Rocky Mountain Soil Sampling uses a Rossfelder Underwater Electrical Vibracorer. Working from Plan B, this system can be used in water over 100 feet deep to collect continuous core samples.
Cores barrels are three- or four-inch diameter and can be up to twenty feet long depending on your application. Several choices in core barrel materials are available including Stainless Steel and Aluminum as well as clear plastic core liners.
The Rocky Mountain Vibracorer uses Contra-rotating Dual-eccentrics and High-frequency vibrations of 8,000 VPM and is ideally suited for sampling the unconsolidated sediments of a marine environment. Power is from a small generator with waterproof cables and extraction by means of a small winch or crane system.
