Observation details

Overview

Estuary Hopkins River Estuary
Site Site four (Jubilee Park)
Observation ID #15021
Date and Time Saturday 17th September 2022 10:55am
Approved Approved

Notes

The multi-parameter meter was found turned off just prior to taking obs at this site (last of 4) - I turned back on and continued without re-calibrating. 

(I started with a full set of calibrations completed)

 

No worries Brad, thanks for flagging this, but happy to report this shouldn't be an issue.  The YSI is a very stable unit and turning on/off between sites isn't an issue - and most importantly results look spot on.  Very different profile compared to the lower estuary - very fresh, turbid and well mixed!  Great work getting out today, partiuclarly given the weather...  Cheers Jarred
