Since glaciers calve and icebergs split, why can’t one be moved by, say , tug boats or barges to be mined as a source of fresh water?

Answer 1

Towing the iceberg to the destination would be a very slow process, as 90% of the thing is underwater, and the drag would be considerable. Once there, you’d have to have some sort of drydock for it, and the deep draft of the berg would make the drydock very expensive to engineer and build.
