    The box corer is a marine geological sampling tool for soft sediments in lakes or oceans. It is deployed from a research vessel with a wire and suitable for any water depth. It is designed for a minimum of disturbance of the sediment surface by bow wave effects which is important for quantitative

    How do the corers work?
    The Corers are easily deployed from a deck stand and can be lowered onto a standard lifeboat no-load release, which activates after sediment penetration. The box is closed, top and bottom, by two closely fitting shovels, mounted on pivot arms. Removable weights allow the corers to be used successfully in a range of sediment types.

    What is the weight of the stem of the corer?
    The stem has a weight of up to 800 kg to aid penetration. While pulling the corer out of the sediment a spade swings underneath the sample to prevent loss. When hauled back on board, the spade is under the box.

    How do you deploy a box corer?
    To deploy the box corer an "A"-frame or a sliding beam with at least 3 m clearance is required. The corer is lowered vertically until it impacts with the seabed. At this point the instrument is triggered by a trip as the main coring stem passes through its frame.

    The Box Corers are simple and reliable corers for sampling an areas of 0.05m2 (Mini), 0.1m2 (Standard), 0.25m2 (Mega) or 0.5m2 (Giant) of sediment with minimal disturbance and sample contamination. Its unique double shovel design allows easy access to the sediment for sub-sampling for subsequent scientific investigation.
