Overview

Estuary Hopkins River Estuary

Observation ID #15984
Date and Time Friday 19th January 2024 17:20pm

Notes

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.
