We analyzed the Nd ICs and REE concentrations of unfiltered samples in most cases.
Some surface and bottom samples were filtered using 0.45 µm filter. The analytical
procedures are described in Lacan and Jeandel, 2001. The reproducibility of the Nd IC
measurement was 0.5 εNd unit, blank values were 700 pg (3.5% of the most depleted sample
and 2% on average). Reproducibility of the REE concentration measurements was better than
10% for the whole REE and better than 5% for Nd, blanks values were better than 8% for the
whole REE and better than 3% for Nd. Results are reported in Table 1.
3. Denmark Strait Overflow Waters (DSOW)
3.1 East Greenland Current
The DSOW are the densest waters overflowing the Denmark Strait. Their origins are the
topic of numerous studies and still unclear. Among the remaining hypotheses, most of the
recent publications suggest that the precursors of the DSOW are carried within the EGC from
the north of the Nordic Seas (Strass et al., 1993; Mauritzen, 1996; Rudels et al., 1999a).
During the Signature/GINS campaign, the DSOW had the following hydrological
characteristics: -0.5
