A harbour employee checks the gauge every day in order to detect any malfunction. Gauge servicing agency By a contractor: Sea & Swell. Observation periods 6 years Gauge type acoustic Sampling rate 5 minutes Digital data Yes Real time data No Storm surge warning gauge No Additional parameters Any other parameters MSL method Submission to PSMSL No PSMSL data holdings Other data banks Additional information The site is open to wave influence. The quay was built during the 60's. Tide gauge benchmark description Name: SSM. It is located on the floor outside the tide house, on the west corner in front of the door. Frequency of levelling Only preinstallation levelling in 1992. A relevelling is being proposed for 1999. Tide gauge zero relative to EUVN 2.825 m below EUVN Tide gauge zero relative to 2,327 m below national levelling datum national levelling datum Tide gauge zero relative to Tide gauge zero is 5,982 m below SSM and national levelling datum is 3,655 m below SSM. tide gauge benchmark Auxiliary benchmark description NP 615 , NAPG 467 and NGK 793. Permanent GPS within 1 km No EUREF code Campaign GPS Waitinf for information from IGN Geological substrate landfill Gauge signal likely to There is a small river, Monelos river, which flows close to the tide gauge station, but harbour staff don't think this could influence the sea level signal significantly. be affected by river outflow, density changes etc Any other information The site is open to wave influence. The quay was built during the 60's.
