=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 2002Sep24 :
A description of the sea level network in Finland can be found
in 'Operational Oceanography: Implementation at the European
and Regional scales. 2002 (pp.129-137)'.
1879-1903 VALUES BASED ON 1 READING PER DAY
1904-1970 VALUES BASED ON 6 READINGS PER DAY
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 11-JUN-91 :
Helsinki 060/351 RLR(1964) is 9.6m below BM7HB
=========================== BENCHMARK INFORMATION UPDATE ADDED 12-JUL-93 :
Helsinki 060/351 RLR(1964) is 9.6m below BM7HB
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 03-Jan-2012 :
Levelling information recently supplied by the Finnish Meteorological Institute
confirms Primary benchmark remains 7HB 4.48m above gauge datum of 1904 onwards.
Previous datum for 1879-1903 was 1.967m above the present datum.
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 31-Jan-2017 :
Following the 2016 levelling exercise some adjustments have been made to the benchmark reference heights - at Helsinki this was +1mm for BM 7HB. The adjustments are a result of more accurate measuring and calculations using the N2000 height system. The RLR diagram has been re-drawn because of this.
