Did not take other measurements at 2.2 as too difficult to determine this depth without attachment on Van Doorn and so close to 2.0 metres.

#10891 11 Feb 2017 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
