Îlots Des Apôtres
The Îlots des Apôtres or Îles des Apôtres () are a group of small and uninhabited rocky islands in the north-western part of the Crozet Islands, Crozet Archipelago in the southern Indian Ocean, north of Île aux Cochons. Their total area is about . Description There are two larger islands (Île Grande - Big Island, and Île Petite - Little Island), together occupying almost 90 percent of the area. The highest peak is Mont Pierre ( on Île Grande. In addition, there are about 20 rocks, with elevations between . The islands are very steep. Despite their small size, Île Grande reaches a height of , and Île Petite . History On the night of 1 July 1875, the ''Strathmore'', a three-masted ship sailing between the United Kingdom and New Zealand, was wrecked in the vicinity after striking a reef. Of the 89 passengers on board, 44 survived on Île Grande until 21 January 1876, when they were rescued by another ship. Important Bird Area The islets have been identified as an Impor ...

Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-chinned Petrel
The white-chinned petrel (''Procellaria aequinoctialis'') also known as the Cape hen and shoemaker, is a large shearwater in the family Procellariidae. It ranges around the Southern Ocean as far north as southern Australia, Peru and Namibia, and breeds colonially on scattered islands. The white-chinned petrel was formerly considered to be conspecific with the spectacled petrel (''Procellaria conspicillata''). Taxonomy In 1747 the English naturalist George Edwards included an illustration and a description of the white-chinned petrel in the second volume of his ''A Natural History of Uncommon Birds''. He used the English name "The great Black Peteril" and based his hand-coloured etching on a preserved specimen that had been brought to London. He believed that it had been collected near the Cape of Good Hope. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the white-chinned petrel with the other petrels in the ...

Important Bird Areas Of The Crozet Islands
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So in this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world is and how the world would have been withou ...

French Overseas Departments And Territories
Overseas France (, also ) consists of 13 French territories outside Europe, mostly the remnants of the French colonial empire that remained a part of the French state under various statuses after decolonisation. Most are part of the European Union. "Overseas France" is a collective name; while used in everyday life in France, it is not an administrative designation in its own right. Instead, the five overseas regions have exactly the same administrative status as the thirteen metropolitan regions; the five overseas collectivities are semi-autonomous; and New Caledonia is an autonomous territory. Overseas France includes island territories in the Atlantic, Pacific and Indian oceans, French Guiana on the South American continent, and several peri-Antarctic islands as well as a claim in Antarctica. Excluding the district of Adélie Land, where French sovereignty is effective ''de jure'' by French law, but where the French exclusive claim on this part of Antarctica is fro ...

Administrative Divisions Of France
The administrative divisions of France are concerned with the institutional and territorial organization of French territory. These territories are located in many parts of the world. There are many administrative divisions, which may have political (local government), electoral (districts), or administrative (decentralized services of the state) objectives. All the inhabited territories are represented in the National Assembly, Senate and Economic and Social Council and their citizens have French citizenship and elect the President of France. Types of division Regions, the most integrated territories The French Republic is divided into 18 regions: 12 in mainland France and 6 elsewhere (1 in Europe: Corsica; 2 in the Caribbean (the Lesser Antilles): Guadeloupe and Martinique; 1 in South America: French Guiana; and 2 in the Indian Ocean near East Africa: Mayotte and Réunion). They are traditionally divided between the metropolitan regions, located on the European ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare (" hecto-" + "are") was thus 100 ''ares'' or km2 ( square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa () and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is ...

Kerguelen Tern
The Kerguelen tern (''Sterna virgata'') is a tern of the southern hemisphere. This seabird mainly breeds colonially in the Kerguelen Islands, as its common name implies. However, smaller colonies are also found in the Prince Edward Islands (i.e. Prince Edward and Marion) and Crozet Islands. The total number of individuals is from 3,500 to 6,500 birds, although there is no recent data from the main colony at Kerguelen. These birds do not inhabit Kerguelen proper, instead nesting on islets free of feral cats. During bad weather, they are known to abandon their colonies. Kerguelen terns are among the least-ranging of all typical terns. They generally do not reach far into the seas near their breeding grounds. These birds eat fish and marine invertebrates, especially those found in beds of the seaweed Macrocystis spp. They sometimes also hunt insects on land and catch fish from rivers on Kerguelen. There are two subspecies In Taxonomy (biology), biological classificatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-eyed Shag
''Leucocarbo'' is a genus of birds in the family Phalacrocoracidae. Several species within the genus are collectively known as blue-eyed shags. This is a group of closely related cormorant taxa. Many have a blue, purple or red ring around the eye (not a blue iris); other shared features are white underparts (at least in some individuals) and pink feet. They are found around the colder parts of the Southern Hemisphere, especially near southern South America, Antarctica, and New Zealand. Many are Endemism, endemic to remote islands. Determining which types are species and which are subspecies of what larger species is problematic; various recent authorities have recognized from 8 to 14 species and have placed them in a variety of genera. The common names are even more confusing, "like myriad footprints criss-crossing in the snow and about as easy to disentangle." Only one common name is given for most species here. Taxonomy The genus ''Leucocarbo'' was introduced in 1856 by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Diving Petrel
The common diving petrel (''Pelecanoides urinatrix''), also known as the smaller diving petrel or simply the diving petrel, is a diving petrel, one of four very similar auk-like small petrels of the southern oceans. It is native to South Atlantic islands and islands of the subantarctic southern Indian Ocean, islands and islets off New Zealand and south-eastern Australian islands. Taxonomy The common diving petrel was species description, formally described in 1788 by the German naturalist Johann Friedrich Gmelin. He placed it with the other petrels in the genus ''Procellaria'' and coined the binomial name ''Procellaria urinatrix''. Gmelin based his description on the "diving petrel" that had been described in 1785 by the English ornithologist John Latham (ornithologist), John Latham in the second volume of his ''A General Synopsis of Birds''. Latham reported that they were found in great numbers in Queen Charlotte Sound / Tōtaranui, Queen Charlotte Sound at the northern end of ...

Northern Giant Petrel
The northern giant petrel (''Macronectes halli''), also known as Hall's giant petrel, is a large, predatory seabird of the southern oceans. Its range overlaps broadly with the range of the related southern giant petrel (''Macronectes giganteus''), albeit slightly further to the north. Taxonomy The northern giant petrel was species description, formally described in 1912 by the Australian born ornithologist Gregory Mathews as a subspecies of the southern giant petrel with the trinomial name ''Macronectes giganteus halli''. The specific epithet ''halli'' was chosen to honour the Australian ornithologist Robert Hall (ornithologist), Robert Hall who had described the birds breeding on the Kerguelen Islands. The northern giant petrel is now considered to be a separate species and has the binomial name ''Macronectes halli''. It is monotypic: no subspecies are recognised. The genus name combines the Ancient Greek ''makros'' meaning "great" and ''nēktēs'' meaning "swimmer". The name "pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
