Gulf of Mexico in the context of "Delek Group"

Mexico, officially the United Mexican States, is a country in North America. It is the northernmost country in Latin America and borders the United States to the north, and Guatemala and Belize to the southeast; while having maritime boundaries with the Pacific Ocean to the west, the Caribbean Sea to the southeast, and the Gulf of Mexico to the east. Mexico covers 1,972,550 km (761,610 sq mi), and is the thirteenth-largest country in the world by land area. With a population exceeding 130 million, Mexico is the tenth-most populous country in the world and is home to the largest number of native Spanish speakers. Mexico City is the capital and largest city, which ranks among the most populous metropolitan areas in the world.

Human presence in Mexico dates back to at least 8,000 BC. Mesoamerica, considered a cradle of civilization, was home to numerous advanced societies, including the Olmecs, Maya, Zapotecs, Teotihuacan civilization, and Purépecha. Spanish colonization began in 1521 with an alliance that defeated the Aztec Empire, establishing the colony of New Spain with its capital at Tenochtitlan, now Mexico City. New Spain became a major center of the transoceanic economy during the Age of Discovery, fueled by silver mining and its position as a hub between Europe and Asia. This gave rise to one of the largest multiracial populations in the world. The Peninsular War led to the 1810–1821 Mexican War of Independence, which ended Peninsular rule and led to the creation of the First Mexican Empire, which quickly collapsed into the short-lived First Mexican Republic. In 1848, Mexico lost nearly half its territory to the American invasion. Liberal reforms set in the Constitution of 1857 led to civil war and French intervention, culminating in the establishment of the Second Mexican Empire under Emperor Maximilian I of Austria, who was overthrown by Republican forces led by Benito Juárez. The late 19th century saw the long dictatorship of Porfirio Díaz, whose modernization policies came at the cost of severe social unrest. The 1910–1920 Mexican Revolution led to the overthrow of Díaz and the adoption of the 1917 Constitution. Mexico experienced rapid industrialization and economic growth in the 1940s–1970s, amidst electoral fraud, the Tlatelolco massacre, and economic crises. The late 20th century saw a shift towards neoliberalism, marked by the signing of the North American Free Trade Agreement (NAFTA) in 1994, amidst unrest in Chiapas.

A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern.

Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water catchment, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of the drainage divide line.

The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude (North Carolina) and moves toward Northwest Europe as the North Atlantic Current. The process of western intensification causes the Gulf Stream to be a northward-accelerating current off the east coast of North America. Around 40°0′N 30°0′W / 40.000°N 30.000°W / 40.000; -30.000, it splits in two, with the northern stream, the North Atlantic Drift, crossing to Northern Europe and the southern stream, the Canary Current, recirculating off West Africa.

The Gulf Stream influences the climate of the coastal areas of the East Coast of the United States from Florida to southeast Virginia (near 36°N latitude), and to a greater degree, the climate of Northwest Europe. A consensus exists that the climate of Northwest Europe is warmer than other areas of similar latitude at least partially because of the strong North Atlantic Current. It is part of the North Atlantic Gyre. Its presence has led to the development of strong cyclones of all types, both within the atmosphere and within the ocean.

Veracruz, officially the Free and Sovereign State of Veracruz de Ignacio de la Llave, is one of the 31 states which, along with Mexico City, comprise the 32 Federal Entities of Mexico. Located in eastern Mexico, Veracruz is bordered by seven states: Tamaulipas, San Luis Potosí, Hidalgo, Puebla, Oaxaca, Chiapas, and Tabasco. Veracruz is divided into 212 municipalities, and its capital city is Xalapa-Enríquez.

Veracruz has a significant share of the coastline of the Gulf of Mexico on the east of the state. The state is noted for its mixed ethnic and indigenous populations, and its cuisine reflects the many cultural influences that have come through the state because of the importance of the port of Veracruz. In addition to the capital city, the state's largest cities include Veracruz, Coatzacoalcos, Córdoba, Minatitlán, Poza Rica, Boca Del Río and Orizaba.

Tabasco, officially the Free and Sovereign State of Tabasco, is one of the 32 Federal Entities of Mexico. It is divided into 17 municipalities and its capital city is Villahermosa.

It is located in southeast Mexico and is bordered by the states of Campeche to the northeast, Veracruz to the west, and Chiapas to the south and the Petén department of Guatemala to the southeast. It has a coastline to the north with the Gulf of Mexico. Most of the state is covered in rainforest as, unlike most other areas of Mexico, it has plentiful rainfall year-round. The state is also home to La Venta, the major site of the Olmec civilization, considered to be the origin of later Mesoamerican cultures. It produces significant quantities of petroleum and natural gas.

The Caribbean Sea is a sea of the North Atlantic Ocean in the tropics of the Western Hemisphere, located south of the Gulf of Mexico and southwest of the Sargasso Sea. It is bounded by the Greater Antilles to the north from Cuba to Puerto Rico, the Lesser Antilles to the east from the Virgin Islands to Trinidad and Tobago, South America to the south from the Venezuelan coastline to the Colombian coastline, and Central America and the Yucatán Peninsula to the west from Panama to Mexico. The geopolitical region around the Caribbean Sea, including the numerous islands of the West Indies and adjacent coastal areas in the mainland of the Americas, is known as the Caribbean.

The Caribbean Sea is one of the largest seas on Earth and has an area of about 2,754,000 km (1,063,000 sq mi). The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at 7,686 m (25,217 ft) below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, the Gulf of Venezuela, the Gulf of Darién, Golfo de los Mosquitos, the Gulf of Paria and the Gulf of Honduras.

The Mississippi River System, also referred to as the Western Rivers, is a mostly riverine network of the United States which includes the Mississippi River and connecting waterways. The Mississippi River is the largest drainage basin in the United States. In the United States, the Mississippi drains about 41% of the country's rivers.

From the perspective of natural geography and hydrology, the system consists of the Mississippi River itself and its numerous natural tributaries and distributaries. The major tributaries are the Arkansas, Illinois, Missouri, Ohio and Red rivers. Given their flow volumes, major Ohio River tributaries like the Allegheny, Tennessee, and Wabash rivers are considered important tributaries to the Mississippi system. Before the Mississippi River reaches the Gulf of Mexico, it runs into its distributary, the Atchafalaya River.

The Mississippi River is the primary river of the largest drainage basin in the United States. It is the second-longest river in the United States, behind only the Missouri. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for 2,340 mi (3,770 km) to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. The main stem is entirely within the United States; the total drainage basin is 1,151,000 sq mi (2,980,000 km), of which only about one percent is in Canada. The Mississippi ranks as the world's tenth-largest river by discharge flow, and the largest in North America.

Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Many were hunter-gatherers, but some, such as the Mound Builders, formed prolific agricultural and urban civilizations, and some practiced aquaculture. The arrival of Europeans in the 16th century changed the native way of life as first explorers, then settlers, ventured into the basin in increasing numbers. The river served sometimes as a barrier, forming borders for New Spain, New France, and the early United States, and throughout as a vital transportation artery and communications link. In the 19th century, during the height of the ideology of manifest destiny, the Mississippi and several tributaries, most notably its largest, the Ohio and Missouri, formed pathways for the western expansion of the United States. The river also became the subject of American literature, particularly in the writings of Mark Twain.

Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes. Hypoxia occurs when dissolved oxygen (DO) concentration falls to or below 2 mg of O₂/liter. When a body of water experiences hypoxic conditions, aquatic flora and fauna begin to change behavior in order to reach sections of water with higher oxygen levels. Once DO declines below 0.5 mg O₂/liter in a body of water, mass mortality occurs. With such a low concentration of DO, these bodies of water fail to support the aquatic life living there. Historically, many of these sites were naturally occurring. However, in the 1970s, oceanographers began noting increased instances and expanses of dead zones. These occur near inhabited coastlines, where aquatic life is most concentrated.

Coastal regions, such as the Baltic Sea, the northern Gulf of Mexico, and the Chesapeake Bay, as well as large enclosed water bodies like Lake Erie, have been affected by deoxygenation due to eutrophication. Excess nutrients are put into these systems by rivers, ultimately from urban and agricultural runoff and exacerbated by deforestation. These nutrients lead to high productivity that produces organic material that sinks to the bottom and is respired. The respiration of that organic material uses up the oxygen and causes hypoxia or anoxia.
