83-42 is the name for a small patch of rock, above sea level, located in the Arctic Ocean, which if confirmed may be the northernmost permanent point of land on Earth. It is also sometimes referred to as Eklipse 0 or Schmitt’s Island, after its discoverer, Dennis Schmitt.
It is 35 by 15 metres (115 by 49 ft) in length and width, and it lies at Coordinates: , which is 699.8 kilometres (434.8 mi) from the North Pole. Discovered in 1998, it is 4 metres (13 ft) high, and lichens were found growing on it, suggesting it was not one of the temporary gravel bars commonly found in that region.
The island was discovered on 6 July 2003 by an American expedition. This expedition was led by Dennis Schmitt and Frank Landsberger. Based on the latitude, the expedition members who discovered the body gave it the unofficial name 83-42. The island is also called Schmitt's Iceland. To be recognized as land area it is required that the area permanently rises out of the water, even at high tide. Given its very small size is doubtful whether 83-42 has this property. According to its discoverer 83-42 is composed of rocks and boulders, a relatively resistant material, and is not just a fleeting sand and gravel bank. The height of about four meters above the water surface could indicate that 83-42 is a permanent island is given the weak tidal effect in the Arctic Ocean. As of November 2007, however, the island was not recognized as land area.
If Schmitt's Island (83-42) is granted the status of land area, it is the northernmost land area of the earth, because it is closer to the North Pole by 2.8 kilometers than ATOW1996. Since the classification of a land area as an island is not dependent on the size of the land area, 83-42 would be, if recognized as a land area, also the most northerly island in the world. In most geography books Kaffeklubben Island is still listed as the northernmost land point.
Another island, RTOW2001, although located 960 meters closer to the North Pole than ATOW1996, is not currently recognized as a permanent land area. Moreover RTOW2001 is about 1.8 kilometers further from the North Pole than 83-42 and would therefore not constitute the most northerly land. Oodaaq, at , is another semi-permanent gravel bank claimed as northernmost.
All of these small islands, with the possible exception of 83-42, are not permanent. Waves and ice floes shift gravel banks around in these shallow waters. The northernmost permanent land, according to established science, is Kaffeklubben Island, at.
