QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 02 Dec 2019 Station : Suva-B Latitude: 18 08.0S Country : Fiji Longitude: 178 25.7E JASL # : 018B Time Meridian: 180E (GMT + 12 hr) GLOSS # : 122 Originator #: ID070013 NODC #: 31178801 Contributor : National Tidal Centre, Bureau of Meteorology PO Box 421 Kent Town SA 5071 South Australia AUSTRALIA Originator : same Original Data: digital Instrmnt Type: Aquatrak acoustic (SEAFRAME) Digitzd Intvl: 6 minutes (average of 181 one minute samples) Present Data : Hourly, daily, and monthly values obtained by: Hourly : Cosine-Lanczos filter with cutoff of 120 min. 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 : 27 Jan 1998 - 31 Dec 2018 Gaps > 1 mon : none Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat. Trans. : Yes Distribution : 1998-2018 Refernce Levl: All heights have been referred to the station Tide Gauge Zero (TGZ), which is linked to fixed bench marks. The height datum is Mean Sea Level derived from the Longitudinal Pillar in the 1997 survey. Series 018A is separate from 018B because they are at different locations. Comment : High resolution coordinates: Lat: 18 deg 07 min 57 sec S Lon: 178 deg 25 min 39 sec E The daily and monthly means do not reveal any suspicious reference level changes. Comparison of daily means with Lautoka and satellite altimetry suggest there could be land subsidence at the Suva tide station equating to a slow positive sea level trend.
