In 1972, in response to a growing awareness of the value of our coastal waters, Congress passed the Marine Protection, Research, and Sanctuaries Act. The act authorized the designation of National Marine Sanctuaries to protect significant waters and secure habitat for aquatic species, shelter historically significant shipwrecks and other cultural resources, and serve as valuable spots for research, fishing, wildlife viewing, boating, and tourism.

Marine Sanctuaries are special areas of the oceans, coastal waters, and Great Lakes. Here are some facts about the sanctuaries:

  • Thirteen Sanctuaries exist today, ranging in size from 1 to more than 5,000 square miles
  • The Gulf of the Farallones National Marine Sanctuary encompasses 948 square nautical miles of water off the California coastline west of San Francisco and includes offshore marine regions of the Gulf of the Farallones and the nearshore waters of Bodega Bay, Tomales Bay, Estero de San Antonio, Estero Americano, and Bolinas Lagoon
  • Gulf of the Farallones Sanctuary was designated in 1981
  • The Sanctuary is part of the United Nations' Golden Gate Biosphere Reserve
  • Ocean wilderness juxtaposed to the 8 million residents of the San Francisco Bay Metropolitan Area
  • Nursery for harbor seals, elephant seals, harbor porpoises, Pacific white-sided dolphins, rockfish, and seabirds including the Tufted Puffin. Twenty percent of California's harbor seals breed in the Gulf of the Farallones Sanctuary
  • Largest breeding concentration of seabirds in the contiguous United States. More than 400,000 seabirds breed in the Sanctuary
  • Thirty-six marine mammal species have been documented in the Gulf of the Farallones
  • Destination feeding grounds for endangered blue whales and humpback whales
  • One of the largest remaining blue whale populations on Earth
  • Major migration route of gray whales and small resident population
  • Stopover resting and feeding area for migrating birds
  • One of the last populations of threatened Steller sea lions
  • One of the largest concentration of white sharks in the world
  • Home to 27 endangered or threatened species
  • Fifty-two species of rockfish are found in the Gulf of the Farallones Sanctuary

Why care about the ocean?

  • The ocean covers more than 70% of the earth's surface
  • Home to more than 90% of all living things
  • More than 50% of the world's protein comes from the ocean
  • Generates four times as much oxygen as green plants on land
  • Regulates the global climate
  • Contributes trillions of dollars to the global economy

Why support the Gulf of the Farallones National Marine Sanctuary and the Farallones Marine Sanctuary Association?

  • Working to protect the marine environment
  • Responds to oil spills and other environmental emergencies
  • Monitors the shoreline for natural and human caused disturbances
  • Monitors endangered species
  • Develops and/or supports collaborative programs to protect endangered species
  • Develops programs to reduce disturbance to marine life
  • Develops and implements programs to protect and/or restore marine habitats
  • Educates adults and children about the marine environment
  • Involves citizens in marine research and conservation

Some of the Gulf of the Farallones National Marine Sanctuary success stories:

  • Stopped oil drilling along the San Mateo, San Francisco, Marin and Southern Sonoma coasts.
  • Prohibits the discharge of materials into the Sanctuary
  • After more than 170 years northern fur seals are breeding on the Farallon Islands
  • Restoring the Common Murre population to breeding areas affected by oil spills
  • Reduced disturbance to harbor seals which has lead to the increased survival rate of pups
