We measured all sediment samples with a grain-size analyses to investigate changes in particle size distribution through the whole stratigraphy. It turns out that (sandy) medium to coarse silt is the omnipresent mean fraction, although the (silty) fine sand content is increased in several layers of the upper (0.00–0.73 m) profile section.
