COMPOSITE GAZETTEER OF ANTARCTICA

between Alexander Island to E and S, Charcot Island and Latady Island to W, and Rothschild Island to N. The N entrance was roughly charted by FAE, 1908-10, in January 1910 (Charcot, 1912, P1. 1) and described as "a vast estuary encumbered by ice" (Bongrain, 1914, vue 44 following p.60); seen from the air by Wilkins, 29 December 1929, during the flight in which he established the insularity of Charcot Island (q.v.), and sketched from the air in c.70°30'S 72°00'W by USAS, November-December 1940; named Wilkins Strait after Sir Hubert Wilkins (Wilkins Coast, (q.v.) (USAAF chart [LR-74], 1942; Ronne, 1945, map p.14). Estrecho Wilkins (Argentina. IGM map, 1946; Chile. IHA, 1974, p.302). Wilkins Str. (Hansen, chart [no number], 1947). The sound was photographed from the air by RARE in 1947. Estrecho General Zenteno, after Gen. J.I. Zenteno (Cape Church, q.v.) (Orrego Vicuña, 1948, p.198). Estrecho de Wilkins (Argentina. MM, 1953, p.23; Chile. IHA, 1974, p.101). Proliv Uilkinsa (Baranov and others, 1954, map p.283). Stretto di Wilkins, Stretto Wilkins (Zavatti, 1958, Tav. 9, 12-13). The sound was mapped from air photographs by FIDS in 1959.

Wilkens [sic] Sound (USDMAAC chart JNC-117N, 1975).

A sound that is largely occupied by the Wilkins Ice Shelf;, located between the concave western coastline of Alexander Island and the shores of Charcot Island and Latady Island farther to the west. Its northern portion was first seen and roughly mapped in 1910 by the FrAE under J.B. Charcot and was observed from the air in 1929 by Sir Hubert Wilkins. The configuration of the sound was determined in 1940 on exploratory flights by USAS. Named by the USAS for Sir Hubert Wilkins, who in 1929 first proved "Charcot Land" to be an island and thereby indirectly discovered this feature. The existence of Latady Island at the SW side of the sound was determined in 1960 by D.J.H. Searle of FIDS by examination of air photos taken by the RARE, 1947-48.

El estrecho fue determinado por vuelos exploradores, por los miembros de la Base Este de Estados Unidos, en noviembre y diciembre de 1940 y se denominó por la expedición al mando de Sir Hubert Wilkins quien en 1929 probó por primera vez que la tierra de Charcot era una isla y quien por consiguiente descubrió este estrecho en forma indirecta. Estrecho que separa la isla Charcot de isla Alejandro I, y se encuentra en su totalidad cubierto por un campo de hielo. Su entrada N se cierra por la barrera de hielos, la cual avanza y retrocede según las condiciones glaciológicas.
