Yanar Dag (Azerbaijani: "Yanar Dağ" , meaning "burning mountain") is a natural gas fire which blazes continuously on a hillside on the Absheron Peninsula on the Caspian Sea near Baku, the capital of Azerbaijan (a country which itself is known as "the Land of Fire").
 Flames jet into the air 3 m from a thin, porous sandstone layer.
 Administratively, Yanar Dag belongs to Absheron District of Azerbaijan.
A Mesophotic coral reef, from "meso" meaning middle and "photic" meaning light, is characterised by the presence of both light dependent coral and algae, and organisms that can be found in water with low light penetration.
 They normally grow between 30-40 m, and up to 150 m in tropical and subtropical water.
 The most common species at the mesophotic level are corals, sponges and algae.
 The corals ranges can overlap with Deep-water coral but are distinguished by the presence of zooxanthellae and their requirement for light.
 They can also be thought of as part of shallow water coral ecosystems, and a crossover of coral species between the two is common.
 It is thought that these corals could be used as sources for reseeding shallow water coral species.
Lökbatan Mud Volcano (Azerbaijani: "Lökbatan palçıq vulkanı" ), also known as Lok-Batan Mud Cone, is a mud volcano located in Absheron peninsula in the Absheron District of Azerbaijan.
 The mud volcano erupted in 1977 and again, on October 10, 2001, when it produced large flames many tens of meters high.
 The area since 1998 submitted to UNESCO's World Heritage Site tenative list.
The shallow water equations (also called Saint-Venant equations in its unidimensional form, after Adhémar Jean Claude Barré de Saint-Venant) are a set of hyperbolic partial differential equations (or parabolic if viscous shear is considered) that describe the flow below a pressure surface in a fluid (sometimes, but not necessarily, a free surface).
 The shallow water equations can also be simplified to the commonly used 1-D Saint-Venant equation.
Shallow water fishing is one type of the many types of fishing there is.
 Shallow can mean many different things; shallow lakes, shallow rivers, and most common to fishermen is the shallow ponds with high concentrations of moss.
 There are many different baits and fishing lures for shallow water fishing such as, "Skitter Pop, Skitter Walk, Pencil Popper, Popper, Slim Dog, Z-Top, Turbo Toad Buzz Baits, Locust, Frogs, Jerk Baits, etc.
Shallow Water Absheron Peninsula (SWAP) is a PSA signed on 22 December 2014 between SOCAR and BP on the joint exploration and development of potential prospects in the shallow water area around the Absheron peninsula.
 The contract was ratified by the Azerbaijani parliament on 14 April 2015.
Absheron Rayon (Azerbaijani: "Abşeron" , Russian: Апшерон ), also spelled as Apsheron, is a rayon of Azerbaijan demarcated in 1963.
 Although it shares the same name as the Absheron Peninsula, the area covered by the rayon is not conterminous, being further west and mostly inland.
BP P.L.C., formerly British Petroleum, is a British multinational oil and gas company headquartered in London.
 It is one of the world's seven oil and gas "supermajors", whose performance in 2012 made it the world's sixth-largest oil and gas company, the sixth-largest energy company by market capitalization and the company with the world's twelfth-largest revenue (turnover).
 It is a vertically integrated company operating in all areas of the oil and gas industry, including exploration and production, refining, distribution and marketing, petrochemicals, power generation and trading.
 It also has renewable energy interests in biofuels and wind power.
A pirogue ( or ), also called a piragua or piraga, can be one of several kinds of small boats.
 One kind is associated particularly with the Cajuns of the Louisiana marsh.
 The early Cajun pirogues were cypress dugouts but today they are usually flat-bottomed boats. Pirogues are not usually intended for overnight travel but are light and small enough to be easily taken onto land.
 The design also allows the pirogue to move through the very shallow water of marshes and be easily turned over to drain any water that may get into the boat.
 A pirogue has "hard chines" which means that instead of a smooth curve from the gunwales to the keel, there is often a flat bottom which meets the plane of the side.
 The pirogue is usually propelled by paddles that have one blade (as opposed to a kayak paddle, which has two).
 It can also be punted with a push pole in shallow water.
 Small sails can also be employed.
 Outboard motors are increasingly being used in many regions.
 In West Africa they were used as traditional fishing boats.
Boyukshor (Azerbaijani: "Böyük Şor gölü" ), also spelled separately Boyuk Shor (in translation refers to "Big Salty Waters") is the second largest lake of Azerbaijan and largest on Absheron Peninsula.
 It is located in the center of the Absheron peninsula, on the boundaries of Binagadi, Sabunchu and Narimanov raions of the city of Baku.
