2δ DeuteriumδD‰ SMOWWaelbroeck, ClaireDeuterium values have been measured on ice samples of length comprised between 0.5 and 2 m and reinterpolated on 1 m intervals afterwards. The total ice recovery for each core increment is 85% or higher. Measurement accuarcy is of ±0.5 %o SMOW (1 sigma). From the surface down to 7 m a constant value of -438 %o is reported.
3Sea surface temperature, annual meanSST (1-12)°CJouzel, JeanThe temperature change corresponds to the corrected curve published in Jouzel et al, 1996. This temperature is calculated using a deuterium/temperature gradient of 9%o/°C after accounting for the isotopic change of sea-water and applying a smoothing procedure; this record is then corrected for the influence of the geographical position of the precipitation site as described in Jouzel et al, 1996.
4Dust volumeDust vol10-9 cm3/gWaelbroeck, ClaireDust voulme concentration of ice as published by Petit et al, 1990 from 125 to 2202 m and by Jouzel et al, 1993 between 2202 and 2541 m.
5Dust particlesDust partarbitrary unitsWaelbroeck, ClaireNumber of dust particles larger than 0.8 µm per g of ice. As for deuterium measurements 3.41 m have been added to the depth measured in the field for 5G samples (on this core measurements have been done below 2500 m only).
