Misión Tiburón
Misión Tiburón is a non profit organisation established in 2009, based on the Pacific coast of Costa Rica. Founded by marine biologists and conservationists Ilena Zanella and Andres Lopez, the organisation focuses on marine research concerning sharks, sea turtles and rays as well as education programs targeted at local coastal communities. Operations Misión Tiburón has its operations center in Guanacaste Province, in the North Pacific of Costa Rica. Since 2019, Misión Tiburón also carries out regular shark tagging operations from Golfito, in southern Costa Rica. The organisation focuses its efforts on three main areas: marine education, marine research and political and social advocacy. The main aim of its marine education operations is to raise awareness within Costa Rica as well as globally of the importance of sharks in the oceans, the threats that they are facing and their sharp population decline. The scientific marine research area focuses on sharks and other marine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation Organization
An environmental organization is an organization coming out of the conservation or environmental movements that seeks to protect, analyse or monitor the environment against misuse or degradation from human forces. In this sense the environment may refer to the biophysical environment or the natural environment. The organization may be a charity, a trust, a non-governmental organization, a governmental organization or an intergovernmental organization. Environmental organizations can be global, national, regional or local. Some environmental issues that environmental organizations focus on include pollution, plastic pollution, waste, resource depletion, human overpopulation and climate change. Intergovernmental organizations Global organizations * Global Alliance on Health and Pollution (GAHP) * Earth System Governance Project (ESGP) * School strike for climate or Fridays for Future (FFF) * Global Green Growth Institute (GGGI) * Intergovernmental Panel on Climate Change (I ...

Undersea Mountain Range
Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a ''mid-ocean ridge''. In contrast, if formed by past above-water volcanism, they are known as a ''seamount chain''. The largest and best known undersea mountain range is a mid-ocean ridge, the Mid-Atlantic Ridge The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North Ame .... It has been observed that, "similar to those on land, the undersea mountain ranges are the loci of frequent volcanic and earthquake activity".Martin F. Price, Alton C. Byers, Donald A.

Sylvia Earle
Sylvia Alice Earle (born August 30, 1935) is an American marine biologist, oceanographer, explorer, author, and lecturer. She has been a National Geographic Explorer at Large (formerly Explorer in Residence) since 1998. Earle was the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration, and was named by ''Time Magazine'' as its first Hero for the Planet in 1998. Earle is part of the group Ocean Elders, which is dedicated to protecting the ocean and its wildlife. Earle gained a large amount of publicity when she was featured in ''Seaspiracy'' (2021), a Netflix Original documentary by British filmmaker Ali Tabrizi. Earle eats a vegetarian diet. She describes the chemical buildup in carnivorous fish, the 90% depletion of populations of large fish, and references the health of oceans in her dietary decision. Also, she describes the seafood industry as “factory ships vacuuming up fish and everything else in their path. That’s like using bul ...

Hope Spots
Hope Spots are ecologically unique areas of the ocean designated for protection under a global conservation campaign overseen by Mission Blue, a non-profit organization founded by Sylvia Earle with her 2009 TED prize wish. Hope Spots can be Marine Protected Areas (MPA) that need attention or new sites. They are chosen for their contributions to biodiversity, the carbon sink, and important habitat. Hope Spot status is intended to alleviate the pressures human resource extraction places on the ocean by making the site higher priority to become an MPA, where resource extraction, like fishing and drilling, may be forbidden under law. There are 140 Hope Spots worldwide (as of June,2022). An additional 22 nominations for Hope Spots are currently under consideration and three nominations have been deferred. At the time of Earle's wish, less than 1% of the ocean was protected. Earle advocated for the creation of a system of parks like the national park system in the United States. The go ...

Rainforest Trust
Rainforest Trust is a US-based nonprofit environmental organization focused on the purchase and protection of tropical lands to strategically conserve threatened species. Founded in 1988, Rainforest Trust was formerly known as World Parks Endowment. In 2006, then World Parks Endowment affiliated itself with World Land Trust, a UK-based nonprofit environmental organization, and became World Land Trust-US, as both organizations were dedicated to minimizing their costs in order to allow donated funds to flow to habitat conservation projects on the ground. On September 16, 2013, because of diverging modus operandi, and as part of celebrating the organization's 25th anniversary, the World Land Trust-US changed its name to Rainforest Trust. Rainforest Trust supports the purchase of large tracts of land by local NGOs working across tropical Asia, Africa, and Latin America for the purposes of protecting it, in a fashion similar to the Nature Conservancy by making use of land trusts.

National System Of Conservation Areas
National System of Conservation Areas (SINAC, es, Sistema Nacional de Áreas de Conservación) is part of the Ministry of Environment and Energy (MINAE) of Costa Rica. It is the administrator for the nation's national parks, conservation areas, and other protected natural areas. Created in 1994, it combined three previously separate organisations that had managed laws relating to national parks, wildlife, and forestry. Scope SINAC oversees over 160 protected areas, of which 30 are designated National Parks. Other areas are designated wildlife refuges, biological reserves, national monuments, forest reserves, national wetlands, and protected zones. The entire country of 12,596,690 acres (50,977 km²) is under the jurisdiction of eleven large Conservation Areas which were created in 1998, overseen by divisions of SINAC. Over 25% of the national territory, i.e. 3,221,636 acres (13,037 km²) is included in the national parks, refuges, and protected zones within these el ...

Salt Water
Saline water (more commonly known as salt water) is water that contains a high concentration of dissolved salts (mainly sodium chloride). On the United States Geological Survey (USGS) salinity scale, saline water is saltier than brackish water, but less salty than brine. The salt concentration is usually expressed in parts per thousand (permille, ‰) and parts per million (ppm). The USGS salinity scale defines three levels of saline water. The salt concentration in slightly saline water is 1,000 to 3,000 ppm (0.1–0.3%); in moderately saline water is 3,000 to 10,000 ppm (0.3–1%); and in highly saline water is 10,000 to 35,000 ppm (1–3.5%). Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water. The saturation level is only nominally dependent on the temperature of the water. At one liter of water can dissolve about 357 grams of salt, a concentration of 26.3% w/w. At boiling () the amount that can be dissolved in ...

Bull Shark
The bull shark (''Carcharhinus leucas''), also known as the Zambezi shark (informally zambi) in Africa and Lake Nicaragua shark in Nicaragua, is a species of requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers. It is known for its aggressive nature, and presence mainly in warm, shallow brackish and freshwater systems including estuaries and lower reaches of rivers. Bull sharks are euryhaline and can thrive in both salt and fresh water. They are known to travel far up rivers, and have been known to travel up the Mississippi River as far as Alton, Illinois, about from the ocean, but few freshwater interactions with humans have been recorded. Larger-sized bull sharks are probably responsible for the majority of nearshore shark attacks, including many incidents of shark bites attributed to other species. Unlike the river sharks of the genus '' Glyphis'', bull sharks are not true freshwater sharks, despite their ability to survive in freshwa ...

Cocos Island National Park
Cocos Island ( es, Isla del Coco) is an island in the Pacific Ocean administered by Costa Rica, approximately southwest of the Costa Rican mainland. It constitutes the 11th of the 13 districts of Puntarenas Canton of the Province of Puntarenas. With an area of approximately , the island is more or less rectangular in shape. It is the southernmost point of geopolitical North America if non-continental islands are included. The entirety of Cocos Island has been designated a Costa Rican National Park since 1978, and has no permanent inhabitants other than Costa Rican park rangers. Surrounded by deep waters with counter-currents, Cocos Island is admired by scuba divers for its populations of hammerhead sharks, rays, dolphins and other large marine species. The wet climate and oceanic qualities give Cocos an ecological character that is not shared with either the Galápagos Archipelago or any of the other islands (for example, Malpelo, Gorgona or Coiba) in the eastern Pacific O ...

Coral Reefs
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of Colony (biology), colonies of coral polyp (zoology), polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the Class (biology), class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fis ...

Whitetip Reef Shark
The whitetip reef shark (''Triaenodon obesus'') is a species of requiem shark, in the family Carcharhinidae, and the only member of its genus. A small shark that does not usually exceed in length, this species is easily recognizable by its slender body and short but broad head, as well as tubular skin flaps beside the nostrils, oval eyes with vertical pupils, and white-tipped dorsal and caudal fins. One of the most common sharks found on Indo-Pacific coral reefs, the whitetip reef shark occurs as far west as South Africa and as far east as Central America. It is typically found on or near the bottom in clear water, at a depth of . During the day, whitetip reef sharks spend much of their time resting inside caves. Unlike other requiem sharks, which rely on ram ventilation and must constantly swim to breathe, this shark can pump water over its gills and lie still on the bottom. At night, whitetip reef sharks emerge to hunt bony fishes, crustaceans, and octopus in groups, their elo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
