根據"The Annual Report of the Secretary of the Navy, for the Year 1882"一書, "A sled party landed, hoisted the national ensign, and took possession in the name of the United States. The excursion, led by George W. Melville, landed on June 2 or 3, constructed a cairn, and placed inside it a record of their visit.
During the Imperial Russian Arctic Ocean Hydrographic Expedition of 1910–1915 led by Boris Vilkitsky, the Vaygach approached Jeannette Island with the intention of mapping Jeannette and Henrietta Islands, but heavy ice blocked the approach. In 1916 the Russian ambassador in London issued an official notice to the effect that the Imperial government considered Henrietta, along with other Arctic islands, integral parts of the Russian Empire. This territorial claim was later maintained by the Soviet Union.
Some U.S. individuals assert American ownership of Jeannette Island, and others of the De Long group, based on the 1881 discovery. However, the United States government has not pursued De Long's claim to Jeannette Island, and recognizes it as Russian territory.
