AMS - Silt, Sand, and Bottom Dredges
AMS offers a variety of dredges designed for sampling sand and silt as well as most types of non-cohesive material. AMS sampling dredges are placed onto the bottom sediment, then closed and pulled up to retrieve a sample. Careful release of the sample distributes the sample approximately as it appeared on the bottom – making sediment profile description possible. The sample is not suitable for most geotechnical analysis and does not provide samples suitable for high-quality chemical analysis for volatile contaminants.
