Reference Level

Additional Information
The Munro tide gauge in a stone building, at the corner of the Quay D, was dismantled in the early 1970's. The Zero of the recorder corresponds to a marked level situated seven feet below the level of the Quay. This datum point denotes the level of the mean low water at spring tides. It was selected in 1929 after taking the average of the low water spring tide levels over a 48 month period.

Comment
The daily or monthly means do not reveal any obvious reference level changes or trends.
Data for 1942-1947 were received from two originators. The difference in daily values between the series was steady with a mean value of 3040 mm. Thus 3040 mm was added to each value of the Proudman data and then the data sets were merged.
