The Darwinian progressive subsidence model for the evolution of fringing reefs, barrier reefs and atolls has been generally accepted following the indisputable proof of subsidence provided by drilling results in the Pacific. Nonetheless, there are data that do not fit the expectations of the model, ...
However, in addition to corals there are enormous quantities of algae, some calcareous, which help to build the reefs. The size of reefs is variable. Some atolls are very large—Kwajelein in the Marshall Islands of the South Pacific is 120 kilometers long and as much as 24 kilometers ...
On the Formation of Barrier Reefs and of the Different Types of AtollsThe results here presented are based upon observations carried on during the past 25 years in Florida, the Bermudas, Bahamas, Cuba, Jamaica, and the West Indies in the Atlantic. They include in the Pacific the Galapagos, ...
Barrier reefs and atolls of French Polynesia are surrounded by warm and clear oligotrophic water of the South Pacific gyre. Atolls forming the Tuamotu Archipelago show great geomorphologic and hydrologic diversity. Reef-lagoon systems of other archipelagoes (Society Islands, Austral Islands) are ...
However, while the BBRRS’s size and diversity helps make it resilient to environmental impacts such as hurricanes, we’re now better understanding the toll that climate change and increased human activity and exploitation are taking on both the Belize and Australian Great Barrier Reefs. These chal...

than 700 patch reefs inside its 100 square mile crystalline lagoon. Of the three atolls Glover’s Reef sees the least amount of human contact and is largely unexplored. Come see for yourself why this atoll was designated a National Marine Reserve and, in 1997, a World Heritage Site by ...
19. lowstands was responsible for the raised rims and other morphological features of atolls and barrier reefs11,12 (Supplementary Fig. S1 online). Evidence supporting a link between reef types, however, had already started to emerge from last-Interglacial reef-terraces on the Huon Peninsula, ...
Two smaller barrier reefs and a few small atolls with shallower lagoons are found near by. The lees depth of these lagoons, like that of the narrower parts of the Tagula lagoon, is undoubtedly due to the greater efficiency of aggradation by inwashed reef detritus -in lagoons of small area...
