Here we present these three sedimentological records together with the correctly measured, but numerically rather erratic magnetic susceptibility record of the IRD > 1mm fraction. The spiky character of sieved IRD susceptibility displays the stochastic nature of large IRD particle deposition. Systematic variations in IRD coarseness (calculated as ratio of IRD > 1mm and IRD >125µm) and bulk sediment porosity suggest considerable grain size variability of the glaciomarine Sediment fraction, while bulk particle density is almost constant at values of 2.7-2.8 g/cm³.
