6 Apr 2017

Approved

Notes:

Strong outward current meant observations taken at south end of jetty.

Turbulence around the probes at 0.1m prevented the Hach meter readings from stabilising.

Problems with calibration of pH meter (it would not lock on to pH4). Thus pH indicator strips used instead of pH meter.
