Rose Atoll, the easternmost of the islands of the U.S. Territory of American Samoa, lies about 300 km east of Tutuila. The atoll is administered jointly by the Government of American Samoa and the U.S. Fish and Wildlife Service as a National Wildlife Refuge. Rose consists of two small, uninhabited islets about 6 hectares (~15 acres) in total size. The mapping conducted at Rose in 2006 revealed the absence of any shallow surrounding bank and extremely steep slopes that descend to oceanic depths less than half a kilometer offshore.By entering the inner lagoon by one narrow channel on the north side of the atoll, CRED used the R/V AHI to map the detailed lagoon bottom, reaching a maximum depth of about 30 meters.
