Notes:
Also on the team Fiona Spruzen and Emily Horwill for this sampling trip pH meter couldn't be calibrated so we used pH test strips |

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 |

Notes:
Van Dorn sampler forgotten so pH and turbidity levels not available - No worries, easy done! Based on the EC readings it looks like we've got a WQ profile almost entirely of seawater anyway!! Thanks Jarred. |

Jarred - thanks everyone, great results which indicate a changing season!! Great to see the return of the salt wedge, and although still very seasonally high the turbidity readings are on the way down! |

#15141 | 18 Nov 2022 | Approved |
Notes:
Probe and Van Doorn horizontal in water because of rapid flow, so lower depths not tested or sampled.
Thanks Brad & Dina, and yes no worries regarding the flow and challenges sampling at depth. Very well mixed profile so this alleviates any issues. Very high turbidity remains! Thanks Jarred. |

#15072 | 14 Oct 2022 | Approved |
Notes:
River flowing very quickly; all samples taken with ropes at significant angulation due to flow. High level floods upstream High tide 20.00
Great work everyone & appreciate you making the correct call to not sampling H2 due to flooding risks. Perfect timing regarding the flood peak on the Hopkins estuary (3am the following morning at 1.82m AHD), with a highly turbid, fresh and well mixed profile. Amazing mouth scouring/widening too!! |

Notes:
Bottom pH is <9. Med- Fast flowing out to sea. Mouth photos attached here.
Thanks Brad. Very interesting to see quite a lot of tidal/ocean influence still pushing up the estuary, however this may disappear soon! Great D.O. profile throughout. |

Great results everyone; strong salt wedge down low as expected and highly oxygenated and turbid freshwater in the top water column. J.Obst. |

Great data everyone. Distinct salt wedge due to recent swells/tides and only moderate flow to date. Excellent DO throughout which is great. J.Obst. |
