Box corer

It is designed for a minimum of disturbance of the sediment surface by bow wave effects which is important for quantitative investigations of the benthic micro- to macrofauna, geochemical processes, sampling of bottom water or sedimentology.

The surface area of the box ranges between 200 cm2 and a quarter of a square meter (50x50 cm = 2,500 cm2); the penetration depth of 0.5 m can be controlled to prevent over-penetration in softer sediments.

On recovery, the sample can be processed directly through the large access doors or via the removal of the box completely, together with its cutting blade.

The sampling box is made from stainless steel, the cutting blade as well as the corer are galvanised for reduced contamination and corrosion.

Jumars at the Scripps Institution of Oceanography in collaboration with the United States Naval Electronic Laboratory (USNEL) in San Diego[3][4] to determine the faunal composition at the abyssal floor.
