Sediment Core Extrusion Method at Millimeter Resolution Using a Calibrated, Threaded-rod

An extrusion method using a calibrated threaded-rod is presented, which allows for mm scale subsampling of aquatic sediment cores. Millimeter-scale sampling is necessary to fully characterize recent event stratigraphy in sediment records.
