Fig.  3-30:  Trajectory  of  a  Norwegian  profiling  Argo-float  drifting  about  the  transition  zone  towards ­
  the  North  Atlantic.  Marked  positions  are  about  10  days  apart  in  time  and  refer  to  the
profiles  recorded  during  ascents  from  Aug,  13  to  Dec,  1  2003  (cf.  Fig.  3-32).  FIC  and  FSC  denote ­
  British  CTD  stations  in  the  Fair-Isle  Current  and  Faroe-Shetland  Channel  (cf.  Fig.  3-31).
