Pressure records from the instruments on this mooring show that
the mooring slipped downslope several times during the experiment.
For example, during the week beginning 24 Mar 03 the mooring's
depth increased by about 6 meters. On 24 Apr 03 the depth increased
by 2.4 meters. Between 19 May and 21 May it increased by over
6 meters. The total depth change during the experiment was about
24 meters, most of which had occurred by 1 Jun 03.
The velocity data from this instrument are problematical.
Velocities from the shallowest bins (those farthest from the ADP)
resemble random noise, and in fact the signal-to-noise ratio in
these bins is close to zero much of the time. Even the deeper bins
near the ADP seem noisier than one would expect.
The velocities are available here in 28 files, one for each bin.
The bin files contain speed, direction, u, v, vertical velocity and
bin depth. The latter quantity is calculated from the ADP's recorded
roll and pitch, and from blowover as obtained from the accompanying
MicroCat's pressure record. We used the MicroCat pressures rather
than those of the ADP because they are thought to be more accurate.
Please be aware that the bin depth record is quite gappy because
we were unable to use roll and pitch during episodes where the tilt
sensor had reached its limit of about 52 degrees. Thus depth is
unavailable for a few hours during most diurnal tide cycles, when
the current is maximum and the instrument has blown over more than
52 degrees.
The depths shown below with bin statistics should be taken as
no-blowover depths - bin depths when roll and pitch are both zero.
