It's midday and Edward Kean, a Canadian fisherman who now scours the North Atlantic for icebergs that have broken off from Greenland's glaciers, is positively beaming.

Every morning at dawn, Kean sails out with three other crew members to hunt what has become his own personal white gold: icebergs.

Kean then hacks the blocks up with an ax and puts the pieces into 1,000-liter containers to melt over the coming days.

In the high season, from May to July, the crew can gather 800,000 liters of water, which they then sell to local merchants for a dollar a liter. Those businesses in turn market the iceberg products as made from some of the purest water money can buy.

Niche marketDyna Pro, one of Kean's clients, sells the water in glass bottles for 16 Canadian dollars ($12) each.

U.S. tourist Melissa Axtman, who has family roots in Newfoundland, says she is "enjoying all the things made out of iceberg water".

But she acknowledges "good things and bad things" about the increasing number of icebergs, a symptom of climate change.
