Best fit to data (blue line). Reference gradient (red lines):-8.6ms/day/mbar.
Going varies with pressure because of drag, added mass and buoyancy. Barometric compensator fitted 28 March 2010 should fix this.

- Barometric compensator: Why does the compensator appear to be working for rapid changes in pressure (ie over a few hours) eg [link] [link] but not for slow changes in pressure (over a few days) eg [link] [link] A real mystery. Perhaps there is a link between pressure and temperature, or maybe updraughts?
