about 2000 km from the Faroe Bank Channel sill
it reaches the complex region of the CGFZ and
threads its way through the two east–west transform valleys.
The topographic complexity of the region is such
that the author elected to place the transport array
within both valleys at its western end (Saunders,
1994). Here the overflow is seen as a salinity maximum (c. 34.98) with a potential temperature of
about 2.9°C but now occupying the deeper levels
of 1600 m to 3500 m. The mean transport determined was 2.4 <0.5 Sv (Table 5.6.3) and shows
