Rapid Smothering of Coral Reef Organisms by Muddy Marine Snow

Estuarine, Coastal and Shelf Science, 2000
Abstract Estuarine mud, when resuspended in nutrient-rich near-shore water, aggregates to marine snow, and within minutes to hours can exert detrimental or even lethal effects on small coral reef organisms. In a pilot study, estuarine mud was suspended in near-shore and off-shore waters of the Great Barrier Reef to a final concentration of 170 mg l−1.

Coral and Other Organic Reefs in Geologic Column

AAPG Bulletin, 1950
The several definitions and meanings of the word reef are considered and also the application of the term bioherm proposed by Cumings and Shrock. Reefs from the geological point of view are defined and the characteristics of such reefs are presented. Reefs in the geologic column from the Huronian to and including the Tertiary are described.

Interaction between inorganic nutrients and organic matter in controlling coral reef communities in Glovers Reef Belize

Marine Pollution Bulletin, 2005
We studied the responses of algae, corals, and small fish to elevated inorganic fertilizer, organic matter, and their combination over a 49-day summer period in cages that simulated the coral reef in the remote Glovers reef atoll, Belize. The addition of organic matter reduced while fertilization had no effect on the numbers of herbivorous damsel and ...

Biological and remote sensing perspectives of pigmentation in coral reef organisms

2002
Coral reef communities face unprecedented pressures on local, regional and global scales as a consequence of climate change and anthropogenic disturbance. Optical remote sensing, from satellites or aircraft, is possibly the only means of measuring the effects of such stresses at appropriately large spatial scales (many thousands of square kilometres ...

Organic Matter Oxidation and Aragonite Diagenesis in a Coral Reef

SEPM Journal of Sedimentary Research, 1993
ABSTRACT A combination of field and theoretical work is used to study controls on the saturation state of aragonite inside a coral-reef framework. A closed-system ion-speciation model is used to evaluate the effect of organic-matter oxidation on the saturation state of aragonite.

Observations on organic aggregates in the vicinity of coral reefs

Marine Biology, 1968
The abundance of organic aggregates is reported for a variety of coral-reef sites and surrounding waters. There is no net increase of aggregates forming from dissolved organic matter and streaming off the reefs into the lagoons, though the organic components and the aeration of this water might be conducive to aggregate formation.

Rafting of reef corals and other organisms at Kwajalein Atoll

Marine Biology, 1989
Studies conducted at Kwajalein Atoll (9°N; 168°E) in early 1988 reveal that marine organisms are commonly rafted into the area on drift pumice, drift wood and other flotsam. Coralskeletons on pumice provide the most useful quantitative data because they persist after rafted motile organisms have departed and rafted sessile forms have decomposed or been
