deliberate. The argument we develop below, in the remainder of this paper,
is that the time-dependence of deep ventilation at all three of these sites -
Greenland Sea, Labrador Sea and Sargasso - is semi-synchronous, [though
of differing sign], and that the reason for this concerted behaviour has to do
