MAFF notes that at deployment the ship's echo sounder gave a
bottom depth of 2706 m. The meter was positioned 19m above the
bottom, so its depth was 2687 m which corresponds to a pressure
of 2731 db. However, the minimum pressure recorded in situ by
the meter was 2684 db. This discrepancy may be explained by
inaccuracy of the ship's sounder, but may also be due to the
lack of an applicable calibration for the current meter's
pressure sensor (see below).

Regular calibrations were not available for this meter's
pressure and conductivity sensors. Pressures were calculated
with coefficients derived for a similar sensor fitted to a
different meter. Conductivity coefficients were determined
by inserting resistance loops into the cell aperture, a bath
calibration not being available.

CMDAC has prepared an alternate version of this file in which
a few direction spikes and speed spikes, apparently caused by
instrument errors, have been smoothed by linear interpolation.
Both the original version of the file and the alternate version
are available at this site.
