Values replaced with 0.0m since they are within the acceptable range of the instrument. All negative numbers were deleted. These occurred during a real turbidity event, however, I do not know why the instrument logged negative values. Values are suspect but left in. Likely caused by changes in atmospheric pressure.
Drift is likely the cause.
Data were left in but are suspect. Likely caused by changes in atmospheric pressure. All DO data for this time period is suspect. Several negative turbidity values were recorded and the cause could be due to exposure of the probes on several occasions. The following negative depth values were recorded during this month.
