Maximum pitch and roll

When vertical profilers and gliders start their profile, there may be considerable pitching and rolling of the vehicle before it settles into a more consistent flight. Thus, these parameters can also be used to exclude regions that produce poor data. There are no hard criterion for pitching and rolling. In quiesent water, the principal axis of a vertical profilers typically pitch and roll about [math]\displaystyle{ 1\, ^{\circ} }[/math] about their mean values. In waters that are vigorously turbulent, the large eddies may make a vertical profiler pitch and roll by about [math]\displaystyle{ 5\, ^{\circ} }[/math] .
