Gulf of California

About Gulf of California:

• The Gulf of California, also called the Sea of Cortez is a large inlet of the eastern Pacific Ocean along the northwestern coast of Mexico. 
• It separates the mountainous Lower California Peninsula/Baja California Peninsula in the west from the states of Sonora and Sinaloa on the mainland of Mexico in the east.
• Geography:
  • It covers an area of 160,000 sq. km and has a long coastline of approximately 4,000km. 
  • It is about 1,126km long and has a maximum width ranging between 48 to 241km. 
  • The Gulf is divided into two portions and is separated by a narrowing that is marked by the islands of Tiburón and Angel de la Guarda.
  • The northern portion is relatively shallow, with a mean depth of 180m, while the southern portion contains many depressions and the deepest of these depressions reaches a maximum depth of over 3,000m. 
  • The head of the gulf is dominated by the large Colorado River Delta through which the Colorado River drains into the Gulf.
  • The long coastline of the gulf is extremely irregular and forms numerous small bays. 
• Geology: The Gulf of California was created around 5.3 million years ago due to the movement of tectonic plates that separated the Baja California Peninsula from the North American Plate. 
• Islands:
  • There are about 37 major islands in the Gulf of California that is mostly located on its western side.
  • It is believed that these islands were created due to volcanic 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 San Francisco, Isla Coronados, etc.
• Climate: Due to the presence of an uninterrupted chain of mountains on the Baja California Peninsula, the Gulf of California experiences a ‘continental’ climate rather than an ‘oceanic’ climate.
