Comments

No new vertical shift is discoverd when new data for 2019 were added. For this reason previously corrected record for 2010-11-01T18:44:55 to 2018-12-31T00:22:00 was extended with new data for 2019 and processed. Previously 3 segments with different vertical mean tidal levels were estimated: 1. 2010-11-01T18:44:55 to 2011-08-30T03:07:54 with estimated tidal mean level of 4.7420 m, 2. 2011-08-30T03:08:24 to 2012-01-15T06:18:45 with estimated tidal mean level of 5.3209 m, 3. 2012-11-05T21:09:00 to 2018-12-31T00:22:00 with estimated tidal mean level of 1.9713 m. Segments 1 and 2 are shifted downward by -2.7706 m and -3.3495 m respectively to the mean tidal level of segment 3 which is considered to be the "base" one.
