Moucha Island
Moucha Island is a small coral island off the coast of Djibouti. It is located at the center of the Gulf of Tadjoura. The island is part of the Djibouti Region; the island has a total population of about 20 inhabitants, which increases considerably during the summer. The island was occupied by Great Britain from 1840 to 1887. History In August 1840, the conclusion of a treaty of friendship and commerce between the Sultan Mohammed bin Mohammed of Tadjoura and Commander Robert Moresby of the Indian Navy describes the sale of Moucha Island to Great Britain for ten sacks of rice. The sale is, however, contingent upon occupation. In 1887, Britain ceded sovereignty of the island to France while recognizing the French sphere of influence in the Gulf of Tadjoura, in exchange for the abandonment by France of any right in Zeila and the neighboring Sa'ad ad-Din Islands. In 1900, a quarantine station was built to accommodate persons in health quarantine, but it was ultimately not used fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Tadjoura
The Gulf of Tadjoura (; ) is a gulf or basin of the Indian Ocean in the Horn of Africa. It lies south of the straits of Bab-el-Mandeb, or the entrance to the Red Sea, at . The gulf has many fishing grounds, extensive coral reefs, and abundant pearl oysters. Most of its coastline is the territory of Djibouti, except for a short stretch on the southern shore, which is part of the territory of Somaliland. The Gulf’s other marine habitats include sea grass beds, salt pans and mangroves. History In August 1840, the conclusion of a treaty of friendship and commerce between the Sultan Mohammed bin Mohammed of Tadjoura and Commander Robert Moresby of the Indian Navy is tracking the sale of Moucha Island to Great Britain for ten sacks of rice. The sale will however follow any occupation. In 1887, Britain cedes sovereignty of the island to France at the same time it recognizes the French sphere of influence in the Gulf of Tadjoura, in exchange for the abandonment by France of any ri ...

Henry De Monfreid
Henry de Monfreid (14 November 1879 in Leucate – 13 December 1974) was a French adventurer and author. Born in Leucate, Aude, France, he was the son of artist painter Georges-Daniel de Monfreid and knew Paul Gauguin as a child. Monfreid was known for his travels in the Red Sea and the Horn of Africa coast from Tanzania to Aden, Yemen, the Arabian Peninsula and Suez, that he sailed in his various expeditions as adventurer, smuggler and gunrunner (during which he said he more than once escaped Royal Navy coast-guard cutters). Life In 1911, following in the footsteps of Arthur Rimbaud, Monfreid went to Djibouti, then a French colony, in order to trade coffee. He built a dhow for himself and used it to cross the Red Sea. He had many adventures, eventually prospered, bought a house near the shore in Obock cove, and had a big dhow, the ''Altair'' ("Soaring Eagle"), built by a local shipyard. Towards the end of the war, he settled with his family in Obock, away from prying e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter
Winter is the coldest season of the year in polar and temperate climates. It occurs after autumn and before spring. The tilt of Earth's axis causes seasons; winter occurs when a hemisphere is oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. In many regions, winter brings snow and freezing temperatures. The moment of winter solstice is when the Sun's elevation with respect to the North or South Pole is at its most negative value; that is, the Sun is at its farthest below the horizon as measured from the pole. The day on which this occurs has the shortest day and the longest night, with day length increasing and night length decreasing as the season progresses after the solstice. The earliest sunset and latest sunrise dates outside the polar regions differ from the date of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summer
Summer is the hottest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, the earliest sunrise and latest sunset occurs, daylight hours are longest and dark hours are shortest, with day length decreasing as the season progresses after the solstice. The date of the beginning of summer varies according to climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Timing From an astronomical view, the equinoxes and solstices would be the middle of the respective seasons, but sometimes astronomical summer is defined as starting at the solstice, the time of maximal insolation, often identified with the 21st day of June or December. By solar reckoning, summer instead starts on May Day and the summer solstice is Midsummer. A variable seasonal lag means that the meteorological centre of the season, which is based on average temperature patte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperature
Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measurement, measured with a thermometer. Thermometers are calibrated in various Conversion of units of temperature, temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), the latter being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible to extract energy as heat from a body at that temperature. Tem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, s ...

Islet
An islet is a very small, often unnamed island. Most definitions are not precise, but some suggest that an islet has little or no vegetation and cannot support human habitation. It may be made of rock, sand and/or hard coral; may be permanent or tidal (i.e. surfaced reef or seamount); and may exist in the sea, lakes, rivers or any other sizeable bodies of water. Definition As suggested by its origin ''islette'', an Old French diminutive of "isle", use of the term implies small size, but little attention is given to drawing an upper limit on its applicability. The World Landforms website says, "An islet landform is generally considered to be a rock or small island that has little vegetation and cannot sustain human habitation", and further that size may vary from a few square feet to several square miles, with no specific rule pertaining to size. Other terms * Ait (/eɪt/, like eight) or eyot (/aɪ(ə)t, eɪt/), a small island. It is especially used to refer t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zeila Archipelago
The Sa'ad ad-Din Islands ( so, Jasiirada Sacadadiin, ar, جزر سعد الدين), also Romanized as and known as the Zeila Archipelago, are a group of islands off the northern coast of Somaliland. They are situated near the ancient city of Zeila. The Zeila Archipelago is made of six small islands all of which are low-lying and have sandy beaches. The largest of these islands are '' Sacadin'' and '' Aibat'', which are six and nine miles off the coast of Zeila, respectively. There is also a lighthouse at Aibat. Etymology & History The name for the archipelago comes from the Sultan Sa'ad ad-Din II who was killed by the Emperor of Abyssinia on the main island in 1415. Along with his name, there are many different spellings for the island such as , , and . The archpeligo is also known as the ''Zeila Archipelago'' and the ''Sa'ad ad-Din group''. Legendary Arab explorer Ahmad ibn Mājid wrote of the archipelago and a few other notable landmarks and ports of the northern Somali ...

Coral Island
A coral island is a type of island formed from coral detritus and associated organic material. It occurs in tropical and sub-tropical areas, typically as part of a coral reef which has grown to cover a far larger area under the sea. Ecosystem Coral reefs are some of the oldest ecosystems on the planet, over geological time forming massive reefs of limestone. The reef environment supports more plant and animal species than any other habitat. Coral reefs are vital for life for multiple aspects some of which include structure, ecology, and nutrient cycles which all support biodiversity in the reefs. Coral reefs build massive calcareous skeletons that serve as homes for animals such as fish hiding inside the crooks and crannies of the reef and barnacles attaching themselves directly to the coral’s structure. The structures also help plants that need the sun to photosynthesize, by lifting the plants to the ocean’s surface where the sunlight can penetrate the water. The struct ...

Zeila
Zeila ( so, Saylac, ar, زيلع, Zayla), also known as Zaila or Zayla, is a historical port town in the western Awdal region of Somaliland. In the Middle Ages, the Jewish traveller Benjamin of Tudela identified Zeila (or Hawilah) with the Biblical location of Havilah. Most modern scholars identify it with the site of Avalites mentioned in the 1st-century Greco-Roman travelogue the ''Periplus of the Erythraean Sea'' and in Ptolemy, although this is disputed. The town evolved into an early Islamic center with the arrival of Muslims shortly after the Hijrah. By the 9th century, Zeila was the capital of the early Adal Kingdom and Ifat Sultanate in the 13th century; and also a capital for its successor state the Adal Sultanate, it would attain its height of prosperity a few centuries later in the 16th century. The city subsequently came under Ottoman and British protection in the 18th century. Up until recently Zeila was surrounded by a large wall with five gates: Bab al Sahil ...

Robert Moresby
Robert Moresby (15 June 1794 – 15 June 1854Some sources mention that he is thought to have died in 1863.) was a captain of the East India Company's Bombay Marine/Indian Navy who distinguished himself as a hydrographer, maritime surveyor and draughtsman. As a Lieutenant under Commander Thomas Elwon, Moresby was part of a two-ship exercise engaged (from 1829 to 1832) in charting the dangerous waters of the Red Sea. Later, he also charted some coralline archipelagoes of the Indian Ocean, such as the Maldives, Laccadives and Chagos in the 1820s and '30s. This work ensured that the route from Europe to the East Indies became viable for the new steam vessels. Robert Moresby was a son of Mr Fairfax Moresby of Lichfield, Staffs, late of India, where Fairfax Moresby had practised as a lawyer. Fairfax Moresby and his wife Mary Rotten had 6 boys and 3 girls, the eldest of whom was Sir Fairfax Moresby, Admiral of the British Fleet, and Commander in Chief, Channel Squadron and Pac ...
