Multitube Corers

A multitube corer is used for studying meiofauna (small benthic fauna measuring between 32 µm and 1 mm) and microfauna (bacteria).

Using an array of plastic tubes it takes samples of undisturbed surface sediment to a depth of approximately 300 mm. Its maximum dive depth is 5000 m.

The corer comprises an array of tubes which slides within a frame that sits on the sea floor.
