The Maldives are among the largest reef areas. The archipelago consists of 21 atolls (14 larger and 7 smaller ones) and 4 reef-fringed islands (small atolls with completely sediment-filled lagoons, i.e., filled buckets) that cover a total area of 21,370 km2. In order to get a better understanding of the variety of reef forms in this major carbonate platform location, reef areas, reef types, and other geomorphological elements such as channels through marginal reefs, lagoons, lagoon patch reefs… Expand

Reef growth and limestone erosion
Because the shapes and forms of many coral reefs resemble karst (erosion landforms created by dissolution of limestone), it is widely believed that those reefs have grown on karst foundations, andExpand
Last interglacial reef facies and late Quaternary subsidence in the Maldives, Indian Ocean
Abstract To date, there is hardly any knowledge of facies and age of Pleistocene reef limestone in the Maldives. Likewise, there are no robust estimates of Quaternary subsidence in this majorExpand
Holocene sedimentary evolution of a mid-ocean atoll lagoon, Maldives, Indian Ocean
Abstract Based on detailed analyses of cores covering the lagoon of Rasdhoo Atoll, Maldives, six carbonate facies, one soil, and one peat facies have been identified. The abundance of carbonate andExpand
Oceanographic habitat and the coral microbiomes of urban-impacted reefs
TLDR
Overall, it is found that physical oceanographic variability correlates with the structure of these coral microbiomes in ways that could be significant to coral health. Expand

Abstract In recent years, considerable research has been undertaken in order to gain a better quantitative understanding of morphometric patterns within modern carbonate depositional systems. TheExpand
Changes in diversity and assemblages of foraminifera through the Holocene in an atoll from the Maldives, Indian Ocean

Submerged reef terraces in the Maldivian Archipelago (Indian Ocean)
Abstract Sea-level changes have shaped the world's carbonate platform margins and continental shelves, leaving typical geomorphic imprints, such as drowned reef terraces. In this paper, we presentExpand
