Notes:
EC checked, but calibration not required.
Initial readings for DO at 0.1m, were unexpectedly different from those at 0.5m, considering the water was very turbulent. We repeated the readings at 0.1m in triplicate,and decided to eliminate the initial readings (outliers) and averaged the later three readings.
Raw data is recorded on the reverse side of the data sheet.

Notes:
EC checked, but calibration not required.
It was difficult to collect a bottom sample without disturbing the algae and sediment. This had contributed to a high bottom turbidity reading.

At depth of 0.1m, the EC was estimated as the meter reading did not stabilise within a reasonable time.
