Roncador Reef
Roncador Reef is a reef in Solomon Islands, south of Ontong Java Atoll and north of Santa Isabel Island. This submerged reef forms a small geographic group together with Nukumanu and Ontong Java, the two nearest atolls located further north. History This reef was first sighted by Europeans at the time of the Spanish expedition of Álvaro de Mendaña and Pedro Sarmiento de Gamboa Pedro Sarmiento de Gamboa (1532–1592) was a Spanish explorer, author, historian, mathematician, and astronomer. His birthplace is not certain and may have been Pontevedra, in Galicia, where his paternal family originated, or Alcalá de Henare ... on 1 February 1558. It was charted as ''Bajos de la Candelaria'' (shoals of Our Lady of Candlemas in Spanish). Its sighting was also reported by Spanish naval officer Francisco Mourelle de la Rúa on 22 January 1781 on board of frigate ''La Princesa''. He charted this reef as ''Peregrino Roncador'' (Snoring Pilgrim in Spanish).Landin Carrasco, Amancio ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solomon Islands
Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands. The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called ''"the Solomons"'' by those who later receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaita Province
Malaita Province is the most populous and one of the largest of the nine provinces of Solomon Islands. It is named after its largest island, Malaita (also known as "Big Malaita" or "Maramapaina"). Other islands include South Malaita Island (also called "Small Malaita" or "Maramasike"), Sikaiana Island, and Ontong Java Atoll. Britain defined its area of interest in the Solomons, including Malaita, and central government control of Malaita began in 1893, when Captain Gibson R.N., of , declared the southern Solomon Islands as a British Protectorate with the proclamation of the British Solomon Islands Protectorate. The provincial capital and largest urban center is Auki, which was established as the Administrative center for Malaita Province in 1909. Tourism is largely underdeveloped in Malaita; Auki is near to the Langa Langa Lagoon, which provides opportunities for snorkeling, and the villagers provide shell making demonstrations.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster reefs and sponge reefs, but the most massive and widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ontong Java Atoll
Ontong Java Atoll or Luangiua, (formerly ''Lord Howe Atoll'', not to be confused with Lord Howe Island) is one of the largest atolls on earth. Geographically it belongs to a scattered group of three atolls which includes nearby Nukumanu Atoll and the wholly submerged Roncador Reef located to the south. Description Administratively Ontong Java belongs to Solomon Islands. As an outlying part of Malaita Province, it forms the northernmost tract of land of this state, over north of Santa Isabel Island. The closest land, however, is Nukumanu Atoll, which lies only due north of Ontong Java's northern tip and, though historically closely related to Ontong Java, is now under the administration of Papua New Guinea. Ontong Java is roughly boot-shaped. The entire size of the atoll is , but there are only of land, spread out over 122 small islands. The islands are mostly low-lying coral formations, the highest elevation being . Approximately 2000 people live on the atoll. There are ...

Santa Isabel Island
Santa Isabel Island (also known as Isabel, Ysabel and Mahaga) is the longest in Solomon Islands, the third largest in terms of surface area, and the largest in the group of islands in Isabel Province. Location and geographic data Choiseul lies to the north-west, Malaita to the south-east. The Pacific Ocean lies to the north, and Guadalcanal (Isatabu) to the south. The highest point in Santa Isabel is Mount Sasari, . The Marutho river runs down Mount Sasari to the ocean at Hofi. Almost all the rivers or streams run from that centre point except for those at the other tip of the island on the Katova side. The administrative centre is Buala. The nearest airport is Fera Airport on neighbouring Fera Island. History The first European landing in the Solomon Islands archipelago was made at Santa Isabel Island, by the Spanish explorer Álvaro de Mendaña on 7 February 1568. It was charted as ''Santa Isabel de la Estrella'' (St. Elizabeth of the Star of Bethlehem in Spanish). A set ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nukumanu
The Nukumanu Islands, formerly the Tasman Islands, is an atoll of Papua New Guinea, located in the south-western Pacific Ocean, 4 degrees south of the Equator. Description Comprising a ring of more than twenty islets on a reef surrounding a large lagoon, Nukumanu's sandy islands are located on a strip of coral rising no more than above sea level. The main inhabited islands of Nukumanu are located on the eastern end of the atoll. Administratively Nukumanu is part of the Autonomous Region of Bougainville in Papua New Guinea, but it lies quite far away from the closest territory of Papua New Guinea proper, which is the coast of New Ireland island at to the west. The nearest land is Ontong Java Atoll, located only to the south of Nukumanu. The border between Papua New Guinea and the Solomon Islands runs between these neighboring atolls, which form a small geographic group together with the wholly submerged Roncador Reef at the southern end.

Álvaro De Mendaña De Neira
Álvaro de Mendaña y Neira (or Neyra) (1 October 1542 – 18 October 1595) was a Spanish navigator and discoverer, best known for two of the earliest recorded expeditions across the Pacific in 1567 and 1595. His voyages led to the discovery of the Marquesas, Cook Islands and Solomons among other archipelagos. Born in Congosto, in El Bierzo Region ( León), he was the nephew of Lope García de Castro, viceroy of Peru. Search for Terra Australis Between 1565 and 1605, three important Spanish voyages of exploration left Peru bound for the southwest Pacific. One inspiration for these voyages was Spanish soldier Pedro Sarmiento de Gamboa who arrived in Peru in 1557. Sarmiento de Gamboa developed an interest in Inca stories of gold and riches being collected from lands further to the west. Sarmiento's proposal for an expedition to find land in the Pacific was put to Governor Lope García de Castro, finding favour as it matched common Spanish belief in the existence of a great South ...

Presentation Of Jesus At The Temple
The Presentation of Jesus at the Temple (or ''in the temple'') is an early episode in the life of Jesus Christ, describing his presentation at the Temple in Jerusalem, that is celebrated by many churches 40 days after Christmas on Candlemas, or the "Feast of the Presentation of Jesus". The episode is described in chapter 2 of the Gospel of Luke in the New Testament. Within the account, "Luke's narration of the Presentation in the Temple combines the purification rite with the Jewish ceremony of the redemption of the firstborn ()." In the Eastern Orthodox Church, the Presentation of Jesus at the temple is celebrated as one of the twelve Great Feasts, and is sometimes called ''Hypapante'' (, "meeting" in Greek). The Orthodox Churches which use the Julian Calendar celebrate it on 15 February, and the Armenian Church on 14 February. In Western Christianity, the ''Feast of the Presentation of the Lord'' is also known by its earlier name as the ''Feast of the Purification of the ...
