Dans le système climatique global, l’océan Atlantique Nord est considéré comme une région très sensible qui joue un rôle crucial pour la dynamique de l’hémisphère nord via la circulation méridienne de retournement de l'océan Atlantique (AMOC), dont fait partie le système de front/courant des Açores. La thèse a pour but d’analyser les interactions hydrographiques et climatiques complexes dans la région des Açores, pour le Pléistocène moyen­‐Holocène, par l’analyse des foraminifères planctoniques de deux carottes prélevées en 2013 (Oceanograflu 2013), dans le segment OH1 de la ride médio-atlantique. La thèse est structurée en trois chapitres/articles qui présentent les principaux résultats et leur interprétation. Le premier article a pour but d’établir le modèle d’âge le plus précis possible et de tracer l’histoire de la production/préservation des carbonates dans la région des Açores, au cours du dernier cycle glaciaire. Pour ce faire, les valeurs de carbonate et δ18OG.ruber des deux carottes ont été analysées à haute résolution. Par ailleurs, l’application de la «Modern Analog Technique» à l’analyse des assemblages des foraminifères planctoniques a permis d’estimer les variations de température des eaux de surface (SST-mat). Les courbes d’abondance des espèces résistantes et sensibles à la dissolution ont permis de mettre en évidence d’éventuels intervalles de plus forte dissolution. La partie supérieure de chaque carotte a été datée par spectrométrie de masse (AMS)14C sur les tests de foraminifères. Le modèle d’âge adopté se base également sur la corrélation entre les courbes de δ18OG.ruber et l’enregistrement haute résolution du δ18OG.bulloides de la carotte MD95-2042 (Shackleton et al. 2000) de la marge ibérique, récemment recalibrée en utilisant les données synthétiques LS16 de δ18O (Lisiecki and Stern 2016) relatives aux foraminifères benthiques. L’analyse spectrale a permis de démontrer que les oscillations des valeurs de carbonate et du δ18OG.ruber, lors des derniers 144ka, sont contrôlées par un forçage climatique (orbital et sub-orbital) dans la région des Açores. La comparaison des courbes de carbonate et celles des espèces résistantes à la dissolution, pour les deux carottes situées à des profondeurs différentes, a permis de montrer les variations verticales de la lysocline de la calcite, en particulier lors des évènements de refroidissement plus extrêmes, par exemple à 22,1 kyr avec une remontée de la lysocline de 1000m environ. Le deuxième article essaie de reconstituer la variabilité complexe de l’hydrographie et de la paléoproductivité de l’Atlantique centre Nord lors des derniers 144 kyr grâce à l’analyse des assemblages des foraminifères planctoniques combinée à celle des variations de la température des eaux de surface (SST­‐mat). Les fluctuations d’abondance d’espèces actuellement caractéristiques de masses d’eau et/ou des systèmes de front/courant dans l’Atlantique Nord ont été utilisées comme traceurs paléocéanographiques. Cette approche a permis d’évaluer la migration latitudinale/longitudinale du système de front/courant des Açores durant le Quaternaire récent ainsi que celle d’autres fronts et/ou courants caractéristiques de l’Atlantique centre Nord. Le troisième article se focalise sur la variabilité du groupe G. ruber gr. dans la région des Açores. G. ruber a été considéré comme un plexus regroupant plusieurs autres espèces et sous espèces. Plus récemment, des études moléculaires et géochimiques mis en évidence la présence de plusieurs génotypes au sein du plexus G. ruber, ce qui implique l’existence de plusieurs (sous­‐) espèces avec des modes de calcification et des préférences écologiques différentes. Malgré l’abondante littérature récente sur ce sujet, les liens entre ces différents génotypes, variants morphologiques, préférences écologiques, et modes de calcification ne sont pas encore très bien compris. (...) / In the global climatic system, the North Atlantic Ocean is considered as a highly sensitive region, which plays a crucial role in the Northern Hemisphere dynamics through the so­‐called Atlantic Meridional Overturning Circulation (AMOC) system, of which the Azores Front/Current System represents an important part. The main aim of the thesis is to reconstruct the complex hydrographic and climatic interactions in such a climatically­‐sensitive area during middle Pleistocene to Holocene through the analysis of the planktonic foraminifera from two cores collected in the OH1 segment of the Mid‐Atlantic Ridge (MAR) south‐westward of the Azores archipelago during the Oceanograflu 2013 cruise. The manuscript is structured in three chapters presenting the major results and their interpretation (...)

Diz-se que há uma grande influência açoriana no litoral catarinense. Muitos trabalhos são realizados para estudar esse tema, porém, poucos analisam esse fato do ponto de vista lingüístico, principalmente em seus aspectos fonéticos e morfossintáticos. As poucas pesquisas realizadas estão voltadas para características muito gerais da fala catarinense ou se concentram na região de Florianópolis, atual capital do Estado. A escassez de material indica que pouco se conhece sobre a dita influência açoriana. O presente trabalho propõe investigar a fala de duas das três regiões mais antigas de Santa Catarina, cuja base de colonização foi açoriana: a antiga região de Itapocorói (que atualmente compreende a área dos municípios de Penha, Balneário de Piçarras e uma pequena parte do sul de Barra Velha) e o povoado de Nossa Senhora das Graaças do Rio São Francisco (hoje São Francisco do Sul). Para isto, foi preciso realizar duas pesquisas lingüísticas de campo, uma na região de Itapocorói e outra em São Francisco do Sul, com a finalidade de descrever as variantes atuais locais e verificar possíveis transformações fonéticas, lexicais e morfossintáticas em um grupo de sessenta informantes divididos em três faixas etárias distintas (trinta de cada localidade pesquisada). Foram utilizados dados colhidos em trabalho de campo por meio de: (a) locução espontânea; (b) aplicação de questionário lingüístico com 49 perguntas; (c) questionário valorativo com 6 perguntas. As características apontadas serão aquelas que, de maneira geral, diferenciem a variante local de outras variantes do Português do Brasil. Acreditamos que, com isto, seja possível conhecer um pouco mais a variante açoriana catarinense e sua história. / It is said that there is a great influence of Azores in the Santa Catarina coastline. Many works are carried out to study this subject, however, a few analysis this fact from the linguistics point of view mainly in their morphosyntactical and phonetics aspects. The few researches carried out are turned towards a lot of general characteristics of Santa Catarina speech or they centralize in Florianópolis region, present capital of the state. The lack of materials shows that not much is known about the related influence of Azores. The present work suggests investigating the speech of the three more ancient regions of Santa Catarina, whose colonization basis was from Azores: the ancient region of Itapocorói (that nowadays includes the cities areas of Penha, Piçarras and a small part of the south of Barra Velha) and the village of Nossa Senhora das Graças of Rio São Francisco (nowadays São Francisco do Sul). That is why, it was necessary to carry out two linguistics field searches, one in Itapocorói region and the other in São Franciso do Sul, with the purpose of describing the present local variant and the possible phonetics, lexical and morphosyntactical variants transformation in a group of sixty informers divided in three different age groups (thirty of each places researched). It was made use of data gathered work field through: a) spontaneous idiomatic expression; b) linguistic questionnaire application with 49 questions and c) valorables questionnaire with six questions. The characteristics showed will be the ones that, in general differ the local variant and the other variants of Portuguese from Brazil. We believe that, with this, it will be possible to know a bit more the variant from Azores of Santa Catarina and its story.

Tourism represents 10.3% of the global GDP. Moving abroad for holidays has never been simpler and cheaper. Destinations answer tourist's demands, they build more hotel complex, create new fun activities, provide more resources. This way of life seems paradisiac for visitors; however it does not look that good for local communities. Often left aside by capitalist corporations, their resources and environment are depleting, crowds of visitors invade their space and unsustainability is deeply rooted. The result is the installation of more inequalities and gap between social classes. An alternative to this Pandora's box was created about 50 years ago, although it only started to develop recently, claiming it is the solution to most of our environmental tourism issues: ecotourism. If you look for this type of holidays, you will find the Azores. Eight award winner as a green destination. It was decided this research would focus on its biggest island: Sao Miguel. One will investigate what is the reality behind the green curtain. To do so, the learning of local stakeholders towards ecotourism and how it affects their current actions and their sight for the future of the island's tourism will be explored.

L’archipel des Açores dans l’océan Atlantique est édifiées sur un épais plateau océanique, à proximité de la jonction triple entre les plaques Nord-américaine (Na), Nubienne (Nu) et Eurasienne (Eu). La formation du plateau et l’origine du volcanisme ont été le plus souvent attribués à la présence d’une instabilité mantellique. Cependant, la répartition et la morphologie des édifices volcaniques semblent avoir été grandement influencés par la déformation régionale liée à la migration de la frontière de plaque (Eu/Nu). En effet, la frontière serait passée d’une faille transformante aujourd’hui inactive, la zone de fracture est des Açores (EAFZ), à un rift ultra lent actif appelé le Rift de Terceira (TR).Lors de ce travail, nous utilisons le volcanisme comme marqueur de la déformation régionale. Nous nous intéressons particulièrement aux îles de S. Miguel et Graciosa, qui sont localisées à l’intérieur du TR, et à Santa Maria, une île volcanique éteinte qui se situe entre la EAFZ et le TR. De par leur position, ces trois îles constituent donc des cibles particulièrement appropriées afin d’étudier l’architecture et l’évolution de la frontière de plaque Eu/Nu durant les dernier Millions d’années. A partir de nouvelles données géomorphologiques, stratigraphiques, géochronologiques et tectoniques, couplées aux données bathymétriques et géophysiques disponibles, nous reconstruisons les étapes successives de construction et de démantèlement de ces îles puis discutons de leur signification géodynamique. Ces données sont ensuite complétées par des expériences de mécanique des fluides afin d’investiguer les liens possibles entre un panache mantellique, la migration de la frontière de plaque sur plusieurs échelles d’espace et de temps.Les résultats montrent que les édifices localisés dans le TR se construisent via des pulses volcaniques courts (<100 kyr) et relativement synchrones, séparés par des épisodes d’effondrements catastrophiques. Nous proposons qu’une telle évolution reflète des épisodes brefs et intenses de déformation régionale le long de la frontière de plaque active. La distribution des marqueurs tectoniques ainsi que leurs orientations N110 et N150 dans la partie Est de S. Miguel, nous conduit à proposer que l’extension oblique du TR est principalement accommodée par les failles bordières majeures du rift. Nous identifions une nouvelle tendance tectonique orientée N50° qui pourrait représenter des failles transformantes accommodant les variations d’obliquité du TR. L’activité de île de Santa Maria est ici datée entre 5.7 et 2.8 Ma. S. Maria a été façonnée par plusieurs effondrements sectoriels catastrophiques, le plus probablement déclenchés par les mouvements tectoniques régionaux. Nous identifions également une nouvelle structure de type graben reliant les îles de S. Maria et S. Jorge plus loin au NW. La forme de ce graben est semblable au TR et est située entre l’ancienne et la nouvelle frontière Eu/Nu. Nous interprétons ce graben comme un ancien rift transitionnel et donc comme une ancienne frontière de plaque Eu/Nu. A partir de nos données géochronologiques, nous proposons que la partie Est de ce rift transitionnel aurait migré vers la partie Est du TR entre 2.8 et 1.7 Ma.La migration de la frontière Eu/Nu a été interprétées par Vogt and Jung (2004) comme résultant de sauts successifs vers le NE de l’axe du Rift afin de maintenir sa position au dessus d’un point chaud fixe. Nos expériences de mécanique des fluides suggèrent que l’archipel des Açores, comme celui des Canaries, du Cap Vert, de Madère ainsi que les volcans sous marins de Great Meteor sont la signature en surface d’un groupe d’instabilités mantellique prenant naissance et remontant à partir du sommet d’un dôme thermochimique situé dans le manteau inférieur. De plus, Ces panaches secondaires pourraient être suffisamment faibles pour adapter leurs mouvements aux équilibres de forces pré-existants, notamment la structure et la morphologie de la lithosphère. / The Azores archipelago in the Atlantic comprises nine volcanic islands which developed on a thick oceanic plateau close to the Triple Junction between the North American (Na), the Nubian (Nu), and the Eurasian (Eu) lithospheric plates. The formation of the plateau and the origin of the volcanism remain controversial, but have been generally attributed to a plume-like mantle instability. However, the distribution of the volcanic edifices east of the Mid-Atlantic Ridge (MAR) appears greatly influenced by regional deformation associated with the northward migration of the Eu/Nu plate boundary from an extinct old transform fault, the East Azores Fracture Zone (EAFZ), up to the presently active ultra-slow Terceira Rift (TR). In this thesis, we use the volcanism as a marker for regional deformation. We especially focus on S. Miguel and Graciosa, which are located within the TR, and on S. Maria, an old volcanically extinct island located between the EAFZ and the TR. These three islands thus constitute particularly suitable targets to track the architecture and the evolution of the Eu/Nu plate boundary during the last few Myr. From new geomorphological, stratigraphic, geochronologic, structural/tectonic data, and existing bathymetric and geophysical data, we reconstruct the successive stages of growth and destruction of the islands, and discuss their geodynamic meaning. These data are then complemented by fluid dynamic modelling using laboratory experiments to examine the possible links between mantle instability, plate boundary migration and the development of the volcanism on various spatial and temporal scales.The new results on the islands show that the edifices located within the TR grew through short (<100 kyr) and partly synchronous volcanic pulses, separated by catastrophic sector collapses. We propose that such evolution reflects brief and intense episodes of regional deformation along the still active Eu/Nu plate boundary. The distribution of tectonic markers and the recognition of N110 and N150 tectonic structures in eastern S. Miguel leads us to propose that oblique extension in the TR is mainly accommodated by the master faults of the rift, and that the TR is presently not the locus of appreciable sea-floor spreading. Furthermore, we identify a new N050 trend, which may represent transform faults accommodating the variation in obliquity of the TR. The activity of S. Maria is here dated between 5.7 and 2.8 Ma. Like the recent islands, S. Maria experienced catastrophic flank collapses, most probably triggered by regional tectonics. We identify a new graben structure linking Santa Maria to the island of S. Jorge further NW. The shape of this graben is similar to the TR and it is located between the EAFZ and the current plate boundary. We interpret this graben as a former transient rift, and therefore an old Eu/Nu plate boundary. From the new data, we propose that the eastern part of the transient rift migrated to the eastern part of the TR between 2.8 Ma and 1.7 Ma.The overall migration of the Eu/Nu plate boundary to the north and the creation of the Azores plateau has been interpreted by Vogt and Jung (2004) as resulting from successive NE jumps of the rift axis to maintain its position over a fixed ‘hotspot’. Our fluid mechanics experiments suggest that the Azores, as Canary, Cape Verde, Madeira Islands and Great Meteor seamounts might be the surface signature of a cluster of mantle instabilities rising from the top of a large thermochemical dome located in the lower mantle. However, such secondary plumes present a strong time-dependence 5-40 Myr time scale. Moreover, they could be sufficiently weak to adapt their motions to the pre-existing force balances and morphology of the lithosphere. We therefore present a scenario of the Azores area evolution combining a triple junction and decompression melting buoyant material (i.e. such in volatiles and/or temperature) under a thickening lithosphere.

A dialogue with the memories of emigration and immigration indicated the political, economical and social situation of the Azores in the period preceding those movements and gave away the reasons to why they took place. What was recovered indicates that the Holy Spirit Feast had an important catalyst role in the formation of immigrant communities established at Vila Carrão. The symbols and meanings of this feast are perceived to this day as one of the most important elements of the Azorean s immaterial culture, and have been shared by generations to the present time. This group s approach was to investigate an assembling of immigrants from their departure in the Azores, including means of transportations, relationships established prior and during the journey in terms of labor and family and finally the living conditions found in the booming city that was Sao Paulo. The dichotomy of supply versus demand and the search for people to work the factories, industries and trade, which promoted the process, is also analyzed here. The experiences in the city that welcomed them and several other elements coalesced help translate their life s trajectories, as they organized themselves in the district, how they were dispersed in Brazil and around the world, and especially how was the initiative of reestablishing ties with countrymen and building the House of the Azores, which led to the reinvention of traditions and the reformulation of the Holy Spirit Feast. By unveiling these social experiments, the reinterpretations translated a new profane-religious cultural tradition in a diverse environment that is the metropolis formed by a true mosaic of cultures / Esta investigação aborda as trajetórias dos imigrantes açorianos na cidade de São Paulo no período de 1950 a 1960, tentando recuperar processos de formação, transformação e ressignificação das representações culturais. Ao estabelecer o diálogo com as memórias da e/imigração, essas experiências indicaram as situações políticas, econômicas e sociais dos Açores compreendidas no período anterior ao recorte cronológico estabelecido, que influenciaram as motivações do processo emigratório. Diante dessas trajetórias, teve a Festa do Divino Espírito Santo um papel relevante enquanto evento catalisador da formação da comunidade dos emigrantes estabelecidos na Vila Carrão. Ao abordar a festa nos Açores, tecendo sua história, seus significados e simbologias ainda percebidos na contemporaneidade, verifica que se trata de um dos mais relevantes elementos da cultura imaterial açoriana, no qual se observam modismos, gerações e sensibilidades temporalmente. Diante do enfoque desse grupo de imigrantes, investiga-se o processo desde a saída dos Açores, compreendendo como vieram, quais as relações já estabelecidas no que tange às questões de trabalho, redes sociais e familiares e em quais condições de vida se reconstruíram numa cidade em franco crescimento. São Paulo, nessa dicotomia oferta versus demanda, buscava na mão de obra imigrante o trabalhado nas fábricas, indústrias e comércio, fomentando o processo. Frente a essas experiências na cidade que os acolhia, aglutinaram-se elementos capazes de traduzir suas trajetórias de vida, como se organizaram no bairro, como se dispersaram no Brasil e no mundo e principalmente como se deu a iniciativa de restabelecimento dos laços conterrâneos na reconstrução do grupo a partir da fundação da Casa dos Açores, que traduziu na reinvenção das tradições a reformulação da Festa do Divino Espírito Santo. Ao descortinar essas experiências sociais, as ressignificações foram traduzindo uma nova tradição cultural profanoreligiosa num ambiente múltiplo que é a metrópole, formadora de um verdadeiro mosaico de culturas

The objectives of this study are to critically map and analyse past and current  discussions, negotiations and social processes that take place and relate to conditions created by living in- or monitoring the World Heritage City Angra do Heroísmo in the Azores, Portugal. Based on ethnographic fieldwork and qualitative interviews with the stakeholders in the city, the purpose has been to study how, and with what result and consequences, contested values, interests, rhetoric and powers are mobilized and made into dynamic forces for these stakeholders. Hence, this thesis gives a chronological presentation of selected issues and discussions, which have been taking place in the city from 1980 to 2012. The first subjects attended to are the 1980 earthquake and the nomination process which led to the inscription of Angra to the World Heritage List in 1983. However, some of the core objectives relate to the implications of living in a World Heritage City, given the preservation provisions which follow such a classified area. The aim has further been to assess the point of departure for the official monitors and their views on monitoring a vibrant historical area. The discussions analysed relate to the predicaments occurring when modern development is set up against preservation. However, the analyses show how policies and preservation ideals change, as well as how powers and authorities are challenged and affected by forces within and outside the “authorized heritage discourse”. Finally, this study has assessed the notions of pride, local attachment and identity among the inhabitants in Angra. The World Heritage Status can trigger a double sense of feelings; on the one side it holds emotions related to pride and recognition, on the other it represents obstacles for living- and developing the city in accordance with the present needs. World Heritage and tourism are closely linked, and this investigation explores how the stakeholders in Angra relate to the possibilities and threats which tourism holds. Angra represents a site where there is a limited influx of tourist, and we can see how most stakeholders speak for a quality-based tourism. In this respect, one could say there is a prevailing consensus among the stakeholders. Finally, this study has assessed the notions of pride, local attachment and identity among the inhabitants in Angra. These sensations are related to the historical cityscape, an environment which also frames personal experiences and processes. The World Heritage Status can trigger a double sense of feelings; on the one side it holds emotions related to pride and recognition, on the other it represents obstacles for living- and developing the city in accordance with the present needs. Angra do Heroísmo is studied for its particularities, yet comparisons made with other studies reveal that the matters and aspects addressed in this thesis can be universal rather than particular. / Avhandlingen er en kritisk kartlegging og analyse av tidligere og pågående diskusjoner, forhandlinger og sosiale prosesser som er relatert til det å leve i og forvalte verdensarvbyen Angra do Heroísmo på Asorene i Portugal. Basert på etnografisk feltarbeid og kvalitative intervjuer med for eksempel innbyggere, kulturminneforvaltningen, politikere og utviklere har formålet vært å forstå hvordan, og med hvilke konsekvenser, ulike verdier, retorikker, interesser og ressurser er mobilisert og gjort til drivende krefter for disse stakeholderne. Avhandlingen gir en kronologisk fremstilling av utvalgte tematikker og diskusjoner fra 1980 og frem til 2012, hvor de første temaene er knyttet til jordskjelvet som rammet byen i 1980, og den påfølgende nominasjonsprosessen til verdensarvlisten som ga Angra do Heroísmo verdensarvstatus i 1983. Et hovedanliggende for denne avhandlingen er problemstillinger knyttet til det å leve i en verdensarvby, med de restriksjoner som følger et klassifisert område. Videre har målet vært å studere myndighetenes- og kulturminnevernets ståsted og deres bevaringspolitikk. I skjæringspunktet mellom hensynet til bevaring og behovet for utvikling oppstår diskusjoner og forhandlinger, og avhandlingen analyserer utvalgte diskusjoner som hovedsakelig er knyttet til utbyggingsprosjekter. Studien viser imidlertid hvordan bevaringsidealer- og politikk endres, og likeledes hvordan myndigheter og autoriteter utfordres av krefter innenfor og utenfor ‘the authorized heritage discourse’. Avslutningsvis gir avhandlingen en analyse av hvilken betydning verdensarvstatusen har for innbyggerne, noe som berører temaene identitet, stolthet og lokal tilknytning. Verdensarven har således en dobbeltsidig størrelse, som på den ene siden trigger følelser som stolthet og annerkjennelse, mens på den andre siden representerer begrensninger og diskusjoner.

This thesis presents a new template for multidisciplinary habitat mapping that combines the analyses of seafloor geomorphology, oceanographic proxies and modelling of associated biologic features. High resolution swath bathymetry of the Faial and western Pico shelves is used to present the first state-of-the-art geomorphologic assessment of submerged island shelves in the Azores. Solid seafloor structures are described in previously unreported detail together with associated volcanic, tectonic and erosion processes. The large sedimentary expanses identified in the area are also investigated and the large bedforms identified are discussed in view of new data on the local hydrodynamic conditions. Coarse-sediment zones of types hitherto unreported for volcanic island shelves are described using swath data and in situ imagery together with sub-bottom profiles and grainsize information. The hydrodynamic and geological processes producing these features are discussed. New oceanographic information extracted from satellite imagery is presented including yearly and seasonal sea surface temperature and chlorophyll-a concentration fields. These are used as proxies to understand the spatio-temporal variability of water temperature and primary productivity in the immediate island vicinity. The patterns observed are discussed, including onshore-offshore gradients and the prevalence of colder/more productive waters in the Faial-Pico passage and shelf areas in general. Furthermore, oceanographic proxies for swell exposure and tidal currents are derived from GIS analyses and shallow-water hydrographic modelling. Finally, environmental variables that potentially regulate the distribution of benthic organisms (seafloor nature, depth, slope, sea surface temperature, chlorophyll-a concentration, swell exposure and maximum tidal currents) are brought together and used to develop innovative statistical models of the distribution of six macroalgae taxa dominant in the infralittoral (articulated Corallinaceae, Codium elisabethae, Dictyota spp., Halopteris filicina, Padina pavonica and Zonaria tournefortii). Predictive distributions of these macroalgae are spatialized around Faial island using ordered logistic regression equations and raster fields of the explanatory variables found to be statistically significant. This new approach represents a potentially highly significant step forward in modelling benthic communities not only in the Azores but also in other oceanic island shelves where the management of benthic species and biotopes is critical to preserve ecosystem health.
