A convenient, portable, hand-operated surface-sediment sampler for use in shallow water is described. Collection of replicable, undisturbed surface sediment samples from shallow-water locations is made simple. The sampler is highly portable for use at remote sites and can be operated by one person. It is especially useful for sampling in the 0.3–1.3 m water depth range where other samplers are often unsuccessful. This sampler consists of a PVC tube (about 33-cm length, 7.1-cm diameter) attached to a 1-m-long supporting rod. A lever system is used to close off the PVC core tube. In the open position, the core tube is inserted into the sediment to an optimal depth (typically 1-cm) so that a 1-cm disc of surface sediment is enclosed. This disc is then isolated by operating the lever and tube closure plate. The sampler and sediment sample (with an intact epipelon biofilm) are removed carefully so that most of the enclosed water drains away and the sample is retained intact.
