Instruments

Alvin tube core

Supplied Description:

Instrument Type

Generic Name: Alvin tube core

Acronym: Tube Core

Generic Description:

A plastic tube, about 40 cm (16 inches) long, is pushed into the sediment by Alvin's manipulator arm to collect a sediment core.

Multi Corer

Supplied Description:

Ocean Instruments MultiCorer

Instrument Type

Generic Name: Multi Corer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/51/

Generic Description:

The Multi Corer is a benthic coring device used to collect multiple, simultaneous, undisturbed sediment/water samples from the seafloor. Multiple coring tubes with varying sampling capacity depending on tube dimensions are mounted in a frame designed to sample the deep ocean seafloor. For more information, see Barnett et al. (1984) in Oceanologica Acta, 7, pp. 399-408.
