Coral reefs around the world face numerous threats, both natural and
anthropogenic, including pollution, natural disasters, invasive species, habitat destruction,
and destructive methods of fishing. Given enough time, coral can recover from natural
disasters, but anthropogenic threats decrease corals’ ability to recover from things such as
hurricanes. It is difficult to protect coral reefs when they are not fully mapped or
understood and without public support for their protection. This project is an attempt to
both understand more about two small coral reefs around the island of Tutuila, American
Samoa and to facilitate public outreach and education about coral reefs in American
Samoa. New benthic zone and structure classifications have been produced for Fagaitua
Bay and for National Park of American Samoa, which extend earlier satellite-based
classifications into much deeper water. Although it is not possible, at this time, to tie
benthic classifications to species or community types, it is hoped that further ground-truth
data may establish some connection between the two.
Government officials and resource managers increasingly use GIS to determine
the locations of critical habitats in need of protection. There is growing concern,
however, that the general public is excluded from the decision-making process due to the
lack of publicly-accessible data. The American Samoa Benthic Terrain Viewer (ASBTV)
is a web-based geographic information system (GIS) that allows users to display data and
conduct simple GIS analyses without the need to purchase stand-alone GIS software. All
of the benthic classifications produced for American Samoa as part of this and other
projects are available on the ASBTV. ASBTV also includes the world’s first web-based
GIS in the Samoan language. Educational modules developed for American Samoa
Community College are also part of the effort to make the public more aware of current
research on the coral reefs in American Samoa. It is also hoped that they will aid in GIS
capacity building efforts by providing students with the opportunity to learn GIS using
local data. The educational modules include a capstone final project where students must
tie in the technical skills they have learned in the class to a real-world problem: a
hypothetical marine protected area proposal. None of these efforts towards public
education, GIS capacity building, and reef protection can stand alone. Without
traditional outreach, Internet outreach is often unsuccessful. Without public support, reef
protection and GIS education will not often be successful.
