The sediments were photographed and described (Appendix 2). Sediment colors were identified according to the “Munsell Soil Color Chart”; we recovered 12 sediment layers based on colour, consistence, texture, structure, grain size composition (a correlation scheme of sediment layers is presented in Fig. C4-2): 1) Dark olive sandy mud with gravel and dropstones; 1a) Dark olive gray sandy mud; 1b) Olive gray sandy mud; 1c) Olive brown sandy mud; 2) Dark olive gray sand (oxidation); 3) Olive sandy silt (bioturbation); 4) Olive silty clay; 4a) Olive silty clay with black points of hydrotroilite (bioturbated); 4b) Dark olive gray silty clay; 4c) Olive brown silty clay laminated (oxidation); 5) Dark olive clay. - 243 -

Deep-sea sediments were often described as ranging from clay to silty clay. They are homogenous and very soft. The colors have often a dark olive to olive brown touch. The sediments are mostly rare of ice-rafted material, also turbidite like deposits of well sorted, coarse grained sand are interbedded. A remarkable amount of ice-rafted material and rock fragments up to 3-10 cm in diameter (mostly metamorphic rock and sandstones) were found in upper 20 cm on the West off Spitsbergen continental margin. The dropstones are mostly rounded. The sediment have sandy silt and sandy mud composition with gravel and dropstones, which indicate the nearly glaciogenic transport by sea-ice and iceberg. The sediment mostly has a olive brown color, indicating oxygenated bottom waters. In the upper 2 cm abundant benthic and planktic foraminifers were observed indicating seasonally open-water conditions and moderate surface water productivity. - 244 -
