Coral reef habitats are changing due to both natural and anthropogenic influences operating at different scales. To better understand and differentiate between these processes, it is important to reconstruct natural variability in reef communities. Here, we examine late Holocene sediments (0–4 kyrs BP) along three vibracores from marginal and central locations, and adjacent to a patch reef, in the lagoon of Rasdhoo Atoll, Maldives. Sediment analysis included quantification of corals, echinoids, and sponges, as well as changes in texture. In addition, growth forms and degree of encrustation of coral fragments were documented. The aim of this study is to identify fluctuations in the proportion of organism remains and sediment composition and possible patterns over time in response to environmental changes. The sediment compositions in the three cores are substantially different. Fragments of reef corals (including Acropora spp., Seriatopora hystrix) were found preferentially in two cores adjacent to reef structures and channels through the atoll rim, suggesting sediment redeposition due to enhanced water circulation compared to the deeper lagoon location. Fragments of echinoids belonging to Echinometra sp., Diadema sp. and Cidaridae, mainly decreased in abundance over time. Different trends in organism proportion in the three cores can be attributed to local changes in ecological interactions among organisms, lagoonal circulation influenced by patch-reef growth and sand-spit development, and regional sedimentological events including tsunamis. Global changes in temperature, El-Niño frequency, and sea level fluctuations did not leave clear imprints in the lagoonal record. This study highlights that organism remains from atoll lagoons have great potential as archives of local to regional ecological and environmental change, as they store information on faunal composition, long-term geomorphological change, and short-term events and should therefore receive more attention in future investigations.

The Hawaiian–Emperor Seamount Chain, a major topographic feature of the Pacific Ocean floor, is composed of seamounts capped with fossil coral reef deposits that originally formed close to sea level but are now covered by hundreds of meters of water owing to prolonged subsidence. These fossil reef deposits are important archives of paleoenvironmental change and yield information on the subsidence history of the seamounts. We studied the Sr isotope compositions of Oligocene–Miocene coral reef limestone from Koko Guyot in the southern Emperor Seamount Chain to assess the dynamics of the subsidence. The ages of the studied samples containing coral fragments established by Sr isotope stratigraphy vary from 26.3 to 20.1 Ma. In contrast, the youngest samples (15.3 Ma), which were deposited in water depths of >120 m, are barren of corals and are composed exclusively of bryozoans and coralline algae. The subsidence rate of the Koko Guyot volcanic structure was not constant over time. Integration of our new data with the results of previous studies reveals that the subsidence rate was 0.046 ± 0.005 mm/yr during the first 25–30 Myr (from 49–44 to 20 Ma). During this period, Koko Guyot was in a bathymetric interval favorable for coral reef development, and its subsidence was compensated by rapid vertical growth of the reef. Subsequently, the subsidence rate decreased to an average value of 0.019 ± 0.003 mm/yr from 20 to 15 Ma. The decrease in the rate of bottom subsidence coincided with unfavorable environmental conditions for coral reef development, leading to the disappearance of corals. The average subsidence rate has been 0.015 ± 0.002 mm/yr since 15 Ma, comparable to the present-day subsidence rate. We also analyzed the stable Sr isotope ratios (δ88/86Sr) of warm-water coral samples formed at 25–20 Ma (0.32‰ ± 0.1‰), as well as carbonate of large benthic foraminifera, coralline algae, and other non-coral species for the period 20–15 Ma (0.10‰ ± 0.09‰). We suggest that the large difference in carbonate δ88/86Sr between 25–20 and 20–15 Ma corresponds to a difference in the fractionation factor caused by environmental and benthic community change.
