Engineering360: "Freshwater sourced offshore: Wave-powered desalination"

If ice bergs could be steered in an efficient manner,the fresh water would be worth billions of $. I know this is not currently practical,but icebergs are surrounded by fresh melt water.Perhaps this fresh water could be recovered by using floating suction lines,deployed like a giant spider web form around the berg,with density transmitters connected to suction tubes and cycling the valves according to the density.Perhaps some tubes even attached to the 'berg below the surface in a channel,like an upside down gutter to catch the melt water as it rises.I realize that the 'bergs will eventually flip,but sensors could detect an imminent flip and take defensive measures.

What would happen if controlled charges were planted in the iceberg,like with surface mining,where they pulverize many tons of material in a few seconds,but positioned in a manner to "cut" the iceberg?Would the ice absorb the heat and reduce the explosive power as it transitioned from ice to water,to steam( 3 phase latent heat transition)?

What if shrapnel of some specific shape was in the charge to increase the power of the charge,like a giant ice pick?
