Inhaltsangabe:

Porosity and bulk density were calculated from known volume and weight of sediments before and after drying at 50°C or freeze-drying. Large imprecision of the porosity and density measurements results from an imprecise volume sampling (± 0.5 cm³) with a head-cut syringe. As a result, depth profiles of porosity and density show no visible trend. Results must be carefully interpreted and some outlier values were discarded.
