DO meter needed a significant recalibration upwards. Suspect that it could have been an artifact of being in hot car or similar. Results appear higher than for all other sites, despite most other parameters being very close between sites. At Site H3, DO required calibration back down again.

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.
