Station Summary

Station	St. John's
Country	Canada
GLOSS No	223
Latitude	47 34.0N
Longitude	052 42.0W
Time Meridian	053W (GMT -3.5 hr)
Contributor	Marine Environmental Data Service, Dept. of Fisheries and Oceans, S12082-200 Kent St.Ottawa, Ontario, CANADA K1A-0E6
Originator	Dept of Fisheries, Atlantic Tidal Section, BIO, P.O. Box 1006, Dartmouth, Nova Scotia, CANADA B2Y-4A2
Instrument Type	OTT float/well gauge until 1987 when bubbler gauge was installed which utilizes the tidal acquisition telemetry system (TATS)
Original Data	analog (OTT) digital (TATS)
Observational periods	01 November 1961 at 0330 - 01 January 1997 at 0230
Tide Gauge benchmark (TGBM) description	All heights have been referred to the station tide staff zero which is linked to fixed benchmarks. The primary benchmark is BM 76F27, a Geodetic Survey of Canada (GSC) tablet which is located horizontally in the SE foundation, 1.1m from south corner, 0.15m below brick siding of the St. John's Ministry of Transport depot building. Elevation 4.412m above chart datum.

Quality Assessment

The hourly residuals show significant fluctuations within the tidal frequency band. It is not sure whether this is due to the inability of the tidal analysis to resolve the complex nature of the tides or errors in the timing of the instrument. Only extreme fluctuations are listed below.
