Measurements being at chart datum point Newlyn. Mind you an extra 3 to 4 cm depth as land sinks at high tide wont make much navigational odds getting into tidal harbours. And if 5m tide does that, what does 14m Bristol Tide do?
 
They say it's because of the tides but, in reality, it's part of the process of establishing complete Cornish independance from the UK. Years of accumulated up and down movements will lead to a crack at the border with Devon, the process will be complete and 20,000 Cornish men will be unemployed. :D

It's a very well-known phenomenon. Earth tides are just like sea tides, but much smaller amplitude. Not sure why they pick out Cornwall - they affect the entire solid body of the earth.

I don’t know. So long as the net is still working their hard toil sitting in front of the telly with a laptop in its nominal place, trying to keep us from contacting government departments will continue as usual.

Sorry but I think that's somewhat negative way of looking at the issue. I prefer to view it as London second home owners not being able to get to Cornwall :D Oh and for what it's worth I was born and still live in the Midlands with no association with Cornwall except for the incredible hospitality I used to receive racing Ospreys at Mounts Bay.

Getting to Cornwall doesn’t quite have the romance of the olden days. Then, you left cosy Devon, with its red soil and colourful thatched houses and crossed Bodmin moor to be faced with a land devoid of colour, past the ‘white mountains’ of China clay spoil into this distant place that was so different to everywhere else. My interests were coastal of course, and these ranged from tiny coves to large surfy beaches, and I have always loved bleak remote places ever since.

My earliest memories of going to Cornwall are very, very fragmented. It was some time in the 1950s. I was probably about about 5 or 6. We stayed B&B at a farm. I remember the farmer wanting to take Dad shooting Rabbits. I had a pet Rabbit who I adored and I was in tears at the idea that Dad would go out and kill a Rabbit. Being a kind and loving Dad he didn't go. Many.many decades later I was chatting to my Mom about going seal watching and she told me that when we went on that Cornish holiday all I wanted to do was to go to cliffs and look down at the seals. I don't remember that but given my life long of animals, both domestic and wild, it sounds very much like how I would have behaved. :)

It's already cracked. It's well known that it's only the chains of the Torpoint Ferries that stops Cornwall drifting away.

Yes, back in the late 40's early 50's my dad bought a Ford 8, I believe the 8 was the hp.
With mum, dad, camping gear and us three kids it was a long drive from London, getting a good 30mph down hill.
Thick fog caused a very slow run, a real pea soup'er so dad decided to camp for the night.
He stopped the car and went for a walk around, found a nice grass place to pitch tent, so bounced the car up the kerb and settled in for the night.
Next morning clear blue sky and there we were camped on a roundabout on the (A30?)
 
The entire South East land mass is rising now that the Glaciers have all melted.
At some point the Rubber Dinghy trade will have to find other employment, should eventually be able to just walk across again ?

It is Scotland that is rising most as that was where the greatest glacier depth was. As scotland rises, the seesaw effect makes southern england sink

i expect Yorkshire remains true to form and stays level

Doggerland not expected to resurface soon

The OS datum is at Newlyn.

What impressed me is that they said that GPS satellites can detect a 40mm change in surface height.

They can detect much smaller changes than that, but not in real time - even back in the 1990s, changed of millimetres could be measured. But you have to record signals and post-process them to get that accuracy.
