On descent two levers with buckets at their ends are spread like open scissors that unlock on hitting the seabed. When pulled upwards the two buckets close and grab a sample. This is subject to more disturbance than by Craib or box corers. The double grab configuration allows for more efficient sampling operation. It comes mounted to a purpose-built deck stand and galvanised seabed frame. It has a typical sampling area of approximately 0.2 m2 (10 litre capacity per bucket)."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1535" ; skos:note "accepted"@en ; skos:prefLabel "Ocean Ecology Dual Van Veen Grab"@en ; skos:related , .
