A harbour employee checks the gauge every day in order to detect any malfunction. Gauge servicing agency By a contractor: Sea & Swell, s.a. 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 No strong currents close to the well. The well also filters adequately the waves outside. Tide gauge benchmark description Name: NGU 84. Located inside the tide house, over the floor, at 40 cm from the wall closest to the sea. Frequency of levelling Only pre-installation levelling in 1992. We are proposing a relevelling for 1999. Tide gauge zero relative to EUVN 2.944 m below EUVN Tide gauge zero relative to 2.455 m below national levelling datum national levelling datum Tide gauge zero relative to Tide gauge zero is 6,306 m below NGU 84 and national levelling datum is 3.851 m below NGU 84 tide gauge benchmark Auxiliary benchmark description NAPH 367 and 6750. Note: there is an uncertainty in the heights of these benchmarks, so it is very important a relevelling here. Permanent GPS within 1 km No EUREF code Campaign GPS Waiting for information from IGN. Geological substrate bedrock Gauge signal likely to The Cubas river mouth is located 1 km in front of the tide gauge station but it is not a large river. During floods due to strong rainfall there is probably an important change in water density inside the bay. be affected by river outflow, density changes etc Any other information No strong currents close to the well. The well also filters adequately the waves outside.
