COMPOSITE GAZETTEER OF ANTARCTICA

NE of Snow Hill Island, separated from James Ross Island by Admiralty Sound, was sighted by Ross, 6 January 1843, described as the NE headland of the sound and, as such, named Cape Seymour after Rear Adm. (later Adm. of the Fleet) Sir George Francis Seymour, RN (1787-1870), a Lord of the Admiralty, 1841-44 (BA chart 1238, 1844; Ross, 1847a, p.343; BA, 1916, p.401). Cabo Seymour (Spain. DH chart 458, 1861). The feature was roughly charted by Larsen, 1892-93 and 1893-94, when its insularity was determined; landings were made, 2 December 1892 and 18 November 1893, when the first fossils recorded from the Antarctic were collected, and the island was claimed for Norway (Schück, 1894, p.139).

Island 10 mi long and 5 mi wide at its greatest breadth, lying 1 mi NE of Snow Hill Island at the S margin of Erebus and Terror Gulf The NE end of this feature was sighted by a British expedition under Ross, Jan. 6, 1843, and named Cape Seymour after R. Admiral George Francis Seymour. Its insular nature was determined by Capt. C.A. Larsen in 1892-93 and the name Seymour has since been extended to the entire island.

El 6 de junio de 1843, la Expedición Británica de James Ross avistó la costa NE de esta isla, dándole el nombre de cabo Seymour. Su naturaleza insular fue determinada por Larsen en 1892-1893. Ubicada a 11 millas al SW de cabo Gage de la isla Ross. Mide 10 millas de largo por 3 de ancho medio. La isla se caracteriza por estar libre de hielos en verano, se compone de dos masas montañosas separadas por una profunda quebrada transversal que la cruza de costa a costa a nivel del mar. Su parte NE es de relieve regular, en cambio la parte SW es más baja y quebrada.
