QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated: 20 Nov 2019 Station : Mar del Plata-B Latitude: 38 02.1S Country : Argentina Longitude: 057 31.8W JASL # : 729B Time Meridian: 045W (GMT - 3 hr) GLOSS # : 192 Originator #: 729 NODC #: 53058701 Contributor : University of Hawaii Sea Level Center (UHSLC) 1000 Pope Rd. MSB 317 Honolulu, HI 96822 Originator : UHSLC in collaboration with Servicio de Hidrografia Naval Avda. Montes De Oca 2124 C.P. 1271 Buenos Aires ARGENTINA Original Data: digital Instrmnt Type: 1) 3/2010-7/2015 radar (RAD) gauge (Vega Vegapuls 62) 2) 3/2010-7/2015;10/2016- Handar Encoder 436-A (ENC), float/well 3) 3/2010 - 2nd radar (RA2) Primary channel used in JASL set: 3/2010-2014: ENC 2015 : RA2 2016-2018 : RAD *short gaps in primary channel filled with other channels as available; see UHSLC for specific dates Digitzd Intvl: 2 min RAD, 3 min RA2, 10 min ENC Present Data : Hourly, daily, and monthly values obtained by: Hourly : 3-point Hanning Filter centered on the hour 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 : 24 Mar 2010 - 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 : 2010-2018 Refernce Levl: Heights are referred to the station tide staff zero, which is linked to land-based benchmarks. This reference zero is unique to this station and is not an official datum (chart, national, etc.) and is not relative to local tidal parameters, such as mean lower low water. See the Originators for benchmark descriptions, maps, and the geodetic levelling history. The site was moved in 2010 though benchmarks between the sites have not been linked so the series are separated into 729A and 729B. Comment : The hourly residuals show large fluctuations with 2-4 day periods associated with weather or shelf waves. JASL Nov 2019 update replaces 2016- 05 Sep 2017.
