This year, rather than just sending the latest year of data the complete dataset has been supplied. This has highlighted some differences in the data. From communications in the correspondence file for 2002 it appears that the Oceans and Fisheries meant to supply revised data for the stations supplied. This did not happen. The complete dataset includes these data revisions. Therefore, the whole dataset has now been re-entered.
The tide gauge at Port Alfred has now been removed.

Documentation added 2019-06-18

Station Port Alfred was re-installed in mid July 2017 due to some external pressure and the fact that it is a reference port in the Canadian Tide Tables. The new station has been levelled to the previous benchmarks.
