| Additional information | |
| Other relevant information | Munro tide gauge in a stone building, corner of Quay D, dismantled in early 1970s. Zero of 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 and was selected in 1929 after taking the average of the low water spring tide levels over a 48 month period. Local levellings are undertaken at intervals of 6 months. |
