Interesting notes:
2 Mar 2011: As the Horba U-10 water tester was lowered through the water column, the salinity increased slightly with depth, and the dissolved oxygen dropped from 6.31 mg/L to 2.5 mg/L by about 5m depth. The turbidity stayed low, suggesting that the occasional underlying dinoflagellate bloom that sometimes occurs in the Port waterways was not present at this time.
