Larger icebergs weighing up to 1m tonnes have reportedly been towed with a rope slung between two vessels. It makes a nice crackly sound in a glass of water. On average, these icebergs are 60-80 metres wide at the waterline, weighing around 100,000 tonnes, said Tony King, director of ice engineering at C-Core, a Canadian engineering firm that makes equipment for the job. It moves water through special membranes that keep the larger salt molecules from passing through. The industry has come up with nets for capturing unstable icebergs, but they dont work in every case.
