QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 22 Apr 2015 Station : St. John's-A Latitude: 47 34.0N Country : Canada Longitude: 052 42.0W JASL # : 276A Time Meridian: 053W (GMT-3.5 hr) GLOSS # : 223 Originator #: 00905 NODC #: 74057201 Contributor : Marine Environmental Data Service Dept. of Fisheries and Oceans S12082-200 Kent St. Ottawa, Ontario CANADA K1A-OE6 Originator : Dept. of Fisheries Atlantic Tidal Section BIO, P.O. Box 1006 Dartmouth, N.S. CANADA B2Y 4A2 Original Data: analog (OTT); digital (TATS) Instrmnt Type: OTT float until 1987 when bubbler gauge was installed which utilizes the tidal acquisition telemetry system (TATS) Digitzd Intvl: hourly (OTT); 15 min (TATS) Present Data : Hourly, daily, and monthly values obtained by: Hourly : spot hourly Daily : 119-point convolution filter (Bloomfield, 1976) centered on noon applied to the hourly data with respective periods of the 95, 50, and 5% amplitude points at 124.0, 60.2, and 40.2 hours Monthly: Simple average of all daily values; calculated if 7 or fewer days are missing Span of data : 02 Aug 1935 - 02 Sep 1989 Gaps > 1 mon : 01 Mar 1936 - 31 Mar 1936;01 Oct 1937 - 31 Jan 1942 01 Sep 1942 - 31 Jan 1957;02 Jun 1960 - 13 Aug 1960 27 Aug 1960 - 01 Dec 1960;01 May 1984 - 19 Oct 1984 22 Jan 1987 - 02 Mar 1987 Time Refernce: 053W (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat. Trans. : No Distribution : 1935-1989 Refernce Levl: 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 CD. Comment : This data set is maintained in the local time zone (GMT-3.5 hours). After 02 Sep 1989 a new series, St. John's-B, is established relative to the same datum but with the time zone relative to GMT, since 15-minute data were available for performing this time zone shift.
