The Southern Gas Corridor is a European Commission initiative with the aim of facilitating the diversification of the routes and sources of gas imported into Europe in the hope of reducing the EU’s dependence on Russia. Although the Southern Gas Corridor – alongside the EU’s flagship Nabucco project, which constitutes a part of the Corridor – was originally conceived as a means of furthering the interests of the West (officially the EU but in practice also the US), the implementation of the project has become possible almost exclusively thanks to measures taken by Azerbaijan and Turkey. Consequently, a project which the EU had hoped would protect its political interests has indirectly given Azerbaijan and Turkey considerable influence over the EU, since it is those two countries that have effectively begun to define the shape of the Southern Corridor. This became particularly clear when the Trans-Anatolian gas pipeline (TANAP) agreement was signed on 26 June 2012. If the EU wishes to ensure that the implementation of the Southern Gas Corridor project retains at least some of its original design, Brussels has little choice but to take into account the preferences of Azerbaijan and Turkey at the expense of its own original plans.

A society acts sustainably if it ensures the long-term stability and productivity of ecological, sociopolitical and economic systems. In the past, issues of sustainability were typically handled separately, neglecting individual measures’ effects on other elements implied by a comprehensive conception of sustainability. The challenge ahead is to develop a holistic strategy for sustainable economic activity that takes into ac-count interdependencies between the various aspects of sustainability, and does not seek to solve problems of sustainability at other aspects’ expense.

Ce mémoire explore la relation qui lie démocratie et légitimité politique, dans une perspective épistémique. La démocratie, dans son acception la plus générale, confère à chacun la possibilité de faire valoir les intérêts qu'il estime être les siens et ceux de sa communauté, en particulier à l’occasion d’un scrutin. Cette procédure décisionnelle qu’est le vote consacre ainsi en quelque sorte la liberté et l’égalité dont profitent chacun des citoyens, et confère une certaine légitimité au processus décisionnel. Cela dit, si le vote n’est pas encadré par des considérations épistémiques, rien ne garantit que le résultat politique qui en découlera sera souhaitable tant pour les individus que pour la collectivité: il est tout à fait permis d’imaginer que des politiques discriminatoires, économiquement néfastes ou simplement inefficaces voient ainsi le jour, et prennent effet au détriment de tous. En réponse à ce problème, différentes théories démocratiques ont vu le jour et se sont succédé, afin de tenter de lier davantage le processus démocratique à l’atteinte d’objectifs politiques bénéfiques pour la collectivité. Au nombre d’entre elles, la démocratie délibérative a proposé de substituer la seule confrontation d’intérêts de la démocratie agrégative par une recherche collective du bien commun, canalisée autour de procédures délibératives appelées à légitimer sur des bases plus solides l’exercice démocratique. À sa suite, la démocratie épistémique s’est inspirée des instances délibératives en mettant davantage l’accent sur la qualité des résultats obtenus que sur les procédures elles-mêmes. Au final, un même dilemme hante chaque fois les différentes théories : est-il préférable de construire les instances décisionnelles en se concentrant prioritairement sur les critères procéduraux eux-mêmes, au risque de voir de mauvaises décisions filtrer malgré tout au travers du processus sans pouvoir rien y faire, ou devons-nous avoir d’entrée de jeu une conception plus substantielle de ce qui constitue une bonne décision, au risque cette fois de sacrifier la liberté de choix qui est supposé caractériser un régime démocratique? La thèse que nous défendrons dans ce mémoire est que le concept d’égalité politique peut servir à dénouer ce dilemme, en prenant aussi bien la forme d’un critère procédural que celle d’un objectif politique préétabli. L’égalité politique devient en ce sens une source normative forte de légitimité politique. En nous appuyant sur le procéduralisme épistémique de David Estlund, nous espérons avoir démontré au terme de ce mémoire que l’atteinte d’une égalité politique substantielle par le moyen de procédures égalitaires n’est pas une tautologie hermétique, mais plutôt un mécanisme réflexif améliorant tantôt la robustesse des procédures décisionnelles, tantôt l’atteinte d’une égalité tangible dans les rapports entre citoyens.

Subaerially erupted tholeiites at Hole 642E were never exposed to the high-temperature seawater circulation and alteration conditions that are found at subaqueous ridges. Alteration of Site 642 rocks is therefore the product of the interaction of rocks and fluids at low temperatures. The alteration mineralogy can thus be used to provide information on the geochemical effects of low temperature circulation of seawater. Rubidium-strontium systematics of leached and unleached tholeiites and underlying, continentally-derived dacites reflect interactions with seawater in fractures and vesicular flow tops. The secondary mineral assemblage in the tholeiites consists mainly of smectite, accompanied in a few flows by the assemblage celadonite + calcite (+/- native Cu). Textural relationships suggest that smectites formed early and that celadonite + calcite, which are at least in part cogenetic, formed later than and partially at the expense of smectite. Smectite precipitation occurred under variable, but generally low, water/rock conditions. The smectites contain much lower concentrations of alkali elements than has been reported in seafloor basalts, and sequentially leached fractions of smectite contain Sr that has not achieved isotopic equilibrium. 87Sr/86Sr results of the leaching experiments suggest that Sr was mostly derived from seawater during early periods of smectite precipitation. The basalt-like 87Sr/86Sr of the most readily exchangeable fraction seems to suggest a late period of exposure to very low water /rock. Smectite formation may have primarily occurred in the interval between the nearly 58-Ma age given by the lower series dacites and the 54.5 +/- 0.2 Ma model age given by a celadonite from the top of the tholeiitic section. The 54.5 +/- 0.2 Ma Rb-Sr model age may be recording the timing of foundering of the Voring Plateau. Celadonites precipitated in flows below the top of the tholeiitic section define a Rb-Sr isochron with a slope corresponding to an age of 24.3 +/- 0.4 Ma. This isochron may be reflecting mixing effects due to long-term chemical interaction between seawater and basalts, in which case the age provides only a minimum for the timing of late alteration. Alternatively, inferrential arguments can be made that the 24.3 +/- 0.4 isochron age reflects the timing of the late Oligocene-early Miocene erosional event that affected the Norwegian-Greenland Sea. Correlation of 87Sr/86Sr and 1/Sr in calcites results in a two-component mixing model for late alteration products. One end-member of the mixing trend is Eocene or younger seawater. Strontium from the nonradiogenic endmember can not, however, have been derived directly from the basalts. Rather, the data suggest that Sr in the calcites is a mixture of Sr derived from seawater and from pre-existing smectites. For Site 642, the reaction involved can be generalized as smectite + seawater ++ celadonite + calcite. The geochemical effects of this reaction include net gains of K and CO2 by the secondary mineral assemblage. The gross similarity of the reactions involved in late, low-temperature alteration at Site 642 to those observed in other sea floor basalts suggests that the transfer of K and C02 to the crust during low-temperature seawater-ocean crust interactions may be significant in calculations of global fluxes.

Downhole bulk-sample and clay-mineral analytical results for Sites 558 and 563 are presented in this chapter. These results show a Tertiary climatic and hydrologic evolution similar to that at other DSDP drill sites in the northeastern Atlantic Ocean (Sites 398, 403-406, 548-550, 552-555). The sediments recovered at both sites are primarily calcareous and chalky oozes characterized by >90% carbonate and minor quartz and plagioclase feldspar. Clay minerals smectite, kaolinite, illite, and chlorite are present throughout the cores; upsection, illite increases at the expense of smectite. The clay mineralogy suggests climatic cooling and increased ocean circulation during the Miocene. Intervals rich in very fine grained (<2 µm) quartz suggest times of increased eolian input. This could have resulted from development, during Oligocene and late Miocene time, of an arid, desertlike sediment provenance that lasted until the present day.
