Quintana Roo Speleological Survey
The Quintana Roo Speleological Survey (QRSS) was established in 1990 for the safe exploration, survey and cartography of the underwater and dry caves and cenotes of Quintana Roo, Mexico, supported by the National Speleological Society. The survey principally acts as a data repository for explored sites within the state of Quintana Roo and distributes summary statistical tables through its webpage, which as of February, 2011 included 208 underwater cave systems with a total surveyed length of , and 50 caves above the water table with a total length of . The geographical area for the data archived in the QRSS is essentially the whole of the state of Quintana Roo, which extends along the Caribbean coast of the Yucatán Peninsula, from Cancun and south to the capital of Chetumal situated on the border with Belize. The explosive urban and tourism based development within the Riviera Maya The Riviera Maya () is a tourism and resort district south of Cancun, Mexico. It straddles th ...

Cave
Caves or caverns are natural voids under the Earth's Planetary surface, surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called Caving, ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sedime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Costa Maya
Costa Maya is a small tourist region in the municipality of Othón P. Blanco in the state of Quintana Roo, Mexico, the only state bounded by the Caribbean Sea to its east. This municipality is close to Chetumal (capital of the state) on the border with Belize. The area was generally undeveloped but has been growing rapidly since construction of a large pier to accommodate cruise ships. Costa Maya is also the name of a subdivision near the village of Mahahual. The beach extends from Xcalak in the south to the southern border of Sian Ka'an in the north, a distance of approximately . Xcalak is approximately south of the Costa Maya cruise port, and the fishing village of Mahahual is only about away. Cruise ships can easily be seen from the village. Mahahual has soft sand beaches, grass thatched palapas, and a coral reef a short distance off-shore called Banco Chinchorro, as well as several bars, restaurants, and shops. A new development called New Mahahual is being created dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-profit Organizations Based In Mexico
A nonprofit organization (NPO), also known as a nonbusiness entity, nonprofit institution, not-for-profit organization, or simply a nonprofit, is a non-governmental (private) legal entity organized and operated for a collective, public, or social benefit, as opposed to an entity that operates as a business aiming to generate a profit for its owners. A nonprofit organization is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. Depending on the local laws, charities are regularly organized as non-profits. A host of organizations may be non-profit, including some political organizations, schools, hospitals, business associations, churches, foundations, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit en ...

Natural History Of Quintana Roo
Nature is an inherent character or constitution, particularly of the ecosphere or the universe as a whole. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright separate and even superior to nature. During the advent of modern scientific method in the last several centuries, nature became the passive reality, organized and moved by divine laws. With the Industrial Revolution, nature increasingly became seen as the part of reality deprived from intentional intervention: it was hence considered as sacred by some traditions (Rousseau, American transcendentalism) or a mere decorum for divine providence or human history (Hegel, Marx). However, a vitalist vision of nature, closer to the pre-Socratic one, got reborn at the same time, especially after Charles Darwin. Within the various uses of the word t ...

Geography Of Quintana Roo
Quintana Roo, officially the Free and Sovereign State of Quintana Roo, is one of the 31 states which, along with Mexico City, constitute the 32 federal entities of Mexico. It is divided into 11 municipalities, and its capital city is Chetumal. Quintana Roo is located on the eastern part of the Yucatán Peninsula and is bordered by the states of Campeche to the west and Yucatán to the northwest, and by the Orange Walk and Corozal districts of Belize, along with an offshore borderline with Belize District to the south. As Mexico's easternmost state, Quintana Roo has a coastline to the east with the Caribbean Sea and to the north with the Gulf of Mexico. The state previously covered and shared a small border with Guatemala in the southwest of the state. However, in 2013, Mexico's Supreme Court of Justice of the Nation resolved the boundary dispute between Quintana Roo, Campeche, and Yucatán stemming from the creation of the Calakmul municipality by Campeche in 1997, siding wi ...

Speleology
Speleology () is the scientific study of caves and other karst features, as well as their chemical composition, composition, structure, physical property, physical properties, history, ecology, and the processes by which they form (speleogenesis) and change over time (speleomorphology). The term ''speleology'' is also sometimes applied to the recreational activity of exploration, exploring caves, but this is more properly known as ''caving'', ''potholing'' (British English), or ''spelunking'' (United States and Canadian English). Speleology and caving are often connected, as the physical skills required for ''in situ'' study are the same. Speleology is a cross-disciplinary field that combines the knowledge of chemistry, biology, geology, physics, meteorology, and cartography to develop portraits of caves as complex, evolving systems. History Before modern speleology developed, John Beaumont (geologist), John Beaumont wrote detailed descriptions of some Mendip Hills, Mendip c ...

Cave Diving
Cave-diving is underwater diving in water-filled caves. It may be done as an extreme sport, a way of exploring flooded caves for scientific investigation, or for the underwater search and recovery, search for and recovery of divers or, as in the Tham Luang cave rescue, 2018 Thai cave rescue, other cave users. The equipment used varies depending on the circumstances, and ranges from Free-diving, breath hold to Surface-supplied diving, surface supplied, but almost all cave-diving is done using scuba equipment, often in specialised configurations with engineering redundancy, redundancies such as Sidemount diving, sidemount or backmounted twinset. Recreational cave-diving is generally considered to be a type of technical diving due to the lack of a free surface during large parts of the dive, and often involves planned Decompression (diving), decompression stops. A distinction is made by recreational diver training agencies between cave-diving and cavern-diving, where cavern diving i ...

Riviera Maya
The Riviera Maya () is a tourism and resort district south of Cancun, Mexico. It straddles the coastal Federal Highway 307, along the Caribbean coastline of the state of Quintana Roo, located in the eastern portion of the Yucatán Peninsula. Originally the name applied narrowly, focusing on the area of coastline between the city of Playa del Carmen and Tulum. The designation has since expanded up and down the coast, now including the towns of Puerto Morelos, situated to the north of Playa del Carmen, as well as the town of Felipe Carrillo Puerto, situated to the south of Tulum. This larger region is what is currently being promoted as part of the Riviera Maya tourist corridor. Once the area was originally only called the "Cancun–Tulum corridor", but in 1999 it was renamed as the Riviera Maya, analogous to the Italian and French Riviera, with the instigation of among others, Miguel Ramón Martín Azueta. At the time, he was the municipal president of Solidaridad, Quin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenote
A cenote ( or ; ) is a natural pit, or sinkhole, resulting when a collapse of limestone bedrock exposes groundwater. The term originated on the Yucatán Peninsula of Mexico, where the ancient Maya commonly used cenotes for water supplies, and occasionally for sacrificial offerings. The name derives from a word used by the lowland Yucatec Maya——to refer to any location with accessible groundwater. In Mexico the Yucatán Peninsula alone has an estimated 10,000 cenotes, water-filled sinkholes naturally formed by the collapse of limestone, and located across the peninsula. Some of these cenotes are at risk from the construction of the new tourist Maya Train. Cenotes are common geological forms in low-altitude regions, particularly on islands (such as Cefalonia, Greece), coastlines, and platforms with young post-Paleozoic limestone with little soil development. The term ''cenote'', originally applying only to the features in Yucatán, has since been applied by researchers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belize
Belize is a country on the north-eastern coast of Central America. It is bordered by Mexico to the north, the Caribbean Sea to the east, and Guatemala to the west and south. It also shares a maritime boundary with Honduras to the southeast. Part of the Caribbean region, Belize is a member of the Caribbean Community (CARICOM) and the Commonwealth Caribbean, the historical British West Indies. The Maya civilization spread into the area of Belize between 1500 BCE and 300 CE and flourished until about 1200. European contact began in 1502–04 when Christopher Columbus sailed along the Gulf of Honduras. European exploration was begun by English settlers in 1638. Spanish Empire, Spain and Kingdom of Great Britain, Britain both laid claim to the land until Britain defeated the Spanish in the Battle of St. George's Caye (1798). It became British Honduras, a British colony in 1840, and a Crown colony in 1862. Belize achieved its independence from the United Kingdom on 21 September ...
