Gravity Corer
Our integrated coring solutions cover the full range of seabed sampling needs. While our standard Gravity Corer is valued for its simplicity and reliability in obtaining columnar samples, the Piston Gravity Corer represents a definitive advancement for critical applications. Its active piston mechanism counteracts internal friction and prevents plugging, delivering longer, less disturbed cores with superior stratigraphic preservation in soft sediments.
Supported by a versatile deployment platform for heavy equipment and complemented by a selection of compact corers, our product line forms a complete system—from routine surveys to precision research—all customizable to your specific mission requirements.
