Red Triangle (Pacific Ocean)

The Red Triangle is the colloquial name of a roughly triangle-shaped region off the coast of northern California, extending from Bodega Bay, north of San Francisco, out slightly beyond the Farallon Islands, and down to the Big Sur region, south of Monterey.

[4] The movement of sharks and other large marine animals in this region were studied starting in 1999 under the Tagging of Pacific Predators (TOPP) program, an international collaboration.

[5] The population of northeastern Pacific white sharks tend to congregate along the north/central California coast each fall, then leave the area in December for the deep ocean approximately halfway between California and Hawaii.

[5] Female whites tend to visit the Gulf of the Farallones every two years, which researchers believe to be based on the shark reproductive cycle.

[4] Adult Great White Sharks are no longer present in the Red Triangle during the month of May, and start to return in August.
