Water very clear.

Should take the remote sampler to B2 and B5.

As you can see, today's data collection reflects we are still in learning mode.

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.

It was difficult to collect a bottom sample without disturbing the algae and sediment. This had contributed to a high bottom turbidity reading.
