For those who can get here in summer, these waters provide a feast of epic 1 proportions. But the good times will be very short, a problem that faces all life in the Polar Regions.
Journeying the south across the Arctic Ocean, the first land you/ reach is Greenland, the largest island in the world. Despite its name, Greenland is mostly white, covered by a giant ice sheet, six times the size of the United Kingdom.
In the middle of the island, the ice is nearly two miles thick. It's a bleak 2, quiet world. Sapphire-blue melt lakes are the first sign that a dynamic process is underway. Each lake forms in a matter of days, expanding until it's miles across and starts to overflow 3
The spill water then carves its way/ through the ice. The water crosses through an icy delta 4 like blood along the arteries 5 of a cold bloody 6 monster, a monster that is stirring.
And without warning, the water suddenly plunges 7 down an open shaft 8, falling a vertical 9 mile into the heart of the ice sheet.
This melt water has a surprising effect. It lubricates the junction 10 between the ice and the rock floor beneath, so the entire ice sheet is now on the move, sliding downhill into the ocean.
