current essentially stops immediately, but the deep flow con-
tinues for some time,
It is calculated that when the east northeast trades are
prevailing, water in the lagoon is completely exchanged on the
average every 4O days.
At times of light southerly or scuth-
easterly winds an estimated 60 to 100 days are required.
No
conditions were observed during the field work in which very
ewe
rapid flushing of the lagoon occurred.
