  author={F. Rougerie and Bruno Wauthy},
  journal={Coral Reefs},
Measurements of interstitial waters in deep wells (0–500 m) in Mururoa and in shallow bores (0–35 m) in Tikehau (French Polynesia) have shown high contents of dissolved nutrients and relatively low salinities, implying a deep oceanic origin. Studies of specific thermal fields within these atolls and carbonate platforms have led to models of deep oceanic water circulation by convection resulting from upward geothermal heat flow. Cold, low-salinity, low-pH, high-CO2, nutrient-rich deep oceanic… Expand
Reef metabolism and endo-upwelling in perspective
Rougerie and Wauthy (1993) have recently advanced the concept of endo-upwelling to explain high rates of metabolism for oceanic coral reefs and atolls. The principal hypothesis advanced in this andExpand
The occurrence and chemical implications of geothermal convection of seawater in continental shelves
[1] Geothermal convection is an important driving force for fluid flow and diagenesis in carbonate platforms, and the similar shape of continental shelves in general suggests that geothermalExpand
Chapter Seven Reef Hydrogeology
Publisher Summary The hydrogeology of islands has an important control on their diagenesis. Large-scale circulation within carbonate platforms may be driven by hydraulic head, geothermal effects, andExpand
Geomorphology and hydrogeology of selected islands of French Polynesia : Tikehau (atoll) and Tahiti (Barrier reef)
The large geomorphological diversity of the Polynesian barrier and atoll reefs can be accommodated by a single heuristic model that is called as geothermal endo-upwelling. The model is based on theExpand
Th e primary function of reef builders, from a geological perspective, is the in situ production of carbonate sediment at a relatively high rate to create a biogenic carbonate body with relief aboveExpand
Geophysical and geochemical evidence of large scale fluid flow within shallow sediments in the eastern Gulf of Mexico, offshore Louisiana
We analyse the fluid flow regime within sediments on the Eastern levee of the modern Mississippi Canyon using 3D seismic data and downhole logging data acquired at Sites U1322 and U1324 during theExpand

The temporal and spatial variability of inorganic nutrient concentrations in overlyingand interstitial-seawater in Checker Reef, Oahu was examined for response to incident wave magnitude andExpand
The temporal evolution of fluid flow through the Tahiti barrier reef traced by Sr isotopes and pore water chemistry
Abstract The internal fluid circulation of the Tahiti barrier reef has been studied with Sr isotopes and pore water chemistry. The study is based on 15 sample series recovered over 2 years from aExpand

This chapter focuses on the past and ongoing investigations of Niue's geology, particularly its carbonate depositional system, history of sea-level fluctuations, hydrogeology, and dolomitization.Expand
Mid-oceanic shallow-water carbonates of the Panthalassa domain: new microfacies data from the Sambosan Accretionary Complex, Shikoku Island, Japan
During the Late Triassic, carbonate platforms expanded on continental shelves and island arcs. They have been studied in detail in the Tethys realm but coeval mid-oceanic shallow-water environmentsExpand


Dolomitization by Groundwater-Flow System in Carbonate Platforms
ABSTRACT Dolomite occurs throughout the subsurface of modern carbonate platforms such as the Bahamas. Groundwater-flow systems must be responsible for delivery of reactants needed for dolomitization.Expand
Internal Hydrology and Geochemistry of Coral Reefs and Atoll Islands: Key to Diagenetic Variations
Diagenetic changes in coral reef carbonates continue to generate both interest and controversy. Considerable attention has been devoted to carbonate porosity (Choquette and Pray 1970, Enos andExpand
Upwelling as a source of nutrients for the Great Barrier Reef ecosystems: a solution to Darwin's question?
The Great Barrier Reef shelf ecosystem is examined for nutrient enrichment from within the seasonal thermocline of the adjacent Coral Sea using moored current and temperature recorders and chemicalExpand
Geothermal springs of the West Florida continental shelf: Evidence for dolomitization and radionuclide enrichment
Abstract On the sea bed of the West Florida continental shelf about 45 km SSW of Ft. Myers, Florida, an 85-km 2 area has been discovered in which six thermal springs discharge warm, chemicallyExpand
Dolomitization of Atolls by Sea Water Convection Flow: Test of a Hypothesis at Niue, South Pacific
The core of the former atoll on Niue island, South Pacific, is extensively dolomitized. A detailed stable isotope study reveals that the dolomites are uniformly enriched in 18O and 13C(δ18O = 2.8‰ ±Expand
Coral-reef hydrology: field studies of water movement within a barrier reef
Water movement through the framework of Davies Reef, a coral reef in the central Australian Great Barrier Reef, was studied using field and laboratory determinations of permeability, tide gaugeExpand

Abstract Upwelling-related intrusions of Coral Sea water into the shelf sea of the central Great Barrier Reef were monitored for 6 months to establish their horizontal extent and coherence over a 350Expand
Petrologic and geochemical constraints on the origin of subsurface dolomite, Enewetak Atoll: An example of dolomitization by normal seawater
Dolomite is present 1,250–1,400 m below sea level in Eocene strata of Enewetak Atoll. Petrographically, the deep Enewetak dolomite postdates brittle compaction of rigid grains in the host EoceneExpand
