Chambers and incubators
Deep-sea benthic chamber (6000 m)	Chambers for studying exchange rates over the sediment-water interface are normally manufactured in POM or coated titanium.  Stirring devices creating calibrated flow regimes over the sediment surface are manufactured with a feed-back check of the stirring rate.  Water sub-sampling within and outside the chamber at discrete time intervals are optional, as is an hydraulically driven shovel for recovery of the incubated sediment core.
