Pressure inceases by about 3 db during the first several hours.
Some deeper instruments show the same increase. This may indicate
that the mooring slid deeper, or that the pressure sensors became
acclimated slowly. Conductivity shows a similar initial increase,
by about one mmho/cm. This appears to be a sensor problem rather
than a depth increase, since it it unlikely that conductivity
would change that much over 3 meters of depth.
