Sediment Sampling
SEDIMENT SAMPLING
We offer boat-deployed solutions for surface sediment and core sampling, and specialized diver-operated tools for use in areas with limited access areas or in substrates where boat-based methods are undesireable.
Vibracore Sampling can be an efficient way to collect marine sediments to moderate depths of penetration. Our Rossfelder system utilizes stainless steel barrels and butyrate liners
The core processing liners are clear, allowing visual evaluation of the core in the field. They are left intact and full-length for transport to the processing area.
Our 0.2 square-meter surface sediment grab is used to collect large-volume surface samples. A pneumatic ram closes the grab around challenging debris and substrate.
The Power Grab yields approximately 2.5 gallons from the top ten centimeters, with adjustable penetration up to 35 cm.
RSS divers assist the sediment team at AMEC Foster Wheeler with deployment of their proprietary coring tool, a pneumatic linear hammer that drives a square tube.
During the drive, RSS divers take several internal and external measurements, allowing the MudMole team to plot recovery over the entire core.
Our diver-operated hand cores collect a surface sample from the top 10 or 35 cm. The 10 cm sampler yields 3 liters of sediment.
The large diameter means there virtually no compaction. Stratification is preserved and fines are retained.
This sampler combines the liner and core nose from our 4-inch vibracore with a driving head powered manually by a slide hammer, and yields remarkable recovery.
Since the sediment is never liquefied, and because percent-recovery is so high, this sampling method is ideal for radioisotope analysis.
