Abstract:
Genetic diversity and population structure studies of local olive germplasm are important to safeguard biodiversity, for genetic resources management and to improve the knowledge on the distribution and evolution patterns of this species. In the present study Algerian olive germplasm was characterized using 16 nuclear (nuSSR) and six chloroplast (cpSSR) microsatellites. Algerian varieties, collected from the National Olive Germplasm Repository (ITAFV), 10 of which had never been genotyped before, were analyzed. Our results highlighted the presence of an exclusive genetic core represented by 13 cultivars located in a mountainous area in the North-East of Algeria, named Little Kabylie. Comparison with published datasets, representative of the Mediterranean genetic background, revealed that the most Algerian varieties showed affinity with Central and Eastern Mediterranean cultivars. Interestingly, cpSSR phylogenetic analysis supported results from nuSSRs, highlighting similarities between Algerian germplasm and wild olives from Greece, Italy, Spain and Morocco. This study sheds light on the genetic relationship of Algerian and Mediterranean olive germplasm suggesting possible events of secondary domestication and/or crossing and hybridization across the Mediterranean area. Our findings revealed a distinctive genetic background for cultivars from Little Kabylie and support the increasing awareness that North Africa represents a hotspot of diversity for crop varieties and crop wild relative species.

Abstract:
“Introduced” species of the Algerian coast remains the most undocumented issue in the Mediterranean Sea. Only few studies were dedicated to Introduced species due to the lack of taxonomists. In-depth research on Introduced species along the Algerian coast should provide new data that could explain the spreading mechanisms in the southwestern part of the Mediterranean basin particularly near the Alboran Sea. Introduced species among other related research; of which the outcome is expected in the next few years, is in progress in the southwest Mediterranean basin. The aim of this work is to provide an inventory of available data pertaining to marine species “introduced” in Algerian waters, whether these species were introduced intentionally or accidentally. This large number of Introduced species records covers the period from 1834 to December 2017. Seventy “Introduced” species have been recorded along the Algerian coast, composed by 55.7% true aliens25.7 % range expanding species, 15.7% cryptogenic species and 2,9% vagrant species, with a clear domination of fish (38.57%) and macroalgae (30%). Approximately 348 introduction events have been reported; 64,9 % of them belong to macroalgae and one sighting out of two is done in the central region. The distribution and the status of introduced species in Algeria were evaluated. In total, 20% of the Introduced species can be considered as established along the Algerian coast, in particular the macrophyta, Codium fragile and Ulva lactuca as well as the cryptogenic species, Oculina patagonica, while Asparagopsis armata, A. taxiformis and Caulerpa cylindracea are considered as invasive.

Abstract. The presence of two large-scale cyclonic gyres in the Algerian Basin influences the general and eddy circulation, but their effects on water mass transfer remain poorly characterized. Our study has confirmed the presence of these gyres using the first direct current measurements of the whole water column collected during the SOMBA-GE2014 cruise, specifically designed to investigate these gyres. Using cruise sections and a climatology from 60 years of in situ measurements, we have also shown the effect of these gyres on the distribution at intermediate depth of Levantine Intermediate Water (LIW) with warmer (∼ 0.15 ∘C) and saltier (∼ 0.02) characteristics in the Algerian Basin than in the Provençal Basin. The Algerian Gyres, combined with the effect of anticyclonic Algerian Eddies, also impact horizontal density gradients with sinking of the isopycnals at the gyres' centers. Temporal cross-correlation of LIW potential temperature referenced to a signal observed southwest of Sardinia reveals a timescale of transit of 4 months to get to the center of the Algerian Basin. The LIW potential temperature and salinity trends, on average in the basin interior, are estimated to be +0.0022 ± 0.0002 ∘Cyr-1 and +0.0022 ± 0.0001 yr−1, respectively, over the 1968–2017 period and accelerating to +0.048 ± 0.003 ∘Cyr-1 and +0.0076 ± 0.0009 yr−1 over the 2013–2017 period.

Abstract:
Olive tree with its main final product, olive oil, is an important element of Mediterranean history, considered the emblematic fruit of a civilization. Despite its wide diffusion and economic and cultural importance, its evolutionary and phylogenetic history is still difficult to clarify. As part of the Mediterranean basin, Algeria was indicated as a secondary diversification center. However, genetic characterization studies from Maghreb area, are currently underrepresented. In this context, we characterized 119 endemic Algerian accessions by using 12 microsatellite markers with the main goal to evaluate the genetic diversity and population structure. In order to provide new insights about the history of olive diversification events in the Central-Western Mediterranean basin, we included and analyzed a sample of 103 Italian accessions from Sicily and, a set of molecular profiles of cultivars from the Central-Western Mediterranean area. The phylogenetic investigation let us to evaluate genetic relationships among Central-Mediterranean basin olive germplasm, highlight new synonymy cases to support the importance of vegetative propagation in the cultivated olive diffusion and consolidate the hypothesis of more recent admixture events occurrence. This work provided new information about Algerian germplasm biodiversity and contributed to clarify olive diversification process.

Abstract. We present data collected in the framework of the Algerian BAsin Circulation Unmanned Survey (ABACUS) project. The main objective of ABACUS is the monitoring of the basin circulation and of the surface and intermediate water masses' physical and biological properties in a key region of the Mediterranean Sea circulation. Data presented here have been collected through deep glider cruises in the Western Mediterranean Sea during the autumns of 2014, 2015 and 2016; activities at sea are expected to be repeated during the coming years, so that the dataset will be extended. Glider missions were conducted in the Algerian Basin, between the island of Mallorca and the Algerian coast. Across the three glider missions, eight repeated transects were completed which enabled us to investigate the basin-scale circulation and the presence of mesoscale structures, utilising both the adaptive sampling capabilities of the gliders and the higher resolution of the data. After collection, all data passed a quality control procedure and were then made available through an unrestricted repository host by the SOCIB Data Centre at https://doi.org/10.25704/b200-3vf5. The actual dataset spans three autumn seasons, providing an important contribution to the data collection in the chronically undersampled Algerian Basin. Temperature and salinity data collected in the first 975 m of the water column allowed us to identify the main water masses and describe their characteristics, improving the understanding of the dynamics of the region. On the timescale of the project, data show a large variability in the surface layer and reduced variability in the intermediate and deep layers. Our measurements have been successfully compared to data previously collected in the area from 1909 to 2011. Results showed similar overall distribution, ranges and variability to the historical data, with no outliers in the surface or deep layers.

Abstract:
Abstract. The circulation of the western Mediterranean Sea (WMED) is dominated by highly variable and heterogeneous mesoscale circulation that is strongly driven by the formation and propagation of eddies (cyclonic and anticyclonic) mainly acting in the Algerian Basin. In order to investigate the spatial and temporal distribution of eddy generation and their respective paths in the Algerian Basin, the most energetic WMED portion, we use an automated detection and tracking hybrid method applied to 24 years of sea level anomaly (SLA) data. The algorithm is based on the computation of the Okubo–Weiss parameter in SLA closed loops and has been modified in order to fill the gaps in single eddy tracks. In this work we analysed both cyclonic and anticyclonic structures, but the conclusions will be focused mainly on anticyclones with a lifespan longer than 3 months, as they are characterized by higher kinetic energy, thereby potentially contributing to a large extent to the mesoscale characterization of the basin. In particular, we find that anticyclonic short-life eddies mostly occur in the northern portion of the domain, north of 39∘ N along the North Balearic Front (NBF). Such short-life eddies, labelled frontal eddies (FEs), are characterized by low translational velocity and a highly variable direction of propagation. We found a weak seasonality in their formation, with maxima in fall and winter. By contrast, anticyclonic longer-life eddies tend to arise in the southern part of the basin along the Algerian Current, with a clear maximum in spring. All the structures (both cyclonic and anticyclonic) originating along the Algerian Current are known as Algerian eddies (AEs). According to previous studies, we observe that these anticyclonic eddies mainly form east of 6.5∘ E and move eastward along the African coast to the Sardinia Channel, where they detach from the coast, continuing offshore and following the cyclonic intermediate circulation. We detect a region between 4.5 and 6.5∘ E where such eddies tend to converge and terminate their life. Finally, the analysis suggests that eddies formed in the northern and in the southern part of the Algerian Basin present some physical differences such as lifetime, kinetic energy and vorticity. Furthermore, the connection between the two parts in terms of eddy tracks is limited to a very small number of southbound (FEs) or northbound (AEs) structures crossing 39∘ N.

Abstract:
The objective of this study was to determine the population distribution and some biological aspects for fish stock assessment of the greater forkbeard Phycis blennoides along the Algerian basin. The distribution of P. blennoides (3418 individuals) was studied using data collected between 170–779 m depth during two bottom trawl surveys developed on 2003 and 2004. Additionally, some biological parameters were obtained from 1050 individuals sampled from commercial fisheries in Algerian ports (i.e. Annaba, Azeffoun, Dellys, Cap Djinet, Zemmouri, Bouharoun, Algiers, La Madrague, Cherchell, Tenes and Mostaganem) during the period 2013–2017. P. blennoides sampled from bottom trawl surveys showed a depth related distribution with the largest individuals being found at 600–800 m depth and the smallest at shallower depths. Density and biomass varied with depth and density also with longitude, while biomass showed no pattern with longitude. Recruitment was recorded in the eastern sector of Algeria during winter, for individuals sampled by bottom trawl surveys. Young P. blennoides entered commercial fisheries in summer, with an overall sex ratio skewed towards males (1F:2.18M). The size at first maturity (L 50) was 24.30 cm and 30.39 cm for males and females, respectively. The age at 50% maturity was 2–3 years for specimens collected by a bottom trawl survey in 2003 and commercial fisheries, but 3–4 years for the bottom trawl survey in 2004.

Abstract A previous record of the alien crab Callinectes sapidus from the Algerian coasts was based on a photograph provided by a fisherman showing the dorsal side of a single individual. In this contribution, we confirm this presence in the mouth of the Mafragh Estuary in eastern Algeria, where four individuals of this species were found on 19 November 2019. The specimens examined are one female (60 mm CL, 125.9 g) and three males (60-66 mm CL, 120.4-176.8 g). This discovery confirms the presence of this species in the southwestern Mediterranean Basin where it could become invasive in suitable habitats.

Abstract:
The Mediterranean Salt Giant (MSG) is a thick layer of Messinian evaporites (up to 4 km) that is thought to be deposited during an extreme paleo-environmental event known as the Messinian Salinity Crisis (MSC). After decades of research, there is not yet a consensual model explaining the emplacement and the evolution of the MSG. This is due to the absence of samples of the deep offshore MSG. Past scientific drilling operations were limited to the topmost MSG records because of the risks of intersecting zones of hazardous fluids and overpressure linked to evaporites. The European project SALTGIANT, in which the work of this thesis fits into, is dedicated to understanding the formation of the MSG and its implications for the microbial life, the drilling hazards and the geo-economics of the Mediterranean region and the history of oceanography. In that framework, this thesis aims to improve our seismic images of the offshore MSG and to use the new results to update our understanding of the Messinian salt tectonics. This work is focused on the Algerian basin, in the south-western Mediterranean Sea, where the salt was deposited in an already contractional tectonic setting. I compile, reprocess, and interpret legacy academic seismic data acquired in the central Algerian basin. The re-processing is designed to improve as much as possible the salt and pre-salt structures. It relies on an integrated approach combining geophysics and geological interpretation to iteratively build the velocity model. The new results display a better imaging of salt structures and the seismic facies variations. They shed a new light on the tectono-sedimentary evolution of the central Algerian basin, highlighting the presence of seismic fluid indicators evidencing an active fluid circulation in the basin and its margins. Interpretation of the new seismic sections is done following the most recent nomenclature of the MSC seismic markers. New isochores and thickness maps are produced and compared with the spatial distribution of the salt structures. I interpret contractional salt tectonic structures, such as buckle folds, squeezed diapirs and related salt sheets as evidence of regional thick-skinned shortening episodes. I suggest that extensional stage of the salt system (where the deformation is driven by gravity loading) was short-lived, and that many salt structures were driven by contractional tectonic loading during the Plio-Quaternary. I demonstrate that the initial shortening-related salt deformation in the late Messinian was focussed along the Algerian margin and later shifted outward toward the Balearic margin in the Plio-Quaternary. The shifting of the deformation front is interpreted to be a result of the thickening and strengthening of the overburden. The second peak of deformation may have reactivated faults along the Emile-Baudot escarpment with thick-skinned deformation. I also observe a variation in the intensity of the salt deformation along the margin from SW to NE, which I associate to variable tectonic loading applied along the Algerian margin or the pre-shortening distribution of salt. Fluid indicators are imaged within the Plio-Quaternary of the Algerian basin. They could be thermogenic or biogenic gas sourced from the Messinian Upper Unit, or from the pre-salt, migrating through a hydro-fractured salt. The new results also evidence numerous volcanic structures within the Formentera basin. The distribution of this volcanic edifice could affect fluid circulation, resulting in small-wavelength surface HF anomalies observed locally.

Abstract:
This study presents an integrated evaluation of the burial and thermal history of an exhumed (uplifted and eroded) basin, and investigates the implications for the evolution of reservoir quality of the Ordovician sandstone in the Illizi Basin, Algeria. Complementary techniques including sonic compaction analysis, apatite fission track analysis, thermal maturity analysis, fluid inclusion microthermometry, and sandstone petrography are integrated to provide calibration for burial and thermal history models and diagenetic forward modelling, in order to predict variations in sandstone reservoir quality across the study area. The Illizi Basin has been structurally modified due to multiple exhumation events, including the uplift of the Hoggar Massif, which resulted in exhumation of the flanking sedimentary basins over a distance of 1,500 km from north to south. This study presents new apatite fission track data and analyses that constrain the onset of major exhumation in the Illizi Basin to the Eocene with exhumation magnitudes estimated to be 1-1.4 km in the study area. The study area contains a multi trillion cubic foot gas-condensate accumulation within a large four way dip closure. Hydrocarbon generation occurred during two main phases in the Carboniferous and the Mesozoic, but ceased during Cenozoic exhumation. Due to the Cenozoic tilting of the Illizi Basin in response to the uplift of the Hoggar Massif to the south, the present-day structural trap is interpreted to have formed after the main hydrocarbon generation phases. Therefore, alternative charging mechanisms of this post-peak burial trap are required and explored. In addition, new fluid inclusion data provides evidence of a significant fluid flow event within the Illizi basin, triggered by Cenozoic exhumation. Brines hosted present-day in the Ordovician sandstone in the study area are shown to be genetically linked to Triassic-Liassic evaporites deposited over 400 km to the north. Overpressure dissipation during exhumation is proposed to be a potential driving mechanism for the late stage remobilization of deep brines. A major pre-drill risk in many North African Paleozoic plays relates to sandstone reservoir quality, largely due to extensive quartz diagenesis. The Ordovician reservoir in the study area is characterised through petrography and core analysis, and the impact of burial and thermal history on the reservoir quality is investigated through diagenetic forward modelling. Results indicate that facies and variations in thermal history are a major control on preserving reservoir quality. This study demonstrates the importance of integrating the burial and thermal history, depositional facies and diagenetic history during predictive reservoir quality studies, particularly in exhumed basins where the burial and exhumation history may be complex, and present-day depth or geometry is not indicative of the past. Methodologies and implications from this study could be applied to exhumed basins in general.

Abstract:
Les données de la campagne océanographique SOMBA-GE2014, nous ont permis de mettre en évidence la présence des gyres algériens via des mesures de courant. Les radiales de température et salinité obtenues à travers le bassin ont permis la visualisation de l'influence des gyres algériens sur la répartition hydrologique. En effet des eaux levantines intermédiaires jeunes s'étendent depuis la veine d'eau remontant le plateau sarde vers l'intérieur du bassin algérien, sous forme de patchs. Des climatologies du cœur de la LIW et de WIW couvrant la période 1960 à 2017 dans le bassin Algéro-Provençal, ont été produites grâce à la base de données Méditerranéenne de profils de température et salinité et des nouvelles méthodes de détection. Un transport de LIW vers l'ouest, depuis la veine sud de la Sardaigne vers l'intérieur du bassin algérien en suivant la périphérie des gyres algériens est mis en évidence par cette climatologie et confirmé par la corrélation croisée du signal de refroidissement observé durant les années 80. L'estimation des tendances des caractéristiques de la LIW et WIW contribuent à documenter leur évolution. L'accélération du réchauffement observée dans tout le bassin à partir de 2010 est alarmante. Les observations par les gliders ont permis d'appuyer nos conclusions quant à l'efficacité des structures de méso et de sous-méso échelle pour le transport des masses d'eaux vers l'intérieur du bassin Algérien. En effet nous avons observé des parcelles de WIW, LIW et WMDW à l'intérieur du bassin Algérien dont les caractéristiques sont plus marquées que les eaux adjacentes
Data from the SOMBA-GE2014 oceanographic cruise, allowed us to highlight the presence of Algerian gyres via current measurements. The temperature and salinity sections obtained across the basin allowed the visualization of the influence of the Algerian gyres on the hydrological distribution. Indeed, young intermediate Levantine waters extend from Saridinian LIW vein towards the interior of the Algerian basin, in the form of patches. LIW and WIW core climatologies covering the period 1960 to 2017 in the Algerian-Provençal basin were produced using the Mediterranean database of temperature and salinity profiles and new detection methods. A westward transport of LIW from the southern vein of Sardinia to the interior of the Algerian basin following the periphery of the Algerian gyres is highlighted by this climatology and confirmed by the cross-correlation of the cooling signal observed during the 1980s. The estimation of trends of LIW and WIW characteristics help to document their evolution. The acceleration of warming observed throughout the basin from 2010 is alarming. Glider observations have supported our conclusions regarding the effectiveness of mesoscale and submesoscale structures for the transport of water masses into the interior of the Algerian basin. Indeed, we observed WIW, LIW, and WMDW parcels within the Algerian Basin with more pronounced characteristics than adjacent waters

Abstract:
La marge algérienne est un domaine complexe, bordé au sud par les zones internes des Maghrébides (AlKaPeCa) qui chevauchent les zones externes telliennes vers le sud. La partie offshore de ce système constitue un bassin d‘arrière arc où s‘est déposée une série sédimentaire mio-pliocène reposant sur un substratum de nature et d‘origine variables spatialement. L'objectif de ce travail a consisté à analyser et modéliser le fonctionnement des systèmes pétroliers et à quantifier les volumes d‘hydrocarbures accumulés. Avant de procéder aux différentes modélisations numériques, stratigraphiques et thermiques, un modèle géologique conceptuel a été élaboré sur la base des données de géologie de terrain et de sismiques. La continuité terre- mer du socle kabyle a permis une extrapolation stratigraphique entre des formations oligo-miocènes en affleurement et les unités acoustiques définies dans le bassin offshore. L‘analyse tectonique dans les deux domaines a abouti à une évolution en trois phases : (1) syn-rift où le bassin a été ouvert en transtension à partir de l‘Oligocène supérieur-Aquitanien, (2) phase post-rift durant laquelle il y a eu le développement des bassins intra-arcs, la collision AlKaPeCa- Afrique et le magmatisme, (3) phase d‘inversion où la marge devient active essentiellement à partir du Quaternaire. En définissant l‘ensemble des éléments des systèmes pétroliers avec des incertitudes variables, la simulation du fonctionnement de ces derniers par modélisation de bassin 2D/3D a montré des possibilités d‘accumulation d‘huile et de gaz majoritairement près de la marge, entre 20 et 65 km de la côte avec un maximum de portée de 70 km dans le golfe de Bejaia
The Algerian margin is a complex domain, limited to the south by the Maghrebian internal zones (AlKaPeCa) that overthrust the external Tellian zones southward. The offshore part of this system constitutes a back-arc basin, where a mio-pliocene sedimentary series were deposited over a substratum of laterally variable origin and nature. The goal of the present work consisted in analyzing and modelling the petroleum system at work and calculating hydrocarbon volumes. Before proceeding to different numerical basin, stratigraphic and thermal modelling, a conceptual geological model is required and was performed based on field geological studies and stratigraphic and structural interpretations of the seismic profiles. The extension of the continental crust beyond the foot of the margin, allows determining a chronostratigraphic model by extrapolation of the outcroping oligo-miocene formations onshore to the acoustic pre-messinian units defined in the offshore basin. Besides, a tectonic analysis in both onshore and offshore domains gave rise to three main steps of evolution: (1) syn-rift phase where the basin was opened by transtension since Late Oligocene- Aquitanian, (2) post-rift phase in which intra-arc basins were developed, AlKaPeCa and Africa docked and magmatism activity took place, (3) inversion phase where the margin became active mainly since Quaternary times. After defining the different petroleum system elements taking into account variable uncertainties, the 2D/3D petroleum system model depicts possibilities of oil and gas accumulations mainly close to the margin, between 20 to 65 km from the coastline to the north with a maximum range of 70 km in the Bejaia Gulf

Abstract:
L'inversion des marges passives apparaît comme le premier stade vers l'initiation de nouvelles zones de subduction. Cette étape cruciale dans la tectonique des plaques soulève néanmoins encore de nombreuses questions. L'étude des marges actuellement réactivées en compression apparaît ainsi comme essentielle pour mieux comprendre ce processus. Ces marges sont peu nombreuses, situées dans des contextes géodynamiques variés, et les facteurs déterminant leur évolution mal contraints. Située au nord de l'Afrique, la marge algérienne fait partie de ces rares exemples potentiels à travers le monde. L'évolution de cette marge formée au Miocène en contexte d'arrière-arc s'intègre dans le puzzle complexe de l'histoire de la Méditerranée occidentale. Elle est depuis quelques millions d'années réactivée en compression dans le cadre de la convergence lente entre les plaques européenne et africaine, générant un potentiel sismogène fort au nord de l'Algérie. La relative jeunesse du bassin algérien, la charge sédimentaire, les forces aux limites compressives, constituent des conditions favorables à la formation d'une future subduction. A la suite des travaux menés depuis une dizaine d'années, les principales lacunes de connaissances identifiées portent sur (1) la structuration profonde du bassin algérien et de sa marge sud (type de marge, nature du socle,dimension et nature de la transition océan-continent, style et distribution de la déformation compressive), et (2) l'histoire de l'évolution cinématique et géodynamique du bassin, ce qui limite à l'heure actuelle une analyse approfondie des modalités d'inversion de cette marge. L'étude menée se focalise sur la marge centre-algérienne, dans le secteur de Tipaza (à l'ouest d'Alger), un endroit clé pour la compréhension des mécanismes d'ouverture du bassin algérien. Le traitement et l'analyse de nouvelles données de sismique profonde grand-angle et multitraces acquises dans le cadre du projet franco-algérien SPIRAL (Sismique Profonde et Investigations Régionales en Algérie, 2009) ont notamment permis de déterminer la structure crustale du bassin algérien et de sa marge sud, ainsi que la structuration pseudo-3D d'une structure spécifique au secteur d'étude constituée par le haut topographique sous-marin de Khayr-al-Din. L'analyse de la structure profonde de la marge indique un certain nombre de structures héritées de son évolution complexe : (1) une croûte de nature continentale de plus de 15 km d'épaisseur sur le haut de marge (banc de Khayr-al-Din), (2)une croûte fine de nature océanique de 5-6 km d'épaisseur dans le bassin incluant des vitesses légèrement élevées à sa base (7,2 km/s - 7,3 km/s), (3) des similitudes avec des marges formées dans des contextes de déformation transformante, (4) un approfondissement progressif de l'ensemble de la pile sédimentaire et l'épaississement des sédiments Plio-Quaternaire, depuis le bassin profond distal vers le pied de marge,coïncidant avec (5) une flexuration à grande longueur d'onde du socle. Les résultats obtenus apportent de nouvelles contraintes sur (1) la géométrie et la nature de la marge et du bassin, (2) l'évolution de la marge,suggérant une histoire multiphasée comprenant un stade de rifting et/ou d'accrétion océanique, suivi d'un épisode de déformation coulissante tardive liée à la migration du bloc Alboran vers l'ouest, et d'une reprise en compression distribuée du bassin profond au haut de la marge au Plio-Quaternaire; (3) les modalités de réactivation qui se traduisent par des chevauchements aveugles néoformés à pendages sud, notamment au pied du banc de Khayr-al-Din, suggérant un soulèvement du banc de 0,2 mm/an à 0,75 mm/an au Plio-Quaternaire et un début d'écaillage crustal
The inversion of passive margins appears to be one of the first steps towards the initiation of new subduction zones. This crucial step in plate tectonics nevertheless still raises many questions. The study of margins currently reactivated by compressional tectonics is thus essential to better understand this process. These margins are uncommon, located in different geodynamic settings, and the factors determining their evolution are poorly constrained. The Algerian margin, located in North Africa, is one of handful of modern examples worldwide. The evolution of this margin, rifted during the Miocene, in a back-arc setting, is part ofthe complex puzzle of the western Mediterranean. Since a few million years, the margin has suffered inversion and compression in the framework of slow on going convergence between the European and African plates. This convergence generates moderate to strong earthquakes in North Algeria. The relatively young age of the Algerian basin, the large sediment load, and the compressive forces, constitute favorable conditions to the formation of a future subduction zone. Studies from the past ten years indicate, that themain unresolved questions are related to (1) the deep structure of the Algerian basin and its southern margin (the type of margin, the nature of the basement, the dimension and nature of the ocean-continent transition, the style and the distribution of the compressional deformation), and (2) the history of the kinematic and geodynamic evolution of the basin. All of these unknowns have prevented a complete and thorough analysis of modalities of the Algerian margin inversion. This study focuses on the Central Algerian margin, in the area of Tipaza (West of Algiers), a key region to understand the mechanism of the opening of the Algerian basin. Processing and analysis of a deep wide-angle and multichannel seismic new data set acquired in the context of the French-Algerian project SPIRAL (Sismique profonde et Investigation Régionales en Algérie, 2009)have enabled us to determine the crustal structure of the Algerian basin and its southern continental margin,as well as the pseudo-3D structure of a specific feature in the study area: the submarine topographic highformed by the Khayr-al-Din bank. The analysis of the deep structure of the margin reveals features inherited from its complex evolution: (1) a crust of continental nature of more than 15 km thick at the upper margin(Khayr-al-Din Bank), (2) a thin crust of oceanic nature, 5-6 thick in the deep basin, including slightly high velocities at its base (7.2 km/s - 7.3 km/s), (3) similarities with margins formed in context of transform deformation, (4) a progressive deepening of the whole sedimentary cover and the thickening of the Plio-Quaternary sediments, from the distal deep basin towards the margin foot, coeval with (5) a long wavelengthflexuration of the basement in the basin. Results from this study provide new constraints on (1) the geometryand nature of the margin and the basin, (2) the evolution of the margin, suggesting a multiphased history including a stage of rifting and/or oceanic spreading, a transcurrent episode due to the westward migration of the Alboran block, and a diffuse Plio-Quaternary compressional reactivation distributed from the deep basinto the upper margin; (3) the mechanisms of the reactivation marked by newly formed south-dipping blind-thrusts, especially at the foot of the Khayr-al-Din bank, and suggesting a Plio-Quaternary uplift of the bankof 0.2 mm/y to 0.75 mm/y and the early stages of imbricate thrusting of crustal scales

Abstract:
La marge algérienne est un domaine complexe, bordé au sud par les zones internes des Maghrébides (AlKaPeCa) qui chevauchent les zones externes telliennes vers le sud. La partie offshore de ce système constitue un bassin d‘arrière arc où s‘est déposée une série sédimentaire mio-pliocène reposant sur un substratum de nature et d‘origine variables spatialement. L'objectif de ce travail a consisté à analyser et modéliser le fonctionnement des systèmes pétroliers et à quantifier les volumes d‘hydrocarbures accumulés. Avant de procéder aux différentes modélisations numériques, stratigraphiques et thermiques, un modèle géologique conceptuel a été élaboré sur la base des données de géologie de terrain et de sismiques. La continuité terre- mer du socle kabyle a permis une extrapolation stratigraphique entre des formations oligo-miocènes en affleurement et les unités acoustiques définies dans le bassin offshore. L‘analyse tectonique dans les deux domaines a abouti à une évolution en trois phases : (1) syn-rift où le bassin a été ouvert en transtension à partir de l‘Oligocène supérieur-Aquitanien, (2) phase post-rift durant laquelle il y a eu le développement des bassins intra-arcs, la collision AlKaPeCa- Afrique et le magmatisme, (3) phase d‘inversion où la marge devient active essentiellement à partir du Quaternaire. En définissant l‘ensemble des éléments des systèmes pétroliers avec des incertitudes variables, la simulation du fonctionnement de ces derniers par modélisation de bassin 2D/3D a montré des possibilités d‘accumulation d‘huile et de gaz majoritairement près de la marge, entre 20 et 65 km de la côte avec un maximum de portée de 70 km dans le golfe de Bejaia
The Algerian margin is a complex domain, limited to the south by the Maghrebian internal zones (AlKaPeCa) that overthrust the external Tellian zones southward. The offshore part of this system constitutes a back-arc basin, where a mio-pliocene sedimentary series were deposited over a substratum of laterally variable origin and nature. The goal of the present work consisted in analyzing and modelling the petroleum system at work and calculating hydrocarbon volumes. Before proceeding to different numerical basin, stratigraphic and thermal modelling, a conceptual geological model is required and was performed based on field geological studies and stratigraphic and structural interpretations of the seismic profiles. The extension of the continental crust beyond the foot of the margin, allows determining a chronostratigraphic model by extrapolation of the outcroping oligo-miocene formations onshore to the acoustic pre-messinian units defined in the offshore basin. Besides, a tectonic analysis in both onshore and offshore domains gave rise to three main steps of evolution: (1) syn-rift phase where the basin was opened by transtension since Late Oligocene- Aquitanian, (2) post-rift phase in which intra-arc basins were developed, AlKaPeCa and Africa docked and magmatism activity took place, (3) inversion phase where the margin became active mainly since Quaternary times. After defining the different petroleum system elements taking into account variable uncertainties, the 2D/3D petroleum system model depicts possibilities of oil and gas accumulations mainly close to the margin, between 20 to 65 km from the coastline to the north with a maximum range of 70 km in the Bejaia Gulf

Abstract:
The Collo Basin, a small coastal aquifer, consists of three different alluvial units characterized by different hydraulic properties. If adequately managed, alluvial unit No. 3, being the best aquifer, is capable to supply domestic water for the city of Collo in the short and the long run as well. The estimated rate of water withdrawal from unit No. 3 exceeds more or less that of direct recharge by precipitation, causing hence a lowering of the water table. Consequently, recent chemical analyses of water samples show that groundwater is, to some extent, further contaminated by sea water. Therfore, it is time for local authorities to take some legal measures prohibiting any additional well drillings in this area as to prevent a possible disaster until all hydrological parameters are identified with certain degree of accuracy.

Abstract:
Dans le bassin de l'ahnet, la productivite ne semble pas etre reliee a des variations lithologiques dans les reservoirs. Dans ces vastes structures de l'ahnet central, la presence de gaz a ete prouvee mais seuls quelques puits ont donne un debit raisonnable. Cette productivite aleatoire est probablement reliee a la distribution spatiale des fractures dans le reservoir. Pour verifier plusieurs hypotheses, nous avons utilise une approche combinant plusieurs concepts pour repondre a des problemes poses par le geologue principalement, le processus de deformation, la prediction des zones fracturees et la repartition spatiale de la fracturation a l'echelle du reservoir. Cette approche combine plusieurs methodes incluant la modelisation analogique, la modelisation numerique ainsi que la modelisation geometrique qui utilise le comportement fractal des familles de failles pour extrapoler a l'echelle du reservoir. La technique experimentale de modelisation analogique nous a permis de choisir un modele qui restitue au mieux le processus de deformation et l'initiation des failles majeures dans les structures de l'ahnet central. Les outils numeriques nous ont aide a repondre aux questions posees sur la formation des anticlinaux et a l'origine possible de la variation de la distribution des fractures naturelles. Les differents tests de modelisation geometrique nous ont permis de choisir un reseau de failles subsismiques le plus plausible et de distinguer les zones ou la repartition spatiale de ce type de failles est le plus dense. Les methodes d'analyse de la courbure nous ont permis de distinguer les zones a forte densite de courbure et leur repartition spatiale sur la structure. Des tests de simulations de l'ecoulement ont ete realisees apres simulation a trois dimensions du reseau de fractures le plus probable.

A cheval sur des domaines varies, le bassin-versant de l'oued tafna s'etend sur presque la moitie de l'oranie nord-occidentale et comprend deux ensembles structuraux: un ensemble atlasique au sud et un ensemble alpin au nord, ce dernier ayant connu en outre une activite volcanique importante, mio-plio-quaternaire.

Abstract:
Since the end of the Algerian decolonization war in 1962, French forces have been involved in many overseas operations, mostly in Africa, Afghanistan and the Middle East. From1991, French forces adjusted to a wide range of new operational challenges, while still applying the basic principles of combat and practising a reinforced interoperability at multinational, inter-agency, and joint levels. Heavily committed overseas, and infused with a specific expeditionary institutional culture, French military forces are positioned at the forefront of European and NATO forces. However, as the majority of the long-term plans for stability in Africa and in the Middle East are likely to require sustained military and security efforts, the cost of French actions is having a major impact on the national defence budget. In addition, the huge involvement of military forces on national soil (Operation ‘Sentinelle’) as a result of terrorist strikes in Paris could possibly limit the foreign interventions in the near future.

Abstract:
Muslim Women in French Cinema: Voices of Maghrebi Migrants in France is the first comprehensive study of cinematic representations of first-generation Muslim women from the Maghreb (Algeria, Morocco, Tunisia) in France. Situated at the intersection of post-colonial studies, gender studies, and film studies, this book uses the multi-layered concept of ‘voice’ as an analytical lens through which to examine a diverse corpus of over 60 documentaries, short films, téléfilms (made-for-television films), and feature films released in France between 1979 and 2014. In examining the ways in which the voices, experiences, and points of view of Maghrebi migrant women in France are represented and communicated through a selection of key films, this study offers new perspectives on Maghrebi migrant women in France. It shows that women of this generation, as they are represented in these films, are far more diverse and often more empowered than has generally been thought on the basis of the relatively narrow range of media and cultural productions that have so far reached mainstream audiences. The films examined in this study are part of larger contemporary debates and discussions relating to immigration, integration, and what it means to be French.

Abstract:
AbstractThis study aims to estimate the eroded and transported sediment yields from the The Hodna basin (26,000 km2) situated in central Algeria by two approaches. In the first model, the data of the gauged subbasins are extrapolated to the ungauged areas based on the homogeneity of factors that influence the water erosion-sediment transport process. In this approach, the specific eroded and transported sediment yield in the Hodna basin is estimated to be 425 t/km2/yr. In an alternative approach, the eroded yield is estimated by mapping erosion using the (RUSLE) in a GIS environment. The obtained results show a high eroded sediment yield of approximately 610 t/km2/yr.The observed difference between the results of the two approaches can be explained by the amount of sediment that is eroded but is not transported by runoff.These two methods show high eroded and transported sediment yield values in the Hodna basin region; these high yields may seriously threaten the central flat zone with progressive deposition.

Abstract:
Abstract The Cambro-Ordovician Hamra Quartzite Formation is one of the important reservoirs from Algerian Sahara. The objectives of this study were to characterize the wellbore breakouts and constrain the maximum horizontal stress (Shmax) based on the inferred compressive failures within the Paleozoic reservoir. A-Quality breakouts were deciphered within the reservoir interval from a cumulative of 138m of acoustic image log indicating a mean SHmax orientation of N118˚E±8˚. Interpreted breakout widths exhibit a range between 32.6˚ and 90.81˚, which indicated a SHmax range of 24.4-34.7 MPa/km. The average breakout width of 62.58˚ translates to a SHmax gradient range of 27.2 and 31.2 MPa/km. The relative magnitudes of the principal stresses indicate a strong strike-slip tectonic stress state with a SHmax/Shmin ratio of 1.41-1.81 within the Ordovician interval. Following the frictional faulting-based stress polygon approach, measurement of minimum horizontal stress (Shmin) from minifrac tests and observations of compressive failures from acoustic image log provided strong constraints on the SHmax magnitude in the studied Ordovician tight reservoir interval in the absence of core-measured rock strength.
