How much Fresh Water is locked up

[ashling]

in the ice shelf that broke off in Canada and from the Ross shelf in Antarctica?

First, a disclaimer: I realize that this might be dumb, stupid, environmentally unsound, etc. I am just posting this thought for discussion.

Assuming that Global Warming has gone so far as to doom these or other geographical ice features, and that if the melt, which they surely will given the original assumption, this would dump a lot of fresh water into the seas disruptin salinity and ecosystems, and given the fact that there are large areas of the earth without sufficient fresh water, would it be feasible, and or too environmentally disruptive to try to "mine" these features for their water reserves to be distributed elsewhere?

Discussion???

I am cross posting this for wider comment.
