| The surface of the gulf is about 160,000xc2xa0km2 (62,000xc2xa0sqxc2xa0mi). | WIKI |
| The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. | WIKI |
| The International Hydrographic Organization defines the southern limit of the gulf as: "A line joining Piaxtla Point (latitude 23xc2xb038'N) on the west coast of the mainland of Mexico, and the southern extreme of Lower California". | WIKI |
| The gulf is 1,126xc2xa0km (700xc2xa0mi) long and 48xe2x80x93241xc2xa0km (30xe2x80x93150xc2xa0mi) wide, with an area of 177,000xc2xa0km2 (68,000xc2xa0sqxc2xa0mi), a mean depth of 818.08xc2xa0m (2,684.0xc2xa0ft), and a volume of 145,000xc2xa0km3 (35,000xc2xa0cuxc2xa0mi). | WIKI |

| Satellite picture of the gulf | WIKI |
| Geologic evidence is widely interpreted by geologists as indicating the gulf came into being around 5.3 million years ago as tectonic forces rifted the Baja California Peninsula off the North American Plate. | WIKI |
| [7] As part of this process, the East Pacific Rise propagated up the middle of the Gulf along the seabed. | WIKI |
| The Gulf would extend as far as Indio, California, except for the tremendous delta created by the Colorado River. | WIKI |
| [8] Furthermore, hydrothermal vents due to extension tectonic regime, related to the opening of the gulf, are found in the Bahxc3xada de Concepcixc3xb3n, Baja California Sur. | WIKI |
| The gulf contains 37 major islands xe2x80x93 the two largest being Isla xc3x81ngel de la Guarda and Isla Tiburxc3xb3n. | WIKI |
| Most of the islands are found on the west side of the gulf. | WIKI |
| In fact, many of the islands of the gulf are the result of volcanic eruptions that occurred during the early history of Baja California. | WIKI |
| The gulf has more than 900 islets and islands which together total about 420 hectares. | WIKI |
| In addition to this effort by the Mexican government, for its importance and recognition worldwide, all islands in the gulf are also part of the international program "Man and Biosphere" (MAB) and are part of the World Reserve Network UNESCO Biosphere as Special Biosphere Reserve. | WIKI |
| The three general types of shores found in the gulf include rocky shore, sandy beach, and tidal flat. | WIKI |
| Some of the rich biodiversity and high endemism that characterize the gulf and make it such a hotspot for fishing can be attributed to seemingly insignificant factors, such as the types of rocks that make up a shore. | WIKI |
| The northern gulf experiences tidal ranges of up to 5xc2xa0m (16xc2xa0ft). | WIKI |
| Mixed semidiurnal tides are the norm throughout most of the Gulf. | WIKI |
| The temperatures, poikilothermal, of these negative estuaries also are higher than the general temperature of the gulf. | WIKI |
| However, because of human settlement around the gulf and water diversion for municipal and agricultural use in an area of comparatively low rainfall, there are no longer many rivers that freely empty into the gulf. | WIKI |
| The remaining gulf inlets still are important to several species of fishes, crustaceans, and shellfish that are commercially harvested. | WIKI |
| Even though the shores of the gulf are generally sheltered from the continuous wave shock that is experienced by most other North American shores, storms known as a "chubasco" can cause significant damage to shorelines, despite their brevity. | WIKI |
| [3] The temperature of the water in the gulf generally experiences lows of 16xc2xa0xc2xb0C (61xc2xa0xc2xb0F) in winter and highs of 24xc2xa0xc2xb0C (75xc2xa0xc2xb0F) in summer. | WIKI |
| But temperatures can vary greatly in the gulf, and the water is almost always warmer by the coast than the open ocean. | WIKI |
| Occasionally, the northern gulf will go through significantly cold winters. | WIKI |
| The water in the northern gulf can sometimes drop below 8xc2xa0xc2xb0C (46xc2xa0xc2xb0F), which can lead to a large die-off of marine organisms. | WIKI |
| However, the data vary wildly according to the species being studied, and the gulf's ability to recuperate after years of overfishing remains uncertain. | WIKI |
| Moreover, changes in terrestrial ecology, such as the vast reduction in flow from the Colorado River into the gulf, have negatively affected fisheries, particularly in the northern region. | WIKI |
| The gulf sustains a large number of marine mammals, many of which are rare and endangered. | WIKI |
| For decades, the gulf has been a primary source of two of Mexico's leading marine resources, sardines and anchovies. | WIKI |
| Water pollution is a problem in the gulf, but the more immediate concerns are overfishing and bottom trawling, which destroys eelgrass beds and shellfish. | WIKI |
| Efforts by the Mexican government to create conservation zones and nature reserves have been hampered by lack of enforcement resources as well as a lack of a political consensus on this issue of conservation of the Gulf. | WIKI |
| Conservation of the gulf's fisheries and coastlines is also complicated by a long history of overcapitalization in the sector, and the direct, often negative, impacts that conservation measures have on the livelihoods of Mexico's coastal inhabitants. | WIKI |
| At present, the Mexican government and business interests have promoted a macro-level, tourist development vision for the gulf, the impacts of which on local ecology and society are uncertain. | WIKI |
| In 2019, the gulf was added to the List of World Heritage in Danger because of concerns of the imminent extinction of the vaquita, an endemic porpoise in the area. | WIKI |
| The well-developed shrimp and sardine fleets of Mazatlxc3xa1n, on the Mexican mainland's Pacific coast, heavily exploit the commercial fisheries of the southern gulf. | WIKI |
| Many marine organisms can only survive within a particular salinity range, which makes salinity a notable factor in determining the types of potentially commercial organisms found in the gulf. | WIKI |
| [1] Furthermore, the salinity of the water of the northern gulf is generally higher than the central and southern faunal regions due to the increased amount of evaporation that occurs in that region. | WIKI |
| As a serial property, Islands and Protected Areas of the Gulf of California includes representative components of all major oceanographic zones of the biogeographically diverse Gulf, thereby capturing a broad spectrum of landscapes and conservation values. | UNESCO |
| Speciation both on land in the many islands and in the Gulf has resulted in a notable diversity of life forms with a high degree of endemism. | UNESCO |
| The productivity of the Gulf also leads an extraordinary natural abundance of many marine species. | UNESCO |
| The five species of dolphin include the critically endangered Gulf Porpoise or "Vaquita". | UNESCO |
| Eleven species of whale visit the northern Gulf, such as the endangered Blue Whale and Fin Whale and the vulnerable Sperm Whale. | UNESCO |
| Management responses are needed to ensure that harvesting levels are adapted to the productivity in the entire Gulf. | UNESCO |
