History
Before being officially catalogued in 1772, the Kerguelen Islands appear as the "Ile de Nachtegal" on
Philippe Buache
Philippe Buache (born La Neuville-au-Pont, 7 February 1700; died Paris, 24 January 1773) was a French geographer, known for inventing a new system of geography and popularizing this field.

It is possible this early name was after
Abel Tasman
Abel Janszoon Tasman (; 160310 October 1659) was a Dutch seafarer, explorer, and merchant, best known for his voyages of 1642 and 1644 in the service of the Dutch East India Company (VOC). He was the first known European explorer to reach New ...
's ship ''De Zeeuwsche Nachtegaal''. On the Buache map, "Ile de Nachtegal" is located at 43°S, 72°E, about 6° north and 2° east of the accepted location of Grande Terre.
The islands were officially discovered by the French navigator
Yves-Joseph de Kerguelen-Trémarec on 12 February 1772. The next day, Charles de Boisguehenneuc landed and claimed the island for the French crown. Yves de Kerguelen organised a second expedition in 1773 and arrived at the ''"baie de l'Oiseau"'' by December 1773. On 6 January 1774 he commanded his lieutenant, Henri Pascal de Rochegude, to leave a message notifying any passers-by of the two passages and of the French claim to the islands.
Thereafter, a number of expeditions briefly visited the islands, including the
third voyage of
Captain James Cook in December 1776. Cook verified and confirmed the passage of de Kerguelen by discovering and annotating the message left by the French navigator.

Soon after its discovery, the archipelago was regularly visited by whalers and sealers (mostly British, American, and Norwegian) who hunted the resident populations of whales and seals to the point of near extinction, including fur seals in the 18th century and elephant seals in the 19th century. The sealing era lasted from 1781 to 1922 during which time 284 sealing visits are recorded, nine of which ended when the vessel was wrecked.] Modern industrial sealing, associated with whaling stations, occurred intermittently between 1908 and 1956. Since the end of the whaling and sealing era, most of the islands' species have been able to increase their population again. Relics of the sealing period include try pots, hut ruins, graves and inscriptions.[

In 1825, the British sealer John Nunn and three crew members from ''Favourite'' were shipwrecked on Kerguelen until they were rescued in 1827 by Captain Alexander Distant during his hunting campaign.
The islands were not completely surveyed until the Ross expedition of 1840.

. For the 1874 transit, George Biddell Airy of the U.K. Royal Observatory organised and equipped five expeditions to different parts of the world. Three of these were sent to the Kerguelen Islands and led by Stephen Joseph Perry, who set up his main observation station at Observatory Bay and two auxiliary stations, one at Thumb Peak led by Sommerville Goodridge, and the second at Supply Bay, led by Cyril Corbet. Observatory Bay was also used by the German Antarctic Expedition, led by Erich Dagobert von Drygalski

Until 1955, the Kerguelen Islands were administratively part of the French Colony of Madagascar and Dependencies. That same year, they collectively became known as ' (French Southern and Antarctic Lands) and were administratively part of the French '. In 2004 they were permanently transformed into their own entity (keeping the same name) but having inherited another group of five very remote tropical islands, '' '', which are also ruled by France and are dispersed widely throughout the southern Indian Ocean.

Port-aux-Français, a scientific base, is along the eastern shore of the Gulf of Morbihan on La Grande Terre. Facilities there include scientific-research buildings, a satellite tracking station, dormitories, a hospital, a library, a gymnasium, a pub, and the chapel of Notre-Dame des Vents.

* Molloy (Pointe Molloy) is a former observatory west of the present-day Port-Aux-Français, on the northern shore of the Golfe du Morbihan (Kerguelen). An American expedition led by G. P. Ryan erected a station at this site on 7 September 1874. That station was also established to observe the 1874 transit of Venus.
* Port Bizet is a seismographic station on the northeastern coast of Île Longue. This also serves as the principal sheep farm for the island's resident flock of Bizet sheep.
* Port Christmas is a former geomagnetic station on Baie de l'Oiseau, in the extreme northwest of the Loranchet Peninsula. It was named by Captain James Cook, who re-discovered the islands and who anchored there on Christmas Day, 1776. This is also the place where Captain Cook coined the name "Desolation Islands" in reference to what he saw as a sterile landscape.
* Port Couvreux, a former whaling station, experimental sheep farm, and geomagnetic station is on Baie du Hillsborough, on the southeast coast of Presqu'île Bouquet de la Grye. Starting in 1912, sheep were raised here to create an economic base for future settlement. However, the attempt failed and the last inhabitants had to be evacuated, and the station abandoned, in 1931. The huts remain, as well as a graveyard with five anonymous graves. These are those of the settlers who were unable to survive in the harsh environment.
* Port Curieuse, a harbor on the west coast across Île de l'Ouest, was named after the ship ''La Curieuse'', which was used by Raymond Rallier du Baty on his second visit to the islands (1913–14).
* Port Douzième (Twelfth Port) is a hut and former geomagnetic station on the southern shore of the Golfe du Morbihan.
* Port Jeanne d'Arc is a former whaling station founded by a Norwegian whaling company in 1908, and a former geomagnetic station, and lies in the northwestern corner of Presqu'île Jeanne d'Arc, looking across the Buenos Aires passage to Île Longue ( northeast). The derelict settlement consists of four residential buildings with wooden walls and tin roofs, and a barn. One of the buildings was restored in 1977, and another in 2007.
From 1968 to 1981, a site just east of Port-aux-Français was a launching site for sounding rockets, some for French ( Dragon rockets), American ( Arcas) or French-Soviet ( Eridans) surveys, but at the end mainly for a Soviet program ( M-100).

All climate readings come from the Port-aux-Français base, which has one of the more favourable climates in Kerguelen because of its proximity to the coast and its location in a gulf sheltered from the wind.
The average annual temperature is with an annual range of around . The warmest months of the year include January and February, with average temperatures between . The coldest month of the year is August with an average temperature of . Annual high temperatures rarely surpass , while temperatures in winter have never been recorded below at sea level.
Kerguelen receives frequent precipitation, with snow throughout the year as well as rain. Port-aux-Français receives a modest amount of precipitation ( per annum) compared to the west coast which receives an estimated three times as much precipitation per year.
The mountains are frequently covered in snow but can thaw very quickly in rain. Over the course of several decades, many permanent glaciers have shown signs of retreat, with some smaller ones having disappeared completely.
