 Length & Distance Calculator It's Big! It's Thick! It's Huge! Greenland has the only permanent ice sheet in the Arctic. Covering about 80% of the world's largest island, it is the largest ice mass in the Northern Hemisphere (Map). Its BIG: The ice sheet extends 1,570 miles / 2,530 km north to south, and has a maximum width of 680 miles / 1,094 km. Its THICK: Average ice thickness is about 5,000 feet / 1,500 meters, but the northern dome had a depth of up to 11,000 feet / 3,400 meters. Its HUGE: This huge mass of ice makes up about 1/8th of the total global ice-mass, and contains about 12% of the world's glacial ice. If it melted, the sea level world-wide would rise 23 feet / 7 meters. As large as it is, the Greenland ice sheet is only about 1/8 the size of the Antarctic ice sheet.
