Ross Atoll Ross Atoll Ross Atoll is a small atoll in the Admiralty Chart with an almost round lagoon. It is located at about five miles from the Northeast point of Ari Atoll. The northern and western sides form one continuous barrier reef, and the eastern side is another barrier reef. The four mile wide lagoon has soundings from 15 to 20 fathoms (27 to 37 m) and abounds in detached coral patches. This natural atoll was named Ross Atoll by Captain Robert Moresby during his survey of the Maldive Islands. It was named after Captain Daniel Ross of the Bombay Navy,
Laamu Atoll Laamu Atoll Laamu Atoll (also known as Haddhunmathi Atoll) is an administrative division of the Maldives. It corresponds to the natural atoll of the same name. The administrative capital is located in Fonadhoo Island. Traditionally, Maldivians call this atoll simply 'Haddhunmathi', without adding the word 'Atholhu' at the end. It is mostly rimmed by barrier reefs, the broadest of which are topped by islands. There are many islands along its eastern and southern boundaries. This atoll is quite regular excepting for the projection of the reef at its NE corner (Isdhū Muli). It closely resembles Kolhumadulhu, its neighbour further north.
