Kerguelen Islands

The Kerguelen Islands are a remote archipelago in the sub-Antarctic region.

They sit in the southern Indian Ocean. These islands are part of the French Southern and Antarctic Lands. They are administered as a separate district by France. The islands are among the most isolated places on Earth. The closest territory is the Heard and McDonald Islands of Australia. Madagascar is the nearest inhabited territory, located over 3,000 kilometers away.

Geologically, the islands are part of the Kerguelen Plateau. This is a large igneous province. Most of this plateau is submerged beneath the southern Indian Ocean. The islands represent the exposed parts of this massive structure. The main island is named Grande Terre. It has an area of about 7,215 square kilometers. This makes it roughly three-quarters the size of Corsica. The archipelago includes Grande Terre and 300 smaller islands and islets.

The climate of the islands is harsh and chilly. Frequent high winds blow across the land throughout the year. The surrounding seas are generally rough. However, the waters remain ice-free all year round. The landscape features many bays, inlets, and fjords. There are also many peninsulas and promontories. The highest point is Mont Ross in the Gallieni Massif. It reaches an elevation of 1,850 meters.

Another major feature is the Cook Ice Cap. This is France's largest glacier. It covers about 430 square kilometers on the west-central part of the island.

Glaciers cover just over 1,000 square kilometers of the islands in total.

History shows that the islands were known to some before official discovery. A 1754 map by Philippe Buache showed an "Ile de Nachtegal." This name might refer to Abel Tasman's ship, the De Zeeuwsche Nachtegaal. However, the location on that map was not quite correct. The islands were officially discovered on February 12, 1772. A French navigator named Yves-Joseph de Kerguelen-Trémarec led this expedition. The next day, Charles de Boisguehenneuc landed and claimed the land for France. In 1776, Captain James Cook visited the islands. He found a message left by the French explorers. Cook named the area Kerguelen Land to honor them. He also called them the Desolation Islands because the landscape looked sterile.

Following discovery, the islands entered a period of intense exploitation. Between 1781 and 1922, the archipelago saw 284 recorded sealing visits. Whalers and sealers from Britain, America, and Norway arrived frequently. They hunted resident populations of whales and seals. This hunting drove fur seals and elephant seals toward near extinction. Modern industrial sealing occurred intermittently between 1908 and 1956. Many relics from this era still exist today. You can find try pots, hut ruins, graves, and inscriptions. Since the end of the sealing era, many species have increased their populations again.

Other groups have used the islands for science and industry. In 1874 and 1875, expeditions visited to observe the transit of Venus. This is when the planet Venus passes in front of the sun. Scientists set up stations at Observatory Bay and Thumb Peak. In 1877, the French attempted a coal mining operation, but it was soon abandoned. Later, there were attempts at sheep farming. In 1901, the Australian government tried to acquire the islands for strategic naval use. The British government rejected this proposal in August 1901. They did not believe the islands posed a strategic threat.

Today, the islands have no indigenous inhabitants. They are occupied by scientific research teams and a small military presence. France maintains between 45 and 100 personnel on the islands. These people include scientists, soldiers, and engineers. They live at the scientific base called Port-aux-Français.

This base is located on the eastern shore of the Gulf of Morbihan. It contains research buildings, a hospital, a library, and a satellite tracking station. Because there are no airports, all travel must be by ship.

The islands remain a vital site for studying the sub-Antarctic environment.
