Observation details

Overview

Estuary Painkalac Creek Estuary
Site Great Ocean Road Bridge at Aireys Inlet
Observation ID #10891
Date and Time Saturday 11th February 2017 11:00am
Approved Approved

Notes

Due to not being able to calibrate EC, we did not take any EC measurements.

As the rope holding the Van Dorn broke and the Van Dorn was lost on the bottom of the estuary before any measurements could be taken we did not do any measurements at 2.3 m or do Turbidity or pH measurements either.

We also noted that the oxygen went out of calibration very quickly
