They are the same thing. Mexican maps prefer sea of Cortez;English maps Gulf of California.

From Wikipedia:

The Gulf of California (also known as the Sea of Cortez or Sea of Cortés or Vermilion Sea; locally known in the Spanish language as Mar de Cortés or Mar Bermejo or Golfo de California) is a body of water that separates the Baja California Peninsula from the Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately 2,500 mi (4,000 km). Rivers which flow into the Gulf of California include the Colorado, Fuerte, Mayo, Sinaloa, Sonora, and the Yaqui. The gulf's surface area is about 62,000 sq mi (160,000 km2). The name "Gulf of California" predominates on most maps in English today. The name "Sea of Cortés" is the one preferred by most local residents.
