=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 28-AUG-96 :
For discussions of MSL changes and extreme sea levels around Namibia and South Africa, see: G.B.Brundrit, S.Afr.J.Mar.Sci.,16,9-17,1995 and S.Searson and G.B.Brundrit, S.Afr.J.of Science, 91,579-588,1995. 1957 1960 values based on 8 readings a day
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 11-JUN-91 :
Port Elizabeth 430/088 RLR(1985) is 9.4m below BM
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 24-Jul-2006 :
Data for 2000 were supplied by BODC. The values were supplied to BODC via the University of Cape Town and so are not being classed as official.
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 07-Aug-2006 :
Following the recent supply of data from the South African Hydrographic Office the data values for the year 2000 have now been revised with the official values.
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 24-Sep-2009 :
Heights of chart datum relative to land levelling
datum LLD(MSL)in South Africa and Namibia: Port Elizabeth
Datum: up to 31st Dec 1978 = -0.838
Datum: 1st Jan 1979 - 31st Dec 1997 = -0.900
Datum: 1st Jan 1998 - 31st Dec 2002 = -1.026
Datum: 1st Jan 2003 onwards = -0.836
Datum is now LAT so unlikely to change. Benchmark PE 1 has been added to the RLR diagram as this is the benchmark referred to in the GLOSS Handbook.
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 11-May-2010 :
There appears to be a spike in Nov/Dec 2002. This is possbly real as it appears in several of the S. African stations.
