Lac Rose
Lac Rose (meaning Pink Lake) lies north of the Cap Vert peninsula of Senegal, some 30 km (18 miles) north-east of the capital, Dakar, in northwest Africa. It is named for its pink waters caused by ''Dunaliella salina'' algae and is known for its high salt content, up to 40% in some areas. Description The lake is separated from the Atlantic Ocean only by a narrow corridor of dunes, and is named for its pink waters, which are caused by ''Dunaliella salina'' algae. The algae produce a red pigment to help them absorb sunlight, which gives them energy to create ATP. The color is particularly visible during the dry season (from November to May) and less visible during the rainy season (June to October). Magenta coloured samphire bushes flourish in the lake’s white sandbanks; the sand dunes are terra-cotta-coloured. Salt The lake is known for its high salt content (up to 40% in some areas), which is mainly due to the ingress of seawater and its subsequent evaporation. Like ...

Cap Vert
Cap-Vert, or the Cape Verde Peninsula, is a peninsula in Senegal and the westernmost point of the continent of Africa and of the Afro-Eurasia mainland. Portuguese explorers called it Cabo Verde or "Green Cape". The Cape Verde islands, further west, are named after the cape. Dakar, the capital of Senegal, occupies parts including its southern tip. Formed by a combination of volcanic offshore islands and a land bridge produced by coastal currents, the cape projects into the Atlantic Ocean, bending back to the southeast at its tip. Exposure to southwesterly winds contributes to Cape Verde's seasonal verdant appearance, in contrast to the undulating yellow dunes to the north. The peninsula is shaped like a triangle (about per side), with the base of the triangle roughly along the north and its apex on the south, near Dakar. Near Pointe des Almadies, the north-western tip of the cape, lies Léopold Sédar Senghor International Airport, which was used as a transatlantic ferrying p ...

Dead Sea
The Dead Sea ( he, יַם הַמֶּלַח, ''Yam hamMelaḥ''; ar, اَلْبَحْرُ الْمَيْتُ, ''Āl-Baḥrū l-Maytū''), also known by other names, is a salt lake bordered by Jordan to the east and Israel and the West Bank to the west. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River. As of 2019, the lake's surface is below sea level, making its shores the lowest land-based elevation on Earth. It is deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2% (in 2011), it is one of the world's saltiest bodies of water – 9.6 times as salty as the ocean – and has a density of 1.24 kg/litre, which makes swimming similar to floating. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea's main, northern basin is long and wide at its widest point. The Dead Sea has attracted visitors from around the Mediterranean Basin for th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Extreme E
Extreme E is an FIA-sanctioned international off-road racing series that uses spec silhouette electric SUVs to race in remote parts of the world, such as the Saudi Arabian desert or the Arctic. All racing locations are chosen to raise awareness for some aspects of climate change and Extreme E maintains a "Legacy Programme" which intends to provide social and environmental support for those locations. The series also promotes gender equality in motorsport by mandating that all teams consist of a female and a male driver who share equal driving duties. The first season began with the Desert X-Prix in Saudi Arabia in April 2021. Team X44 is the defending champion. History Preparations Extreme E began in 2018 as a project led by Formula E founder Alejandro Agag and former driver Gil de Ferran. The series was presented to the public in January 2019 with an event in London. The announcement took place on board of the ship ''St Helena'' which was to serve as "floating paddock" of th ...

Dakar Rally
The Dakar Rally (or simply "The Dakar"; formerly known as the "Paris–Dakar Rally") is an annual rally raid organised by the Amaury Sport Organisation. Most events since the inception in 1978 were staged from Paris, France, to Dakar, Senegal, but due to security threats in Mauritania, which led to the cancellation of the 2008 rally, events from 2009 to 2019 were held in South America. Since 2020, the rally has been held in Saudi Arabia. The event is open to amateur and professional entries, amateurs typically making up about eighty percent of the participants. The rally is an off-road endurance event. The terrain that the competitors traverse is much tougher than that used in conventional rallying, and the vehicles used are typically true off-road vehicles and motorcycles, rather than modified on-road vehicles. Most of the competitive special sections are off-road, crossing dunes, mud, Cymbopogon schoenanthus, camel grass, rocks, and erg (landform), erg among others. The dist ...

World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. A ...

Brackish Water
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gr ...

Blackchin Tilapia
The blackchin tilapia (''Sarotherodon melanotheron'') is a species of cichlid native to coastal west Africa. It is a paternal mouthbrooder which has been introduced to Asia and North America. In the Philippines, it is also informally called ''gloria'' or ''tilapiang arroyo'' after former Philippine President Gloria Macapagal-Arroyo because of its small size and mole-like dark pigmentation under its lower jaw, resembling that of the short stature and mole on the former president's left cheek. Description The blackchin tilapia, is pale in colour, that colour varying in shades including light blue, orange and golden yellow which normally has dark patches on the chin of adults. It also normally has dark colouration on the posterior edge of the gill and on the tips of the soft rays of the dorsal fin. The body is typically marked with irregular bars, spots or splotches. It has a small mouth which is equipped with as many as a few hundred tiny teeth which are arranged in 3-6 rows. They ...

Salinity
Salinity () is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ions ...

Lake Retba (Lac Rose), Worker Is Digging The Salt In The Lake
Lake Retba, also known as Lac Rose (meaning "pink lake"), lies north of the Cap Vert peninsula in Senegal, some north-east of the capital, Dakar, in northwest Africa. It is named for its pink waters caused by ''Dunaliella salina'' algae and is known for its high salt content, up to 40% in some areas. Its colour is usually particularly strong from late January to early March, during the dry season; however, flooding in September 2022 not only disrupted salt harvesting activities on the lake, but because it caused the lake to lose its colour, had a negative effect on tourism. The lake is under consideration by UNESCO as a World Heritage Site. Description The lake is situated north-east of Dakar, separated from the Atlantic Ocean only by a narrow corridor of dunes, and is named for its pink waters, which are caused by ''Dunaliella salina'' algae. The algae produce a red pigment to help them absorb sunlight, which gives them energy to create ATP, a nucleotide that is necessary ...

Thieboudienne
''Tiep'' or ''thieb'' is a traditional dish from Senegal that is also consumed in Guinea-Bissau, Guinea, Mali, Mauritania, and The Gambia. It is the national dish in Senegal. The version of tiep called ''thieboudienne'' or ''chebu jen'' ( wo, ceebu jën; french: thiéboudiène) is prepared with fish, rice and tomato sauce cooked in one pot. There are also ''tiep yappa'' (with meat) and ''tiep ganaar'' (with chicken). Additional ingredients often include onions, carrots, cabbage, cassava, hot pepper, lime and peanut oil, and stock cubes. Historically, tiep is commonly attributed to the city of Saint-Louis, in the nineteenth century. The name of the dish comes from Wolof words meaning 'rice' () and 'fish' (). In Pulaar it is known as ('rice and fish'). It is served on large trays with the rice on the bottom and the fish, usually white grouper (''Epinephelus aeneus''), and the vegetables, many of them whole, placed in the center. Traditionally it is eaten in a large communal di ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
