Documentation added 1991-06-11

Kalamai 290/021 RLR(1978) is 9.5m below BM 220

Documentation added 1997-03-11

The contributing authority advises that anomalous values are the result of met. influences

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.

Documentation added 2011-07-13

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.

Documentation added 2013-08-07

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.
