Résumé :
Coral reef fish is one of the main components making up the ecosystem of coral reefs. There is a strong mutual dependence between reef-forming corals and fish that inhabit coral reefs. Various fish species use coral as a food source and habitat. This article describes the impact of coral bleaching on the diversity, density, and biomass of coral reef fish in the waters of Sekotong Bay, West Lombok. Underwater visual census (UVC) methods are used to obtain data on species, the number of individuals per species, and fish size at transect length 70 meters and width 5 meters. Simple linear regression analysis that is used to assess the impact of coral bleaching on the condition of coral reef fish shows that coral bleaching affects the diversity and density of reef fish. This analysis also showed that coral bleaching affected herbivorous fish biomass but not carnivorous fish. This study concludes that the degradation of coral fish in the Sekotong Bay of West Lombok occurs due to various factors, especially the declining health conditions of coral reefs

Résumé :
The coral reefs in Inner Ambon Bay are in the bad category or can even be said to be almost gone where the percentage of coral cover is very small. Efforts to deal with damage to coral reefs have been carried out through rehabilitation programs in Ambon Bay. One of the recommendations given through this program is the need for the participation of coastal communities near the coral transplantation site. It is expected that a good / positive community perception of the existence of coral reefs will encourage the community to participate in efforts to repair damaged coral reefs. For this reason, this research aims to assess public perceptions of damage to coral reefs in Inner Ambon Bay. The survey method was conducted on 318 samples of household heads for primary data collection using a Likert scale questionnaire. The data is analyzed qualitatively and quantitatively. The results showed that people's perception of coral reefs in Inner Ambon Bay was "know". This means that people have knowledge about coral reefs, the benefits of coral reefs, and damage to coral reefs. For this reason, local governments need to manage coral reefs at Inner Ambon Bay in collaboration with local communities, through the establishment of coral reef management institutions at the village level or to utilize coastal and marine management institutions or Kewang institutions in Poka Village, Hunuth Village, and Halong Village to conduct various coral reef rehabilitation program activities.

Résumé :
Globally, coral reefs are under threat from climate change and increasingly frequent bleaching events. However, corals in Kāneʻohe Bay, Hawaiʻi have demonstrated the ability to acclimatize and resist increasing temperatures. Benthic cover (i.e., coral, algae, other) was compared over an 18 year period (2000 vs. 2018) to estimate species composition changes. Despite a climate change induced 0.96°C temperature increase and two major bleaching events within the 18-year period, the fringing reef saw no significant change in total coral cover (%) or relative coral species composition in the two dominant reef-building corals, Porites compressa and Montipora capitata. However, the loss of two coral species (Pocillopora meandrina and Porites lobata) and the addition of one new coral species (Leptastrea purpurea) between surveys indicates that while the fringing reef remains intact, a shift in species composition has occurred. While total non-coral substrate cover (%) increased from 2000 to 2018, two species of algae (Gracilaria salicornia and Kappaphycus alvarezii) present in the original survey were absent in 2018. The previously dominant algae Dictyosphaeria spp. significantly decreased in percent cover between surveys. The survival of the studied fringing reef indicates resilience and suggests these Hawaiian corals are capable of acclimatization to climate change and bleaching events.

Résumé :
The purpose of this study is to investigate the ecological conditions of mangrove ecosystems in the Manado Bay and analyze the suitability of the mangrove ecosystems as a new tourist destination, examine the oceanographic conditions in the Manado Bay area, study the data on the development of coral reef ecosystems to be able to produce artificial coral reefs and produce mangrove areas and coral reefs artificial as a new tourist destination. This research was conducted in April - September 2019 with the location of Manado Bay and the location of the Manado Bay coral reef ecosystem survey set at 3 sample points, equipped with 3 points in front of the BOBOCA Malalayang monument, in front of the Malalayang gas station and ANTRA Sario. Retrieval of coral reef data is by using the Line Intercept Transect (LIT) method. LIT observations were carried out with SCUBA diving at a depth of 6m. Observations were made by recording coral lifeforms found along the transect line, and calculating the percentage of the selection. The data taken is the percentage of dead coral cover, live coral, and type of life form, diversity index taken at 3 sample points. From field observations found on Site 2 (Front of Malalayang gas station) the condition of coral reefs is included in the good category, with the percentage of live coral cover (Hard Coral) of 55%. At this station found various types of coral growth, but the highest at this station is a form of growth of Coral Masive (CM) of 19.2%, while the least found were corals in the form of Coral Mushrooms (Mushroom Coral) with a percentage of 0.4 %. Then Site 3, namely in ANTRA Sario obtained from coral reefs is included in the bad category, with the percentage of live coral cover (Hard Coral) only 7.1%. Coral Diversity in the three survey stations is different. Of the three stations determined above the Tugu Boboca Malalayang site with an index value of 2.54, followed at site 2 namely the Malalayang gas station with an index value of 2.36 and the lowest at site 3 at ANTRA Sario with an index value of 1.33. Furthermore, oceanographic conditions in the Gulf of Manado region are seen in the receding period, most of the air moves westward at the beginning of the period, then moves northeastward in the next period. While in the tide period the water moves northward, starting the period and then it is seen moving northeast and at the end of the period, the east direction.Key words : Coral reef, Oceanographic condition

Résumé :
Coral reefs have great biological and socioeconomic value, but are threatened by ocean acidification, climate change and local human impacts. The capacity for corals to adapt or acclimatize to novel environmental conditions is unknown but fundamental to projected reef futures. The coral reefs of Kāne‘ohe Bay, Hawai‘i were devastated by anthropogenic insults from the 1930s to 1970s. These reefs experience naturally reduced pH and elevated temperature relative to many other Hawaiian reefs which are not expected to face similar conditions for decades. Despite catastrophic loss in coral cover owing to human disturbance, these reefs recovered under low pH and high temperature within 20 years after sewage input was diverted. We compare the pH and temperature tolerances of three dominant Hawaiian coral species from within Kāne‘ohe Bay to conspecifics from a nearby control site and show that corals from Kāne‘ohe are far more resistant to acidification and warming. These results show that corals can have different pH and temperature tolerances among habitats and understanding the mechanisms by which coral cover rebounded within two decades under projected future ocean conditions will be critical to management. Together these results indicate that reducing human stressors offers hope for reef resilience and effective conservation over coming decades.

Résumé :
Subtropical coral reefs along the coast are facing multiple pressures. Mariculture is one of the main sources of such pressure. Oyster culture has become a worldwide phenomenon in coastal ecosystems. Due to the high filtration efficiency of oysters, their culture has helped to purify some coastal waters. However, high-density oyster culture has also had negative effects on coastal ecosystems, including the loss of natural habitat, changes in hydrology, cross infection of corals with pathogenic bacteria, and changes to the structure and function of bacterioplankton communities. In this study, the effect of oyster culture on coral reefs was characterized based on variability in the structure and function of bacterioplankton communities. Using 16S rRNA gene sequencing, a comprehensive bacterioplankton reference database was constructed for coral reef habitats associated with oyster culture and subjected to different disturbance gradients. Small shifts in the surrounding coral reef environment caused by oyster culture disturbance were detected by comparing the structure and function of bacterioplankton communities with biogeochemical parameters. The measured chemical dynamics explained 71.15% of the bacterioplankton community variability between habitats. Oyster culture increased the richness and diversity of bacterioplankton communities. Species composition similarity was highest between the oyster culture area and the nearest coral reef habitat. The spatial turnover in the bacterioplankton community was characterized by less uniform community assembly patterns. The bacterioplankton function of reefs relatively far from anthropogenic disturbance differed from that of those closer to such disturbances. Our results also show that the variability in structure and function of bacterioplankton communities between oyster culture areas and coral reef areas was mainly driven by salinity and ammonium. Oyster culture can impact bacterioplankton community composition and dynamics around coral reef habitats. The results provide an important context for developing frameworks for managing ecological interactions among oyster cultures and coral reef habitats of concern.

Résumé :
Nusa Lembongan islands, Bali have a potential of coral reef diversity. Coral reefs have both ecological and high economic potential so that they are widely used. The economic benefits of coral reefs make these ecosystems very vulnerable to pressure from human activities. One of these human activities is the use of coral reefs in diving tourism activities. This research aimed to determine suitability and carrying capacity of coral reef ecosystem on Nusa Lembongan Island so that it can be recommended to manage coral reef ecosystem strategies to support the use of diving tourism. This study was conducted on six dive sites as observation points Observations on coral reef ecosystems were carried out using the intercept transect (LIT) method, and reef fish observation was carried out using the fish visual census method. Water quality sampling will be done in situ. Diving suitability was carried out by estimating the tourist suitability index (IKW) of six parameters, namely the brightness of the waters, coral community cover, coral life form, reef fish species, coral reef depth and current. The tourism suitability index value for the diving tourism category obtained was 74.07% (Jack Mangrove); 57.41% (Crystal Bay); and 61.11% (Manta Bay). The value for each observation point is included in the appropriate category of 50% -75%. It can be interpreted, that all observation points which are dive sites in Nusa Lembongan have supported diving tourism activities.Keywords: Tourism Suitability Index; Diving; Nusa lembongan.

Résumé :
This study evaluated the status of coral communities at the fringing reefs in the northern South China Sea, and their potential role in maintaining nearby coastline stability of northeastern Hainan Island (Puqian Bay, Hainan Bay). Thirty-nine coral species were recorded with mean coral cover of 5.3%, and are dominated by massive Galaxea, Platygyra and Porites. The coral communities were clustered into two groups (Clu-HNB and Clu-PQB) corresponding to different stable coastal conditions. Coral communities at the Hainan Bay with higher diversity and greater cover corresponded to relatively stable coastline, whereas those at the southern Puqian Bay (with the lowest coral diversity and spatial coverage) corresponded to severe coastline erosion. This work provides some direct evidence that declined coral reefs would weaken their functions to maintain a stable coastline, resulting in severe coastal erosion. It is also useful to help coastal managers and local people pay more attention to the importance of coral reefs in coastal protection and encourage them to change their ways to get sustainable use of coral reef resources. It may be beneficial to inspire or initiate coastal engineering to manage coasts with natural coral reef solution.

Résumé :
Episodes of coral bleaching related to El Niño events have been increasing in frequency and severity. This phenomenon is cited as a major cause of degradation of coral reefs. This study evaluates the effects of coral bleaching on the Caramuanas reef community, which occurred during the southern hemisphere summer of 2009/2010. Within this period the sea surface temperature of 31°C and thermal anomalies up to almost 1°C were recorded. During and after this El Niño event, frequency and severity of bleaching, live coral cover, number of colonies, class size, disease occurrence, and mortality rate were monitored on corals larger than 20 cm in diameter. The samples were taken at twelve fixed transects, in three reef stations. Statistical analysis showed that the severity of bleaching was different between the two periods, during and after the 2010 ENSO event. The Caramuanas reef showed sublethal bleaching effects indicating that this reef is tolerant to bleaching when the temperature anomalies do not exceed 0.75°C within one week.

Résumé :
The coral reefs of Kane'ohe Bay, on the windward coast of O'ahu, Hawai'i, have changed markedly over the last half century. Some of the most spectacular coral reefs in Hawai'i were reported from Kane'ohe Bay in the late 1800's and early 1900's, but with the beginning of extensive military dredge and fill operations during the World War IT era, conditions in the bay began to change dramatically. After the War, rapid urbanization of the area began and conditions in the bay continued to decline until pressure from the public and scientific community led to the diversion of the large sewage discharges in the southeast lagoon to a newly built deep ocean outfall outside the bay in 1977-1978. Although conditions temporally improved, recent surveys indicate that current conditions in the bay are not as favorable as expected. This study provides a time series analysis of changes in coral and algae cover in Kane'ohe Bay based upon a series of coral reef surveys conducted throughout the bay in 1970171, 1983, and 1990. Beginning in 1970171, conditions in the bay were highly degraded and scientists speculated that eutrophication and sedimentation, as a result of urbanization and construction, were the primary cause of an observed decline in lagoon corals communities in the southeast lagoon and an explosive growth of the green "bubble algae", Dictyosphaeria cavemosa, which was smothering corals in the middle lagoon. In . 1983, six years after major sewage discharges were diverted from the bay, surveys indicated dramatic improvements in water quality and the reefs showed signs of recovery. D. cavemosa algae levels, associated with earlier nutrient pollution, plummeted to less than twenty percent of their former abundance levels and coral cover increased by over two hundred percent. Although it was predicted that the coral reefs of Kane'ohe Bay would continue to recover, surveys in 1990 indicate that coral recovery slowed or ceased and the growth of the green "bubble algae", D. cavemosa, more than doubled compared to 1983 levels. In addition to the failure of the t~o dominant coral species Porites compressa and Montipora capitata to continue to recover, almost all of the less common coral species including Pocillopora damicomis, Fungia scutaria, Cyphastrea ocellina, and some others, showed significant declines in reef cover. Although this study was not able to detennine the exact causes of the observed changes in Kane'ohe Bay, it is suggested that high nutrient inputs provided favorable conditions for the changes in coral and algae cover. High nutrient levels are thought to have been derived from a number of sources including chronic sewage pollution, increased sedimentation from runoff, and reef kills associated with acute but large episodes of freshwater runoff. Some of these nutrient inputs may have been the result of non-point source and point source sewage pollution derived from leaky sewer lines, cesspool and septic tank discharges, commercial tour and recreational boat waste discharges, and periodic sewage bypasses from municipal wastewater treatment plants and sewage pump stations. Other nutrients may have been derived from increased sedimentation following extensive land clearance, land development, and highway construction. Additional factors may include a decrease in herbivorous fish species owing to over fishing and the ability of D. cavemosa algae to concentrate nutrients from underlying substrates and excretion from infaunal organisms. Other factors such as increased nutrient recycling from the sediments, possible increased nitrogen fixation from reefs, and natural fluctuations in relative species abundances may also be responsible for some of the observed changes in coral reef community structure. Although rare, the largest nutrient fluxes followed the catastrophic freshwater reef-kill events caused by severe rainstorms in conjunction with low tides and low wind conditions in 1965 and 1987-1988. Although the cause and effect relationship is still uncertain, the highest levels of Dictyosphaeria cavemosa algae ever recorded in Kane'ohe Bay occurred in the years following these storm events. Results of this study indicate that further research is needed to monitor ongoing conditions in the bay and determine what is preventing the reef ecosystem from returning to its former more pristine condition. Because water quality parameters generally remained the same or improved compared to previous polluted conditions, it is suggested that current measures of water quality are not reliable in forewarning against coral reef degradation in Kane'ohe Bay. Although a reduction in all future development in and around the bay would probably help maintain environmental conditions at the status quo, additional regulations and enforcement may be needed to help reduce disturbances caused by existing land and water use. It is suggested that a reduction in nutrient inputs to the bay would be beneficial to reef corals. Recommendations made by the Kane'ohe Bay Task Force outlined in the Kane'ohe Bay Master Plan should serve as a model and be implemented as soon as possible. Continuing assessment of the Kane'ohe Bay coral reef ecosystem and surrounding watershed will then need to be made on a regular basis to ensure that further degradation of the reefs is not occurring.

Résumé :
In Hawaii, abundance of the scleractinian Fungia scutaria is thought to have been in decline in recent years due to disturbances to Kaneohe Bay, where an unusually dense population exists. This study examines factors that could limit population growth in this coral. Sexual reproduction occurred throughout the summer. Experimental data from sperm dilution studies suggested that eggs must be released within 2m of a spawning male for successful fertilization to occur. Field surveys indicated that many patch reefs exhibited high enough densities to yield successful fertilization. However, since field surveys found that only a small percentage (1 %) of juvenile corals (5 cm in length) resulted from settled larvae, post-fertilization processes may be limiting successful recruitment. Asexual reproduction appears to be dominant, with 70% of corals occurring in close aggregations, and 93% of these in aggregations made up of a single color-morph.

Résumé :
Madagascar, a country whose extraordinary levels of endemism and biodiversity are celebrated globally by scientists and laymen alike, yet historically has received surprisingly little research attention, is the setting of the present dissertation. Here, I contribute to the need for applied research by: 1) focusing on the most intensely fished section of the Toliara Barrier Reef, the Bay of Ranobe; 2) characterizing the marine environment, the human population, and the fisheries; and 3) collecting the longest known time-series of data on fisheries of Madagascar, thereby providing a useful baseline for future analyses. In Chapter 1, the bathymetry of the Bay was characterized following a unique application of the boosted regression tree classifier to the RGB bands of IKONOS imagery. Derivation of water depths, based on DOS-corrected images, following a generic, log-transformed multiple linear regression approach produced a predictive accuracy of 1.28 m, whereas model fitting performed using the boosted regression tree classifier, allowing for interaction effects (tree complexity= 2), provided increased accuracy (RMSE= 1.01 m). Estimates of human population abundance, distribution, and dynamics were obtained following a dwelling-unit enumeration approach, using IKONOS Panchromatic and Google Earth images. Results indicated, in 2016, 31,850 people lived within 1 km of the shore, and 28,046 people lived within the 12 coastal villages of the Bay. Localized population growth rates within the villages, where birth rates and migration are combined, ranged from 2.96% - 6.83%, greatly exceeding official estimates of 2.78%. Annual pirogue counts demonstrated a shift in fishing effort from south to the north. Gear and boat (pirogue) profiles were developed, and the theoretical maximum number of fishermen predicted (n= 4,820), in 2013, from a regression model based on pirogue lengths (R2= 0.49). Spatial fishing effort distribution was mapped following a satellite-based enumeration of fishers-at-sea, resulting in a bay-wide estimate of intensity equaling 33.3 pirogue-meters km-2. Landings and CPUE were characterized, with respect to finfish, by family, species, gear, and village. Expansion of landings to bay-wide fisheries yields indicated 1,885.8 mt year-1 of mixed fisheries productivity, with an estimated wholesale value of 1.64 million USD per annum.

This thesis details the geomorphology and timing of the mid-Holocene fossil reef at Cleveland Point, Moreton Bay, Queensland. This research presents the first subsurface data from percussion cores through the reef. Results reveal that Cleveland Point reef initiated quickly after rising seas flooded their foundations 7300 years ago. The reef remained in a "catch-up" growth mode from 7300 to 5700 years ago before reef accretion ceased. Age data suggests that the termination of the reef occurred 5700 years ago and coincided with a hypothesized lowering of sea-level and a possible change in terrigenous sediment distribution in Moreton Bay.

Résumé :
The Oxford English Dictionary defines 'omnifarious' as 'comprising or relating to all sorts or varieties', which quite accurately captures the very nature of octocorals and this thesis. The research reported here, aims to describe undocumented communities of coral reef organisms - the octocorals - which are an emergent dominant component within their threatened ecosystem of the Caribbean. Within the last four decades, coral reefs worldwide have experienced a precipitous plunge in many ecosystem services they provide, and most notably in the Caribbean. The foundation to reef resilience is structured on the ecosystem's ability to repair and restructure itself in the face of environmental shifts. These intricately complex strategies of resilience depend on repair mechanisms provided by a source of biodiversity, much of which remains poorly understood. This work explores many facets of the functioning within this potential future coral reef ecosystem. These reports are one of the most significant contributions to documenting and describing octocoral biodiversity (e.g. species, genetic, and community diversity) of the wider ecoregion of the Mesoamerican Barrier Reef System within the last three decades.

Texte intégral
Résumé :
This synthesis focuses on the history of research on coral reefs within two U.S. National Park Service units in St. Croix, U.S. Virgin Islands: Buck Island Reef National Monument (from 1961 to 2022) and Salt River Bay National Historical Park and Ecological Preserve (from 1980 to 2022). Buck Island Reef National Monument (BUIS) is off the north shore of the island of St. Croix, in the U.S. Virgin Islands. Established in 1961 and expanded in 2001, it is under the jurisdiction of the National Park Service (NPS). Long-term monitoring programs maintained by the NPS and jointly by the University of the Virgin Islands (UVI) and the Virgin Islands Department of Planning and Natural Resources (VIDPNR) provide data on trends in living coral cover and specific coral species from 2000 and 2001, respectively. Disease, thermal stress (indicated by coral bleaching), and hurricanes reduced total coral cover periodically, but cover remained relatively stable from 2007 through the end of 2020. Salt River Bay National Historical Park and Ecological Preserve (SARI) is a national park on the north shore of the island of St. Croix, in the U.S. Virgin Islands. Established in 1992, it is co-managed by the NPS and the Government of the Virgin Islands. Long-term monitoring programs maintained by the NPS and by the UVI with the VIDPNR provide data on trends in living coral cover and individual coral species from 2011 and 2001, respectively. In spite of thermal stress (indicated by coral bleaching), disease, and hurricanes, total coral cover remained relatively stable through the end of 2020. This document also includes results from extensive investigations by the National Oceanic and Atmospheric Administration (NOAA) and from many individual projects including those based out of the underwater saturation habitats Hydrolab and Aquarius from 1977 to 1989, as well as studies from researchers at Fairleigh Dickinson University’s West Indies Laboratory. While not possible to review all of these in detail, this report highlights information considered useful to managers, and scientists planning future research. In 2021, a particularly virulent disease called stony coral tissue loss disease (SCTLD), first noted in 2014 in Florida, and then in 2019 in the U.S. Virgin Islands, started killing corals in BUIS and SARI with the different species showing a gradient of susceptibility. An exact cause or link between this disease and human actions has not been discovered to date. The losses associated with this disease have now exceeded those from any other stressors in these national parks.

Texte intégral
Résumé :
The worldwide market for ornamental saltwater invertebrates supplies the needs of millions of aquarium hobbyists, public exhibitions (i.e., zoos) universities and research institutions. With respect to reef building corals, it is estimated that more than half a million coral colonies/year from a total 93 genera, were exported globally during the period of 1985-1997. International value of retail sale of live coral trade alone is estimated as $78 million in 1997 (not including the illegally, widely smuggled material). The continuous, large-scale collection of marine organisms is responsible, in many places, for the destruction of coral reefs. The expected expansion of the trade further threatens these fragile habitats. While no true captive-bred corals are commercially available, our long-term goal is to develop ex situ inland farming of coral colonies that will circumvent the need for in situ collections and will provide domesticated specimens for the trade and for research. We simultaneously studied two model branching coral species, Stylophora pistillata (Pocilloporidae; in Israel) and Porites (Poritidae; in the US). The proposal included three specific aims: (a) To develop protocols for nubbins (small fragments, down to the size of a single polyp) usage in coral farming;(b) To address the significance of colony pattern formation to the coral trade; and (c) To develop the protocols of using nubbins in physiological and ecotoxicological assays (using oil dispersants, the expression of the stress protein HSP-70, household detergents, etc.). Ten scientific publications (published manuscripts, accepted for publications, submitted to scientific journals, in preparation), revealing results that were related to all three specific aims, originated from this BARD proposal. As a result of the work supported by the BARD, we have now, in hand, original and improved protocols for coral maintenance ex situ, proven expertise on manipulating coral colonies’ pattern formation and biological knowledge on island mariculture of reef corals (from Hawaii and from the Red Sea) amenable for the ornamental trade (for public and private aquaria use, for experimentation). At least one Israeli company (Red Sea Corals, Ltd., KibbutzSaar) is using our methodologies for further developing this new mariculture sector. We are now in the process of introducing the rationale and methodologies to Hawaiian private entities to expand dissemination of the research outcomes.

Economic Valuation of the Ecosystem Services of the Mesoamerican Reef, and the Allocation and Distribution of these Values. Inter-American Development Bank, mai 2021. http://dx.doi.org/10.18235/0003289.

Texte intégral
Résumé :
Coral reefs are one of the most diverse and valuable ecosystems on Earth. The Mesoamerican Reef contains the largest barrier reef in the Western Hemisphere. However, its health is threatened, so there is a need for a management and sustainable conservation. Key to this is knowing the economic value of the ecosystem. “Mainstreaming the value of natural capital into policy decision-making is vital” The value of environmental and natural resources reflects what society is willing to pay for a good or service or to conserve natural resources. Conventional economic approaches tended to view value only in terms of the willingness to pay for raw materials and physical products generated for human production and consumption (e.g. fish, mining materials, pharmaceutical products, etc.). As recognition of the potential negative impacts of human activity on the environment became more widespread, economists began to understand that people might also be willing to pay for other reasons beyond the own current use of the service (e.g. to protect coral reefs from degradation or to know that coral reefs will remain intact in the future). As a result of this debate, Total Economic Value (TEV) became the most widely used and commonly accepted framework for classifying economic benefits of ecosystems and for trying to integrate them into decision-making. This report estimates the economic value of the following goods and services provided by the MAR's coral reefs: Tourism & Recreation, Fisheries, Shoreline protection. To our knowledge, the inclusion of non-use values in the economic valuation of the Mesoamerican Barrier Reef System is novel, which makes the study more comprehensive.

Texte intégral
Résumé :
The Devonian successions in northeastern Manitoba and northern Ontario are integrated in a single stratigraphic framework. To the north, in the offshore Hudson Bay Basin, stratigraphic nomenclaturesare unified and correlated with the successions to the south. The carbon stable-isotope (d13CVPDB) trends for Devonian carbonate rocks are used for regional correlations and are compared with global Devonian isotope trends. Local and global d13CVPDB trends are used to evaluate the position of the Silurian-Devonian boundary in the Hudson Bay Platform. The Devonian succession of the Hudson Bay Platform belongs to the Kaskaskia Sequence and compares with similar carbonate-evaporite successions of the adjacent Williston and Michigan basins. In these basins, two episodes of roughly coeval reef development are present (Emsian-Eifelian and Givetian), with corals and stromatoporoids as main framework constituents. The Hudson Bay Platform reefs and dolomitized facies exhibit significant porosity and have the potential to form hydrocarbon reservoirs, with intervals bearing direct and petrophysical evidence of hydrocarbon charge.
