is a contentious issue due to variation of definition. How permanent some of the contenders are makes hard determination difficult, but sets an important threshold. Problematic issues include ice sheet
In glaciology, an ice sheet, also known as a continental glacier, is a mass of glacier, glacial ice that covers surrounding terrain and is greater than . The only current ice sheets are the Antarctic ice sheet and the Greenland ice sheet. Ice s ...

material, and observational difficulties due to remoteness. However, a bathymetric survey in 2022 confirmed that certain previous contenders, such as 83-42, Qeqertaq Avannarleq, and ATOW1996Jancik, John; Richardson, Javana; & Gardiner, Steve (2002). Under the Midnight Sun: The Ascent of John Denver Peak and the Search for the Northernmost Point of Land on Earth. are not permanent islands/landmasses, as they are not connected to the seabed, and are only gravel banks floating on an ice sheet.
The following table sets out the main contenders (or previous contenders) for this title.
Currently, Kaffeklubben Island is the northernmost, undisputed land that permanently remains above water. However, due to the ever-shrinking Arctic ice, there could be more discoveries in the near future.
In addition, the Gakkel Ridge has been showing some volcanic activities in recent decades, so a new landmass could form even further north from a future eruption.
In 2022, a Swiss-Danish expedition visited the area, to confirm the existence of all previously discovered islands and islets north of "Inuit Qeqertaat" (Kaffeklubben Island) at latitude 83°39 054″ N, 30°37 045″ W. Measurements by Martin Nissen from the Danish and Greenlandic national mapping agency and René Forsberg with DTU Space, Technical University of Denmark confirmed that all offshore islets north of Inuit Qeqertaat (Kaffeklubben Island) have been debris-covered icebergs.
