An effective and inexpensive new method of vibracoring has been developed for acquisition of continuous cores up to 13 m long in unconsolidated sediments. This system can be used on land and in water depths up to 18 m. The principal components, a 7 hp. concrete vibrator, drill pipe and liner or thin-walled aluminum irrigation tubing, are stock items. The entire system weighs 150 kg and costs about $2,000. With this system approximately 200 cores averaging 4-6 m in length have been recovered in sediments ranging from clay to coarse sand. Percentage of recovery is usually 90 to 100% and distortion of delicate sedimentary structure is generally minor.
