QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 18 Oct 2019 Station : Honiara-B, Guadalcanal Latitude: 09 25.3S Country : Solomon Islands Longitude: 159 57.3E JASL # : 009B Time Meridian: 165E (GMT + 11 hr) GLOSS # : 066 Originator #: ID070011 NODC #: 30159901 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 gauge (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 : 28 Jul 1994 - 31 Dec 2018 Gaps > 1 mon : 01 Jul 1997 - 08 Sep 1997;27 Oct 2017 - 15 Jan 2018 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : Yes Operational : Yes Sat. Trans. : Yes Distribution : 1994-2018 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 FBM1 in the 1994 survey. Height of Seaframe Sensor Bench Mark (SSBM) above TGZ is 4.266m. Series 009A is separate from 009B because they are at different locations. Comment : At some time in the future, a single series from 009A and 009B will be created. At present, use of data for the years of overlap are at the discretion of the data users. High resolution coordinates are: Lat: 09 deg 25 min 18 sec S Lon: 159 deg 57 min 19 sec E The daily and monthly means reveal no apparent changes in the reference level and agree with Funafuti.
