At  Ling’  Bank  the  tidal  currents  absolutely  predominated,  though 
some  re  sul  ting  current  may  be  traced.  From  Figure  7 we  see  the 
average  displacement  of  the  masses  of  water  at  the  different  depths 
during  the  course  of  a whole  tidal  period.  At  2 meters  there  was 
a resulting  current  going  eastward.  At  75  meters  the  movement 
was  more  northerly,  towards  E NE.  In  the  intervening  depths 
we  had  comparatively  even  transitions.  The  displacement  seems  to 
have  been  greatest  at  10  meters,  but  the  average  velocities  for  the
