Penguins, seals, and scientists are among the residents of a remote archipelago in the southern Indian Ocean. In a small overseas territory of France, scientists are finding further evidence of global climate change. Land. Such is the case of the Kerguelen Islands, where the climate is chronically cool and windy year-round, as is typical for the sub-Antarctic islands generally (Convey 1996 ), with a mean annual temperature of 4.84 C for the period 1976-2008 (Lebouvier et al. Image of the Day (Weather station: Port-Aux-Francais Iles Kerguelen, French Southern Territories). Very little wildlife inhabits the island, with penguin and seal populations making up most of the living organisms you can find on this incredibly cold and windy landmass. Grande Terre (French for large land) is the most sizeable in the island group. Recent glacier decline in the Kerguelen Islands (49S, 69E) derived from modeling, field observations, and satellite data. Then in December of 1776, British explorer Captain James Cook, on his third voyage, anchored his ship on the island, which comprised of some 300 smaller islands and islets covering roughly 7,215 square kilometres.

Although the Kerguelen Islands are part of the French territory now, they are comparatively closer to the Antarctic region than to Europe. Recovery of native plant communities after eradication of rabbits from the subantarctic Kerguelen Islands, and influence of climate change. Cook Glacier covers nearly one third of the island, and the abundant rainfall combined with glacial meltwater keeps numerous streams and lakes full of water.

Another English voyager John Nunn, became shipwrecked on the islands in the year 1825 and lived there with his crew for two long years, surviving on bird eggs and seal meat, until help arrived eventually. We used a unique dataset of foraging, breeding success, and climate data spanning over 25 years to examine the links between climate, marine environment, and breeding success at this colony.

Kerguelen - Wikitravel Our study on the Kerguelen Islands confirms this trend and demonstrates that the effects of warming (+ 1.3C since the mid 1960s) and summer droughts on plants and invertebrates are now visible. Adelie Land: The only non-insular district of the TAAF is the Antarctic claim known as "Adelie Land."

Water Kerguelen - Travel guide at Wikivoyage Unlike the terrestrial vegetation which is very poorly developed, the marine flora is flourishing, in particular thanks to the presence of giant brown algae: the kelp (Macrocystis pyrifera), which form true underwater forests, and the cochayuyo (Durvillaea antarctica), which covers most of the rock coasts. The largest island is Grand Terre (120 by 150 km), with the capital city of . Land. The establishment of other mammals also had consequences on the vegetation: consumption of the seeds of the Kerguelen cabbage by mice, reducing its regeneration capacities, consumption of the lichens by reindeer, etc. The present study provides an overview of the vulnerability of sub-Antarctic terrestrial communities with respect to two interacting factors, namely climate change and alien insects.

A rare break in the clouds on February 15, 2007, gave the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Terra satellite a chance to capture this photo-like image of the Kerguelen Islands. As Kerguelen is located in the subantarctic zone, the islands have a cold oceanic climate, harsh owing to the presence of cold waters coming from the Antarctic, with rain or snow most of the year. That day, the mean daily temperature was 4.5 degrees Celsius (40.1 degrees Fahrenheit), with mean westerly winds of 9 meters per second (about 20 miles per hour).
