QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL Station : Enewetok-A Latitude: 11 25.8N Country : Republic of Marshall Is. Longitude: 162 23.2E JASL # : 006A Time Meridian: 165E (GMT + 11 hr) GLOSS # : none TOGA #: none NODC #: 11161201 Contributor : Scripps Institute of Oceanography University of California at San Diego La Jolla, California Originator : unconfirmed Original Data: unconfirmed Instrmnt Type: unconfirmed Digitzd Intvl: unconfirmed Present Data : Hourly, daily, and monthly values obtained by: Hourly : unconfirmed 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 : 23 Apr 1951 - 31 Dec 1971 Gaps > 1 mon : 17 Jun 1953 - 17 Aug 1953;14 Sep 1963 - 31 Oct 1963 17 Apr 1968 - 17 May 1968 Time Refernce: GMT (hours 00-23) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : No Operational : No Sat. Trans. : No Distribution : 1951-1971 Refernce Levl: All heights have been referred to the station tide staff zero which is linked to fixed bench marks Comment : The daily and monthly means reveal no apparent changes in the reference level. Timing accuracy was no better than +/- 15 minutes as seen in the large fluctuations in the hourly residuals. This series is distinguished from Enewetok-B because the data have not been linked to a common datum.
