Instruments

Multi Corer

Supplied Name: WHIMP Multi Corer

Supplied Description:

The Woods Hole Interstitial Marine Probe (WHIMP; Martin and Sayles, 1996) was specially designed for in situ porewater sampling. The WHIMP is equipped with an in situ whole-core squeezer (Bender et al., 1987; Sayles and Dickinson, 1991) for high resolution sampling near the sediment-water interface. It is a 'lander' system of the 'Smith type' that differs from its predecessors primarily in that it incorporates a number of different sampling and analysis strategies onto a single platform. The designers of the WHIMP sampling system wanted to be able to carry out sediment and pore water studies, direct flux measurements with chambers, and conduct in-situ experiments at the same place and time. It includes a syringe to extract water samples at various depths, ranging from less than an inch to two feet. References:

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.
