A new ROV storage device for deep-sea sampling.

Sampling deep-sea biota is a significant challenge because of the logistics required, in terms of vessels and equipment, to obtain minimally preserved specimens. Traditional methods (trawls, nets, and dredges) cause physical damage, stress, and even contamination during the process of removal from the seabed and their displacement through the water column to the surface. Preserving conditions similar to those found in situ is particularly important when the sampling strives to maintain living organisms and for analyses where contamination or degradation by stress or damage may interfere with the results.
