Most of this knowledge, however, is not easily accessible to non-specialists, whether they are involved in environmental management or are interested amateurs, and thus must limit their appreciation of the potential application of foraminifera to problem solving. In spite of this, and as evidenced by the brisk trade in books and samples on eBay and the activities of, say, the Foraminifera.eu-Project, there is a considerable non-specialist interest in foraminifera and their geological and environmental applications.

Many people have provided help and encouragement over the years, without which this book would not have been possible. Later, I benefited from the help and encouragement of L. Blanc-Vernet and B. Thomassin who co-supervised my thesis work, and J.-P. Margerel made available to me his unpublished work on the foraminifera of the bay of Saint Vincent. During this period, I had fruitful collaboration with several colleagues. Among them, G. Cabioch gave me core samples for studying foraminiferal assemblages at a geological time scale; D. Wirrmann took me on to collect, process and study sediment cores; C. Payri allowed me to get rich foraminiferal assemblages from algal substrates; L. Della-Patrona provided me with samples from shrimp farms and, together with C. Marchand, samples from mangrove swamps; J.-M. Fernandez gave me surface samples and core samples from potentially contaminated areas; B. Richer de Forges allowed me to get deeper samples from the northern lagoon; and J.-L. Justine gave me the rare opportunity to open a number of fish guts, for him to collect parasites, and me foraminifera. All of them are warmly thanked for that, and for lively discussion on various research topics. During all this time, I also benefited from a large amount of technical help. Sans eux, ce livre n aurait pas vu le jour.
I owe a great debt of gratitude to a number of people from administrative, technical and research staffs, and to my students who helped me over years during my work. Unfortunately, it is impossible to mention them all here. Finally, I thank my wife, family and friends for having been patient with me, especially during the last months of writing this book. Malheureusement, il est impossible de tous les nommer. Foraminifera have an evolutionary history that extends back to the Cambrian, more than 525 million years ago. Since then, they have radiated and evolved. To date, approximately 60,000 fossil and modern species have been validly recognized (LANGER, 2011), and an estimated 10,000 species (including only planktonic species) are still living (VICKERMAN, 1992), constituting the most diverse group of shelled microorganisms in modern oceans (SEN GUPTA, 1999). These small-sized organisms, usually 0.1 to 1 mm, may be very abundant, and tens of thousands living specimens per square meter may be found in some environments (WETMORE, 1995). Their mineralized tests (shells) usually get preserved in the sediment after the death of the organism and may constitute a major, sometimes the dominant, part of many modern or fossil sediments (fig. 1). They are easy to collect, and their high-density populations provide an adequate statistical base, even in small volume samples, to perform environmental analyses, making them a powerful tool for environmental assessment. Why this book? The aim of this book is to give an overview of the present knowledge on foraminifera from New Caledonia. The fourth part gives a synthesis of the main results published on Recent foraminifera from New Caledonia, and the last and most important part presents the 1043 species in the form of an illustrated atlas with photos and information about the morphology and taxonomy of most of the species.
This inventory will be helpful to professional micropaleontologists, researchers, and students, but its main objective is to offer environmental managers and all person interested in lagoonal environment and protection the access to this invaluable tool for environment monitoring that are benthic foraminifera.

Previous works about foraminifera from New Caledonia The first study of foraminifera from the southwestern Pacific near New Caledonia was carried out by BRADY (1884) during the voyage of H.M.S. Challenger ( ), updated by BARKER (1960). The nearest station was station 177, near Vanuatu (16 45 S E). However, studies concerning directly New Caledonia began much later, with partial and local inventories in coastal samples (GAMBINI, 1958, 1959; RENAUD-DEBYSER, 1965; TOULOUSE, 1965, 1966). These samples allowed MARGEREL (1984) to make the first detailed inventory of foraminifera from the Baie de Saint-Vincent (southwest of New Caledonia). This inventory, unfortunately still unpublished, described 289 species. Several papers were published (DEBENAY, 1985a, 1985b, 1986, 1988a, 1988b, 1988c). Two PhD theses also provided inventories of foraminifera from New Caledonia and Polynesia (ADJAS, 1988), and from New Caledonia including Chesterfield islands (DEGAUGUE-MICHALSKI, 1993). At that time, 585 species were identified. It is schematically composed of a series of NW-SE trending ridges and basins, formed during the geological history of the area, which began around mid-cretaceous time.
The New Caledonia archipelago comprises: the Grande Terre (the largest island, 400 km-long and 50 km wide), extending to the Belep islands and the d Entrecasteaux Reefs to the north and the Isle of Pines to the south (fig. 3), and supported by the New Caledonia Ridge, which is the northern extension of the Norfolk Ridge; the Loyalty islands, on the Loyalty Ridge; Chesterfield and Bellona plateaus, supported by the Lord Howe volcanic chain; Lansdowne Bank and Fairway Ridge; and seamounts along the Loyalty, Norfolk and Lord Howe ridges. Matthew and Hunter volcanic islands are located father to the southeast, on the southern part of the Vanuatu volcanic arc. The main island, Grande Terre, is the third largest island in the Pacific (after New Guinea and New Zealand). It is of continental origin and has a mountainous axis that reaches a maximum altitude of 1,629 m. The Belep islands and Isle of Pines are also mostly continental islands. The Chesterfield islands and Bellona reefs are coral cays along the perimeter of the plateaus, forming large atolls. In dark blue: the main lagoons. 15 14 A Guide to 1,000 Foraminifera from Southwestern Pacific: New Caledonia A prominent dynamic regional feature is the subduction zone between New Caledonia and Vanuatu, where the Australian plate dips under the Vanuatu volcanic arc. The resulting lithospheric deformation (bulge) of the Australian plate explains the uplifted reefs of Grande Terre, Isle of Pines and Loyalty Islands (DUBOIS et al., 1974). Oceanography and climate Hydrological conditions in the southwest Pacific Ocean Water circulation in the southwest Pacific follows complex pathways due to its strong interaction with the complex bathymetry of the region. Those jets feed the western boundary current system: the East Australian Current to the south and the New Guinea Coastal Current that itself feeds the Equatorial Undercurrent to the North, through the Solomon Straits (fig. 4; GANACHAUD et al., 2007).
Surface waters of the EEZ are fed to the south by a branch of the East Australian Current that brings cold and salted waters and to the north by warm and less salted waters coming from the South Equatorial Current. The result is that the west coast receives cooler waters (1-2 C) than the east coast (ROUGERIE, 1986). The characteristics of these waters are strongly influenced by the seasonal variability of the water circulation (VEGA et al., 2005). Strong cooling events off the western barrier reef of New Caledonia have been attributed to wind-driven coastal upwelling. ALORY et al. (2006) developed a simple one-dimensional model based on a heat budget in the mixed layer. This model suggests that upwelling is the dominant process at daily timescale, and that the surface heat fluxes have a smaller influence than upwelling on daily Sea Surface Temperature (SST) variations. This process, however, is strongly modulated by the seasonal variations of the subsurface stratification. Climatic conditions in the southwest Pacific Ocean The climate of the southwest Pacific region, primarily oceanic, is controlled by large-scale atmospheric circulation features that include the trade wind regimes, the Hadley and Walker circulations, the seasonally varying tropical convergence zones, the semi-permanent subtropical high-pressure belt, and the zonal westerly winds to the south (fig. 5). In January, the prominent feature is the trough of low pressure that extends eastward from the monsoonal low centered over northern Australia, while a high-pressure dome sits over southern Australia in July. The resulting monsoon regime is felt west of 170 W throughout the Vanuatu archipelago and the northern part of New Caledonia. The South Pacific Convergence Zone (SPCZ) that extends from east of Papua New Guinea southeastward toward 120 W, 30 S maintains one of the most expansive and persistent cloud bands on earth.
South of 30 S, the atmospheric circulation is characterized by the presence of an anticyclonic belt (MAES et al., 2007). Under the combined effects of the seasonal shifts in the SPCZ and the monsoon regime, the climate in New Caledonia has typically a wet season that extends from January to April with a transition season from June to July and then a dry season from August to December. The main signals at interannual timescales are linked to the variability of the ENSO phenomenon. NORTH EAST TRADES Hawaian Is. Marshall Is.

The axial mountain range also affects rainfalls and, excluding the mountains, the East Coast and the southeast parts of New Caledonia are the wettest.
Sea-level variations During the last million years, sea level had 100 ka cyclic high (sometimes 5 to 10 m above present-day sea level) and low ( m below present-day sea level) stands, leading to several emersions and submersions of the reefs and lagoons (CHEVILLOTTE et al.,2005;chardon et al., 2008; LE ROY et al., 2008). These drastic environmental changes obviously had significant effects on the New Caledonia marine biodiversity. Modern reefs could start growing when the substratum began to be flooded by the postglacial sea-level rise. During the same time, species progressively colonize the lagoon. However, in the region, sea surface temperatures may not have been suitable for corals before around 8 ka, which can explain the late (8,2 ka) formation of postglacial reefs in New Caledonia (CABIOCH, 2001). Another alternative hypothesis is the lack of suitable substrate (accommodation space) before 8 ka. 18 Study area Lagoons and reefs Reefal structures follow the eastern and western coast of Grande Terre, and extend beyond the island, 50 km southward and 200 km northward. They are connected to the sea by deep passes opened at the mouth of submarine valleys downcut by the rivers during the last glacial regression 20,000 years ago. Extended lagoons are also found in the Chesterfield Archipelago, d Entrecasteaux Reefs and Loyalty Islands (mainly Ouvea). New Caledonian reefs include both oceanic (d Entrecasteaux, Loyalty and Chesterfield) and continental reefs (Grande Terre and Isle of Pines). These reefs offer a large diversity of formations, explained by the diversity of environmental forcing, and provide a rich framework that itself supports a large diversity of shallow modern habitats and communities. This is the longest stretch of barrier reef worldwide, since the Great Barrier Reef in Australia is not a linear barrier reef for most of its length, but an assemblage of platform reefs of various sizes and shapes.

Most of this knowledge, however, is not easily accessible to non-specialists, whether they are involved in environmental management or are interested amateurs, and thus must limit their appreciation of the potential application of foraminifera to problem solving. In spite of this, and as evidenced by the brisk trade in books and samples on eBay and the activities of, say, the Foraminifera.eu-Project, there is a considerable non-specialist interest in foraminifera and their geological and environmental applications.

Many people have provided help and encouragement over the years, without which this book would not have been possible. Later, I benefited from the help and encouragement of L. Blanc-Vernet and B. Thomassin who co-supervised my thesis work, and J.-P. Margerel made available to me his unpublished work on the foraminifera of the bay of Saint Vincent. During this period, I had fruitful collaboration with several colleagues. Among them, G. Cabioch gave me core samples for studying foraminiferal assemblages at a geological time scale; D. Wirrmann took me on to collect, process and study sediment cores; C. Payri allowed me to get rich foraminiferal assemblages from algal substrates; L. Della-Patrona provided me with samples from shrimp farms and, together with C. Marchand, samples from mangrove swamps; J.-M. Fernandez gave me surface samples and core samples from potentially contaminated areas; B. Richer de Forges allowed me to get deeper samples from the northern lagoon; and J.-L. Justine gave me the rare opportunity to open a number of fish guts, for him to collect parasites, and me foraminifera. All of them are warmly thanked for that, and for lively discussion on various research topics. During all this time, I also benefited from a large amount of technical help. Sans eux, ce livre n aurait pas vu le jour.
I owe a great debt of gratitude to a number of people from administrative, technical and research staffs, and to my students who helped me over years during my work. Unfortunately, it is impossible to mention them all here. Finally, I thank my wife, family and friends for having been patient with me, especially during the last months of writing this book. Malheureusement, il est impossible de tous les nommer. Foraminifera have an evolutionary history that extends back to the Cambrian, more than 525 million years ago. Since then, they have radiated and evolved. To date, approximately 60,000 fossil and modern species have been validly recognized (LANGER, 2011), and an estimated 10,000 species (including only planktonic species) are still living (VICKERMAN, 1992), constituting the most diverse group of shelled microorganisms in modern oceans (SEN GUPTA, 1999). These small-sized organisms, usually 0.1 to 1 mm, may be very abundant, and tens of thousands living specimens per square meter may be found in some environments (WETMORE, 1995). Their mineralized tests (shells) usually get preserved in the sediment after the death of the organism and may constitute a major, sometimes the dominant, part of many modern or fossil sediments (fig. 1). They are easy to collect, and their high-density populations provide an adequate statistical base, even in small volume samples, to perform environmental analyses, making them a powerful tool for environmental assessment. Why this book? The aim of this book is to give an overview of the present knowledge on foraminifera from New Caledonia. The fourth part gives a synthesis of the main results published on Recent foraminifera from New Caledonia, and the last and most important part presents the 1043 species in the form of an illustrated atlas with photos and information about the morphology and taxonomy of most of the species.
This inventory will be helpful to professional micropaleontologists, researchers, and students, but its main objective is to offer environmental managers and all person interested in lagoonal environment and protection the access to this invaluable tool for environment monitoring that are benthic foraminifera.

Previous works about foraminifera from New Caledonia The first study of foraminifera from the southwestern Pacific near New Caledonia was carried out by BRADY (1884) during the voyage of H.M.S. Challenger ( ), updated by BARKER (1960). The nearest station was station 177, near Vanuatu (16 45 S E). However, studies concerning directly New Caledonia began much later, with partial and local inventories in coastal samples (GAMBINI, 1958, 1959; RENAUD-DEBYSER, 1965; TOULOUSE, 1965, 1966). These samples allowed MARGEREL (1984) to make the first detailed inventory of foraminifera from the Baie de Saint-Vincent (southwest of New Caledonia). This inventory, unfortunately still unpublished, described 289 species. Several papers were published (DEBENAY, 1985a, 1985b, 1986, 1988a, 1988b, 1988c). Two PhD theses also provided inventories of foraminifera from New Caledonia and Polynesia (ADJAS, 1988), and from New Caledonia including Chesterfield islands (DEGAUGUE-MICHALSKI, 1993). At that time, 585 species were identified. It is schematically composed of a series of NW-SE trending ridges and basins, formed during the geological history of the area, which began around mid-cretaceous time.
The New Caledonia archipelago comprises: the Grande Terre (the largest island, 400 km-long and 50 km wide), extending to the Belep islands and the d Entrecasteaux Reefs to the north and the Isle of Pines to the south (fig. 3), and supported by the New Caledonia Ridge, which is the northern extension of the Norfolk Ridge; the Loyalty islands, on the Loyalty Ridge; Chesterfield and Bellona plateaus, supported by the Lord Howe volcanic chain; Lansdowne Bank and Fairway Ridge; and seamounts along the Loyalty, Norfolk and Lord Howe ridges. Matthew and Hunter volcanic islands are located father to the southeast, on the southern part of the Vanuatu volcanic arc. The main island, Grande Terre, is the third largest island in the Pacific (after New Guinea and New Zealand). It is of continental origin and has a mountainous axis that reaches a maximum altitude of 1,629 m. The Belep islands and Isle of Pines are also mostly continental islands. The Chesterfield islands and Bellona reefs are coral cays along the perimeter of the plateaus, forming large atolls.

The resulting lithospheric deformation (bulge) of the Australian plate explains the uplifted reefs of Grande Terre, Isle of Pines and Loyalty Islands (DUBOIS et al., 1974). Oceanography and climate Hydrological conditions in the southwest Pacific Ocean Water circulation in the southwest Pacific follows complex pathways due to its strong interaction with the complex bathymetry of the region. Those jets feed the western boundary current system: the East Australian Current to the south and the New Guinea Coastal Current that itself feeds the Equatorial Undercurrent to the North, through the Solomon Straits (fig. 4; GANACHAUD et al., 2007).
Surface waters of the EEZ are fed to the south by a branch of the East Australian Current that brings cold and salted waters and to the north by warm and less salted waters coming from the South Equatorial Current. The result is that the west coast receives cooler waters (1-2 C) than the east coast (ROUGERIE, 1986). The characteristics of these waters are strongly influenced by the seasonal variability of the water circulation (VEGA et al., 2005). Strong cooling events off the western barrier reef of New Caledonia have been attributed to wind-driven coastal upwelling. ALORY et al. (2006) developed a simple one-dimensional model based on a heat budget in the mixed layer. This model suggests that upwelling is the dominant process at daily timescale, and that the surface heat fluxes have a smaller influence than upwelling on daily Sea Surface Temperature (SST) variations. This process, however, is strongly modulated by the seasonal variations of the subsurface stratification. Climatic conditions in the southwest Pacific Ocean The climate of the southwest Pacific region, primarily oceanic, is controlled by large-scale atmospheric circulation features that include the trade wind regimes, the Hadley and Walker circulations, the seasonally varying tropical convergence zones, the semi-permanent subtropical high-pressure belt, and the zonal westerly winds to the south (fig. 5). In January, the prominent feature is the trough of low pressure that extends eastward from the monsoonal low centered over northern Australia, while a high-pressure dome sits over southern Australia in July. The resulting monsoon regime is felt west of 170 W throughout the Vanuatu archipelago and the northern part of New Caledonia. The South Pacific Convergence Zone (SPCZ) that extends from east of Papua New Guinea southeastward toward 120 W, 30 S maintains one of the most expansive and persistent cloud bands on earth.
South of 30 S, the atmospheric circulation is characterized by the presence of an anticyclonic belt (MAES et al., 2007). Under the combined effects of the seasonal shifts in the SPCZ and the monsoon regime, the climate in New Caledonia has typically a wet season that extends from January to April with a transition season from June to July and then a dry season from August to December. The main signals at interannual timescales are linked to the variability of the ENSO phenomenon. NORTH EAST TRADES Hawaian Is. Marshall Is.

The axial mountain range also affects rainfalls and, excluding the mountains, the East Coast and the southeast parts of New Caledonia are the wettest.
Sea-level variations During the last million years, sea level had 100 ka cyclic high (sometimes 5 to 10 m above present-day sea level) and low ( m below present-day sea level) stands, leading to several emersions and submersions of the reefs and lagoons (CHEVILLOTTE et al.,2005;chardon et al., 2008; LE ROY et al., 2008). These drastic environmental changes obviously had significant effects on the New Caledonia marine biodiversity. Modern reefs could start growing when the substratum began to be flooded by the postglacial sea-level rise. During the same time, species progressively colonize the lagoon. However, in the region, sea surface temperatures may not have been suitable for corals before around 8 ka, which can explain the late (8,2 ka) formation of postglacial reefs in New Caledonia (CABIOCH, 2001). Another alternative hypothesis is the lack of suitable substrate (accommodation space) before 8 ka. 18 Study area Lagoons and reefs Reefal structures follow the eastern and western coast of Grande Terre, and extend beyond the island, 50 km southward and 200 km northward. They are connected to the sea by deep passes opened at the mouth of submarine valleys downcut by the rivers during the last glacial regression 20,000 years ago. Extended lagoons are also found in the Chesterfield Archipelago, d Entrecasteaux Reefs and Loyalty Islands (mainly Ouvea). New Caledonian reefs include both oceanic (d Entrecasteaux, Loyalty and Chesterfield) and continental reefs (Grande Terre and Isle of Pines). These reefs offer a large diversity of formations, explained by the diversity of environmental forcing, and provide a rich framework that itself supports a large diversity of shallow modern habitats and communities. This is the longest stretch of barrier reef worldwide, since the Great Barrier Reef in Australia is not a linear barrier reef for most of its length, but an assemblage of platform reefs of various sizes and shapes.
