Tide Gauge Benchmark (TGBM) Description
|93214 B 1994||NOS primary bench mark is at the onshore end of the concrete pier. The bench mark is 0.2 foot below ground level, crimped to a stainless steel rod driven 52.0 feet to refusal and encased in a 6 inch PVC pipe and concrete kickblock.|
- 3214 A 1994
- 3214 C 1994
- 3214 D 1994
- 3214 E 1994
TGBM = 1.982m above mean lower low water (1960-1978 epoch)
TGBM = 1.315m above mean high water (1960-1978 epoch)
The daily or monthly means do not reveal any obvious reference level shifts.
The data for 1996-2000 were supplied with heights relative to MLLW. Consequently 3015mm 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.
