茹安維爾島
Joinville Island is the largest island of the Joinville Island group, about long in an east-west direction and wide, lying off the northeastern tip of the Antarctic Peninsula, from which it is separated by the Antarctic Sound. Joinville Island was discovered and charted roughly during 1838 by a French expedition commanded by Captain Jules Dumont d'Urville, who named it for Prince François, Prince of Joinville (1818–1900), the third son of Louis-Philippe, Duke of Orléans. It is within the Argentine, British and Chilean Antarctic claims.
