=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 11-Jun-1991
Kalamai 290/021 RLR(1978) is 9.5m below BM 220
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 11-Mar-1997
The contributing authority advises that anomalous values are the result of met. influences
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 20-Oct-2010
Following the revised way of recording the height of sea level at this station to recording upwards rather than downwards there is now an anomaly with the datum. Although the values of TGZ have been questioned several times the HNHS are adament they are correct.Because of this the station was flagged and reverted from RLR status to 'Metric' from June 2002 onwwards. However the station retains the RLR status so that the good RLR data is available on the database.
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 13-Jul-2011
Following further information received from the Hellenic Navy Oceanographic Service the datum problem now seems to be resolved. The plotted data now appears correct. Therefore the station flag has been removed and all of the data reinstated as RLR.
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 07-Aug-2013
Datum diagrams have been received from the Hellenic Navy. With these the RLR diagram has been redrawn. As a consequence the RLR factors have changed.
