Vibrocoring is an effective method for obtaining samples from thick sediment deposits. Vibrocoring produces a relatively undisturbed core with sufficient volume to satisfy the needs of almost any combination of laboratory analyses. The vibrocoring system is a model P-3c manufactured by Rossfelder Corporation of Ponway, California. The vibrocoring unit is submersible, weighs 150 pounds, and is powered by a three phase, 240-volt 60Hz generator. For the core tube the Water Survey system utilizes a 10-foot section of schedule 5 black iron pipe with a diameter of 4inches and lined with a HDPE liner. Cores can be split horizontally and processed for chemical and biological characteristics.
The vibrocore rig consists of an 18’ tetrapod structure mounted on a 23’ pontoon boat.
A winch/cable system is utilized for raising and lowering the vibrohead through a moonpool in the deck of the pontoon boat.
