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.Corresponds to Figure 3.-49.23483333333342.8395SE Grand Banks SlopeGerman Research Foundationhttps://doi.org/10.13039/501100001659221211316GRK/IRTG 1904: ArcTrain - Processes and impacts of climate change in the North Atlantic Ocean and the Canadian ArcticPetroleum Technology Development Fundhttps://doi.org/10.13039/501100009614Shettima BukarOverseas postgraduate scholarship to Shettima Bukar
