Azul, I wish I had seen that show, blowing up icebergs sounds really cool ! I suppose one could use a torpedo to blow up an iceberg, especially today's torpedos which carry incredibly powerful warheads, some are even tipped with nuclear weapons. The only reason I can think of is the fact that dynamite is relatively inexpensive compared to the cost of a torpedo, which might cost more than a million dollars apiece. So my answer is : Either way would work , but one way is cheaper and less complicated.
