American Samoa Survey

Revealing the world's largest and oldest coral

The National Marine Sanctuary of American Samoa is located in the cradle of Polynesia’s oldest culture and is thought to support the greatest diversity of marine life in the National Marine Sanctuary System. It houses extensive coral reefs, including some of the oldest and largest Porites coral heads in the world which are found in "The Valley of the Giants" (Ta'u, Manu'a).

A small survey team was invited to visit these remote waters in collaboration with the National Oceanic and Atmospheric Administration (NOAA) and NOAA Office of National Marine Sanctuaries.
