Sortable silt data was obtained from core MD03-2673 located in the North Atlantic. The sediment was analysed with a laser diffractometer at Bio-Indicateurs Actuels et Fossiles (BIAF) lab, in order to provide informations on past changes in intensity of the Iceland-Scotland Overflow Water (ISOW) over the Marine Isotopic Stages 7 and 9. The original sortable silt data (percent and mean) were used for comparison with the new method of correcting for ice-rafted debris (IRD) influence on sortable silt described in Stevenard et al. (submitted).

The study was supported by the CNRS-INSU LEFE D.E.C.O.R.A.T.I.N.G project: "Dynamique des principaux courants profonds de l'Atlantique lors des périodes chaudes du passé : étude des interglaciaires des derniers 450 000 ans".
