Bottom pH and turbidity values not available as sampler forgotten

 

Great results again - amazing how far upstream the seawater can penetrate!

Oxygen levels at 0.5 metres double checked and values as noted.  JObst - no worreis, quite a plausible DO value, most likely due to a mid-water algal bloom producing excess DO.  Thanks for noting this & double checking - great QAQC!!

Great results everyone, thanks for your efforts!

Possibly one of the most consistent WQ profiles I've seen through the entire system for some time, hence confirming the flushing/resetting of water quality profile from an extended and high magnitude flood event!  It will be very interesting to see what the summer months bring & how long it takes turbidity to settle down.  Cheers Jarred.

Instruments moving with flow of water

 

Great data everyone - incredible turbidity readings!!

Also - i can't see a inflow estimate on the data sheet & was wondering if this needs to be updated to 'Fast' given the flood event?  Thanks Jarred.

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
