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.
