What is Vibracoring? Find out in under a minute. Watch as our 32ft folding-wing pontoon vessel the R/V Edison is deployed to collect up to 20ft sediment cores with plenty of space for processing the collected sediment samples on deck.
Sediment vibracoring is a cost-effective method for collecting undisturbed, continuous sediment cores—typically 3–4 inches in diameter—to depths of up to about 20 feet. A vibrating head drives a barrel equipped with soft (flexible food-grade polyethylene) or hard (rigid polycarbonate) liners into the seabed or lakebed, minimizing disturbance and preserving the sediment’s structure.
Each 4-inch core yields roughly 0.5 gallons of material per foot, enabling crews to efficiently gather multiple short, medium, or long cores for contaminant, geotechnical, geophysical, mineralogical, or archaeological studies.
