paragraph_text: Northernmost land
  
  The northernmost point of land on Earth was long thought to be Cape Morris Jesup at the northern tip of mainland Greenland. However, in 1969 a Canadian team surveyed Kaffeklubben Island (latitude 83° 39′ 45″ N), which was first recorded in 1900 and first visited in 1921, and determined that its northernmost point is 750 m north of Cape Morris Jesup. It is thus the northernmost undisputed permanent land.
  
  Other points have been claimed to be the northernmost point, with dispute over the title arising from ice sheets, water movement and inundation, and storm activity that may build, shift, or destroy banks of gravelly moraine material. In 1978 Uffe Petersen, a member of the Danish Geodetic Institute, discovered Oodaaq Island at 83° 40' 32.5" N. Its last confirmed sighting was in 1979. In 2003, a small protrusion of rocks and boulders, 35 m × 15 m (115 ft × 49 ft) in length and width, was discovered by Arctic explorer Dennis Schmitt and his team at latitude 83° 42' N and unofficially named 83-42. Whether this land is permanent is uncertain; a 2022 bathymetric survey determined that it was likely not connected to the seafloor, but rather rocky material on top of sea ice, and thus not land.
