Oodaaq

Oodaaq lies at 83°40′N 30°40′W, only 705 km (438 mi) south of the North Pole and 1,360 m (4,460 ft) north of Kaffeklubben Island, lying near the northeast tip of Greenland. When discovered it measured a mere 15 by 8 m (49 by 26 ft).

It was discovered in 1978 when a Danish survey team led by Uffe Petersen landed a helicopter on Kaffeklubben Island to confirm that it did indeed lie further north than the tip of Greenland. Having confirmed the fact, a member of the team spotted a dark spot 1,300 m (4,300 ft) northeast of Kaffeklubben Island. The survey team landed on Oodaaq Island in a helicopter and later named it Oodaaq after the Inuk who accompanied Robert Peary on his journey to the North Pole.

Gravel banks such as this are generally considered not to qualify for the title of world's most northerly point of land as they are rarely permanent. In fact several subsequent expeditions have claimed that Oodaaq has now disappeared beneath the ocean.

A number of other locations have since been called the northernmost point. In July 2001, the Return to the Top of the World Expedition came to the conclusion that the previously-discovered island and permanent land feature ATOW1996 is the northernmost point of land on earth.[1]

In July 1998, Peter Skafte photographed, during an aerial reconnaissance, a small island farther north than any previously observed. During July 2003, Peter Skafte, Mara Boland and Dennis Schmitt, plus three other people walked out over the melting sea ice to the new island. It is located about three kilometres (two miles) north of Kaffeklubben Island, at about 83°42'N. Snow and ice had melted to reveal a 35 m (115 ft) bank of rocks and sand at a height of about 4 m (13 ft). Later Ken Zerbst failed to locate the island in 2008 while using a helicopter.

There are several possible explanations for the failure to locate the island in 2008.

• The island may not be a permanent land feature connected to the bottom of the sea.

• Seasonal and yearly accumulation of snow and ice has rendered the island invisible.

• The island was discovered in a belt of multiyear fast ice, but global warming has eroded this layer of ice along the Greenland coast. Perhaps the island has been exposed to the force of the drift ice and has been 'bulldozed' away.

• The GPS coordinates for the island's location are most likely inaccurate. GPS satellites are low on the horizon near the North Pole, which may cause a GPS to yield inaccurate results.

In late 2004, the Eighth Edition of the National Geographic World Atlas was released. It clearly shows Oodaaq as the northernmost landmass on Earth.

In August 2005 and 2006, Dr. Peter Skafte, Allen Deforest (satellite engineer), and Dr. Paul Lommen (physicist) conducted a search for new islands north of Greenland, using high-resolution satellite images.

Two sets of images were obtained, one year apart, to determine if any of the new islands had moved. One island was 64 m (210 ft) in diameter and visible on a satellite image, even without magnification. The team named it "Skafte Island" and posted it on a website. They also sent two reports about their findings to Hauge Anderson at the Danish Polar Center. One report in 2005 and another in 2006. Dennis Schmitt was shown an image of "Skafte Island" before his departure with a group of people to North Greenland in 2007. He visited the island and made the claim that he had discovered a new northernmost island.
