Hughes Bay (64°13′S 61°20′W / 64.217°S 61.333°W / -64.217; -61.333 (Hughes Bay)) is a bay lying between Cape Sterneck and Cape Murray along the west coast of the Antarctic Peninsula.[1]

Hughes Bay is on the Danco Coast of the Antarctic Peninsula, on the west side of Graham Land. It is west of the southern end of the Detroit Plateau and north of the Herbert Plateau. It faces Two Hummock Island to the northwest across the Gerlache Strait. Major glaciers flowing into the bay include Sikorsky Glacier, Cayley Glacier and Blériot Glacier. The Argentine Base Primavera is on a headland in the north part of the bay.[2] Hughes Bay is 42 kilometres (26 mi) wide and indents the Danco Coast by 20 kilometres (12 mi). It lies south of Chavdar Peninsula and north of Pefaur (Ventimiglia) Peninsula.


The name "Hughes Bay" has appeared on maps for over 100 years, and commemorates Edward Hughes, master of the Sprightly, a sealing vessel owned by the London whaling company Samuel Enderby & Sons, which explored in this area in 1824–25.[1]


The first recorded landing on the Antarctic mainland was made in the area of this bay by Captain John Davis (see Davis Coast) from the shallop Cecilia (see Cecilia Island), tender to his ship Huron (see Huron Glacier) on 7 February 1821. The bay was roughly charted by James Hoseason, First Mate in the British sealer Sprightly (see Sprightly Island) in December 1824 and was named Hughes' Bay after Captain Edward Hughes, the ship's master The bay was further charted by the Belgian Antarctic Expedition (BeAE) during 23-25 January 1898. Air photography of the area by the Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) in 1956-57 led to important changes in topography and outline of the bay, as shown on maps and charts. Prior to this time many identifications of names in the area were no more than guesses.[3]


Glaciers feeding the bay, from northeast to southwest, include: Tumba Ice Cap, Gregory Glacier , Breguet Glacier, Sikorsky Glacier, Trepetlika Glacier, Mouillard Glacier, Lilienthal Glacier, Cayley Glacier, Blériot Glacier, Zimzelen Glacier, Krapets Glacier, Agalina Glacier.

Afuera Islands[edit]

Afuera Islands 64°20'S, 61°36'W Group of three small islands lying N of Challenger Island and just outside the S entrance point to Hughes Bay. First charted by the FrAE, 1908-10, under Charcot. The name, which appears on an Argentine government chart of 1957, is probably descriptive of the islands' location; "Afuera" means outer or outside.[4]
