Through Archipelago, China and Reef

The word paracel is of Portuguese origin, meaning placer (a submerged bank or reef), and appears on 16th-century Portuguese maps. The archipelago includes about 130 small coral islands and reefs, most grouped into the northeastern Amphitrite Group or the western Crescent Group. They are distributed over a maritime area of around 15,000 square kilometers (5,800 sq mi), with a land area of approximately 7.75 square kilometers (2.99 sq mi). The archipelago is located about 220 miles (350 km) southeast of Hainan Island, equidistant from the coastlines of the People's Republic of China (PRC) and Vietnam, and approximately one-third of the way between central Vietnam and the northern Philippines. A feature of the Paracel Islands is Dragon Hole, the second deepest blue hole (underwater sinkhole) in the world. Sea turtles and seabirds are native to the islands, which have a hot and humid climate, abundant rainfall and may experience annual typhoons. The archipelago is surrounded by productive fishing grounds and a seabed potentially containing unexplored oil and gas reserves.

Climate

The climate is different from nearby continental land masses with the lower air mass temperatures being 1 to 2 °C (1.8 to 3.6 °F) cooler than land at the same latitude, and with higher relative humidity due to the maritime air mass. The air mass over the Paracel Islands has about a 5 °C (9.0 °F) variation in annual temperature compared to the 2.2 °C (4.0 °F) observed over the Spratly Islands.

Amphitrite group

The Amphitrite group was named after the French frigate Amphitrite, which observed the islands while carrying a Jesuit mission to Canton in 1698–1700.

Lying in the northeast of the Paracel Islands at 16°53′N 112°17′E / 16.883°N 112.283°E, the group consists of low, narrow islands with sand cays and enclosed shallow lagoons connected by reefs of rock. It is about 37 km (23 mi) northwest of Lincoln Island. The group approximately forms an ellipse with a north–south axis of 22 km (14 mi).

The northern section of the group comprises West Sand, Tree Island, and the Qilian Yu (七连屿, "seven sisters") sub-group: North Island, Middle Island, South Island, North Sand, Middle Sand, South Sand, and two small sands (New West Sand and New East Sand). The center of the group consists of Woody Island and Rocky Island, approximately 5 km (3 mi) south of the southern tip of the eastern extremity of the northern section. The southwest corner of the group is occupied by the Iltis Bank.

The largest island of the Paracels, Woody Island (which has an area of 213 ha (530 acres)), has over 1,000 residents including fishermen and their families, military personnel, and civilian administrators.

Crescent group

Lying about 70 km (43 mi) southwest of the Amphitrite group, at 16°30′N 111°42′E / 16.5°N 111.7°E, the Crescent group consists of islands and reefs that form a crescent-like structure from west to east, enclosing a deep central lagoon. The group measures 31 by 15 km (19 by 9 mi) east-west and north–south. All of the islands in the group support vegetation except on their small cays.

The islands are named after former senior figures in the British East India Company (EIC). Three were members of the EIC's 'Select Committee' in Canton: James Drummond, Thomas Pattle and John William Roberts. Jonathan Duncan was Governor in Council of Bombay, and William Taylor Money was Superintendent of the Bombay Marine.

Money Island lies at the southwest extremity of the group, and has some small cays on the southern side. While the island's English name was named after William Taylor Money, the Chinese name is Jin Yin Dao, a literal translation of "money island".
Antelope Reef, submerged at high tide and containing a central lagoon, lies 2.4 km (1.5 mi) east of Money Island.
Northeast of this are Robert Island (also named Round Island) and Pattle Island, separated from each other by a 3.5 km (2.2 mi) wide deep channel. A weather station was built on Pattle Island (by the French) in 1932, and a lighthouse and radio station in 1937.
Northeast of this is Quanfu Dao ("All Wealth Island").
Observation Bank, also named Silver Islet, and the Lesser Silver Islet, are the northernmost of the group and contain a small cay.
Just south of them are Yagong Dao (He Duck) and Xianshe Yu (Salty Hut).

At the eastern side of the group lies a 12 km (7 mi) long boomerang shaped reef with Stone Islet at its north end and Drummond Island at its south end. Near the centre of the reef is Dragon Hole the second deepest known sinkhole in the world.

The Duncan Islands (16°27′N 111°43′E / 16.450°N 111.717°E), consisting of Duncan Island and Palm Island, lie approximately 3 km (2 mi) west of Drummond Island and about 8 km (5 mi) east of Antelope Reef. Kuangzai Shazhou (Little Basket) lies about halfway between Palm Island and Antelope Reef.

Other features

Taking 16°40′N 112°20′E / 16.667°N 112.333°E as the center of the Paracel Islands, then the Amphitrite Group is ENE, and the Crescent Group is West.

Southeast

  • Bombay Reef: This elongated reef is situated at the southeastern corner of the Paracel Islands (16°00′N 112°30′E / 16°N 112.5°E) and lies approximately 90 km (56 mi) southeast of the Crescent group. With most parts submerged, the reef measures approximately 18 by 5 km (11 by 3 mi) (E-W by N-S). Bombay Reef encloses a deep lagoon with rocks on its edge.

Eastern sub-group

  • Bremen Bank: Located 24 km (15 mi) north of Bombay Reef (16°18′N 112°30′E / 16.3°N 112.5°E), is the southwesternmost feature of this subgroup. This submerged shallow bank measures approximately 23 km (14 mi) in length from northeast to southwest. The shallowest area reaches a depth of about 12 meters (39 ft) and is located in the southwestern part of the bank.
  • Jehangire Bank: East of the Bremen Bank at 16°18′N 112°42′E / 16.3°N 112.7°E
  • Neptuna Bank: North of the Bremen Bank at 16°30′N 112°30′E / 16.5°N 112.5°E
  • Pyramid Rock: NE of the Neptuna Bank at 16°36′N 112°36′E / 16.6°N 112.6°E
  • Lincoln Island: Surrounded by a coral reef, located 37 km (23 mi) southeast from the Amphitrite Group at 16°42′N 112°42′E / 16.7°N 112.7°E, the island is covered with brushes and fairly high trees, including coconut palm trees. The depth increases sharply on the northern and eastern sides of the island but the southern and south western regions are shallow. An observation post on the western side was found by officers of the German government surveys in 1883. In 1948, Great Britain requested France for permission to use the feature for military exercises.

Northeast

  • Dido Bank: Separate from, and NE of, the Eastern sub-group at 16°49′N 112°53′E / 16.817°N 112.883°E

(ENE: Amphitrite group)

16°53′N 112°17′E / 16.883°N 112.283°E

Northwest

  • North Reef: Situated approximately 56 km (35 mi) north from the Crescent group and about 70 km (43 mi) west-northwest from the Amphitrite group at 17°06′N 111°30′E / 17.1°N 111.5°E, the reef is the most northwesterly feature of the Paracel Islands. Most parts of the reef are submerged. There are rugged rocks are around the edge that are barely above water. There is a passage into the lagoon on the southwestern side of the reef.

(West: Crescent group)

Inner southwest

  • Discovery Reef: Measuring approximately 27 km (17 mi) in length from east to west, and 7 km (4 mi) from north to south, the reef is located about 18 km (11 mi) south of the Crescent Group at 16°15′N 111°42′E / 16.25°N 111.7°E. Completely submerged, the elongated ring structure is the largest single reef in the Paracel Islands. The reef has two large, deep openings into the lagoon on its southern side.
  • Passu Keah: This small reef encloses a shallow lagoon and is located about 12 km (7 mi) south of the eastern side of Discovery Reef at 16°06′N 111°48′E / 16.1°N 111.8°E, approximately 37 miles (60 km) east-northeast from Triton Island. The sand cay measures 9 km (6 mi) in length.

Outer southwest

  • Triton Island: The sand cay supports vegetation and stands on a steep-sided coral reef measuring 1.5 km (1 mi) in length. This southwesternmost island of the Paracels is situated about 56 km (35 mi) from Discovery Reef at 15°48′N 111°12′E / 15.8°N 111.2°E.

Central

  • Vuladdore Reef: Located slightly south of the center of the group at 16°18′N 112°00′E / 16.3°N 112°E, this mostly submerged reef is orientated east–west and measures approximately 12 km (7 mi) by 3 km (2 mi). Some small spiral rocks are to be seen on the reef.
