The counting intervals span a core depth range of 545–3190 cm, corresponding to an age range of 16–42 ka cal BP (calculated based on the age-depth model from Andrzejewski et al. (submitted) and Lebeaupin et al. (submitted). IRD were counted in the ≥150 µm fraction obtained after wet sieving and subsequent drying. Grains identified as minerals and terrigenous debris were considered as IRD, but biogenic silica and foraminifera were excluded. IRD were quantitatively counted under a binocular microscope. IRD counts are presented as the number of grains per gram of dry bulk sediment (#IRD/g). This approach provides a first-order estimate of IRD input to the MD07-3119 site. -76.099833333333 -76.099833333333 -46.083166666667 -46.083166666667 -76.099833333333 -46.083166666667 2007-02-21T11:29:00 2007-02-21T11:29:00 5.4 32.5 vertical profile MD07-3119 -46.083166666667 -76.099833333333 -2523.0 2007-02-21T11:29:00 MD159 IMAGES XV - Pachiderme 2007-02-06T00:00:00 2007-02-28T00:00:00 Marion Dufresne (1995) https://en.wikipedia.org/wiki/Marion_Dufresne_(1994) FNIN 9050814 Kissel, Catherine Marion Dufresne (1995) https://en.wikipedia.org/wiki/Marion_Dufresne_(1994) FNIN 9050814 Calypso Corer II CALYPSO2 32.54 m 271 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ This dataset has been carefully reviewed and curated in accordance with PANGAEA's exceptionally high quality standards.
