| Bassas da India is an emerging, circular madreporic atoll, with an area lower than 1 sq. km. |
| Diving is generally within the atoll lagoons for the inexperienced, and outside the atolls on reef walls for the advanced. |
| My plan involves me videotaping my own isolation on the atoll, but Explorer also wants to send a second cameraperson for a portion of my trip. |
| Each atoll is the topmost point of a submarine pillar of limestone extending several thousand feet from an extinct volcano. |
| From the air the tiny islets of Funafuti atoll appear as a broken pearl necklace scattered on the blue throat of the tropical sea. |
| The large seaplanes landed in the quiet atoll waters and pulled up to a float offshore. |
