Sir Abu Nu'ayr
Sir Abu Nuayr (), also known as Sir Bu Nuayr (), or Sir al Qawasim (; also romanized as Sir Abu Neir, Sir Bu Nair or Sir Bu Nuair) is an island in the Persian Gulf. Geography Lying off the coast of the Emirate of Abu Dhabi, roughly north of Abu Dhabi city, and west of Dubai, it belongs to the Emirate of Sharjah, United Arab Emirates. Geology The island is almost perfectly round with a diameter of , and a long extension at its southeast end, making the shape of the whole island appear as a drop. The island is a salt-piercement structure formed by the movement of late Neoproterozoic to Early Cambrian Hormuz Formation salt. The salt has moved progressively upward, puncturing through the younger overlying strata to create a salt dome structure. Surface expressions are composed of evaporite rocks, plus igneous rocks and quartzitic sandstone. Environment The island, an environmentally protected area under the Sharjah Environment and Protected Areas Authority (EPAA), has been regi ...

International Space Station
The International Space Station (ISS) is a large space station that was Assembly of the International Space Station, assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), European Space Agency, ESA (Europe), JAXA (Japan), and Canadian Space Agency, CSA (Canada). As the largest space station ever constructed, it primarily serves as a platform for conducting scientific experiments in microgravity and studying the space environment. The station is divided into two main sections: the Russian Orbital Segment (ROS), developed by Roscosmos, and the US Orbital Segment (USOS), built by NASA, ESA, JAXA, and CSA. A striking feature of the ISS is the Integrated Truss Structure, which connect the station’s vast system of solar panels and Spacecraft thermal control, radiators to its pressurized modules. These modules support diverse functions, including scientific research, crew habitation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evaporite
An evaporite () is a water- soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution. There are two types of evaporite deposits: marine, which can also be described as ocean deposits, and non-marine, which are found in standing bodies of water such as lakes. Evaporites are considered sedimentary rocks and are formed by chemical sediments. Formation Although all water bodies on the surface and in aquifers contain dissolved salts, the water must evaporate into the atmosphere for the minerals to precipitate. For this to happen, the water body must enter a restricted environment where water input into this environment remains below the net rate of evaporation. This is usually an arid environment with a small drainage basin fed by a limited input of water. When evaporation occurs, the remaining water is enriched in salts, and they precipitate after the water becomes saturated. Depositional environments ...

Southeast
The points of the compass are a set of horizontal, Radius, radially arrayed compass directions (or Azimuth#In navigation, azimuths) used in navigation and cartography. A ''compass rose'' is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degree (angle), degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and northwest—each located halfway between two cardinal directions. Some disciplines such as meteorology and navigation further divide the compass with additional azimuths. Within European tradition, a fully defined compass has 32 "points" (and any finer subdivisions are described in fractions of points). Compass points or compass directions are valuable in that they allow a user to refer to a specific azimuth in a Colloquialism, colloquial fashion, without having to compute or remember degrees. Designations The names of the compass point directions follow these r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harbour
A harbor (American English), or harbour (Commonwealth English; see American and British English spelling differences#-our, -or, spelling differences), is a sheltered body of water where ships, boats, and barges can be Mooring, moored. The term ''harbor'' is often used interchangeably with ''port'', which is a man-made facility built for loading and unloading Watercraft, vessels and dropping off and picking up passengers. Harbors usually include one or more ports. Alexandria Port in Egypt, meanwhile, is an example of a port with two harbors. Harbors may be natural or artificial. An artificial harbor can have deliberately constructed breakwater (structure), breakwaters, sea walls, or jetties or they can be constructed by dredging, which requires maintenance by further periodic dredging. An example of an artificial harbor is Long Beach Harbor, California, United States, which was an array of salt marshes and tidal flats too shallow for modern merchant ships before it was first ...

Bridled Tern
The bridled tern (''Onychoprion anaethetus'')Sometimes the name is (wrongly?) spelled as ''S. anaestheta'', for instance in: is a seabird of the family Laridae. It is a bird of the tropical oceans. The scientific name is from Ancient Greek. The genus comes from ' meaning "claw" or "nail", and , meaning "saw". The specific ''anaethetus'' means "senseless, stupid". Description This is a medium-sized tern, at 30–32 cm in length and with a 77–81 cm wingspan similar to the common tern in size, but more heavily built. The wings and deeply forked tail are long, and it has dark grey upperparts and white underparts. The forehead and eyebrows are white, as is a striking collar on the hindneck. It has black legs and bill. Juvenile bridled terns are scaly grey above and pale below. This species is unlikely to be confused with any tern apart from the similarly dark-backed sooty tern and the spectacled tern from the Tropical Pacific. It is paler-backed than that sooty, (but n ...

Sooty Gull
The sooty gull (''Ichthyaetus hemprichii'') is a species of gull in the family Laridae, also known as the Aden gull or Hemprich's gull. It is found in Bahrain, Djibouti, Egypt, Eritrea, India, Iran, Israel, Jordan, Kenya, Lebanon, Maldives, Mozambique, Oman, Pakistan, Palestine, Qatar, Saudi Arabia, Somalia, Sri Lanka, Sudan, Tanzania, United Arab Emirates, and Yemen. As is the case with many gulls, it has traditionally been placed in the genus ''Larus''. The sooty gull is named in honour of the German naturalist Wilhelm Hemprich who died in 1825 while on a scientific expedition to Egypt and the Middle East with his friend Christian Gottfried Ehrenberg.Bauer, A. M. (2000) 'The Symbolae Physicae and the herpetology of Hemprich and Ehrenberg’s expedition to Egypt and the Middle East" '' International Society for the History and Bibliography of Herpetology Newsletter and Bulletin'' 2(1): pp. 8–16 Distribution and habitat The sooty gull is native to the Red Sea, the Gulf of ...

Socotra Cormorant
The Socotra cormorant (''Phalacrocorax nigrogularis'') is a threatened species of cormorant that is endemic to the Persian Gulf and the south-east coast of the Arabian Peninsula. It is also sometimes known as the Socotran cormorant or, more rarely, as the Socotra shag. Individuals occasionally migrate as far west as the Red Sea coast. Despite its name, it was only confirmed in 2005 that it breeds on the Socotra islands in the Indian Ocean.BirdLife International (2011). Species Factsheet: Phalacrocorax nigrogularis.' Retrieved 5 October 2011. The Socotra cormorant is an almost entirely blackish bird with a total length of about . In breeding condition, its forecrown has a purplish gloss and its upperparts have a slaty-green tinge, there are a few white plumes around the eye and neck and a few white streaks at the rump.

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Wetland
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor ( anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' ar ...
