This record was made with an Aanderaa current meter. The nominal
speed threshhold of this meter is 1.5 cm/sec, and a common practice
is to set below-threshhold speeds either to the threshhold value
or to half the threshhold. In this case, however, below-threshhold
speeds were set to zero by the originating PI, as were concurrent
directions. In processing historical data we normally reset below-
threshhold Aanderaa speeds to half the threshhold, but have not
done so in this case because the direction information has been
lost.
