Trinidad and Tobago is an archipelagic republic in the southern Caribbean between the Caribbean Sea and the North Atlantic Ocean, northeast of Venezuela. They are southeasterly islands of the Lesser Antilles, Monos, Huevos, Gaspar Grande, Little Tobago, and St. Giles Island. Trinidad is 11 km (6.8 mi) off the northeast coast of Venezuela and 130 km (81 mi) south of the Grenadines. The island measures 4,768 km2 (1,841 sq mi) in area with an average length of 80 km (50 mi) and an average width of 59 km (37 mi). The island appears rectangular in shape with three projecting peninsular corners. Tobago is 30 km (19 mi) northeast of Trinidad and measures about 298 km2 (115 sq mi) in area, or 5.8% of the country's area, 41 km (25.5 mi) in length and 12 km (7.5 mi) at its greatest width. The island is cigar-shaped in appearance, with a northeast-southwest alignment.
Tower Island is an Antarctic island 9 kilometres (5 nmi) long and 305 m (1,001 ft) high. It marks the north-east extent of Palmer Archipelago. It lies 37 kilometres (20 nmi) north-east of Trinity Island, separated by Gilbert Strait. Both islands are separated from the Davis Coast to the south by Orléans Strait, running northeast-southwest. The Pearl Rocks lie off the West Coast of Tower Island.
The Windmill Islands are an Antarctic group of rocky islands and rocks about 11.1 kilometres (6 nmi) wide, paralleling the coast of Wilkes Land for 31.5 kilometres (17 nmi) immediately north of Vanderford Glacier along the east side of Vincennes Bay. Kirkby Shoal is a small shoal area with depths of less than 18 metres (59 ft) extending about 140 metres (459 ft) westwards and SSW, about 3.4 kilometres (2.1 mi) from the summit of Shirley Island, Windmill Islands, and 0.24 kilometres (0.15 mi) NW of Stonehocker Point, Clark Peninsula.
The Liancourt Rocks are a group of small islets in the Sea of Japan. While South Korea controls the islets, its sovereignty over them is contested by Japan.
The Ibar Rocks are two rocks located 0.4 kilometres (0.2 nmi) east of Bonert Rock and 1 kilometre (0.6 nmi) southeast of Canto Point, Greenwich Island, in the South Shetland Islands. The names "Islote Ibar" and "Islote Teniente Ibar" appearing on Chilean hydrographic charts in the 1950s refer to the larger and western rock. The recommended name "Ibar Rocks" includes a submerged outlier to the northeast of the larger rock. Teniente (lieutenant) Mario Ibar P. signed the official act of inauguration of the Chilean Captain Arturo Prat Base on Greenwich Island in 1947.
Austskjera is a group of rocks (skerries) in Antarctica, lying close to the coast about 9 kilometres (5 nmi) east of Cape Daly, 4 kilometres (2 nmi) east-southeast of Safety Island, and 3 kilometres (1.5 nmi) east-southeast of Landmark Point. They were mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition, 1936–37, and named "Austskjera".
Andersen Island is an island 7 kilometres (4 nmi) west of Thorgaut Island, and 4 kilometres (2 nmi) east of Child Rocks, in the Robinson Group, Antarctica. It was mapped by the British Australian New Zealand Antarctic Research Expedition under Douglas Mawson in February 1931. The island was also charted from the whaler Thorgaut about the same time. It was named after Captain Lars Andersen of the whaler Falk who had assisted the Discovery with coal.
The Flatvaer Islands, also known as the Ongul Islands, are a group of small islands lying at the east side of the entrance of Lützow-Holm Bay, 4 km from the coastline of Antarctica. They were mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition (LCE), 1936–37. Many of the islands and their features were subsequently named by members of the Japanese Antarctic Research Expedition (JARE); unless otherwise noted, features noted in this article were named by JARE.
The Canopus Rocks are two small, low rocks lying 2 kilometres (1 nmi) northwest of Canopus Island, 2 kilometres (1 nmi) east of Nella Rock and the Sawert Rocks, and 1.9 kilometres (1 nmi) southeast of Hansen Rocks in the eastern part of Holme Bay, Mac. Robertson Land. They were plotted from photos taken from Australian National Antarctic Research Expeditions aircraft in 1958, and named by the Antarctic Names Committee of Australia after Canopus Island.
Casy Island is the largest feature in a group of small islands lying 4 kilometres (2 nmi) southeast of Lafarge Rocks and 6 kilometres (3 nmi) northeast of Coupvent Point, off the north side of Trinity Peninsula. It was discovered and named by a French expedition under Captain Jules Dumont d'Urville, 1837–40.
The Knight Rocks are a group of small rocks which lie 8 kilometres (4.5 nmi) west-northwest of the south end of Snow Island, in the South Shetland Islands. The rocks were so named by the UK Antarctic Place-Names Committee following a survey by Lieutenant Commander F.W. Hunt, Royal Navy, in 1951–52, because of their proximity to Castle Rock.
Pig Rock is a rock, 65 m high, the largest of a group of rocks lying 1.9 kilometres (1 nmi) east of the east end of Nelson Island, in the South Shetland Islands. This rock, known to sealers in the area as early as 1821, was charted and named by DI personnel on the Discovery II in 1935.
Paterson Islands is a group of small islands lying 7.4 kilometres (4 nmi) northeast of Klung Islands, 3.7 kilometres (2 nmi) southeast of Wiltshire Rocks and Kitney Island, and 5.6 kilometres (3 nmi) southeast of Smith Rocks, close along the coast of Mac. Robertson Land. Mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936-37. Named by Antarctic Names Committee of Australia (ANCA) for A.J.F. Paterson, supervisory technician (radio) at Mawson Station, 1963.
The Garnet Rocks are a group of three rocks lying 4 kilometres (2 nmi) east of the Refuge Islands in the northern part of Rymill Bay, off the west coast of Graham Land, Antarctica. They were first surveyed in 1948–49 by the Falkland Islands Dependencies Survey and so named by them because of the occurrence of garnet in the rocks.
The Marshall Archipelago is an extensive group of large ice-covered islands within the Sulzberger Ice Shelf off Antarctica. Several of the islands were discovered and plotted by the Byrd Antarctic Expeditions and by the United States Antarctic Service (1939–41), all led by Admiral Richard E. Byrd. The full extent of the archipelago was mapped by the United States Geological Survey from surveys and U.S. Navy air photos (1959–65). The name was proposed by Admiral Byrd for General of the Army George C. Marshall, who made financial contributions as a private individual and also, on the same basis, provided advisory assistance to the Byrd expedition of 1933–35.
Sawert Rocks is a group of rocks 4.6 kilometres (2.5 nmi) east-northeast of Azimuth Island, and about 3.7 kilometres (2 nmi) southwest of the Hansen Rocks, in the northeast part of Holme Bay, Mac. Robertson Land. Plotted from photos taken from ANARE aircraft in 1958. Named by Antarctic Names Committee of Australia (ANCA) for A. Sawert, radio officer at Mawson Station in 1959. Just to the east of the Sawert Rocks lies Nella Rock.
Topgallant Islands is an island group in the Australian state of South Australia located in the Investigator Group about 22 kilometres south west of Cape Finniss on the west coast of Eyre Peninsula. The group was discovered and named by Matthew Flinders on 13 February 1802. The island group has enjoyed protected area status since the 1960s and since 2011, it has been part of the Investigator Group Wilderness Protection Area.
Dangerous Reef is an island and reef system located in Spencer Gulf in the Australian state of South Australia about 32.5 kilometres (20.2 mi) east-south east of the city of Port Lincoln. It is the southernmost member of the Sir Joseph Banks Group. It has been the site of a navigation aid since 1911. It is notable as the site of a breeding colony of Australian sea lions. The waters adjoining its shore are notable as a place to view great white sharks to the extent that it was both a popular gamefishing and shark cage diving venue during the twentieth century, and was used to film footage for the following motion pictures – Blue Water White Death and Jaws. The island has enjoyed protected area status since 1900 and it has been part of the Sir Joseph Banks Group Conservation Park since 1989.
