Jaffna Lagoon
Jaffna Lagoon is a large lagoon off Jaffna District and Kilinochchi District, northern Sri Lanka. The lagoon is surrounded by the densely populated Jaffna Peninsula containing palmyra palms, coconut plantations, and rice paddies. There are numerous fishing villages and some salt pans. The lagoon has extensive mudflats, seagrass beds and some mangroves. The lagoon attracts a wide variety of water birds including American flamingoes, ducks, gulls, terns and other shorebirds. Jaffna Lagoon Jaffna Lagoon is a shallow coastal stretch of water between the Jaffna and the Kilinochchi Districts in northern Sri Lanka. It is located between the longitudes of 79°54E and 80°20E, and the latitudes of 9°30N and 9°50N, and connected to Palk Bay through a channel to the west. It is connected to two internal lagoons, Vadamarachchi Lagoon and Uppu Aru Lagoon, and the external Chundikkulam Lagoon (sometimes known as Elephants Pass Lagoon). The lagoons receive fresh water from their catchment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove
A mangrove is a shrub or tree that grows in coastal saline water, saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are ad ...

Seagrass Meadow
A seagrass meadow or seagrass bed is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries. Seagrasses are flowering plants with stems and long green, grass-like leaves. They produce seeds and pollen and have roots and rhizomes which anchor them in seafloor sand. Seagrasses form dense underwater meadows which are among the most productive ecosystems in the world. They provide habitats and food for a diversity of marine life comparable to that of coral reefs. This includes invertebrates like shrimp and crabs, cod and flatfish, marine mammals and birds. They provide refuges for endangered species such as seahorses, turtles, and dugongs. They function as nursery habitats for shrimps, scallops and many commercial fish species. Seagrass meadows provide coastal storm protection by the way their leaves absorb energy from waves as they hit the coast. They keep coastal waters healthy ...

Land Mine
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Landmines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their potential as indiscriminate weapons. They can remain dangerous many years after a conflict has ended, harming civilians and the economy. Seventy-eight countries are contaminated with land mines and 15,000–20,000 people are killed every year while many more are injured. Approximately 80% of land mine casualties are civilians, with children as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liberation Tigers Of Tamil Eelam
The Liberation Tigers of Tamil Eelam (LTTE; ta, தமிழீழ விடுதலைப் புலிகள், translit=Tamiḻīḻa viṭutalaip pulikaḷ, si, දෙමළ ඊළාම් විමුක්ති කොටි, translit=Damiḷa īḷām vimukthi koṭi; also known as the Tamil Tigers) was a Tamil militant organization that was based in northeastern Sri Lanka. The LTTE fought to create an independent Tamil state called Tamil Eelam in the north-east of the island, due to the continuous discrimination and violent persecution against Sri Lankan Tamils by the Sinhalese dominated Sri Lankan Government.T. Sabaratnam, Pirapaharan, Volume 1, Introduction (2003)T. Sabaratnam, Pirapaharan, Volume 1, Chapter 1: Why didn't he hit back? (2003) Violent persecution erupted in the form of the 1956 and 1958 anti-Tamil pogroms which were carried out by majority Sinhalese mobs often with state support following the passing of the 1956 Sinhala Only Act.

Palk Bay
Palk Bay is a semi-enclosed shallow water body between the southeast coast of India and Sri Lanka, with a water depth maximum of 13 m. Palk Bay is located between 8° 50′ and 10° North latitudes and 78° 50′ and 80° 30′ East longitudes. The width of Palk Bay ranges from 57 to 107 km and the length is around 150 km. Palk Bay is considered to be one amongst the major sinks for sediments along with Gulf of Mannar. Sediments discharged by rivers and transported by the surf currents as littoral drift settle in this sink. Few scientists have tried to understand the wave characteristics within the Palk Bay. In the southern regions close to Dhanushkodi, wind seas dominate. The north-eastern region of Palk Bay is exposed to the Bay of Bengal through the shallow Palk Strait and hence the swells can enter the Palk Bay through this opening. To the south of Palk Bay, Adam's Bridge separates Palk Bay from the Gulf of Mannar. Despite being a very shallow channel, Wave effe ...

Wader
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Tern
Terns are seabirds in the family Laridae that have a worldwide distribution and are normally found near the sea, rivers, or wetlands. Terns are treated as a subgroup of the family Laridae which includes gulls and skimmers and consists of eleven genera. They are slender, lightly built birds with long, forked tails, narrow wings, long bills, and relatively short legs. Most species are pale grey above and white below, with a contrasting black cap to the head, but the marsh terns, the Inca tern, and some noddies have dark plumage for at least part of the year. The sexes are identical in appearance, but young birds are readily distinguishable from adults. Terns have a non-breeding plumage, which usually involves a white forehead and much-reduced black cap. Terns are long-lived birds and are relatively free from natural predators and parasites; most species are declining in numbers due directly or indirectly to human activities, including habitat loss, pollution, disturbance, an ...

Gull
Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns and skimmers and only distantly related to auks, and even more distantly to waders. Until the 21st century, most gulls were placed in the genus ''Larus'', but that arrangement is now considered polyphyletic, leading to the resurrection of several genera. An older name for gulls is mews, which is cognate with German ''Möwe'', Danish ''måge'', Swedish ''mås'', Dutch ''meeuw'', Norwegian ''måke''/''måse'' and French ''mouette'', and can still be found in certain regional dialects. Gulls are typically medium to large in size, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls; stout, longish bills; and webbed feet. Most gulls are ground-nesting carnivores which take live food or scavenge opportunistically, particularly the ''Larus'' species. Live food often includes crustac ...
