IIn a world of increasing atmospheric CO2, there is intensified interest in the eco-physiology of photosynthesis and increasing attention is being given to carbon exchange and storage in natural ecosystems. We need to know how much photo-synthesis of terrestrial and aquatic vegetation will change as global CO2 increases. Are there major ecosystems, such as the boreal forests, which may become important sinks of CO2 and slow down the effects of anthropogenic CO2 emissions on climate? Will the composition of the vegetation change as a result of CO2 increase? Fortunately, some 30 years of intensive research in the eco-physiology of photosynthesis are serving well as regional and global models of photosynthesis and carbon exchange are being developed and refined. This volume reviews the progress which has been made in understanding photosynthesis in the past few decades at several levels of integration from the molecular level to canopy, ecosystem and global scales.

This text provides a mathematically oriented introduction to the theory of the large scale ocean circulation accessible for anyone with an elementary knowledge of mathematics and physics. The book consists of four parts. In part I (chapters 1-4) a brief description is provided of the ocean circulation. The mathematical framework of the governing equations of ocean flows is also presented. In addition, important concepts such as potential vorticity which are necessary to model and understand large-scale ocean currents are introduced. In part II (chapters 5-10), the theory of the midlatitude wind-driven ocean circulation and its variability is presented. Considering model development, there is a top-down approach and reduced equations, such as the the Sverdrup balance, are derived by using scaling techniques and asymptotic methods. Part III (chapters 11-12) focusses on the understanding of equatorial currents and El Nino. In the last part IV, chapters 13-16, the theory of planetary scale flows is presented, covering topics such as the thermocline problem, the Antarctic Circumpolar Current, the stability of the thermohaline circulation and the Arctic Ocean circulation. Five exercises are formulated at the end of each chapter. Many of these exercises are aimed to further develop methodological skills and to help readers become familiar with the physical concepts. New material is presented in only a few of the exercises. Fully worked out answers to all exercises can be downloaded from the book web site

Marine fronts are part of the structural complexity of the sea; they are narrow boundaries separating different water masses. Fronts are caused by diverse forcing and occur throughout the world ocean at several spatial and temporal scales. Unlike terrestrial ecotones, they show high biological production, affecting pelagic and benthic organisms of all trophic levels; consequently they are important for fisheries. Solar energy stimulates biological production in the entire biosphere, but in the sea it needs to be complemented by auxiliary energy to replenish plant nutrients; a significant quantity of mechanical energy becomes available for biological production at fronts. Global change is redistributing auxiliary energy in the oceans; consequently fronts are ideal sites for early monitoring of global change effects. Fronts also provide retention mechanisms for plankton in the highly dispersive marine environment; and become landmarks and beacons important for migrations or meeting of some species in a traceless realm.

L’objectif de ce mémoire est d’évaluer l’impact environnemental du système de boues de forage en Algérie dans la mer entre Skikda et Annaba. Les boues aqueuses (WBM) et les boues à base de pétrole (OBM) sont utilisées lors du forage de puits dans la mer projetée entre Skikda et Annaba et présentent un potentiel de pollution important. Une approche d’évaluation du cycle de vie (ACV) est utilisée pour évaluer les effets de nombreux systèmes de boues de
forage à toutes les étapes de leur cycle de vie, comme leur utilisation, leur traitement et leur élimination. Les impacts environnementaux sont comparés à deux scénarios de traitement correspondant à la gestion des déchets de forage déjà appliqués à Hassi Messaoud : stabilisation / solidification et absorption. L’analyse d’impact à l’aide de la méthode CML et du modèle LCIA est effectuée dans SIMAPRO7. Cette évaluation identifie la toxicité humaine et marine comme la principale catégorie d’impact dans ce contexte marin particulier et identifie les contributions aux émissions.
L’impact sur l’environnement marin local est le plus important cycle de vie des boues de forage est principalement lié aux émissions provenant des stocks, des déblais traités et du forage de phase 16 pour les aquifères. Les hydrocarbures aromatiques et les minéraux, en particulier le baryum, le zinc, l’antimoine, l’arsenic et l’aluminium, en sont les principales substances. Pour la comparaison des scénarios de traitement, la stabilisation/solidification semble être la
meilleure solution, car elle a l’effet le plus faible dans les deux catégories dominantes en raison de la réduction des déchets : stockage des boues évité dans la fosse de réserve. Le deuxième meilleur scénario est l’adsorption thermique, qui a l’effet cancérogène le plus faible en raison de la réduction des hydrocarbures moins de 1 % et des effets évités du pétrole récupéré. La modélisation du devenir des substances toxiques sera améliorée en tenant compte de leur impact spécifique sur le site.

Wildlife researchers and ecologists make widespread use of multivariate statistics in their studies. With its focus on the practical application of the techniques of multivariate statistics, this book shapes the powerful tools of statistics for the specific needs of ecologists and makes statistics more applicable to their course of study. Multivariate statistics for wildlife and ecology research gives the reader a solid conceptual understanding of the role of multivariate statistics in ecological applications and the relationships among various techniques, while avoiding detailed mathematics and underlying theory. More important, the reader will gain insight into the type of research questions best handled by each technique and the important considerations in applying each one. Whether used as a textbook for specialized courses or as a supplement to general statistics texts, the book emphasizes those techniques that students of ecology and natural resources most need to understand and employ in their research. Detailed examples use real wildlife data sets analyzed using the SAS statistical software program.

Database issues in geographic information systems approaches several important topics in GIS from a database perspective. Database management has a central role to play in most computer-based information systems, and is expected to have an equally important role to play in managing information in GIS as well. Existing database technology, however, focuses on the alphanumeric data that are required in business applications. GIS, like many other application areas, requires the ability to handle spatial as well as alphanumeric data. This requires new innovations ii data management, which is the central theme of this monograph. The monograph begins with an overview of different application areas and their data and functional requirements. Next, it addresses the following topics in the context of GIS: representation and manipulation of spatial data, data modeling, indexing, and query processing. Future research directions are outlined in each of the above topics. The last chapter discusses issues that an emerging as important areas of technological innovations in GIS.

This book gives an overview of statistical turbulence modeling with applications to oceanography and limnology. It discusses how these models can be derived from the Navier-Stokes equations, step by step simplifications result in models applicable to numerical simulations for realistic solutions. Results from one dimensional simulation are shown for various oceanic and limnic water column studies. The integration of these turbulence models in three dimensional models is discussed and some selected results are shown. The two equation turbulence models prove to be a good compromise between accuracy and economy are published as a Fortran source code on the internet in the framework of the general ocean turbulence model (GOTM). This website also provides forcing and validation data for several idealized scenarios. The book and the home page enable graduate students and researchers to understand the theory and provide tools for the models.

Life in its diversity is the greatest resource on our planet and represents the very foundation of human existence. Only in the last two décades hâve we become aware of the dimension of biodiversity: some 1.75 millions différent organisms are known to science - but assessments strongly indicate that there are aboutfen times as manyspecies existing between thé polar circles and tropical rain forints». New and exciting species are being discovered every day - at the same time we can observe a dramatic loss of biodiversity within the global change: extinction rates are probably unequaledin the natural history of ourworld. The géographie distribution of biodiversity is very unequal with the highest dtions in the tropical forests and certain subtropical regions.The developing countries possess the true wealth of the global genetic resources - but the capacities for bip- diversity research are concentrated in thé highly industrialized countries.The Rio con-vention on Biological Diversity, megadiversity countries and megadeveloped countries are the scénario for biodiversity.
