Notes:
Strong tidal flow impeded measurements. Van Dorn could not settle to bottom. Numerous attempts made to trigger release on Van Dorn. Samples collected were not accurate for depth indications. We neglected to record D.O.Sat. |

Notes:
Extremely low tide exposed more sand than we had seen previously opposite the jetty. A warning had been issued to boats to avoid trying to get out through the Heads. |

Notes:
Top and bottom sampling was less than 9. (I was unable to enter 'less than' or <) I am not sure which HACH meter was used. |

#11058 | 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. Time of low tide: 12:39
