Three or four inch diameter cores can be collected continuously to a depth of about 40 feet. Sediment vibracores are used extensively for:
- Contaminant characterization
- Geotechnical characterization
- Geophysical data ground-truthing
- Mineral deposit characterization
- Archeological investigation
Barrel liners are typically flexible food-grade polyethylene for contaminant evaluations or rigid polycarbonate for geotechnical samples or high-resolution environmental cores. The flexible liners can be slit with a razor knife, allowing for easy processing in the field or in the lab. A standard 4-inch diameter sediment core yields about 0.5 gallons of sediment per foot of recovered core. A vessel-based field crew can typically collect 8-12 short cores (<8 feet), 6-10 medium cores (8-12 feet) or 4-8 long cores (>12 feet) a day, depending on sampling conditions. We can deploy multiple vibracoring field teams simultaneously.
