=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 16-Jan-2013 :
The Mean Sea Level data values for Leixoes 1890-2009 have been supplied by
Isabel Araujo from CIIMAR of the University of Porto.

The station has been flagged so the data should be used with caution.

The following paper describes the data recovery on the historic records
undertaken by Isabel and her colleagues:
'Analysing the hundred year sea level record of Leixoes, Portugal'

http://dx.doi.org/10.1016/j.jhydrol.2012.12.019

The work was sponsored by the local port authority APDL
The data were analysed from the original paper rolls. From 2001 onwards the sea level heights refer to a different vertical datum. In the above paper a value of 0.326m was used as a correction for this. This offset is included in the data supplied to the PSMSL.
