    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.
