Gulfs may be characterized as a portion of the sea or an ocean that extends into the landmass. They greatly vary in size, shape, and also depth and also are developed by the movements of tectonic plates. Also referred to as the Sea that Cortés, the Gulf that California is a long and narrow extension of the east Pacific Ocean and also is geographically positioned along the northwestern coast of Mexico. The Gulf of California separates the mountainous lower California Peninsula/Baja California Peninsula in the west indigenous the claims of Sonora and also Sinaloa ~ above the mainland the Mexico in the east.

Map reflecting the Gulf that California.


The Gulf the California covers an area that 160,000 sq. Km and has a long coastline of around 4,000km. The Gulf is surrounding by the Mexican claims of Sonora, Sinaloa, Baja California, and also Baja California Sur. The Gulf of California is around 1,126km long and has a maximum width ranging in between 48 come 241km. The Gulf is split into 2 portions and also is be separated by a narrowing that is significant by the islands of Tiburón and also Angel de la Guarda. The northern section is relatively shallow, through a mean depth that 180m, if the southern part contains plenty of depressions and also the deepest of this depressions get a preferably depth of over 3,000m. The perilous Salsipuedes container has been developed by the activity of a an effective tidal bore the rushes between the two sections of the Gulf.

Gulf that California, off the coastline of Baja California Sur.  The head that the gulf is conquered by the big Colorado flow Delta through which the Colorado flow drains into the Gulf. The gulf’s east shores are surrounded by highlands that are damaged by several major Mexican rivers that drainpipe into the Gulf that California consisting of the Rio Sonora River, the Sinaloa River, the mei River, the Fuerte River, and also the Yaqui River. The long coast of the gulf is extremely irregular and forms numerous tiny bays. Over there are also many ‘negative estuaries’, and also three types of shores including the sandy beach, the rocky shore, and the tidal flat in the Gulf the California. La Paz top top the Baja California Peninsula and Guaymas on the mexico mainland room the two major ports the are located along the shores of the Gulf.


Aerial check out of the soil End and the Arch that Cabo san Lucas, Baja California Sur, Mexico.  Geological studies have identified that the Gulf the California to be created approximately 5.3 million years back due to the motion of tectonic plates the separated the Baja California Peninsula from the phibìc American Plate. The eastern Pacific climb that runs southern from the Gulf the California separates the Pacific Plate from the north American Plate, the Nazca Plate, the Rivera Plate, the Cocos Plate, and the Antarctic Plate. The east Pacific rise extends approximately the facility of the Gulf along the seabed. This northernmost expansion of the east Pacific increase is described as the Gulf of California Rift Zone, i m sorry extends for an ext than 1,300km indigenous the mouth of the Gulf of California to the southern finish of the mountain Andreas Fault. Motions along the mountain Andreas error are led to by the dispersing beneath the eastern Pacific Rise. The northward movement along the fault around 3 to 4 million years ago, resulted in the development of the Baja Peninsula and the succeeding detachment of the Baja California Peninsula from the mexico mainland. The Gulf the California then began to open as a collection of offsets in addition to the mountain Andreas error system. The tectonic tasks along the faults proceed till day that is causing the spreading apart that the plates and the cultivation of the California gulf between the peninsula and the mexican mainland.


Aerial watch from Espiritu Santo Island, Baja California Sur, Mexico.  over there are around 37 significant islands in the Gulf of California the is greatly located top top its west side. The is thought that this islands were developed due to volcano eruptions and several of these islands are home to volcanoes. Some of the major islands include the Isla Ángel de la Guarda, Isla Tiburón, Islas Marías, Isla Partida, Islas mountain Francisco, Isla Coronados, etc.

It is approximated that there are much more than 900 islets and also islands in the Gulf of California that cover a complete area of around 420 hectares. In 1978, every these islets and islands to be designated as “Area Reserve and also Migratory Bird Refuge and also Wildlife”. In June 2000, all the archipelago were claimed “flora and fauna security area”. All the islands in the gulf eventually became a part of the MAB regimen under UNESCO. In 2005, the Islands and the Protected locations of the Gulf of California were designated together a UNESCO civilization Heritage Site.


Due come the existence of an uninterrupted chain of hills on the Baja California Peninsula, the Gulf the California experience a ‘continental’ climate quite than one ‘oceanic’ climate. The temperature that the surface water varieties from 24°C during summers to about 16°C during winters. However, the temperatures differ greatly and also the water is comparatively much warmer top top the shores than in the open up ocean. The northern component of the gulf regularly experiences cold winters wherein the water temperature drop listed below 8°C. The median annual range of the surface water salinity vary between 3.5 and also 3.58 with the salinity the the north gulf waters being comparatively higher than the central and southern components of the gulf.

Coral Reefs in the Gulf the California.  The Gulf the California is thought about one that the most diverse seas top top the planet. The waters that the Gulf are residence to an ext than 5,000 species of micro-invertebrates. The Gulf the California likewise supports a high diversity of naval life including an ext than 900 types of fish in addition to coral reefs, dolphins, and marine turtles. The gulf supports plenty of endemic marine animals such together the vaquita. Several migratory types like the California gray whale, humpback whale, manta ray, killer whale, Humboldt squid, the blue whale, and the leatherback sea turtle. Resident populations of sperm whales and also fin whales are likewise found in the gulf waters. The marine waters likewise support several of Mexico’s most crucial fisheries and also the entire region serves together a far-ranging place because that the commercial fishing industry. The archipelago of the gulf provide vital breeding habitats for many seabirds.

Brief history

In 1532, the Spanish conquistador Hernán Cortés got to the gulf while trying out the Pacific coast of Mexico. Cortés and his team yet returned come Spain with a handful of pearls that they had built up from the gulf. In 1535, Cortés led a second expedition throughout the gulf to the Baja Peninsula, which to be then assumed to be an island. In 1539, the Spanish traveler – Francisco de Ulloa, who was trying out the west shore of Mexico, confirmed that Baja California to be a peninsula and not an island. He at first named the gulf “Mar Bermejo” or “Vermilion Sea” introduce to the red shade of the plankton blooms. The Gulf was likewise named as the “Sea the Cortés” through Francisco de Ulloa in the respect of the Spanish conquistador Hernán Cortés. The US yielded the Gulf the California, the Baja Peninsula, and also a thin piece of soil that linked the peninsula v the mexico mainland to Mexico via the contract of Guadalupe.
