Undisturbed Benthic Sampling with Multiple Corers (Photo: OSIL) (Photo: OSIL) Traditional benthic samplers such as box corers must be deployed with sufficient momentum to ensure penetration of the seabed. This creates a bow wave that will disrupt the surface layer of the seabed before the corer is able to collect a full sample. The multiple corers available from seabed sampling experts Ocean Scientific International Ltd (OSIL) are able to overcome the traditional difficulties associated with benthic sampling and collect truly undisturbed sediment samples. The multiple corers are landed on the seabed at slow speed which, in combination with the minimal footprint of the corer, prevents a bow wave from forming and driving away the delicate flocculant material that forms on the surface layer of the seabed.
