Sediments are an important component of any aquatic system. Sediment sampling is typically conducted at the same time as surface-water sampling because of the obvious physical connection between the two media. However, as is the case with soil samples, there are a number of unique features of sediment samples that must be considered when designing a sediment sampling program. This module discusses how the complexity of sediment samples affects where and how we collect sediment samples. It introduces terminology unique to sediment sampling and describes a number of common objectives of sediment sampling programs. A variety of manually deployed and mechanically deployed devices used for collection of shallow surface sediment grab samples and depth-discrete samples, and the applications and limitations of these devices are discussed in detail. Upon completion of this module, you will understand why sediment sampling is such hard work and why sampling device selection is more involved that choosing something that looks good in a catalog!
