by block number) 
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 piston-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.
