Title:
CRED Cumulative Map of Percent Scleractinian Coral Cover at Ofu & Olosega
Abstract:
This map displays optical validation observation locations and percent coverage of scleractinian coral overlaid on bathymetry.
Supplemental_Information:
Ofu and Olosega Islands are part of the Manu'a Island group in American Samoa, situated approximately 100 km northeast of Tutuila and 20km west of Ta'u. Centered at 14.17S, 169.65W, the twin islands have very little human settlement. Ofu and Olosega are steep, volcanic high islands that lie only 75 m apart and are connected by a bridge and road built across the shallow reef flat. Shallow multibeam mapping was conducted in 2004 and revealed ~60 km2 of previously uncharted bank top (<300 m) that extends 0.2 to 2 km from shore and then drops abruptly to oceanic depths. An underwater portion of the National Park of American Samoa, which has exceptionally prolific coral growth, is located on the south shore of Ofu Island.
