Benchmark Relationships
TGBM = 8.73 feet above mean lower low water (1960-1978 epoch)
TGBM = 7.81 feet above mean sea level (1960-1978 epoch)
TGBM = 7.18 feet above mean high water (1960-1978 epoch)
Quality Assessment
Comments
The daily or monthly means do not reveal any obvious reference level shifts.
The data for 1997-2000 were supplied with heights relative to MLLW. Consequently 1320mm was added to refer the data to tide gauge zero.
The data for 1998-2000 were supplied in non-GMT format and had to be shifted into GMT.
