George Powell (1794–1824) was an English sealer, explorer and amateur naturalist. He captained three sealing expeditions to the Antarctic Ocean between 1818 and 1822.
Powell was born in London. During his first expedition, in 1818 and 1819, he captained the sloop Dove and visited South Georgia and Kerguelen Islands. His second expedition, captaining Eliza, lasted from 1819 until 1821, during which time he visited the Falkland Islands and the South Shetland Islands.

Tangra Mountains (in Bulgarian Тангра планина, 'Tangra planina' \'tan-gra pla-ni-'na\) (62°40′00″S 60°06′00″W / 62.66667°S 60.10000°W) form the principal mountain range of Livingston Island in the South Shetland Islands, Antarctica. The range had been nameless until 2001, when it was named after Tengri (Bulgarian Tangra), "the name of the ancient Bulgarian god."
Tangra Mountains are 32 kilometres (20 mi) long between Barnard Point and Renier Point, 8.5 kilometres (5.3 mi) wide, and are bounded by Moon Bay and Huron Glacier to the north, Huntress Glacier to the northwest, False Bay to the west, and Bransfield Strait to the southeast, and is linked to Bowles Ridge by Wörner Gap, and to Pliska Ridge by Nesebar Gap. The mountain is divided in three principal ridges: Friesland Ridge in the west, Levski Ridge in the centre, and Delchev Ridge in the east.
False Bay (62°43′S 60°22′W / 62.717°S 60.367°W) is a bay 4 miles (6.4 km) long, which lies between Barnard Point and Miers Bluff on the south side of Livingston Island, in the South Shetland Islands, Antarctica. The glaciers Hurd Ice Cap, Huntress, Ruen Icefall, Peshtera and Charity feed the bay.
It was probably first entered and charted by Captain Nathaniel Palmer in November 1820, and was likely named because of the possibility in thick weather of confusion between this feature and nearby South Bay, where Johnsons Dock was frequented by the early sealers.
Yankee Harbour is a small inner harbour entered from Shopski Cove between Glacier Bluff and Spit Point, indenting the south-west side of Greenwich Island in the South Shetland Islands, Antarctica. It is 2.35 km (1.46 mi) long in west-south-west to east-north-east direction, and 1.6 km (0.99 mi) wide, and is bounded by Provadiya Hook to the south-west, Parvomay Neck to the north and east, and Kladara Beach to the south.
A phantom island is a purported island which has appeared on maps but later found not to exist. They usually originate from the reports of early sailors exploring new regions, and are commonly the result of navigational errors, mistaken observations, unverified misinformation, or deliberate fabrication. Some have remained on maps for centuries before being "un-discovered".
Unlike lost lands, which are claimed (or known) to have once existed but to have been swallowed by the sea or otherwise destroyed, a phantom island is one that is claimed to exist contemporaneously, but later found not to have existed in the first place (or found not to be an island, as with the Island of California).
