NOTES: Not all atolls are included here (none from Indonesian waters, for example). Atolls that have lost their lagoons (such as Nukutuvake, Tuamotu Archipelago) are not included. Atoll-like reefs (sunken atolls) are included. Atolls that currently have an entry on the site are linked to that particular entry; those that are not currently on the site have no link (such as those of the Caroline Islands and Solomon Islands, for example).
