Northernmost point of land

{{Short description|none}}

The northernmost point of land on Earth 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 sheets, water movements and inundation, storm activity that may build, shift, or destroy banks of moraine material, and observational difficulties due to remoteness. However, a bathymetric survey in 2022 confirmed that certain previous contenders, such as 83-42,[http://www.cntraveler.com/daily-traveler/2012/02/ultima-thule-83-42-arctic-greenland-ken-jennings The World's Northernmost Point Is Called 83-42.

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{{cite web|url=http://www.gebco.net/about_us/meetings_and_minutes/documents/gebco_scufn_15_report.pdf |title=IHO-IOC GEBCO Gazetteer |access-date=2008-05-24 |publisher=International Hydrographic Organization/Intergovernmental Oceanographic Commission |date=September 2007 |url-status=dead |archive-url=https://web.archive.org/web/20080911062905/http://www.gebco.net/about_us/meetings_and_minutes/documents/gebco_scufn_15_report.pdf |archive-date=2008-09-11 }} 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.
