The depositional styles of sediment gravity currents depend, in part, on the relationship of flow magnitude to the scale of topographically controlled containment and range from unconfined lobes to fully contained deposits. Determining the degree of containment is important for understanding depositional processes, land to ocean sediment transfer and subsurface reservoir characterization/prediction. Depositional models of the fully contained (commonly referred to as 'ponded') end member have been developed (e.g. fill-and-spill model). However, fully contained deposits represent only a portion of deepwater deposits and little work has been done identifying and examining the degree of containment of the more complex, partially contained deposits in outcrop. Here, I document the sedimentological facies and stratigraphic architecture of the Zorrillo Unit, a partially contained system exposed at Cerro Solitario within the Upper Cretaceous Tres Pasos Formation of the Magallanes Basin. The evolution of partial containment at this outcrop is expressed as: 1) bypass in the proximal zone and flow stripping in the distal zone, 2) backstepping and blanketing of the outcrop, followed by 3) renewed bypass. The partially contained system at Cerro Solitario deviates from the widely used fill-and-spill model due to subtle relief. This record of infilling provides insight into the overall evolution of the depositional system. Within the Magallanes Basin, the partially contained and linked depocenters along the Chingue Clinoform represent the dying breaths of the Cerro Toro axial conglomerate channel system as the canyon-fed point source collapsed and choked off the sediment routing system out to the distal basin. / Master of Science / Subaqueous sediment gravity flows are responsible for moving large quantities of sediment from off the continent to the oceanic abyssal plain and the resulting deposits serve as some of the largest hydrocarbon reservoirs in the world. These deposits vary in a number of ways depending on numerous variables, including containment. Containment is related to how the sediment gravity flows interact with the seafloor topography. Models have been created describing at one end of the spectrum sediment gravity flows that have been fully contained (i.e., the fill-and-spill model) where the flows are trapped and not able to escape the confining topography. The other end of the spectrum is where flows do not experience any containment (unconfined lobes). There is a lack of work done addressing the middle ground of partial containment of sediment gravity flows and their resulting deposits. The Zorrillo Unit crops out at Cerro Solitario within the Late Cretaceous Magallanes Basin in southern Chile and offers a perfect location to study partially contained deposits. The architecture (the structure of the rocks) and facies (the character of the rocks) were identified. By characterizing and understanding the processes that created the partially contained outcrop, this outcrop can now be used as an analog for other similar depositional systems. Oil and gas companies use these outcrop analogs to aid in reservoir prediction for comparable deposition systems in the subsurface. Regionally, the context of the Zorrillo Unit within the Magallanes Basin is ambiguous and by characterizing it, details are added to this part of the basin’s history.

Before the introduction of the Euro many observers had expected an increase of inflationary pressures due to a de-coordination-shock to national wage bargaining. However, if anything systematically happened after the introduction of the Euro wage restraint increased (Posen and Gould 2006). A possible explanation for this finding is that a system of pattern bargaining has emerged with Germany figuring as a "centre of gravity" for European wage bargains (Traxler et al. 2008, Traxler and Brandl 2009). This paper studies wage and nominal unit labour cost spill-overs for the EMU for a panel over 13 manufacturing sectors from 1992-2005 and quantifies the effects of different countries. It turns out that there are strong interdependencies across EMU-members with regard to nominal wage growth. Indeed, a leading role accrues to Germany whose wage developments are twice as influential as those of the next important countries. Remarkably, the strong interdependence of wage growth is not reflected with regard to unit labour costs. Here, only the development in a core group composed of Austria, France, Germany and the Netherlands, is bound to each other. The development of nominal unit labour costs in other countries is largely independent from each other and especially from this core group.

The vertical and horizontal distributions of Euphausiacea in the northern Gulf of Mexico, including the location of the Deepwater Horizon oil spill, were analyzed from 340 trawl samples collected between April-June, 2011. This study is the first comprehensive survey of euphausiid distributions from depths deeper than 1000 m in the Gulf of Mexico and included stratified sampling from five discrete depth ranges (0-200 m, 200-600 m, 600-1000 m, 1000-1200 m, and 1200-1500 m). In addition, this study encompasses the region heavily impacted by the Deepwater Horizon oil spill. Data presented here could potentially be used in ecosystem models investigating trophic effects of the spill because euphausiids are the preferred prey of a variety of higher trophic organisms. Lastly, these data represent the first quantification of euphausiid assemblages in this location after the Deepwater Horizon event and can serve as a basis of comparison against which to monitor recovery of the euphausiid assemblage after exposure to Deepwater Horizon hydrocarbons and dispersant in the water column.

Conteúdo: v. 1 Texto - v. 2 Mapas / Resumo: Este trabalho apresenta Mapas de Vulnerabilidade Ambiental ao Óleo simulando um vazamento de óleo no fundeadouro do Porto de Santos, próximo ao litoral de Praia Grande. Foram também elaboradas Cartas de Sensibilidade Ambiental ao Óleo (SAO) para o trecho do litoral paulista entre os municípios de Praia Grande e Cananéia. A metodologia utilizada para elaboração das Cartas SAO é baseada nas normas do Ministério do Meio Ambiente e para a elaboração dos Mapas de Vulnerabilidade foi utilizado o modelo SIMAP, desenvolvido pela empresa ASA, capaz de representar a mancha de óleo na superfície do mar, na linha de costa e na coluna d'água. A área apresenta trechos com intenso uso turístico, principalmente nos meses de verão e áreas com ambientes naturais preservados, com destaque à presença do sistema estuarino-lagunar de Cananéia-Iguape e Unidades de Conservação, que conferem à área grande importância ecológica. As Carta SAO foram geradas nas escalas tática (1:150.000) e operacional (1:50.000 e 1:25.000) e os Mapas de Vulnerabilidade foram gerados em escalas entre 1:100.000 e 1:750.000, de forma a abranger toda a área da mancha de óleo. Os resultados confirmam a necessidade de avançar na abordagem da sensibilidade da costa ao óleo, incorporando às cartas SAO informações sobre a probabilidade das áreas serem atingidas, estimativas do tempo de contato na costa e informações sobre a área da mancha que tem potencial tóxico à biota. / Abstract: This paper shows the Environmental Vulnerability Maps a simulated oil spill in the anchorage of the Santos port, close to Praia Grande shore. ESI Maps for the São Paulo shore between the municipalities of Praia Grande and Cananéia were also built. The methodology used to build ESI Maps is based on the Ministry of the Environment rules and for the construction of the Vulnerability charts used the SIMAP model, developed by the ASA. This is capable of modeling the oil spill on the surface of the sea, in the coast line and in the water column. The whole area shows intense tourist use, especially during the summer and areas with preserved natural environments include the presence of the estuarine-lagoon system of Cananéia-Iguape and Conservation Units that give the area great ecological importance. ESI Maps were generated in the tatic range (1:150.000) and operational (1:50.000 and 1:25.000) and the vulnerability maps were generated using 1:100.000 and 1:750.000 scales, to cover the entire area of oil stain. The results confirm the sensitivity of the coast to oil, use of the information above has been incorporated in the ESI Maps to estimate shore contact lead time and of the oil spill and this toxicity potential on the environment. / Orientador: Paulina Setti Riedel / Coorientador: João Carlos Carvalho Milanelli / Banca: Eduardo Ayres Yassuda / Banca: Gabriel Henrique da Silva / Banca: Gilberto José Garcia / Banca: Iris Regina Fernandes Poffo / Doutor

The revision of the CEN/TR 15522-2:2012 methodology contains new biomarkers to facilitate forensic fingerprinting of the variety of oil types that can be a part of different crimes and the purpose of this project is to validate the biomarkers of the new methodology. Biomarkers were validated by examining corresponding diagnostic ratios compatibility with the internationally used sampling cloth, discriminating power, correlation and simulated weathering sensibility through GC-SIM-MS analysis followed by statistical evaluation with t-tests, diagnostic power, Pearson correlation matrices and MS-PW plots respectively. Results based on most of the diagnostic ratios showed good compatibility with the internationally used sampling cloth, expected patterns of biodegradation and photo-oxidation except for observed photo-oxidation of hydro PAHs and that normative ratios and informative ratios with high diagnostic powers, but with strong correlations for some of the tested ratios, could be identified in diesel oils. Due to delimitations however such as the limited number of oils with similar origins that were analyzed the results should be regarded as guidelines that can be expanded.

Neste trabalho foi realizado um levantamento GPR 4D em laboratório no qual foi simulado o vazamento de óleo de uma ETD - Estação de Transmissão e Distribuição de Energia Elétrica. Os estudos consistiram em derramar 15 litros de óleo em três experimentos: tanque contendo areia seca, tanque contendo areia úmida mais gradiente hidráulico e tanque contendo areia úmida. Em todos os experimentos o objetivo foi detectar a pluma de contaminação e avaliar a migração desse óleo com o tempo. Os dados GPR 4D foram adquiridos utilizando-se uma antena blindada de 400 MHz modelo SIR-3000 equipamento da GSSI. O monitoramento no tempo de aquisição dos dados variou de 2 minutos até 12 dias. No experimento com o tanque preenchido com areia seca não foi possível determinar a pluma de contaminação devido ao baixo contraste entre as propriedades físicas do meio e a pluma contaminante. No experimento em que o tanque foi preenchido com areia úmida e havia a presença de um gradiente hidráulico, foi possível determinar a migração da pluma de contaminação a partir do 5º dia. Para finalizar, o 3º experimento onde o tanque estava cheio de areia úmida também não foi possível identificar a pluma, devido ao baixo contraste entre as propriedades físicas. Nesta pesquisa também foram realizadas modelagens numéricas 2D utilizando o método FDTD, onde foram simulados os três experimentos, considerando posições intermediárias da pluma de contaminação em função do tempo. Os resultados das modelagens foram concordantes com os resultados obtidos com dados reais e ajudaram a definir o padrão de reflexão da pluma contaminante. Os promissores resultados indicam que a determinação efetiva da pluma contaminante de óleo numa ETD é possível desde o meio que esteja saturado com água. Portanto, para garantir o sucesso das pesquisas GPR para fins de mapeamento e delineamento de plumas de contaminação em ETDs recomenda-se que a aquisição dos dados seja feita após um período de chuvas. / In this work a 4D GPR survey was accomplished in a laboratory in which a oil leak from a ETD Estação de Transmissão e Distribuição of electric energy was simulated. The studies consisted in an oil spill (15 liters) in three different experiments: i) tank containing dry sand, ii) tank containing wet sand with a hydraulic gradient and iii) tank containing wet sand. In all experiments the objective was detect the contamination plume and evaluate the migration of the oil with the time. The 4D GPR data was acquired using a shielded antenna of 400 MHz model SIR-3000 of the GSSI equipment. The time monitoring of the data acquisition ranged from 2 minutes up to 12 days. In the experiment-1 with the tank filled with dry sand wasnt possible to determine the plume contamination due to the low contrast of the physical properties between the environment and the plume. In the experiment-2 where the tank filled with the dry sand in the presence of a hydraulic gradient, was possible to determine the migration of the plume from the fifth day. Finally, the experiment-3 where the tank was filled with wet sand wasnt possible to identify the plume, due to the low contrast between the physical properties. This research also conducted 2D numerical modeling using the FDTD method, where the three experiments were simulated, considering intermediary positions of the contamination plume with respect with time. The results of the modeling were consistent with the results obtained with real data and helped to define a pattern of reflection of the contamination plume. The promising results indicate that the effective determination of the contaminating plume of oil in an ETD is possible provided that the environment be saturated with water. Therefore, to guarantee the success of researches with GPR for mapping and delineation of contamination plumes in ETDs its recommended that the data acquisition be realized in the rainy season.

En quarante ans, la Bretagne a subi en moyenne un naufrage de pétrolier tous les cinq ans. A chaque marée noire, le dommage écologique génère des mobilisations massives, des controverses sur la scène publique et la remise en cause des dispositifs de régulation. Malgré son évidence sensible, ni le régime international d'indemnisation (FIPOL) ni le Droit national n'intègrent l'atteinte environnementale comme motif supplémentaire de responsabilité financière pour les opérateurs. Les dommages de la pollution sont pris en compte à travers, d'un côté, les préjudices économiques et matériels et, de l'autre, les dommages purs à la biodiversité, sous la forme d'actions de restauration des milieux naturels. Les critiques pointent la faiblesse de la dissuasion : les coûts d'une marée noire pour les acteurs du transport maritime pétrolier sont considérés dérisoires au vu des profits et donc peu incitatifs à des comportements plus prudents. Elles réclament également la reconnaissance des dommages écologiques par le Droit, qui ouvrirait la possibilité de conséquences juridiques et économiques concrètes aux faits de pollutions et l'indemnisation des atteintes à l'environnement.Cette recherche s'intéresse aux processus de changement vers la reconnaissance des dommages écologiques des marées noires. Il ne s'agit pas de questionner l'efficacité de la prise en compte des dégradations environnementales par le dispositif de gestion ou les voies juridiques susceptibles de soutenir son intégration dans le Droit - déjà largement explorées - mais d'étudier les réalités du dommage écologique et d'analyser les actions de changement mises en oeuvre par des acteurs pour susciter leur reconnaissance. Cette analyse est conduite à partir de deux cas d'étude, la marée noire de l'Amoco Cadiz (1978) et celle de l'Erika (1999).Nous explorons une voie alternative et élargie de compréhension des atteintes de la marée noire, en considérant que la marée noire endommage aussi des relations plurielles entre hommes et environnement. Grâce à la sociologie pragmatique développée par Thévenot dans L'action au pluriel (2006) nous montrons les réalités plurielles du dommage écologique en termes d'attachements d’hommes à des non humains, que ni la description des écologues, ni celle des attachements de type marchand ne parviennent à saisir. Par ailleurs, à partir d'une analyse stratégique de la gestion de l'environnement (Mermet et al., 2005), nous étudions la manière dont les acteurs élaborent l'action de changement et comment celle-ci porte le dommage écologique. Nous nous intéressons tout particulièrement à la manière dont les enjeux de l'action induisent certains choix de qualification du dommage au tribunal.La recherche propose ainsi de nouvelles connaissances sur le dommage écologique, qui pourraient en renouveler la définition (intérêt théorique). Questionner les atteintes aux attachements pourrait également ouvrir une voie intéressante pour soutenir de nouvelles formes de justification sur la scène publique et favoriser la reconnaissance juridique des dommages écologiques (intérêt opérationnel). Enfin, elle articule deux cadres de pensée jusque-là disjoints en sciences humaines et qui se révèlent complémentaires. En donnant à voir les réalités plurielles, individuelles et collectives, des dynamiques environnementales, cette recherche propose d'enrichir la compréhension de la mise en oeuvre d'une action de changement au-delà des analyses de l'action collective (Cefaï, 2007). / Over the last forty years, an oil tanker has sunk off the Brittany coast of France every five years on average. Each time, the ecological damage from the oil slick has mobilised huge numbers of people to volunteer and demonstrate, and generated public controversy and criticism of regulatory procedures. Although oil spills provoke evident impacts, neither the International Oil Pollution Compensation Funds (IOPC Funds) nor French Law recognise environmental detriment as a motif for financial compensation by the operators. The damages and pollution are taken into account firstly as economic and material losses, and secondly in terms of damage to biodiversity requiring habitat restoration actions. Critics highlight the feeble deterrent and the lack of incentive for maritime oil transporters to reduce risks: in relation to their profits the costs of an oil slick to them is regarded as derisory. These critics also call for recognition of ecological damages by the law. This would allow environmental pollution to incur economic and juridical responsibilities, and for environmental harm to require compensation.This research project looks at change processes leading to the recognition of ecological damage from oil slicks. We do not add to the existing substantial debate over the efficiency or interest of integrating environmental concerns into conduct rules and the legal system, nor evaluate different methods for doing do. Instead we study the realities of ecological damage, and analyse actions for change implemented by different actors to provoke their recognition. This analysis is based on two case studies: the oil slicks from the Amoco Cadiz (1978) and the Erika (1999).We explore an alternative and wider approach to understanding the harm caused by an oil slick, by considering that it damages multiple relationships between man and the environment. Using the concept of pragmatic sociology (Thévenot, “L’action au pluriel”, 2006) we reveal the multiple realities of ecological damage in terms of the relations between humans and nonhumans. These relations cannot be described in purely commercial nor ecological terms. Using a strategic analysis of environmental management (Mermet et al., 2005), we study how actors elaborate an action for change and how the action represents environmental damage. We look particularly at how the challenge of the action leads to certain choices when qualifying the damage to the courts.Thus, the study proposes new information on ecological damage, allowing the definition to be renewed (theoretical interest). By examining ecological damage in terms of harm to human – nonhuman relations, it provides an interesting support for new forms of justification in the public arena, and promotes legal recognition of ecological damage (operational interest). Finally, the study brings together, and shows to be complementary, two conceptual frameworks hereto unarticulated in human sciences. The study reveals the multiple individual and collective realities of environmental dynamics, and thus allows a richer understanding of the implementation of an action for change than a standard analysis of collective action (Cefai, 2007).

O presente trabalho concentrou os esforços no desenvolvimento de um modelo lagrangiano de trajetória de partículas que simule o movimento de manchas de óleo em ambiente marinho. O modelo utilizado é o Modelo Lagrangiano de Partículas com Deslocamento Aleatório (MLPDA), que é baseado na equação de Langevin. Em princípio, o algoritmo da advecção da mancha de óleo devido ao vento é implementado no MLPDA, visto sua importância ao deslocamento das partículas. É considerado que 3% da velocidade do vento a 10 metros de altura permite uma boa representação da deriva de manchas de óleo em ambiente marinho. Os testes para este algoritmo apresentaram resultados satisfatórios. Posteriormente, é implementado um algoritmo que representa o processo físico de espalhamento do óleo, conhecido também por espalhamento mecânico, que é definido como o movimento horizontal devido às forças gravitacionais, viscosas e inerciais. No presente estudo, esse processo é fundamentando nas equações definidas por Lehr et al. (1984), onde os resultados dos testes mostraram que as partículas espalham conforme exposto por esse mesmo autor e são influenciadas até cerca de 100 h de simulação. Ainda neste estudo, é avaliado o módulo de cálculo de área implementado no MLPDA. É advertido que malhas grosseiras podem resultar em áreas superestimadas, sendo aconselhável o uso de malhas mais refinadas para o cálculo dessas áreas. Por fim, três cenários de simulação de um derrame hipotético de óleo na Baía do Espírito Santo, no interior do Porto de Tubarão, são conduzidos para ilustrar uma aplicação do modelo desenvolvido. As simulações expõem que há grandes diferenças entre os resultados obtidos, principalmente entre o cenário que desconsidera o vento e os outros dois com a consideração desta forçante. O primeiro cenário, as partículas tenderam a permanecer na Baía do Espírito Santo, enquanto para os demais cenários as partículas caminharam para os canais do sistema estuarino da Grande Vitória (Canal da Passagem e Canal de Acesso aos Portos). / The computational modeling is an important tool to predict the trajectory and fate of the slick oil in different environmental conditions, since the complexity of processes involving oil spill. Thus, the present study has concentrated efforts on developing of a particle tracking lagrangian model that simulate the oil slick movement in the marine environment. The model used is Lagrangian Particles Random Walk Model (MLPDA), that it is based on the Langevin equation. First, the algorithm of the advection of the oil slick due to wind is implemented in the Random Walk Particle Lagrangian Model (MLPDA), seen its importance to the displacement of particles. It is considered that 3% of the wind velocity at 10 meters height allows a good representation of the drift of the slicks. The tests for this algorithm presented satisfactory results. Posteriorly, is implemented an algorithm that represents the physical process of spreading, also known as mechanic spreading, that is defined as the horizontal movement due to gravitational, viscous and inertial forces. In the present study, this process is based on the equations defined by Lehr et al. (1984), where the results of the tests showed that the particles spread as shown by this author and they are influenced up to 100 hours of simulation. In addition, it is evaluate the module for calculation the area implemented in MLPDA. It is adverted that very coarse grid may result in overrated areas, being advisable to use fine grid for calculation of these areas. Finally, three scenarios of simulation of a hypothetic oil spill at the Espírito Santo Bay, in the Tubarão Port, are conducted to illustrate an application of the model development. The simulations show large differences among the results obtained, mainly among the scenario that neglect the wind and the other two with the consideration of this forcing. The first scenario, the particles tended to remain at the Espírito Santo Bay, while other scenarios the particles walked to the channels of the Great Vitória estuarine system (Passage Channel and Access Channel to Ports).

Petit Etat du Proche-Orient, situé entre la Syrie et Israël, le Liban, 10 452 km2, s’étend sur 225 km de côtes méditerranéennes et s’élargit jusqu’à 50 kilomètres à l’intérieur des terres. Sa diversité religieuse et culturelle est forte de 17 ou 18 communautés qui cohabitent bon gré mal gré. Ancrée et exprimée dans un contexte géographique de contrastes et de morcellement, cette pluralité religieuse et culturelle a connu une histoire contemporaine particulièrement sanglante. Le système politique confessionnel mis en place à la naissance du pays a interdit la construction d’une identité libanaise au bénéfice tout relatif d’un communautarisme primaire. Alors que la plupart des messages politiques ont échoué à proposer un projet sociétal commun, nous posons l’hypothèse que l’environnement durable offrirait l’embryon d’un contrat social autour duquel pourraient se regrouper les communautés. Durant l’été 2006, à la suite des bombardements de la station d’électricité deJiyeh au Sud Liban, une marée noire toucha la plupart des régions, chrétiennes et musulmanes. La pollution et la dégradation de l’environnement, longtemps restées de l’ordre du virtuel, acquièrent dès lors une dimension concrète. D’autres dégradations, récurrentes dans la vie quotidienne des Libanais, sévissent depuis de nombreuses décennies :l’accumulation des déchets, la déforestation, la pollution de l’air et de l’eau n’épargnent aucune région, aucune communauté. Alors même que la mémoire de l’histoire et la politique divisent les Libanais, ces communautés qui ont échoué jusqu’à présent à édifier une nation seraient-elles capables de préserver un territoire en voie de détérioration ? La mémoire géographique collective pourrait être un moteur de construction d’un présent autour du développement durable. La jeune génération, au centre de la problématique de cette thèse du fait qu’elle participe à la recherche de ce tronc écologique commun, est enquêtée par un questionnaire, soumis à 1 434 élèves d’écoles publiques et privées, L’objectif est de mesurer son degré de sensibilisation aux questions de l’environnement et de la pollution de cet environnement, puis de proposer un programme d’éducation qui prenne en compte les indicateurs psychologiques, sources et référents essentiels pour tout programme éducatif dédié à la sensibilisation à l’environnement. Les résultats du traitement des données d’une part, le projet applicatif de village écologique type, entamé en parallèle de cette recherche d’autre part, ont validé notre hypothèse de départ et les conclusions de ce travail estompent l’utopie qui pouvait se rattacher à une telle hypothèse. Le territoire est un ! / Lebanon is a Small country situated between Syria and Israel, it’s surface of 10 452km2 with 225 km of Mediterranean coastline and an average of 50 km of width inland. It is acountry of cultural and religious diversity with 18 religious communities fated to coexisttogether in a geographical environment that is as diverse and full of contrast. Its contemporaryhistory has been particularly violent with a fifteen year civil war dominating the country’simage and reputation. The confessional political system based on power-sharing between thecommunities institutionalised the sectarian divisions and prevented the emergence of aLebanese national identity. While most party political programmes emphasise the separateidentities and fails to suggest a common social project, we propose that an issue likesustainable environment could be the basis of a social contract, which will federate and bringtogether the interests of the various communities. Environmental pollution and degradationbecame a concrete reality in the summer of 2006, after the Israeli bombardment of the powerplant at Jiyeh in south Lebanon. The Oil Spill resulting from that spread all over the regionand did not spare any community. While history memory and politics divide the Lebanesealong communal lines, will these communities who failed to build a nation be capable to savea deteriorated environment? This common Geographical collective memory and the instinct topreserve it could be the engine to build a future based on sustainable development. The newgeneration is at the centre of this research. Analysis of the results of the 1434 questionnairesdistributed to primary students in both public and private school is the tool to measure thesensitivity of the young generation towards the issues of environment and pollution. One ofthe objectives of this study is to develop and implement an awareness raising program ofenvironmental education in schools. The program would be elaborated taking intoconsideration key psychological indicators. The results of the survey and the ecologicalvillage project which was started in parallel with the thesis have validated the hypothesis andthe findings of this work. In spite of the Utopian charachter of the hypothesis it is clearlydemonstrated here that while the people are many, the territory is one!
