Bendinger, Arne. „Marées internes autour de la Nouvelle-Calédonie : dynamique, interactions tourbillon-marée interne et challenge pour le satellite SWOT“. Electronic Thesis or Diss., Toulouse 3, 2023. http://www.theses.fr/2023TOU30336.
Der volle Inhalt der QuelleThe oceanic energy cascade and the associated redistribution of energy from planetary scales to microscales are crucial to achieve climate equilibrium, yet they remain to be fully understood and quantified. Among the submesoscale flow regime which is characterized by equal contributions from rotational (balanced) and non-rotational (unbalanced) effects, it is internal tides (internal gravity waves at tidal frequency) which have been shown to represent a major energy transfer toward dissipative scales. The Surface Water Ocean Topography (SWOT) satellite mission will push forward global sea surface height (SSH) observations of fine-scale physics of combined balanced and unbalanced motions, and their interactions. Our understanding of these processes will ultimately depend on our ability to disentangle these two different dynamical flow regimes. This thesis aims to tackle SWOT SSH observability of balanced and unbalanced motions around New Caledonia, an area with pronounced internal tide activity alongside elevated level of mesoscale to submescale eddy variability located beneath two swaths of SWOT's fast-sampling phase during which SWOT orbited on a 1-day repeat cycle to collect high-frequency measurements. As an initial step, this thesis provides the first comprehensive description of internal-tide dynamics around New Caledonia, an internal generation hot spot in the southwestern tropical Pacific that has not yet been explored in the literature, based on a tailored regional high-resolution (1/60°) numerical modeling effort. Internal tide generation around New Caledonia is associated with the main bathymetric structures, i.e. continental slope, shelf breaks, small- and large-scale ridges, and seamounts, strongly dominated by the semidiurnal tide and low-vertical modes, with a strong signature in SSH. It is found to be a major source of tidal energy propagation toward the open ocean despite enhanced energy dissipation rates close to the generation sites. Mesoscale eddy variability is shown to be a potential source for the loss of tidal coherence (or tidal incoherence) due to eddy-internal tide interactions, either through the refraction of tidal beam energy propagation by mesoscale currents toward the open ocean or by mesoscale-eddy induced variations of barotropic-to-baroclinic energy conversion. Important insight is provided by in-situ observations of autonomous underwater gliders. They reveal the numerical model's realism of internal-tide dynamics while proving to be a suitable in-situ platform to infer internal tides, including SSH signature. SWOT SSH observability of balanced and unbalanced motions represent a challenge around New Caledonia as the internal tide dominates SSH variance at wavelengths similar to those of balanced motion at scales less than 200~km wavelength. Particular emphasis is given to the incoherent tide, which manifests in SSH at scales less than 100~km, while restricting the observability of mesoscale and submesoscale motions. An outlook is given on the impact of internal tides on the mesoscale to submesoscale circulation with promising routes for future work on cross-scale energy exchanges and the closure of the oceanic energy budget. Finally, the comprehensive description of internal-tide dynamics conducted in this thesis has important implications for the New Caledonia marine ecosystem, with the hope of paving the way for the island's efforts in the conservation of marine protected areas

Der volle Inhalt der QuelleThe convergent evolution in growth habit is a fundamental phenomenon linking plant ecology and evolution. Remarkably illustrated in island biotas, this phenomenon has never been identified in the original and megadiverse New Caledonian biodiversity hotspot. Through an approach combining plant architecture, functional traits, taxonomy, phylogeny and environmental data, this thesis analyses the evolutionary history of the scarcely known monocaulous growth habit in New Caledonia. Monocauls are self-supporting woody plants whose cardinal functions rely on a single visible stem. In New Caledonia, they are represented by 182 dicotyledonous species belonging to 41 genera and 30 families and are critically endangered. The repeated evolution of the monocaulie in New Caledonia, resulting from at least 31 independent events, is one of the most remarkable cases of convergence in insular environments. In the genus Atractocarpus (Rubiaceae), monocauly evolved recently two to three times through branch reductions into inflorescences, emphasizing the importance of heterochronic processes in the evolution of growth habit. Monocauly is strongly correlated with several traits illustrating major constraints in functional coordination. The evolution of monocauly is strongly associated with rainforests and ultramafic substrate, and seems to have contributed to the diversification of lineages by niche partitioning. The remarkable convergence toward monocauly in New Caledonia can be explained by four major hypotheses: (i) the structural features of rainforests (related to cyclone frequency and intensity) favoring unidirectional exploration of space, (ii) the edaphic constraints associated with ultramafic substrate favoring architectural pauperization, (iii) the historical absence of large native browsers to which monocauls are particularly sensitive, and (iv) the persistence of rainforest during – and spread-out after – glacial episodes that served as refugia and further provided ecological opportunities

Der volle Inhalt der QuelleNew Caledonia (NC) is one of the main biodiversity hotspots (Myers 1988), this is because of its remarkable plant diversity, its endemism rates, among the highest in the world (79%), and because of the vulnerability of its flora. One of the main originalities of New Caledonia flora is based on the presence of a large number of taxa recognized, due to their phylogenetical positions, as the most ancient extant representatives of angiosperms. For a long time, New Caledonia has been considered as an early upset fragment of the Gondwana (Pelletier 2006) that suffered an interrupted history of isolation which conferred the evolutionary particularities that we observe today. However, recent evidences show that NC has derived from the Australian land during the late Mesozoic (~80 Mya), the island was then submerged during the first half of the Cenozoic (Pelletier 2006) and a reemergence of the island seems to have occurred ~37 Mya (Cluzel et al. 1998). After the reappearance of the island above the sea level, several events of recolonisation occurred and they wrought the biodiversity that we observe nowadays (Pillon 2012). NC presents humid forests which are unique relics; under the influence of climate changes, these forests have virtually disappeared from other regions of the globe (Morat et al. 1986). The lineages of “relictual” angiosperms, mainly subservient to these humid forests, have a great scientific and patrimony value, as they can be considered as genuine windows on the past. These taxa are susceptible to contain primitive characters which have either disappeared in most of the existing flowering plants, or that are still shared by a narrow number of them. The identification and the study of these characters are therefore determinants for the comprehension of angiosperms evolution. Some ecological features of these panchronic species, may have either contributed to the huge radiation of extant angiosperms, or they may have contributed to the ecological settling of angiosperms within the Mesozoic flora, providing them with a developmental repertoire for the subsequent explosion of their diversity. This PhD project aims to study the ecological, anatomical and functional diversity of basal angiosperms and it seeks to analyze the evolutionary patterns of these structural and functional features. We will consider here as “basal” angiosperms a great group of flowering plants that has diverged before the monocot and eudicot node. This group is conformed by the ANITA grade, formed by Amborella (a single species endemic to NC), Nymphaeales (waterlilies and other herbaceous aquatic plants) and Austrobaileyales (aromatic woody plants). The Magnoliid subclass, a clade of flowering of early divergence, which contains plants considered as paleodicots by Cronquist (1988), will be also included in the analysis of the « basal » taxa. More recently, the Magnoliids have been redefined as a clade comprising Chloranthales, Canellales, Laurales, Magnoliales, et Piperales (APG III, 2009). In a second part of the project, a fieldtrip to Mexico will be held in order to include speces belonging to the Chloranthaceae and Schisandraceae, as well as Cabombaceae et Nymphaeaceae, by this means, we will incorporate species belonging to all the orders of the “basal” angiosperms, reinforcing the comparative analysis. This research work will lean on the recent publications of the phylogenetic relations within basal angiosperms

Der volle Inhalt der QuelleThe New Caledonia ophiolite hosts one of the largest obducted mantle section in the world, hence providing a unique insight for the study of upper mantle processes. These mantle rocks belong to an “atypical” ophiolitic sequence, which is dominated by refractory harzburgites but it also includes minor spinel and plagioclase lherzolites. Upper crust is notably absent in the ophiolite, with the exception of some mafic-ultramafic cumulates cropping out in the southern part of the island. Although the New Caledonia ophiolite has been under investigation for decades, its ultra-depleted nature has made its characterization an analytical challenge, so that few trace element data are available, while isotopic data are completely missing. In this thesis a comprehensive geochemical study (major, trace element and Sr-Nd-Pb isotopes) of the peridotites and the associated intrusive mafic rocks from the New Caledonia ophiolite has been carried out. The peridotites are low-strain tectonites showing porphyroclastic textures. Spinel lherzolites are undepleted lithotypes, as attested by the presence of 7-8 vol.% of Na2O and Al2O3-rich clinopyroxene (up to 0.5 wt.% Na2O; 6.5 wt.% Al2O3), Fo content of olivine (88.5-90.0 mol.%) and low Cr# of spinel (13-17). Conversely, harzburgites display a refractory nature, proven by the remarkable absence of primary clinopyroxene, very high Fo content in olivine (90.9-92.9 mol.%), high Mg# in orthopyroxene (89.8-94.2) and Cr# in spinel (39-71). REE contents show abyssal-type patterns for spinel lherzolites, while harzburgites display U-shaped patterns, typical of fore-arc settings.Spinel lherzolites REE compositions are consistent with relatively low degree (8-9%) of fractional melting of a DMM source, starting in the garnet stability field. Conversely, REE models for harzburgites indicate high melting degrees (20-25%) of a DMM mantle source under spinel faies conditions, consistent with hydrous melting in forearc setting. Plagioclase lherzolites exhibit melt impregnation microtextures, Cr- and TiO2-enriched spinels and REE, Ti, Y, Zr progressive increase with respect to spinel lherzolites. Impregnation models indicate that plagioclase lherzolites may derive from spinel lherzolites by entrapment of highly depleted MORB melts in the shallow oceanic lithosphere. Mafic intrusives are olivine gabbronorites with a very refractory composition, as attested by high Fo content of olivine (87.3-88.9 mol.%), very high Mg# of clinopyroxene (87.7-92.2) and extreme anorthitic content of plagioclase (An = 90-96 mol.%). The high Mg#, low TiO2 concentrations in pyroxenes and the anorthitic composition of plagioclase point out an origin from ultra-depleted primitive magmas in a convergent setting. Geochemical trace element models show that the parental melts of gabbronorites are primitive magmas with striking depleted compositions, bearing only in part similarities with the primitive boninitic melts of Bonin Islands. The first Sr, Nd and Pb isotope data obtained for the New Caledonia ophiolite highlight the presence of DM mantle source variably modified by different processes.Nd-Sr-Pb isotopic ratios for the lherzolites (+6.98≤ƐNdi≤+10.97) indicate a DM source that suffered low-temperature hydrothermal reactions. Harzburgites are characterized by a wide variation of Sr, Nd and Pb isotopic values, extending from DM-type to EMII compositions (-0.82≤ƐNdi≤+17.55), suggesting that harzburgite source was strongly affected by subduction-related processes. Conversely, combined trace element and Sr-Nd-Pb isotopic data for gabbronorites indicate a derivation from a source with composition similar to Indian-type mantle, but affected by fluid input in subduction environment

Der volle Inhalt der QuelleWhile scientific progress offers unimaginable opportunities, constraints of industrialization, urbanization and modern technology never cease to reverse the field of the intangible and spiritual. Long spared Oceania remains a privileged space where the impregnation of traditions and nature remained alive and meaningful. “Imagination in Kanak myths” is the subject of our research, the opening of a novel exploratory field which leads to the revelation of the “Real hidden” bases this approach. The contribution of the study and research of the first missionaries, linguists and anthropologists has provided a set of data and myths that describe and interpret the organization of the Kanak society, its customs and traditions. Investigations of ethnology remained away from traditional theories and discoveries of the Imaginary Freud, Jung and Bachelard were precursors. We will call the methods of analysis and investigation of the collective unconscious and depth psychology, to fit the field of mythology Kanak. The implementation of a corpus of myths collected at the beginning of colonization, explains the structural composition of each story, which develops their “genetic identification card”, and imagine a new method of exploring the world of myths. Implementation of “mythocritic” Gilbert Durand adapted and supplemented by mythanalysis, performs an exploratory mythodologie of the imaginary of " sermo mythicus". Constellations of images, symbols and archetypes decrypted in these ancient myths, then reveal the deep semantic as well as joining the universal archetypes. Our aim is to highlight the relevance of previous theories that have revolutionized such fields as psychology, philosophy, and literature up and opening new horizons for the interpretation of oral traditions which are major among the most old Oceania, and to confirm their rich symbolism and their contribution to the knowledge of Anthropos that Leenhard had emphasized

Der volle Inhalt der QuelleWe studied the microbial ecology of an alkaline hydrothermal submarine shallow field (0-50 m) located in Prony Bay (PHF) in the south of New Caledonia (SW Pacific) similar to the deep alkaline hydrothermal site (800m) of Lost City (LCHF) (Mid-Atlantic Ridge). Similarly to LCHF, PHF is an ultramafic hydrothermal system functioning on the basis of serpentinization reactions of the mantle rocks, releasing anoxic, highly alkaline fluids (to pH 11) rich in calcium, and in dissolved hydrogen and methane. The Prony hydrothermal field (PHF) is characterized by large carbonate chimneys emitting fluids with temperatures not exceeding 40 °C. Molecular approaches revealed a prevalence of Bacteria (Firmicutes, Deltaproteobacteria…) over Archaea (Methanosarcinales). Regarding microbial cultures, they were unsuccessful for most major trophic groups (sulfate-reducing bacteria, methanogens) with the exception of fermentative representatives of the phylum Firmicutes. Two novel bacteria belonging to this phylum were isolated. They include (i) Vallitalea pronyensis which is likely associated with hydrothermal vents and (ii) Alkaliphilus hydrothermalis which should be indigenous to alkaline fluids emitted from chimneys since its growth optimal physicochemical conditions match those of fluids. These two bacteria represent the first anaerobic microorganisms isolated from alkaline hydrothermal serpentinized systems so far

Der volle Inhalt der QuelleUnder humid tropical to sub-tropical conditions, weathering processes and supergene mineralization are the main responsible for genesis and release of asbestos fibres. The New Caledonia is one of the largest world producers of Ni ore that is formed by the alteration of ultramafic rocks. Almost all outcrops of geological units and open mines contain serpentine and amphibole, also as asbestos varieties. Mining companies must therefore deal with the health concerns related to environmental exposure to mineral fibres. At present, there is not a technique capable to instantly characterize an asbestos fibre in situ, providing information about size and distribution, morphology, chemical composition and alteration grade. However, the acquisition of all these parameters is necessary for determining the health risk associated to fibre exposition. The employment of specialized tools such as Polarized Light Microscopy associated to Dispersion Staining (PLM/DS) and portable Raman spectroscopy has proved extremely effective in the improvement of performance and rapidity of data acquisition and interpretation, even in the presence of strongly fibrous and altered samples. Regardless of the alteration state, a great variability in morphology was observed (SEM investigation). Preliminary geochemical analyses have proved that the physical-mechanical effect of fluid circulation within the porous of fibres and lamellae, associated to chemical elemental exchange at rock/waters interface, favoured the dissociation of fibres and their release in the environment. A focus was set on fibrous antigorite, recognized as asbestos only by Caledonian legislation, but still not by European law
Berman, Maïa. „Impacts of anthropogenic fires and invasive ants on native ant diversity in New Caledonia : from genes to communities“. Thesis, Montpellier 2, 2012. http://www.theses.fr/2012MON20086/document.
Der volle Inhalt der QuelleHabitat destruction, biological invasions and their interaction are global drivers of biodiversity loss. The New Caledonian hotspot of biodiversity is threatened by both anthropogenic fires and invasive ants: it is important to understand their impacts on its biota. Because biodiversity spans several levels of organisation (from genes to communities) and relates to different attributes (compositional, structural and functional), this thesis takes a hierarchical approach to address this issue. Ants are of great ecological importance, especially in tropical biomes, and their classification into functional groups provides a global framework for analysing their response to disturbance. My aims were therefore to investigate the impacts of anthropogenic fires and invasive ants, and their interaction, on the native New Caledonian ant fauna at different spatial (global, regional, local) and temporal (short and long term) scales, and at different levels of biological organisation (community, species, genes). The study contributes to an improved knowledge of the New Caledonian ants, by revealing the lack of specialised subterranean species, and by investigating island-scale patterns of ant communities, in relation to habitat and invasion. The mechanisms by which fire impacts native ants, either as a standalone process or in association with invasion could be identified. In particular, I show that fire, by creating macro- and microhabitats favoured by invasive ants, facilitates invasion, which then causes further diversity declines, either in the short- (post-burning) or long-term (forest fragmentation). The hierarchical approach used enabled the detection of contrasting trait-derived responses at the species and genetic level, in addition to responses measured at the community level. This study highlights the advantage of a holistic approach to investigating biodiversity-related issues

Der volle Inhalt der QuelleLeptospirosis is an endemo-epidemic zoonotic disease associated with potentially fatal renal, cardiovascular or pulmonary failure. Several aspects of the disease are poorly explored, including infections in children, Jarisch-Herxheimer reactions (JHR) and symptomatic re-infections. The objectives of the studies were the following: to describe disease spectrum and outcome differences in children and adolescents admitted for leptospirosis in a large at-risk population; to quantify frequency of and risk factors for JHR in leptospirosis management; and to assess incidence and characteristics of reinfection by leptospirosis in the Pacific region. Using a retrospective data collection, clinical and laboratory data were obtained on hospitalized confirmed cases in New Caledonia and in Futuna. A case-control study was designed to identify risk factors using a logistic regression model. There are four principal findings from this series of studies with direct implications for clinical practice in those settings. First, leptospirosis in New Caledonia is responsible for a limited number of admissions among children due to milder symptomatic clinical presentation. Second, although generally assumed to be a rare event, the true prevalence of JHR in leptospirosis is unknown in most part of the world. The awareness of this event is probably insufficient considering the significantly high proportion of JHR observed in Futuna. Third, recurrent episodes of symptomatic leptospirosis appear to be non-severe. Finally, specific immunity resulting from a previous episode of leptospirosis with the serovar Copenhageni did not protect against subsequent infection against the same serovar. Future research based those results may provide insights into the still challenging pathogenesis of this complex infectious disease

Der volle Inhalt der QuelleNew Caledonia hosts significant lateritic nickel reserves, and presently became the fifth largest Ni producer in the world. These deposits are generally thought to be closely as- sociated with the intense chemical and mechanical weathering of peridotite bedrock that is a principal source of nickel. Thus, the main ore genesis model for Ni ores in New Caledonia is based on a single per descensum model where most elements (Mg, Ni, and Si) are leached from the surface, particularly, during lateritic soil development. Nickel is then concentrated either in the fine-grained laterite where goethite is the main Ni bearer, the so-called ’lateritic ore’, or below the laterites, in the saprolite level, where nickel occurs as goethite and several types of Mg-Ni silicates, in particular kerolite. Recent mineralogical and structural observations together with mining data have revealed a lot of different types of heterogeneities associated with the distribution and mineralogy of Ni bearing minerals. Therefore, in depth investigations of Ni mobility, its retardation processes along with its governing chemical and hydrodynamic parameters are of big importance for understanding and subsequent prediction of Ni distribution in profiles of New Caledonia. Such an investigation is an objective of the present work. The concept is based on the development of i) a powerful 1D model with particular emphasis on Ni geochemical behavior during ophiolite weathering, its comparison with in situ observations, and detailed understanding of trace elements mobility, and ii) 2D hydro-geochemical model coupled with complex hydrodynamics, that would additionally provide new insight into the structural control on Ni redistribution and mineralization. While the 1D simulations provide a remarkable result for understanding the chemical features that drive Ni retention processes in a profile, 2D model appears to be a powerful tool for understanding how local Ni-enrichments may form. The results of this model show the reactivation of Ni from upper horizons and its concentration in neo-formed silicates in bottom of the saprolite. The reactivated Ni comes mostly from the saprolite horizon due to the redissolution of previously formed Ni-bearing silicates and still persisting in this olivine zone. Modeling has revealed minor contribution of the laterite horizon (Ni-oxi-hydroxides) into the Ni remobilization. The lateral infiltration of water with remobilized Ni from areas such as topographic highs to downstream slope areas leads to the formation of richest deposits in this lower part of profile. The manner of redistribution is fully governed by the topographic slopes, orientation and position of the fractures. Presented models appear to be of importance in attempt of explanation of Ni mineralization processes, revealing the main keys to understanding the control of trace elements mobility in ultramafic environment. The latter gives new insights into the Ni distribution in present day profiles and, therefore, may greatly help in mineral prospecting and forecasting the distribution of future resources

Der volle Inhalt der QuellePhysical forcing drives the space and time discontinuity (patchiness) of plankton in the ocean. The thesis was focused on the role of these forcing on the zooplankton, studied using both acoustic and traditional methods with net sampling. The study was based on two examples. The first one concerns the northwestern Sargasso Sea where high resolution time-series data on 0-200m macrozooplankton abundance and distribution off Bermuda was estimated from volume backscattering strength (Sv) measured with a 153-Khz ADCP. Three types of eddies were identified: a productive cyclonic eddy, the periphery of a mode water eddy, and the periphery of an anticyclonic eddy. Sv values increased during passage of theses eddies, with a more pronounced increase associated with the edge of the cyclonic and the anticyclonic eddies, suggesting a significant biological response to localized upwelling in the high velocity boundary of these eddies. In the second example, spatial and temporal distribution of zooplankton off New Caledonia was studied during two multidisciplinary cruises in 2011. Zooplankton variability was assessed using net sampling together with acoustic measurements (shipborne ADCP, scientific echosounder and TAPS). Higher amplitudes of diel vertical migration (DVM) of zooplankton were associated with higher abundance of large zooplankton and cold waters to the south of the study area, while lower DVM amplitudes in the north were associated with warmer waters and higher abundance of small organisms. These acoustic measurements clearly evidenced the role of physical forcing, particularly mesoscale features, in shaping zooplankton space and time distribution

Der volle Inhalt der QuelleNew Caledonian ultramafic (serpentine) ecosystems are considered as hotspots of biodiversity, partly because of the adaptative pressure exerted by drastic edaphic conditions. Indeed these soils resulting from natural weathering of oceanic mantle could be composed of up to 85 % of iron oxides and are deficient in N.P.K., unbalance for the Ca/Mg ratio and rich in heavy metals Ni, Cr, Mn, Co. Both plant and soil microbes play a vital role in the adaptation to soil conditions mainly heavy metal uptake and tolerance. In our study, we choose endemic species of the genus Tristaniopsis (Myrtaceae) as model plant to study the role of ectomycorrhizal fungi and associated bacteria in plant adaptation to nickel. To investigate the effect of ultramafic soils on ectomycorrhiza and mycorrhizosphere bacteria diversities as well as on the genetic determinants of resistance/adaptation of associated mycorrhizosphere bacteria, 200 ectomycorrhizas were sampled from four different ultramafic sites (3 in Koniambo and 1 in Desmazures forest) vs two non-ultramafic ones from volcano-sedimentary soils (Arama). Molecular characterization of ectomycorrhiza (rRNA ITS) and associated mycorrhizosphere bacteria (16S rRNA) from these samples showed the presence of different fungi (Pisolithus albus, Russula spp., Boletellus spp.) and bacteria (Burkholderia spp., Bacillus spp., Pseudomonas spp.) that can be found in both soils. However, bacteria isolated from ultramafic soils could grow in the presence of Ni up to 20 mmol L-1 and contained cnrA and nreB genes, known to confer heavy metal tolerance, contrary to bacteria isolated from non-ultramafic soils. Moreover, we found a strong positive correlation between heavy metal tolerance and P-solubilizing ability. Further knowledge on functional diversity of ectomycorrhiza-mycorrhizosphere bacteria associations and its role in the adaptation of plants to ultramafic soils would help in the understanding of plant functioning on New Caledonian mine sites
