Sea Level At Vlissingen Falls Then Rises Around 1890 – As Does CET

Sea levels at Vlissingen in Netherlands from PSMSL show a fall until about 1890 then a rise which mirrors Central England Temperature (CET) record.



cet_v_vlissingenSea levels can appear to fall for a number of reasons among them

  • Local land rise
  • Re positioning tide gauge and failing to account properly for the move

So it’s best not to get too carried away.

Here are sea levels as recorded at Vlissingen and 5 other locations in France, Netherlands and Germany.

Bearing in mind sea levels are supposed to be rising more or less continuously, measurements at all locations show a fall around the same time as Vlissingen (if only slight)


Which is a bit clearer if we zoom in.


PSMSL have a monthly records from Vlissingen from 1862 with no gaps (as far as I can tell).

England has 2 locations with records from 19th century.

Liverpool shows a dip between 1880 and 1900, despite clearly having gaps.


The record from Sheerness is longer than for Liverpool, but seems to consist of gaps more than sea level observations!


If France, Netherlands and Germany can mange to keep long term records of sea level observations WITHOUT GAPS – why can’t the UK.  It would help if UK tide gauges were kept operational, rather than being closed every few decades and a new one installed somewhere else.


If falling temperatures lead to falling sea levels
and if, as some people are predicting temperatures are set to FALL (another little ice age)
then perhaps sea levels will fall

And UK Environment Agency can stop worrying about sea level rises of over 1 metre.
