Very old pH strips used for pH samples, as pH metre sensor failed

Thanks everyone.  Interesting to see some anoxic water down deep, but quite likely this time of year and given how dry it has been.

tide "pouring out" at mouth

 

Great observation & data; very strong salt-wedge and some potential algal activity in the upper water column already!!  Thanks Jarred.

Results look great - getting a bit saltier with reduced rainfall and streamflow by the looks!  Fantastic effort Fiona, Emily & Harriette - great that you came along & hopefully we'll see you back next month!  Thanks Jarred
