Approximately 32.8% of the speeds were at or below the instrument's
stall speed, which is 0.8 cm/sec. These speeds have been recorded
as 0.8 cm/sec.

There are problems with direction in this file. The PI notes:
"The compass in this instrument, or possibly the vane, appears to
have been unable to swing freely for extended periods during which
it could report a direction only about 300 degrees magnetic, notably
during 2005 days 115-145, 2005 days 255-285, and after 2006 day 045.
Otherwise, there were almost no really good periods of apparent
vertical coherence of current to allow comparison of compass
directions from different instruments, especially this shallow.
An attempt to find agreement with the compass in RCM-7 1315 at
600m during one short, possible comparison period found discouraging
disagreement in the only quadrants with any samples. This may reflect
the extremely weak horizontal magnetic field."
