Himmich, Kenza. "Antarctic sea ice : a seasonal perspective". Electronic Thesis or Diss., Sorbonne université, 2024. http://www.theses.fr/2024SORUS105.
Texto completoAntarctic sea ice has undergone an abrupt reduction in 2016, following more than four decades of a slow increase. This could have wide-ranging consequences given the importance of Antarctic sea ice for climate, ocean, and local ecosystem. Yet, climate models fail to capture this observed evolution, leaving considerable uncertainty regarding its origin, impacts and future evolution. Models failure relates, but not only, to a poor understanding of fundamental Antarctic sea ice processes. In this thesis, we contribute to progress understanding of Antarctic sea ice, adopting a seasonal perspective. We investigate the drivers of seasonal sea ice edge advance and retreat, analyzing the roles of thermodynamic preconditioning, air-ice-sea heat fluxes and sea ice dynamics. We show that, in the mean state, timings of ice edge advance and retreat are largely controlled by thermodynamics, via preconditioning from mixed layer heat content and sea ice thickness, respectively. Variations in air-ice-sea heat fluxes and sea ice dynamics have a significant but secondary importance. This conclusion is supported by a simple thermodynamic model, observational analyses and the NEMO ice-ocean model. We also show that recent changes in sea ice seasonality are mainly driven by thermodynamics, similar to the mean state. The reduction in Antarctic sea ice following 2016 coincides with nearly circumpolar earlier retreat and later advance of the ice edge. Our analysis links these changes to thinner ice in winter, faster melt in spring and warmer upper ocean in summer, in line with ice-albedo feedback processes. Based on the circumpolar footprint of these changes, we argue that they likely have an oceanic origin
Boutin, Guillaume. "Interactions vagues-banquise en zones polaires". Thesis, Brest, 2018. http://www.theses.fr/2018BRES0050/document.
Texto completoSea ice, which covers most of the ocean near the poles, is a key component of the climate system. Global warming is driving its massive melting, especially in the Arctic. Where sea ice cover decreases, fetch increases leading to more energetic sea states. This means potentially enhanced wavesice interactions effects in the future. The quick evolution of sea ice extent and volume combined with the intensification of human activities in polar regions urge us to improve our understanding of waves-ice interactions.Sea ice attenuates waves. They can however propagate through it and break it far into the ice cover. Attenuation depends on ice properties such as floe size, thickness, etc. Once broken, resulting floes are more likely to drift and melt. In addition, wave attenuation yields a force which pushes the floes in the direction of wave propagation.A simplified representation of sea ice, including a floe size distribution, has been incorporated in a wave model.It allows us to show the important contribution of dissipative mechanisms in the wave attenuation, especially those induced by the bending of the ice plates. After validation, the modified wave model is coupled to an ice model. The floe size distribution is exchanged in the coupled framework and used in ice lateral melt computation. The force exerted by the waves on the ice floes is sent from the wave model and is shown to compact sea ice in summer. This reduces the melting and significantly increases the temperature and salinity in the surface ocean close to the ice edge
Mercadier, Thomas. "Retrait particulaire par étalement et retrait d’un film de résine". Electronic Thesis or Diss., Université Grenoble Alpes, 2023. http://www.theses.fr/2023GRALT095.
Texto completoEfficient particle contamination removal is crucial in maximizing yield within the microelectronics industry. However, conventional particle removal techniques may become impractical when dealing with complex and fragile surface structures, as their application can potentially cause physical damage. This challenge has led to the development of new cleaning processes based on innovative concepts, such as a resist film lift off approach. The resist film lift-off leads to the particle removal due to the particle surface bonded to the resist. One of these particle removal processes is studied in this manuscript. In this process, the resist film is composed of two immiscible organic polymers. The process consists of the resist spin-coating followed by a diluted ammonia dispense at room temperature. Thanks to the latter chemical step, one of the polymers is dissolved inducing the delamination and lift-off of the remaining polymer with drag and lift forces.This manuscript sheds light on the critical role of the organization of two immiscible polymers within the resist film in the context of film lift-off. The organization of these polymers was shown to depend on the substrate surface energy through Tof SIMS analysis. For instance, on a hydrophilic substrate, the soluble polymer exhibits a pronounced affinity for the interface. Such an organization on hydrophilic surface minimizes the interfacial area that needs to be delaminated during the resist removal step. Consequently, the effectiveness of ammonia-based film removal relies on the substrate’s surface energy and is only achievable if the substrate surface energy is below 66mN/m.This manuscript provides valuable insights into the modification of the polymers’ organization. The tuning of some parameters from the resist formulation as the blend ratio or the resist thickness and the addition of a bake after the coating are shown to modify this surface energy peeling limit. Additionally, a Particle Removal Efficiency study was conducted on blanket wafers to determine and understand how these three parameters influence cleaning efficiency. It has led to the optimization of process efficiency. This optimized process efficiency was evaluated on structured surfaces. The results showcased its capability to efficiently remove particles while preserving the integrity of delicate structures.This PhD project has contributed to broadening the comprehension of particle removal using a resist peeling process. Moreover, it has demonstrated the potential application of this method in an industrial context

Texto completoLarge weaknesses remain considering our understanding of the drivers of phytoplankton growth in Arctic sea ice zone, especially due to large uncertainties in the interactions between sea ice, light and phytoplankton.The aim of this PhD thesis is to better understand these interactions and to highlight the main uncertainties considering these interactions in Earth System Models. I first show that the ice-free period is mainly led by the solar irradiance cycle and by the ocean-atmosphere thermodynamic exchanges during summer. It is consequently projected to extend into fall in the future. Then, I evaluate the radiative transfer scheme in the ocean model NEMO, in arctic sea ice zone. I show that NEMO largely underestimates the transmitted shortwave radiation in ice-covered waters, especially due to the overestimation of the snow and the first level of the ocean attenuation. I finally define a diagnostic to describe available light seasonality in the sea ice zone and I study the impact of this diagnostic on simulated phytoplankton in the bio-geochemistry model PISCES. However, large uncertainties remain in the study of the relation between this diagnostic and the phytoplankton growth. This is especially due to the non-linearity between available light and phytoplankton growth and also due to the lake of knowledge about the phytoplankton physiology
Girard, Lucas. "Vers un nouveau cadre de modélisation rhéologique de la banquise". Phd thesis, Grenoble, 2010. http://www.theses.fr/2010GRENU021.
Texto completoIn this thesis, new approaches are used to model the mechanical behavior of sea ice and to evaluate sea ice models in terms of ice drift and deformation. It is first shown how the statistical and scaling properties of sea ice drift and deformation can be used as an evaluation metric for sea ice models. These properties are known to play an important role regarding ice growth estimates and should therefore be captured in sea ice models. The evaluation metric is applied to simulations performed with a coupled ocean/sea ice model, where the mechanical behavior of sea ice is represented using the Viscous-Plastic (VP) rheology, as in most current global ocean and climate models. The VP model is shown to be unable to capture the statistical and scaling properties of sea ice deformation. As these properties are a signature of the ice mechanical behavior, it suggests that the VP rheology is inappropriate for sea ice modeling. The new mechanical model developped during this thesis is based on the hyopthesis that sea ice deformation is mainly accommodated by fracturing and frictional sliding (brittle behavior) over a wide range of scales (stresses can be transmitted on long distances). The main characteristics of this new model, named the Elasto-Brittle (EB) rheology, are progressive damage to represent the brittle behavior, and an elastic constitutive law to allow long-range elastic interactions to take place. The EB rheology is first used to carry out a fundamental study of fracture in heterogeneous media. Simulations show that fracture is preceded by a divergence of the correlation length, measured from a correlation analysis of discrete events and from a scaling analysis of the continuous strain-rate field. The scaling properties of deformation that emerge in the vicinity of failure ressemble those observed for the brittle deformation of geophysical objects such as sea ice or the earth's crust. These results, that argue for a critical point interpretation of fracture, are discussed in the context of fracture at geophysical scales. Secondly, short term simulations of the winter Arctic sea ice cover are carried out using the EB rheology. The results show that the EB rheology captures well the statistical and scaling properties of sea ice deformation, motivating the implementation of the EB rheology in global sea ice models. On longer time scales, sea ice can recover its mechanical properties through refreezing of fractures. A healing law accounting for this process is presented along with preliminary results from simulations accounting for the effect of healing. Finally, a methodology for the implementation of the EB rheology within a global sea ice model is presented and discussed
Verin, Gauthier. "Propriétés physiques et optiques du manteau neigeux sur la banquise arctique". Thesis, Université Grenoble Alpes (ComUE), 2019. http://www.theses.fr/2019GREAU010/document.
Texto completoThe Arctic ocean shows a very strong seasonality trough the permanent presence of sea ice whose extent varies from 6 to 15 millions km2. As an interface, sea ice limits ocean - atmosphere interactions and impacts the global energy budget by reflecting most of the short-wave incoming radiations. The snow cover, at the surface, is a key element contributing to the optical properties of sea ice. Snow enhances further the surface albedo and thus delays the onset of the ice melt. In addition, snow is the main responsible for the vertical light extinction in sea ice. However, after the polar night, this low light transmitted to the water column is a limiting factor for primary production at the base of the oceanic food web. The snow cover, through the temporal evolution of its physical properties, plays a key role controlling the magnitude and the timing of the phytoplanktonic bloom. In the actual global warming context, sea ice undergoes radical changes including summer extent reduction, thinning and shifts in snow thickness, all of which already alter Arctic primary production on a regional and global scale.This PhD thesis aims to better constrain the snow cover contributions to the radiative transfer of sea ice and its impact on Arctic primary production. It is based on a dataset collected during two sampling campaigns on landfast sea ice. Physical properties of snow such as snow specific surface area (SSA) and density allow a precise modeling of the radiative transfer which is then validated by optical measurements including albedo, transmittance through sea ice and vertical profiles of irradiance in the snow.During the melt season, marine snow which shows strong spatial heterogeneity evolves fol- lowing four distinctive phases. The melting, which first appears at the surface and gradually propagates to the entire snowpack, is characterized by a decrease in SSA from 25-60 m2kg-1 to less than 3 m2kg-1 resulting in a decrease in albedo and an increase in sea ice transmittance. This is a chaotic period, where optical properties show a very strong temporal variability induced by alternative episodes of surface melting and snowfalls. The physical properties of snow are used in a radiative transfer model in order to calculate albedo, transmittance through sea ice and vertical profiles of irradiance at all depths. The comparison between these simulations and measured vertical profiles of irradiance in snow highlights the presence of snow absorbing impurities which were subsequently qualitatively and quantitatively studied. In average, impurities were composed of 660 ngg-1 of mineral dust and 10 ngg-1 of black carbon. They were responsible for a two-fold reduction in light transmitted through sea ice. The light extinction, calculated at all depths in sea ice, and represented by isolums, was compared to the temporal evolution of ice algae biomass. The results show that every significant growth in ice algae population is related to an increase of light in the ice. These growths were observed even at very low light intensities of 0.4 uEm-2s-2. Light variations in the ice were linked by snow metamorphism and snow melting at the surface
Balkowski, Tatiana. "Daniel Danis : une dramaturgie du retrait". Paris, EHESS, 2014. http://www.theses.fr/2014EHES0075.
Texto completoThis essay provides a thematic, structural and stylistic analysis of Daniel Danis' dramatic writings, with the main goal of defining the concept of withdrawal (retrait). A fundamental pattern and a foundation of the author's writing, the figure of withdrawal appears as an essential one, on the one hand because it lies at the basis of Daniel Danis' dramaturgie system, and on the other hand because it is related to the author's "fundamental concern" with the "Being". Seeing that withdrawal is the place and the form of the "Being", the phenomenology of withdrawal in Danis' work enables us to answerthe ontological question: "What is the Being?" Moreover, ontology being inseparable from the ontic, the figure of the withdrawal enables the author to consider the question of representation and, in doing so, to reflect on theater, which is the art of representing the absence. In relation with the different characteristics of the withdrawal in our body of texts, we will establish four types of withdrawal: withdrawal as a mark of absence; "with-drawal" as an attempt to demarcate, to draw a dividing line; withdrawal (retrait) as a repetition of the absence (in reference to the meaning of the prefix "re-" in French, as the mark of the repetition); withdrawal as a presence of the absence, or as a denoted and noted absence. Such a categorization will enable us to highlight all that is withdraw in Daniel Denis’ work (words, images, ideas, figures) and, more generally, to evidence the unfailing link between ontology and dramaturgy, between speech on the Being and speech of the being

Bergey, Bernadette. "Le retrait de l'associé du GAEC". Nantes, 1987. http://www.theses.fr/1987NANT4003.
Texto completoThe gaec, groupement agricole d'exploitation en commun, usually set up by the same family's members and mainly father and son, this in order to make the tool of work more profitable by a collective work and means of running, may disappear in case of departure of a partner. This kind of company intended to last only two generations, father's and son's. The partner's departure from the gaec may indeed creates two situations: - either the perennity of the gaec, if the departure is followed by the leaving partner's transfer of shares or free (of charge) if "disposition inter vivos" or a succession. However it is not without juridical or fiscal effect. - or its dissolution, if the impossibility of a partner's transfer of shares makes it impossible keeping the gaec in harmony with the law, or the statutes which control it. Out of the juridical distraints such a process creates, the dissolution is not neutral about the taxes and often requires important expenses. So, solutions will be found to try to minimize it or avoid this event
