QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 20 Jun 2001 Station : Buenos Aires Latitude: 34 40.0S Country : Argentina Longitude: 058 30.0W JASL # : 285A Time Meridian: 045W (GMT - 3 hr) GLOSS # : none TOGA #: none NODC #: 53054801 Contributor : National Ocean Service/NOAA Originator : Servicio de Hidrografia Naval Avda. Montes De Oca 2124 C.P. 1271 Buenos Aires ARGENTINA Original Data: analog Instrmnt Type: float and stilling well; standard recorder Digitzd Intvl: hourly Present Data : Hourly, daily, and monthly values obtained by: Hourly : spot 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 : 01 Jan 1905 - 31 Dec 1961 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. : No Distribution : 1905-1961 Refernce Levl: The data have been linked to tide staff zero by the originators. Site location at the south entrance to the harbor. The reference level is 100 cm below Lowest Low Water, 463 cm below the Tide Datum, 511 cm below Mean Low, 542 cm below Mean River, 573 below Mean High, and 907 cm below Highest High. Comment : The residuals contain large fluctuations with periods of 14-72 hours. These fluctuations are due to the inability of the tidal analysis routines to resolve the many nonlinear harmonic components of the shallow water/river environment. The daily series show the noisy "weather" signal. Only extreme fluctuations with periods in the semi- and diurnal tide frequency band are noted below.
