=========================== BENCHMARK INFORMATION UPDATE ADDED 12-JUL-93 :
Ko Lak 600/021 RLR(1981) is 8.4m below BM A
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 01-Jul-2009 :
Although the data for Ko Lak 2008 was supplied directly from
The Hydrographic Dept. of the Royal Thai Navy the missing days
information was erroneous. When queried with them they insisted
that the figures were correct (missing days included 720,95 days)
so figures were obviously wrong. Decision was taken to use the
missing day information for 2008 from the JASL CD.
