There are some unusual and abrupt direction shifts in this record,
from about 330 degrees to about 90 degrees. This behavior occupies
only a small fraction of the total length of the file, but does
occur on several occasions throughout the record. The direction
series from some other instruments on the mooring behave similarly
at approximately the same times, which suggests that the sudden
veering is genuine. 

Approximately 28% of the speeds in this record were below the
current meter's threshold and have been set to 0.01 cm/sec. (The
speeds were set to a nonzero value so that direction information
would be preserved in u and v. For the most part, current records
in this component of ACM-8 contain u and v but not speed or direction.
Hence, in order to preserve direction without expicitly including
a time series of directions, BSH has elected to represent below-
threshold speeds as 0.01 cm/sec, encoded in u and v. This is true
for all the current records in the German portion of ACM-8.)
