“Andre Rossfelder was a fascinating man. When I watch our field techs using one of Andre Rossfelder’s vibracore units, I think about some of the James Bond-like stories Andre told me about his youth, including his attempts to assassinate Charles De Gaulle.
Whenever we deploy our inflatable Rossfelder barge, it’s amazing to think that Jacque Cousteau’s son Phillipe used to go bombing around the South Pacific with it tucked away in Cousteau’s seaplane, the Flying Calypso.” — Ken Hayes
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.
