flows north-eastward along the east Greenland Coast following a coastal counter current.
Coastal counter currents are particularly subject to terrigeneous matter inputs, but the absence
of any concentration increase or Precambrian influence on the ε Nd value precludes this
possibility. Therefore, AW likely comes from the Irminger Current and crosses the strait. The
flow in the Denmark Strait being in a very large majority southwestward orientated, a limb of
the Irminger Current crossing the whole strait uninterruptedly is hardly imaginable. Moreover
the absence of AW at station West suggests that its transportation is due to discontinuous
structures. One has therefore to invoke a small dimension structure (at the strait scale), which
is able to cross the strait without being entrained by the EGC. It is therefore probable that the
AW found at the mouth of the Nansen Fjord crossed the strait within eddies. Eddy formations
in the Denmark Strait have been described in several papers (Krauss and Käse, 1998; Spall
and Price, 1998).
