The AMS Multi-Stage Sampler (MSS) is an ideal choice for collecting samples up to four feet in thickness. The sampler has four stainless steel 12" sampler body sections (a base section and three sampler body extension sections) to allow field personnel to make a sampler to the length that is needed. The kit comes with three four-foot stainless steel extensions that allow users to deploy the sampler through 12 feet of water before reaching the sediment. Dredges may also be used to collect samples from the upper/top 4 inches of the sludge.
