Hi everyone, Great data set with a very distinct salt-wedge!

Moorhens, Pacific black ducks, Chestnut teals.

 

Great results everyone, thanks for this recent monitoring.  June rainfall has definitely impacted the water quality - in a good way - with the profile now well mixed with highly oxygenated freshwater.  More of this to come if the months ahead I think!  Thanks Jarred.

Australian coot, Pacific black duck, Chestnut teal, White ibis.

 

Great bird observations once again & interesting (yet explainable) dataset with the low DOs in the deeper salt water layer.  This is seasonally typical however and we should see this flush out soon with the winter rains potentially upon us.  Thanks Jarred.

Little black cormorants, White ibis, Little pied cormorants, Chestnut teal, Pacific black duck.

 

Thanks guys.  Data looks great for this time of year, particularly D.O. both above and below the salt-wedge, especially with the lack of rain we've had over the past 5 months (the lower salt layer can naturally become anoxic under these conditions).  Cheers Jarred.

Data looks great, with a very prominent salt-wedge!  Thanks to Karen and the SWTafe students for testing; and thanks Gary for entering this data.  Cheers Jarred.

This sampling took place from fishing pontoon 100m upstream of Stanley Street Bridge due to demolition of bridge. New bridge to be in place September 2022.

 

Royal spoonbills, White ibis, Pacific black duck and ducklings, Little pied cormorant, White faced herons.

 

J.Obst - great water quality and bird observations!  Very distinct salt wedge on the bottom layer which is interesting - shown through Salinity/EC as expected, but also low turbidity down deep due to the clearer nature of sea water vs cloudier freshwater.  Great work!
