NB. The probe cover was accidentally left on the probe when the profile was recorded, so we made a second set of readings with the cover off, and recorded these on a second data sheet, labelled H2_2. The figures entered above are the correct readings.

Both sheets will be uploaded

*No worries, thanks for picking this up a retesting, J.Obst.

The YSI meter somehow went into a mode where it would only display integers for the D.O. % Sat. Managed to correct the problem at the next site (H1).

No worries - thanks for heads up, this won't cause any issues with the data set.  Great to hear you were able to correct the problem.  Very strong salt-wedge too; autumn swells on display!!  J.Obst.
