I was told long ago that the sea level rises 1cm (above the calculated

centre of 950mb would only cause a 50cm rise in sea levels. Compare

that to the 3-6 metre rises that the moon can manage. Yes, the earth's

crust is far denser than the waters of the ocean, but that does not

mean it is immune to the variations in gravitational force imposed on

it every 24 hours by our neighbouring celestial body.



The causeway connecting Holy Island to the mainland always takes longer

to drain at low tide when the air pressure is significantly low. Of

course this may also have something to do with the often accompanying

strong winds which keep a fresh supply of sea water flowing over it!

I'm a bit bemused by someone being "too dead"! My dad used to say that the fish took better when the pressure was high.
