Dumoulin Islands
Group of islands in Adélie Land, Antarctica

The Dumoulin Islands are a small group of rocky islands in the Antarctic region at the northeast end of the Géologie Archipelago, 4.6 kilometres (2.5 nmi) north of Astrolabe Glacier Tongue. On 22 January 1840, a French Antarctic expedition led by Captain Jules Dumont d'Urville, aboard his flagship Astrolabe, landed a party on one of these islands, Rocher du Débarquement. Dumont d'Urville named the group of islands in honor of the hydrographer of his expedition, Clément Adrien Vincendon-Dumoulin.
The islands were roughly charted by the Australasian Antarctic Expedition, 1911–14, under Douglas Mawson. The island group was photographed from the air by U.S. Navy Operation Highjump, 1946–47, and recharted by a French Antarctic Expedition under André-Frank Liotard, 1949–51.

Why this record matters
The phrase “group of islands in Adélie Land, Antarctica” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 13, 2026. The linked authority identifier is Q5313956. Authority coordinates are -66.617, 140.067. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1840, 1911, 1946 and 1949.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
