The Aanderaa pressure gauge at Ibiza has been replaced by a new MIROS radar sensor. Both new and old gauges were running for the period 24.09.2009-18.10.2010 for inter-comparison purposes during which a malfunction of the old sensor was detected. A bias (mean difference) of -0.81cm between the two gauges was calculated. See paper by B. Perez et al 'Overlapping sea level time series measured using different technologies: an example from the REDMAR Spanish network'.

Further investigation revealed that the bias was due to a problem in the old pressure gauge. Data from this was revised. Complete dataset re-entered onto database.
