Discovery Investigations in the context of "Helmet Peak, Livingston Island"

Cook Island is the central and largest island of the Southern Thule island group, part of the South Sandwich Islands in the far south Atlantic Ocean. Southern Thule was discovered by a British expedition under Captain James Cook in 1775. Cook Island was named for Cook by a Russian expedition under Fabian Gottlieb von Bellingshausen, which explored the South Sandwich islands in 1819–1820.

The island was surveyed in 1930 by Discovery Investigations (DI) personnel on Discovery II, who charted and named many of its features. Other names were later applied by the United Kingdom Antarctic Place-Names Committee (UK-APC).

Needle Peak is a sharply-pointed black peak, 370 m, standing at the west side of Brunow Bay on the south coast of Livingston Island in the South Shetland Islands. It is situated in the southeast foothills of Friesland Ridge, Tangra Mountains on Rozhen Peninsula, 1 km south-southeast of Ludogorie Peak, and surmounts Prespa Glacier on the west, Brunow Bay on the northeast, Opitsvet Lake on the east and Samuel Point on the east by south.

The feature was named ‘Barnards Peak’ on James Weddell's chart published in 1825, but the name ‘Needle Peak’, given by Discovery Investigations personnel following a 1935 survey, has succeeded it in usage. The name Barnard Point has been approved for the nearby point at the southeast side of False Bay.

Renier Point (62°36′34″S 59°48′21″W / 62.60944°S 59.80583°W / -62.60944; -59.80583) is a narrow point forming the east extremity of both Burgas Peninsula and Livingston Island in the South Shetland Islands, Antarctica. The feature was known to sealers as Point Renier as early as 1821. The name ‘Pin Point’, given by Discovery Investigations personnel on the Discovery II in 1935, has been rejected in favor of the original name.

Moon Bay is a bay 7 nautical miles (13 km) wide which recedes 4 nautical miles (7 km) between Edinburgh Hill and Renier Point, on the east side of Livingston Island, in the South Shetland Islands off Antarctica. The glaciers Sopot Ice Piedmont, Iskar, Huron, Struma, Kaliakra, Panega and Debelt feed the bay. Both Half Moon Island and Elemag Reef lie in Moon Bay.

The bay was known to sealers in the area as early as 1821. It was recharted in 1935 by Discovery Investigations personnel on the Discovery II, and probably named by them for nearby Half Moon Island, which lies in the entrance to the bay.

William Scoresby Bay is a coastal embayment at the western side of William Scoresby Archipelago, Antarctica. It is 8 kilometres (5 mi) long and 5.6 kilometres (3.5 mi) wide, with shores marked by steep rock headlands and snow-free hills rising to 210 m. The practical limits of the bay are extended 6.4 kilometres (4 mi) northward, from the coast by island groups located along its east and west margin. Discovered in February 1936 by Discovery Investigations (DI) personnel on the RRS William Scoresby, for which the bay was named. The bay separates the Kemp Coast to the east from the Mawson Coast to the west. The Hobbs Islands sit 19 kilometres (10 nmi) northeast.

Sperring Point (67°24′S 59°31′E / 67.400°S 59.517°E / -67.400; 59.517) is a rocky point about midway along the west side of the bay. Like the bay, it was discovered and named by DI personnel in February 1936.
