Comments
The daily or monthly means do not reveal any obvious reference level shifts.
Residuals are extremely noisy and large fluctuations are possibly attributed to the passage of high and low pressure cells across the South coast of Australia. Since 1991, atmospheric pressure has been measured at the tide gauge site.
