https://www.pangaea.de/ information publisher tableDigital IRD content is commonly assessed by weighing the detrital particles of the >125µm or > 1mm sieve fractions or by counting the IRD particles of the latter. 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. completed Wang, Yiyun
