Before 1978 values based on readings of high and low waters
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 06-AUG-92 :
Italian levels may be influenced by the Messina earthquake of 1908 - See Bottari et al., Tectonophysics 202, 269-275, 1992
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 17-MAR-93 :
The stations Porto Maurizio (250/001), Napoli Arsenale (250/041) and Napoli Mandraccio (250/051) appear to each have a datum shift around 1910. Evidence for regional coherence?

=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 2000Jan25 :
Genova              250/011 RLR(1963) is 10.2m below BM
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 22-Jan-2016 :
A value of MTL-MSL=-2 mm has been applied to the RLR data for the period 1884-1977.  This value was derived by Philip Woodworth in preparation of his MTL/MSL manuscript.  In this case the values were derived using from the GESLA2 (high-frequency tide gauge) dataset using harmonic constituents.
