The VIC 3500 is a light duty system that can drive to a depth of 200 feet and collect cores to 8 feet in length. The VIC system uses an electric motor to produce up to 3500 ft/lbs of impact force at a frequency of 1500 vibrations per minute (VPM). This system is ideal for use off a small vessel or for shallow water sampling.
Dimensions: 20 in x 20 in x 15 in
Weight: 125 lbs
Core tube diameter: 3 or 4 inch tubes or custom to customer specifications
Vibracoring is a technology and a technique for collecting core samples of underwater sediments and wetland soils. The attached core tube is driven into sediment by the force of gravity, enhanced by vibration energy. The vibrations cause a thin layer of material to mobilize along the inner and outer tube wall, reducing friction and easing penetration into the substrate. The liquid spaces in the matrix allow sediment grains to be displaced by the vibrating tube. Vibracoring works best on unconsolidated, heterogeneous sediments and soils.
All Ocean Instruments Vibracore systems include a proprietary control system to adjust the force output frequency of the vibrohead. Our Vibracorer systems can also be provided with Ocean Instruments SMRT unit providing real-time depth monitoring and optional video and CTD outputs.
