Relative Marine Question, this time!!!!

Aidan · 10 March 2007, 23:26

Hello People!

Does anyone of you geographic majors happen to know the following hypothetical question:
If all theice caps and Glaciers melted, what level above chart Datum would the water rise assuming the Air held no more than normal.

Just need to know at what level do I build my next house.
I am sure if it rises a meter or two you can say goodbye to New York, Pakistan, alot o China as the Big rivers fill,
Is there any easily accesible working module that we can puta height into and se whats left...
Would such an extra weight trigger off Earthquakes....
Time to earn your crust Boffins, show that all that study was worth our while as tax payers whilst you were doing your masters on the back end of the lesser spotted blood sucking twin lanced mosquitoe

Floating ice will make no difference at all - it's just the land based ice masses that will cause the problem. Think of an ice cube in a glass of water - if it melts the water won't spill out of the glass.

good article on it on wiki

Noise!

Aidan is on the bottle again.

Thanks LL and Mollers too,
Yep on the sauce again/

However, I have seen something on this in the past that if all the Ice melted using Scientific evaluation, the level would only rise some 18 inches.

Seeing that I happen to own a property on a water front that is posibly some 5 feet above the normal sea levls, I get occasionally concerned, especially in westerly gales in Spring Tide.
Its not that I am overly concerned (nor perhaps will I be alive ) by the time that it happens but once the media start into it, it may interfere with my pension.

Other than that mollers (remember punk, as in the music, not you!) noise to some is money to others,,,ME!

As it happens,
and having researched this question, I have got answers from a few feet to 80 meters, obviously there is a few different answers out there.

So I dont know If I will need wellies or a Deep Sea Recovery Sub to get to work.
That was the bones of my question, still no one seems to know.

Rebuild your house where it is, but use screw-pile foundations. That way your house doesn't need to be on the ground at all, and if the sea does rise, you can simply lift it up and add extra height to the piles! A decent step-ladder and bob's your uncle!

Couldn't you just use a trolly jack, and some wedges?

Yes, but that wouldn't keep me in a job!

Just use a styrofoam foundation. Float it back to shore should you find your house has gone mobile. Make sure you use adequate scope when anchoring, though...

Just buy a bigger rib, who needs a house?

Wasn't there a company in the south USA somewhere actually doing this? Building houses on a bouyant slab, towing them down-river and then anchoring them in place?
