Abstract. This study presents the evaluation of the performances of satellite altimeter missions by comparing the altimeter sea surface heights with in situ dynamic heights derived from vertical temperature and salinity profiles measured by Argo floats. The two objectives of this approach are the detection of altimeter drift and the estimation of the impact of new altimeter standards that requires an independent reference. This external assessment method contributes to altimeter calibration–validation analyses that cover a wide range of activities. Among them, several examples are given to illustrate the usefulness of this approach, separating the analyses of the long-term evolution of the mean sea level and its variability, at global and regional scales and results obtained via relative and absolute comparisons. The latter requires the use of the ocean mass contribution to the sea level derived from Gravity Recovery and Climate Experiment (GRACE) measurements. Our analyses cover the estimation of the global mean sea level trend, the validation of multi-missions altimeter products as well as the assessment of orbit solutions.Even if this approach contributes to the altimeter quality assessment, the differences between two versions of altimeter standards are getting smaller and smaller and it is thus more difficult to detect their impact. It is therefore essential to characterize the errors of the method, which is illustrated with the results of sensitivity analyses to different parameters. This includes the format of the altimeter data, the method of collocation, the temporal reference period and the processing of the ocean mass solutions from GRACE. We also assess the impact of the temporal and spatial sampling of Argo floats, the choice of the reference depth of the in situ profiles and the importance of the deep steric contribution. These analyses provide an estimation of the robustness of the method and the characterization of associated errors. The results also allow us to draw some recommendations to the Argo community regarding the maintenance of the in situ network.

Abstract. In this work we examine the impact of assimilation of multi-mission-altimeter data and the GRACE/GOCE gravity fields into the finite element ocean model (FEOM), with the focus on the Southern Ocean circulation. In order to do so, we use the geodetic approach for obtaining the dynamical ocean topography (DOT), that combines the multi-mission-altimeter data and the GRACE/GOCE gravity fields, and requires that both fields be spectrally consistent. The spectral consistency is achieved by filtering of the sea surface height and the geoid using profile approach. Combining the GRACE and GOCE data, a considerably shorter filter length resolving more DOT details can be used. In order to specify the spectrally consistent geodetic DOT we applied the Jekeli-Wahr filter corresponding to 241 km, 121 km, 97 km and 81 km halfwidths for the GRACE/GOCE based gravity field model GOCO01S and to the sea surface. More realistic features of the ocean assimilation were obtained in the Weddel gyre area due to increased resolution of the data fields, particularly for temperature field at the 800 m depth compared to Argo data.

Abstract Ocean bottom pressure (OBP) from the Gravity Recovery and Climate Experiment (GRACE) and the Ocean Model for Circulation and Tides (OMCT) are compared globally with OBP computed from altimetry corrected for steric variations from Argo floats from January 2005 to December 2007. Two methods of smoothing the GRACE data are examined. The first uses a standard Gaussian smoother with a radius of 300 km. The second method projects those smoothed maps onto empirical orthogonal functions derived from OMCT in a least squares estimation in order to produce maps that better agree with the physical processes embodied by the model. These new maps agree significantly better with estimates from the steric-corrected altimetry, reducing the variance on average by 30% over 70% of the ocean. This is compared to smaller reductions over only 14% of the ocean using the 300-km Gaussian maps and 56% of the ocean using OMCT maps. The OMCT maps do not reduce variance as much in the Southern Ocean where OBP variations are largest, whereas the GRACE maps do. Based on this analysis, it is estimated that the local, or point-to-point, uncertainty of new EOF filtered maps of GRACE OBP is 1.3 (one standard deviation).

Sea level change is an important indicator of climate change. Our study focuses on the sea level budget assessment of the Arctic Ocean using: (1) the newly reprocessed satellite altimeter data with major changes in the processing techniques; (2) ocean mass change data derived from GRACE satellite gravimetry; (3) and steric height estimated from gridded hydrographic data for the GRACE/Argo time period (2003–2016). The Beaufort Gyre (BG) and the Nordic Seas (NS) regions exhibit the largest positive trend in sea level during the study period. Halosteric sea level change is found to dominate the area averaged sea level trend of BG, while the trend in NS is found to be influenced by halosteric and ocean mass change effects. Temporal variability of sea level in these two regions reveals a significant shift in the trend pattern centered around 2009–2011. Analysis suggests that this shift can be explained by a change in large-scale atmospheric circulation patterns over the Arctic. The sea level budget assessment of the Arctic found a residual trend of more than 1.0 mm/yr. This nonclosure of the sea level budget is further attributed to the limitations of the three above mentioned datasets in the Arctic region.

Abstract. With the focus on the Southern Ocean circulation, results of assimilation of multi-mission-altimeter data and the GRACE/GOCE gravity data into the finite element ocean model (FEOM) are investigated. We use the geodetic method to obtain the dynamical ocean topography (DOT). This method combines the multi-mission-altimeter sea surface height and the GRACE/GOCE gravity field. Using the profile approach, the spectral consistency of both fields is achieved by filtering the sea surface height and the geoid. By combining the GRACE and GOCE data, a considerably shorter filter length can be used, which results in more DOT details. We show that this increase in resolution of measured DOT carries onto the results of data assimilation for the surface data. By assimilating only absolute dynamical topography data using the ensemble Kalman filter, we were able to improve modeled fields. Results are closer to observations which were not used for assimilation and lie outside the area covered by altimetry in the Southern Ocean (e.g. temperature of surface drifters or deep temperatures in the Weddell Sea area at 800 m depth derived from Argo composite.)

Abstract. Based on the sea level budget closure approach, this study investigates the residuals between observed global mean sea level (GMSL) and the sum of components (steric sea level and ocean mass) for the period January 2005 to December 2013. The objective is to identify the impact of errors in one or several components of the sea level budget on the residual time series. This is a key issue if we want to constrain missing contributions such as the contribution to sea level rise from the deep ocean (> 2000m). For that purpose, we use several data sets as processed by different groups: six altimetry products for the GMSL, four Argo products plus the ORAS4 ocean reanalysis for the steric sea level and three GRACE-based ocean mass products. We find that over the study time span, the observed trend differences in the residuals of the sea level budget can be as large as ~0.55mm yr−1. These trend differences essentially result from the processing of the altimetry data (e.g., choice the geophysical corrections and method of averaging the along-track altimetry data). At short time scale (from sub-seasonal to multi-annual), residual anomalies are significantly correlated with ocean mass and steric sea level anomalies (depending on the time span), indicating that the residual anomalies are related to errors in both GRACE-based ocean mass and Argo-based steric data. Efforts are needed to reduce these various sources of errors before using the sea level budget approach to estimate missing contributions such as the deep ocean heat content.

The objective is to identify the impact of errors in one or several components of the sea level budget on the residual time series.

For that purpose, we use several data sets as processed by different groups: six altimetry products for the GMSL, four Argo products plus the ORAS4 ocean reanalysis for the steric sea level and three GRACE-based ocean mass products. We find that over the study time span, the observed differences in trend of the residuals of the sea level budget equation can be as large as ~ 0.55 mm yr−1 (i.e., ~ 17 % of the observed GMSL rate of rise). These trend differences essentially result from differences in trends of the GMSL time series. Using the ORAS4 reanalysis (providing complete geographical coverage of the steric sea level component), we also show that lack of Argo data in the Indonesian region leads to an overestimate of the absolute value of the residual trend by about 0.25 mm yr−1. Accounting for this regional contribution leads to closure of the sea level budget, at least for some GMSL products. At short timescales (from sub-seasonal to interannual), residual anomalies are significantly correlated with ocean mass and steric sea level anomalies (depending on the time span), suggesting that the residual anomalies are related to errors in both GRACE-based ocean mass and Argo-based steric data. Efforts are needed to reduce these various sources of errors before using the sea level budget approach to estimate missing contributions such as the deep ocean heat content.

Le théâtre d’Argos est situé au pied du promontoire que présente l'acropole de la cite, la Larissa, à l'extrémité sud de son flanc est. Le premier état de l'édifice date du premier quart du IIIe siècle avant J. -C. Son bâtiment de skènè comportait un prosternions, probablement ionique, une skènè de plan rectangulaire dotée d'un front de scène perce de cinq larges baies, deux rampes conduisant à l'étage de la skènè et à l'estrade du proskenion et un portique dorique adossé à la skènè. Un cercle de dalles de calcaire, côtoyé de deux tangentes, était inscrit dans l'orchestra, à laquelle on pouvait accéder, de la scène, par un passage souterrain. Le koilon, dont les kerkis centrales étaient taillées dans le rocher et les kerkis latérales construites, avait une capacité de vingt mille places. A l'époque d'Hadrien, vraisemblablement aux frais de l'empereur, l'édifice scénique fut remodelé. Il fut doté d'un pulpitum bas et profond, côtoyé de deux parascaenia, et d'une frons scaenae rectiligne percée de trois portes. Le théâtre, où se déroula dès le troisième siècle avant J. -C. La partie musicale et dramatique des concours nemeens, accueillit, a l'époque impériale, dans son orchestra, des chasses, des combats de gladiateurs et des thetymimesThe argos theater is situated at the southeast extremity of a promontory which is part of the acropolis, named larissa. The first period of this building is dated in the first quarter of the third century B. C. The skene building was formed by : a proskenion, probably of ionic order, a rectangular skene with a frons scaenae which has five large openings, two rampes leading to the first floor of the skene and to the floor of the proskenion and a doric portico on the back of the skene. A circle of limestone slabs, limited on both sides by tangents, is situated in the orchestra. A subterranean way conmected the orchestra with the skene. The central kerkides of the koilon were cut into the rock, though the lateral kerkides built up. Twenty thousand persons could have a seat. In hadrian times, the skene building was transformed, very likely at the expense of the emperor. A low and deep pulpitum, bordered by two parascaenia, and a straight frons scaenae with tree doors, has been constructed. From the third century b. C. , the musical and dramatic performances of the nemea games were organized in the theater of argos. During the imperial period, hunts, gladiators and thetymimes took place in the orchestra

L'objet de cette thèse est l'étude du terrain cultuel argien et de la toile des relations tissées entre les Argiens et leurs dieux par le biais des pratiques religieuses. Celles-ci sont envisagées dans un cadre chronologique large, de l'organisation de la cité d'Argos au VIlle s. av. notre ère, à la visite de Pausanias à Argos au Ile s. de notre ère. À l'aide de toutes les sources disponibles, nous étudions les espaces sacrés et le temps religieux argiens à de multiples échelles : de l'"oikos" aux sanctuaires de la cité, des rites quotidiens aux cultes rendus lors des grandes fêtes annuelles, de l'acte individuel à l'action collective de groupes - professionnels ou associatifs - ou de l'ensemble de la cité. Ce faisant, nous avons cherché à replacer sans cesse les hommes au centre de ces questions afin d'appréhender aussi bien les relations qu'ils entretenaient avec leurs divinités que le rôle de chacun des acteurs, des responsables des charges religieuses aux participants anonymesThe main purpose of this thesis is to clarify the Argive cultic ground and the web of relationships woven between the Argives and their Gods, thanks to numerous religious practices performed from the Eighth century BC, date of the organization of the polis, till the Second century AD, when Pausanias visited this city. Studying the ancient sources at our disposition, I propose an account of the Argive sacred spaces and time, following a range of multiple scales : from the oikoi to the city sanctuaries, from the rites of the everyday life to those performed during annual and civic festivals, from the individual pious acts to those implicating a restricted group - cultic or professional associations - or the city as a whole. Proceeding step by step, I always tried to put men and women at the centre of all these questions in order to show not only the relationship they established with their gods but also their roles as actors - anonymous individuals or those taking hold or sharing a religious charge - playing a part in cultic practices

Argos est l’un des sites majeurs de la Grèce dont l’occupation n’a cessé depuis le Néolithique jusqu’à nos jours. Cette occupation continue se traduit par un patrimoine anthropologique riche, en partie exhumé par les fouilles de l’École Française d’Athènes. Depuis les premières fouilles de Wilhelm Vollgraff en 1902, Argos a livré plusieurs centaines de tombes dispersées dans la ville moderne. Nous adoptons ici une approche bio-archéologique des sépultures, de l’Helladique moyen à l’époque ottomane, ayant livré des restes anthropologiques, en vue d’apporter un éclairage nouveau sur ce qui pouvaient être les conditions de vie à Argos. Un travail d’identification est tout d’abord réalisé afin de rendre exploitable cette collection, en grande partie issue de fouilles anciennes. Pour les 341 individus dénombrés, on a procédé à une estimation du sexe et de l’âge à travers l’étude anthropologique. Une étude croisée est ensuite réalisée faisant appel à des disciplines variées telles que : l’anthropologie dentaire, l’étude des isotopes stables ou encore la tribologie. Cela nous fournit une carte d’identité unique des individus de cette collection. Notre synthèse illustre l’intérêt de ce type d’approche multidisciplinaire en revisitant notre perception de l’Helladique moyen (2000-1600 BC), La confrontation des données bio-archéologiques et des pratiques funéraires permet de confirmer, ou parfois de nuancer, nos connaissances sur la Grèce mésohelladique parfois qualifiée de “tiers monde” de l’Égée. On y entrevoit un monde certes difficile, mais dans lequel la position d’Argos semble finalement relativement confortable en comparaison des sites voisinsArgos is one of the major sites of Greece whose occupation has continued since the Neolithic to the present. This continued occupation results in a rich anthropological heritage, partly revealed by the excavations of the French School of Athens. Since the first excavations conducted by Wilhelm Vollgraff in 1902, Argos has revealed hundreds of graves scattered in the modern city. We adopt here a bio-archaeological approach of the burials from the Middle Helladic to the Ottoman period, which delivered anthropological remains, with the intention to shed new light on what could have been the living conditions in Argos. An identification work is first performed to make usable this collection, which largely results from earlier excavations. For the 341 individuals listed, sex, age and stature could be determined through anthropological study. A crossover study was then carried out using a variety of disciplines such as dental anthropology, the study of stable isotopes or tribology. This provides us with a unique description of the individuals of this collection. Our synthesis illustrates the value of this type of multidisciplinary approach by revisiting our perception of the Middle Helladic period (2000-1600 BC). Comparison of bio-archaeological and burial practices data confirms or sometimes nuances, our knowledge of mesohelladic Greece sometimes called the “third world” of the Aegean. It envisions a world that is certainly difficult, but in which Argos finally seems to be in a relatively comfortable position compared to neighboring sites

Construit sur des arguments littéraires tardifs, le mythe d'un empire argien ne résiste pas à l'analyse. L'étude de la mythologie et de l'histoire argiennes traditionnelles montre que ce mirage est déjà en place à l'époque classique. Il convient donc de revenir aux sources archéologiques pour mener cette étude. Les 15 sites concernés ont fait l'objet d'une véritable reconstruction à partir des vestiges disponibles. Il est possible alors de raisonner. Proposer une estimation de la population de la plaine, site par site, une évolution de sa répartition et une reconstitution de son état sanitaire permet de parler de colonisation intérieure de la plaine au gr. Au milieu du VIIIe s. , le site d’Argos domine déjà très nettement l'Argeia. C'est en effet sur ce seul site que des traces sont laissées par une riche aristocratie dont le mode de vie est décrit. Même s'il est impossible de donner une forme précise aux liens qu'elle a tissés, l'aristocratie argienne, enrichie par l'élevage des chevaux et utilisant l'Héraion, sanctuaire de toute la plaine culturellement unifiée, pour affirmer son pouvoir, domine politiquement l'Argeia. On ne peut faire entrer le culte des tombes mycéniennes et la destruction d'Asine dans ce schéma. L'un et l'autre appartiennent à des logiques qui ne sont pas celles de l'aristocratie argienne. Mais la puissance de cette aristocratie ne se limite pas à la plaine. Elle trouve également son affirmation dans les trépieds et statuettes de bronze argiens, trouves en abondance à Olympie. Tous cependant ne peuvent être des offrandes argiennes. Ces objets magnifient surtout l'habileté des bronziers d’Argos. Car la plaine argienne à l'époque géométrique se caractérise également par son repliement sur soi : à l'exception d'excursions le long de la côte est du Péloponnèse pour son minerai de fer et de la Thyréatide (?), les argiens, forts de leur culture et de leur passé, se ferment aux influences extérieures et notamment aux nouveautés venues de l'orientBuilt on late literary evidences, the myth of an Argive empire cannot be valid. The study of traditional Argive mythology and history proves that this myth already existed in the classical period. Thus we must come back to the archaeological evidences for this study. In the Argive plain, fifteen sites give us traces of the geometric period. For each of them, I try to reconstruct the evolution of the settlement. There it becomes possible to understand how big the population of the Argive plain in the geometric period is, how it lives and how it colonizes the Argeia. In the lg, Argos was already the main site in the plain. An aristocracy lives there; some of its tombs, like the t 45, have been discovered. Its way of life is described. Its wealth was built on horse breeding. It uses the Heraion, sanctuary of all the plain, to assert its authority. So the Argive plain was politically and culturally unified. However the tomb cult and the destruction of Asine in the same period are probably not attributable to the Argive aristocrat. Traces of the Argive aristocracy power are also evidenced through the many Argive bronze tripods and statuettes found in Olympia, even though they cannot all be Argive offers. These objects are more the sign of the manual skill of the Argive bronze smelters. In fact, in the geometric period, the Argive plain was very inward-looking: except for some iron ore harvesting trips along the east coast of Peloponnese and perhaps into the thyreatid, the Argives isolate themselves from foreign and new influences, especially coming from the orient

Les constructions argiennes des deux premiers siècles de n. E. Constituent un panorama presque complet des types de bâtiments des centres urbains impériaux : tombe, nymphée, thermes, aqueducs, temple, odéon et théâtre. Les édifices non dates par des données de fouille peuvent l'être grâce à un système fonde sur les caractéristiques de leur appareil en briques, extensible à l'ensemble de la Grèce. Il est ainsi possible de suivre l'histoire de chaque édifice, ainsi que celle du développement urbain, en relation avec la politique et le contexte socio-culturel. L'identification d'un vaste temple a cour fermée comme serapieion ensuite transforme en asclepieion avec bain thérapeutique, éclaire l'histoire de ce type de bâtiment et l'histoire religieuse d'un jour nouveau. Chaque monument se trouve par ailleurs marque par des innovations architecturales parfois révolutionnaires (voute par tranches, toiture en fermes maçonnées, voute mixte, péristyle d'arcades, nymphée a baldaquin, tholos diptère, opus incertum mixte) et des combinaisons inédites de formes connues (colonnes sur parapet, devant un nymphée ou des bassins de thermes, epicranitis interne sur consoles, arc syrien. . . ) Dans un esprit de baroque mesure, qui témoignent de l'originalité architecturale profonde et inattendue de la province grecqueThe Argive constructions of the first two centuries of our era show an almost complete panorama of the different types of buildings of imperial urban centers: tombs, nymphaeums, baths, aqueducts, temple, Odeon and theatre. Buildings which are undated by excavation data, can be due to a system based on the characteristics of the bricklaying, which applies to the whole of Greece. It is therefore possible to follow the history of each building as well as that of urban development, in relation to the political and socio-cultural context. The authentication of a large temple with an inner court, such as serapieion then transformed into asclepieion with therapeutic bath, throws new light on this type of building as well as on the religious history. Each monument is also marked by architectural innovation, sometimes revolutionary (pitched vault roof with adobe truss, mixed vault, peristyle of arcades, nymphaeum with baldachino, dipteral tholos, mixed opus incertum) and by new combinations of know shapes (columns on parapet, in front of a nymphaeum or thermal bath, internal epicranitis on consoles, Syrian arch. . . ), the whole in a restrained baroque style attesting to the real and unexpected architectural originality of the Greek province

Cette thèse s’inscrit dans une démarche de géographie historique et d’histoire des représentations de l’espace dans l’Antiquité. Elle vise avant tout à essayer de combler une lacune de l’historiographie contemporaine, à savoir celle d’une définition spatiale de ce que recouvre le terme d’Argolide et des réalités auxquelles il renvoie aux époques archaïque et classique. Cette région, située au nord-est du Péloponnèse, n’apparaît proprement sous le nom d'Argolide, dans les textes littéraires, qu’à l’époque romaine. Une unité territoriale préexistait-elle aux périodes plus anciennes ? L’Argolide est-elle un territoire ou une région aux époques archaïque et classique ou n’est-elle qu’une construction historiographique des Anciens et des Modernes ? En partant de l’analyse des territorialités qui se sont exprimées à ces époques dans la péninsule argolique, nous nous interrogeons sur les représentations spatiales qui touchaient cet espace, pour comprendre s’il formait alors chez les Anciens une unité géographique. La péninsule argolique est parcourue de nombreuses identités, qui forment autant de territoires à des échelles variées (celles de la kômè, de la cité ou encore du territoire ethnique), sans pour autant avoir une identité propre et affirmée qui ferait d’elle un territoire. L’Argolide est le résultat d’une intervention active d’Argos dans le domaine des représentations : elle correspond non seulement au lot de Téménos, qui constitua le mythe argien territorial par excellence, mais aussi à l’association des domaines sur lesquels règnent Agamemnon et Diomède dans le Catalogue des Vaisseaux. L’Argolide regroupe donc symboliquement l’ensemble du nord-est du Péloponnèse. Entité mythologique dans l’imaginaire argien qui se diffusa dans l’ensemble de la Grèce archaïque et classique, l’Argolide est également une réalité tangible, puisqu’elle forme une véritable région aux époques archaïque et classique, c'est-à-dire un cadre propice aux interactions économiques, cultuelles ou culturellesThis thesis follows the methodology of historical geography and of the history of spatial representations in Ancient Greece. Its main goal is to fill the gap in contemporary historiography, regarding the spatial definition covered by the term of Argolid and the realities to which it refers in the archaic and classical periods. The Argolid, located in the north-east of the Peloponnese, only appears as a region in literature during the Roman period. Did a territorial unit exist in earlier periods? Is the Argolid a territory or a region in the archaic and classical periods or is it just a histographical construct by the Ancients and Moderns?Starting from the analysis of expressed territorialities at these times in the Argolic peninsula, we study the spatial representations related to this space, in order to understand whether it formed a geographical unit for the Greeks back then. In the Argolic peninsula, many identities coexisted, which formed as many territories at different scales (those of kome, of the city or of the ethnic territory). Nevertheless, the peninsula did not have a clear and strong identity that would have made it a territory.The Argolid is the result of active interventions of Argos in the field of representations: it is linked not only to the lot of Temenos, which constituted the famous territorial Argive myth, but also to the association of the areas under the rule of Agamemnon and Diomedes in the Catalogue of Ships. The Argolid hence symbolically includes all the cities of the northeastern Peloponnese. Originally a mythological entity in Argives’ minds, which was later diffused throughout the archaic and classical Greece, the Argolid is also a concrete reality, since it forms a real region in Archaic and Classical periods, that is to say, a favorable environment to economic, worship or cultural interactions

Full textAbstract:
Ce doctorat d'état sur travaux constitue la synthèse des recherches menées par l'auteur sur des périodes et dans des régions situées aux marges de la civilisation mycénienne. Il s'organise selon trois axes principaux : 1) le développement culturel de la Grèce continentale au bronze moyen et le problème des origines de la civilisation mycénienne; 2) Le poids de l'héritage néolithique dans la genèse et le développement de la civilisation helladique; 3) Les rapports entre le monde helladique et ses marges nord-ouest. Le premier axe offre l'occasion, d'une part, de mettre à jour le tableau d'ensemble de l'helladique moyen dresse par l'auteur il y a quelques années dans un ouvrage collectif (les civilisations égéennes du néolithique et de l’Age du bronze, p. U. F. ); d'autre part, de présenter la documentation encore inédite fournie par la fouille, récemment achevée, de l'habitat mésohelladique de l'aspis d'Argos. Le deuxième axe s'articule autour de cinq aspects du néolithique de la Grèce déjà abordés par l'auteur dans ses précédents travaux, mais qui sont replacés ici dans la perspective de la recherche actuelle : l'occupation des grottes, la nature et la fonction des figurines anthropomorphes, la variabilité des céramiques, la question des échanges et la définition du néolithique final. Le troisième axe de recherche, ancre dans la fouille que l'auteur dirige depuis quatre ans sur le site de Sovjan (Albanie), tourne autour du rôle qu'ont pu jouer, dans le développement de la civilisation helladique, les régions situées sur ses confins nord-ouest (Epire, Albanie, Macédoine occidentale). La question, qui n'a pas encore été traitée de façon systématique, est envisagée à travers l'étude de trois catégories de documents susceptibles de fournir des preuves de contacts entre la Grèce et ces régions au cours de l’âge du bronze : les tumuli au bronze ancien; la céramique à peinture mate au bronze moyen et récent; les armes et la céramique mycénienne au bronze récentThis study is the synthesis of the researches carried out by the author into periods and areas situated on the fringe of mycenaean civilisation. It is organised around three main issues : 1) Cultural development of mainland Greece in the middle bronze age and the problem of the origins of mycenaean civilisation; 2) The importance of the neolithic heritage in the emergence and development of helladic civilisation; 3) The relationships between the helladic world and its north-west border areas. The first issue offers the opportunity, on the one hand, of putting up to date the comprehensive picture of middle helladic Greece drawn up by the author a few years ago in a collective work (the aegean civilisations of the neolithic and the bronze age, p. U. F. ); on the other hand, it allows to present the still unpublished documentation provided by the recently finished excavation of the middle helladic settlement on the aspis of argos. The second issue articulates around five aspects of Greek neolithic, already touched upon by the author in his previous work, but which are here put in the perspective of the current research : the occupation of caves, the nature and function of anthropomorphic figurines, the variability of ceramics, the problem of exchanges and the definition of final neolithic. The third issue, based on the excavation which the author has been in charge of for four years on the site of Sovjan (Albania), deals with the role played, in the development of helladic civilisation, by the areas situated on its north-west border (epirus, albania, western macedonia). This question, which has not yet been dealt with in a systematic way, is considered through the study of three categories of documents likely to provide evidence of contacts between greece and these areas throughout the bronze age : tumuli in the early bronze age; matt-painted ware in the middle and late bronze age; mycenaean ware and weapons in the late bronze age

Full textAbstract:
Les mécanismes d’exhumation des roches de haute-pression basse-température (HP-BT) au sein des zones de subduction sont nombreux, complexes et toujours activement débattus. L’étude des zones de subduction fossiles permet alors de mieux comprendre ces mécanismes, montrant notamment que l’exhumation des roches métamorphiques HP-BT est en grande partie accommodée le long de zones de cisaillement ductiles d’échelle crustale. Ce travail de thèse vise à contraindre la géométrie, la cinématique et la durée de l’histoire tectono-métamorphique des roches de HP-BT du complexe de subduction des Schistes Bleus Cycladiques située en Grèce. Un des objectifs est de contraindre, à différentes échelles, le calendrier de la localisation de la déformation au cours de l’exhumation dans le but de mieux comprendre le comportement mécanique des zones de subduction. Trois méthodes principales d’investigation ont été utilisées : i) une étude de terrain permettant de caractériser la géométrie, la cinématique et la distribution de la déformation, montrant notamment une localisation progressive de la déformation vers la base de l’unité des Schistes Bleus Cycladiques au cours de l’exhumation et le long de zones de cisaillement, ii) des outils de pétrologie métamorphique permettant de contraindre l’évolution P-T des roches métamorphiques au sein de la zone de subduction, et iii) des datations ⁴⁰AR/³⁹AR afin de déterminer le calendrier de l’histoire tectono-métamorphique des Schistes Bleus Cycladiques et de la localisation de la déformation au sein de zones de cisaillement d’échelle kilométrique à millimétrique associées à des degrés de rétromorphose variés. Une corrélation nette est clairement observée entre l’intensité de la déformation, le degré de rétromorphose et les âges les plus jeunes. Un des résultats de ce travail est que la préservation à l’affleurement d’éclogites et schistes bleus n’implique pas forcément une exhumation rapide. En effet, nos résultats suggèrent que l’unité des Schistes Bleus Cycladiques a enregistré une histoire d’exhumation longue d’environ 30 Ma. Le taux d’exhumation n’est donc pas le seul paramètre contrôlant le degré de rétromorphose des unités HP-BT, la remontée le long d’un gradient métamorphique froid dans le canal de subduction et la localisation progressive de la déformation ductile au cours de l’exhumation étant également des facteurs majeursExhumation mechanisms of high-pressure low-temperature (HP-LT) metamorphic rocks in subduction zones are complex and actively discussed. The study of fossilized subduction zones allows a better comprehension of these mechanisms, showing that exhumation of HP-LT rocks is mainly accommodated along crustal-scale ductile shear zones. This study aims at constraining the geometry, the kinematic and the timing of the tectonometamorphic history of the HP-LT Cycladic Blueschist Unit (CBU) cropping out in Greece. A main objective is to constrain the timing of strain localization at different scales during exhumation to better understand the mechanical behaviour of subduction zones. Three principal methods of investigation have been used, including i) a structural fieldwork that allows to characterize the geometry, the kinematic and the distribution of deformations, highlighting progressive strain localization during exhumation toward the base of the CBU and along shear zones, ii) a metamorphic petrology study aiming at determining the P-T evolution of the CBU, and iii) ⁴⁰AR/³⁹AR dating used to constrain the timing of the tectonometamorphic evolution of the CBU and the timing of strain localization within kilometre- to millimetre-scale shear zones showing different degrees of retrogression. We observe an obvious correlation between the intensity of finite deformation, the degree of retrogression and youngest mica ages. A major result of this thesis work is that the preservation of eclogite and blueschist-facies rocks does not necessarily imply fast exhumation rates. Our results instead suggest that the exhumation history of the CBU is relatively long, spanning over ca. 30 Ma. Consequently, it appears that the exhumation rate is not the main parameter controlling the degree of retrogression of HP-LT metamorphic rocks in the CBU compared to progressive strain localization during exhumation along a cold retrograde P-T evolution within the subduction channel

Full textAbstract:
De nombreuses études ont montré l’impact de la déformation sur le système K-Ar, et donc les âges ⁴⁰Ar/³⁹ Ar. Ces études se limitent souvent à une comparaison des âges obtenus dans des roches déformées et un protolithe indemne de déformation. La première partie de cette étude a inversement consisté à étudier la distribution de la déformation à différentes échelles et à décrire finement les gradients d’intensité de la déformation. L’étude a porté sur deux protolithes de nature granitique, associés à une différence d’âge entre leur formation et les évènements tectonométamorphiques faible (< 1 Ma ; massif d’Ikaria) ou élevée (>240 Ma ; massif du Tende). Pour le premier cas, la déformation entraine une perte de 40Ar dans les clastes des phases potassiques, interprétée comme résultant de la réduction des tailles des domaines de diffusion qui n’est pas accentuée par une intensité de déformation croissante. Pour le second cas, l’héritageen 40Ar du protolithe se traduit par la circulation de fluides et de 40Ar externe au système via les structures se déformant activement, produisant parfois un vieillissement des âges grandissant dans la phengite des structures les plus localisantes, alors que sur d’autres coupes il est observé un rajeunissement plus logique. Pour les deux cas,l’interprétation des âges obtenus dans les phases néoformées pendant la déformation est ambiguë entre refroidissement,cristallisation et mélange, et nécessite un examen détaillé des données confrontées aux températures de fermeture possibles. Les interprétations indiquent pour le cas d’Ikaria une localisation de la déformation ductile en moins de 1-3Ma le long d’un gradient de second ordre d’une dizaine de mètre d’épaisseur. La localisation de la déformation à l’échelle d’une zone de cisaillement se réalise plus rapidement dans le cas de l’exhumation post-orogénique d’un MCC(~7 Ma) que dans le cas de l’exhumation de matériel continental impliqué dans un prisme de subduction (~14-10 Ma)Numerous studies have shown the impact of deformation on the K-Ar system, and therefore ⁴⁰Ar/³⁹ Ar ages. These studies often do not provide data characterizing deformation and are limited to a comparison of the ages obtained indeformed rocks and an undeformed protolith. The first part of this study thus consisted in studying the strain distribution at different scales and finely describing strain intensity gradients. The study focused on two granitic protoliths, associated respectively with a difference in age between the formation of the protolith and the age of the tectonometamorphic events that is low (<1 Ma ; Ikaria Island) or inversely high (> 240 Ma ; Tenda massif). In the firstcase study, deformation results in a 40Ar loss in K-bearing phases, interpreted as resulting from the reduction of diffusion domains sizes which is not accentuated by an increasing strain intensity. In the second case study, the 40Arinheritance of the protolith results in fluids and extraneous 40Ar circulation through the actively deforming structures,ages in phengite being increasingly older approaching the most localizing structures in some sections, while others behave in an opposite way, more in line with the progressive strain localization in time. For both cases, interpretation of ages obtained in the newly formed phases during deformation is ambiguous between cooling, crystallization and mixing, and requires a detailed examination of the data confronted with the possible closing temperatures.Interpretations indicate for the Ikaria case study a strain localization in less than 1-3 Ma along a second order gradient of about ten meters in thickness. Strain localization at the scale of a shear zone occurs more rapidly in the case of a post-orogenic exhumation of a MCC (~ 7 Ma) than in the case of the exhumation of continental material involved in a subduction prism (~ 14-10 Ma)

Full textAbstract:
In the framework of the European Commission MAXSIMA project, a large-scale test section, aiming to experimentally investigate the Steam Generator Tube Rupture (SGTR) postulated event, in a relevant configuration for Gen IV MYRRHA reactor, was implemented in the large pool CIRCE facility at ENEA CR Brasimone. The test section is mainly composed by four tube bundles of 31 tubes. Each one of which constitutes a full scale portion of the tube bundle of the Primary Heat eXchanger (PHX) of MYRRHA plant. The bundles are set in 6 inch tubes with a lower and upper tube plate, absolving structural tasks. Water flows upwards in the central tube at 200°C, 16 bar and about 0.1 kg/s, the first rank of six tubes is pressurized at 16 bar by argon for feedbacks on possible domino effect and the outer ranks are composed by opened tubes at the lower and upper end. Lead Bismuth Eutectic alloy (LBE), at 350°C under a cover gas of argon at about 1 bar, flows downwards shell side of the bundle, pushed by a pumping system composed by centrifugal and jet pumps connected in series, for reaching about 80 kg/s. Water tube is fed by external tank and supply line. Two regulation valves and one isolation valve are set for water pressure and mass flow rate regulation and interruption, respectively. Reached the water and LBE stationary conditions of MYRRHA PHX, in terms of pressure, temperature and mass flow rate, the central water tube is pulled upwards by an external hydraulic jack, realizing the tube rupture. Its position is well defined on the tube by a notch worked with machine tools. Four SGTR tests are foreseen to be carried out, one at a time, in the four tube bundles, excluding the necessity to extract the test section from CIRCE main vessel after each test. This paper presents the overall components implemented for carrying out the tests. In particular, the assembling of the whole test section, gas line for pressurizing the water tank and supply line and depressurization line of CIRCE cover gas. It discharges into a 1500 L tank, for collecting possible discharged LBE particulate. The Data acquisition and Control System (DACS) is realized in LabVIEW environment. It allows the remote control of the facility during the preparation phases, tests execution and safe shutdown. PID controllers are implemented for water heating and pressurization and water and LBE mass flow rate regulation. The main commissioning tests carried out and acquired variables by DACS, aiming to check the suitable functioning of all components, are presented. The pre-test numerical analysis of the SGTR experiments in CIRCE facility is performed by 3D Cartesian SIMMER-IV code. The obtained results show that the developed model is able to reach the initial condition of the tests in agreement with MYRRHA stationary conditions. Once reached, the water injection into LBE pool was numerically simulated. The pressure in CIRCE cover gas increased up to the opening rupture disk value of 6 bar in about 10 s, providing a grace period more than enough for carrying out the tests (3 or 5 s) in safe conditions.
