Description (see definition): Island 2.5 mi long, lying 0.5 mi N of Andersson Island in the S entrance to Antarctic Sound, off the NE tip of Antarctic Peninsula. This island was named Irizar Island by the Swedish Antarctic Expedition (SwedAE), 1901-04, under Nordenskjold, for Captain Julian Irizar of the Argentine ship Uruguay, who rescued the shipwrecked Swedish Antarctic Expedition (SwedAE) in 1903. In 1904 Dr. Jean B. Charcot, apparently unaware of the Swedish naming, gave the name Irizar to an island off the W coast of Antarctic Peninsula. Since it is confusing to have two islands in close proximity identically named, and because Charcot's Irizar Island has appeared more widely on maps and in reports, the Advisory Committee on Antarctic Names (US-ACAN) accepts the decision of the UK Antarctic Place-names Committee (UK-APC) that the name given this island by Nordenskjold be altered. The new name commemorates Ole Jonassen, who accompanied Nordenskjold on his two principal sledge journeys in 1902-03.
