Abstract

We developed and improved methods to extrude sediment out of core tubes and to cut defined layers of sediment in the field. For extrusion we use standard connectable 50-cm sewage tubes or aluminum rods with two lines of holes vertically in equidistance of 0.5 or 1 cm. A stopper at the bottom of the core tube is placed on top of the extruder and the core tube is pushed downwards and stopped by distance pins in the holes. The extruder is independent of the length and diameter of the core tube. A modification of the extrusion equipment can be used for checking lamination of the sediment in the field. In addition, a rubber stopper is described for the extrusion of sandy sediment out of the core tube. A PVC-core cutter is presented that is also capable of sampling watery sediments, and it prevents contamination with metal. The advantages of these devices are the simplicity, handling, robustness and cost efficiency.
