EU-PREFACE - Combining European and African expertise in observations, modelling, and marine ecosystems to improve our understanding and capabilities to predict Tropical Atlantic climate and its impacts (2014- )

To meet its objectives, PREFACE will go beyond the state-of-the-art by bringing together European and African expertises in climate modelling and prediction, oceanography, and fisheries and its management. To close key knowledge gaps, PREFACE will enhance observations, analyse underutilised observations, and use advanced ocean and climate modelling capabilities. In order to achieve this, work in PREFACE is split into four core research areas: the role of ocean processes in climate variability; the evaluation of current climate models and bias reduction; climate prediction in the Tropical Atlantic; and the impacts of climate change on pelagic functional diversity in the Tropical Atlantic with effects on western African fisheries economies. The PREFACE project is funded by the European Commission’s Seventh Framework Programme (2007-2013) – Cooperation.

AWA - Ecosystem Approach to the management of fisheries and the marine environment in West African waters (2013- )

West African coastal countries are heavily dependent on the Atlantic Ocean. Consequently, social development, fisheries, and tourism all face major changes associated with the impact of climate variability and global warming on their upwelling system. Synergistic effects of overexploitation combined with rapid climate change put marine ecosystems under severe pressure.
The AWA project is trilateral German-French-African initiative setting up a strategic partnership capable of developing a vision of an Ecosystem Approach to the Management of the Marine Environment (EAMME) with the required scientific bases. EAMME calls for a multidisciplinary approach combining marine and fishery ecology, biogeochemistry, physical oceanography and climate science. The long-term goal is to develop an ocean observation and modelling platform able to monitor, simulate and forecast some of the most important parameters driving the dynamics of oceanic ecosystems. To better understand the link between biogeochemistry cycles and small pelagic fish stock dynamics, a better knowledge of phyto- and zooplankton compositions is needed as well as of their predator-prey relationships. Such relationships are the key to understand the whole system dynamics.
In support of AWA, several surveys aim to monitor the organisation and functioning of the east border upwelling (EBU) ecosystem.

Partnership: CINTAL - Centro de Investigaçao Tecnológica do Algarve, ULB - Université Libre de Bruxelles (Belgium), COPPE - Universidade Federal do Rio de Janeiro (Brasil), IEAPM - Instituto de Estudos do Mar Almirante Paulo Moreira (Brasil) and C-MARS Canadian Marine Acoustic Remote Sensing Facility (UVic, Canada).

EU-ESONET - European Seas Observatory NETwork - Network of Excellence (NoE) cofunded by the European Commission in the 6th Framework Programme (2007-2011)

ESONET stands for European Seas Observatory NETwork, networking institutions, persons, tools and know-how on deep sea observatories. It aims to promote the implementation and the management of a network of long-term multidisciplinary ocean observatories in deep waters around Europe. It wishes to define an organization ' with the necessary critical mass ' capable of gathering the resources of the participating institutes. The ultimate goal is to define durable solutions through a joint programme of activities.

EU-AquaTerra - Integrated Project (IP) of the 6th EC RTD Framework Programme (2005-2010)

AquaTerra is an integrated project of the 6th EU RTD Framework Programme that aims to provide the scientific basis for an improved river basin management through a better understanding of the river-sediment-soil-groundwater system as a whole, by integrating both natural and socio-economics aspects at different temporal and spatial scales.

HOLOFLOW I & II - Advanced digital holographic microscopy and 4D imagery for applications in water technology and environmental monitoring (2009-2014)

The HoloFlow project aims to develop and implement 4D imaging digital holographic microscopes (DHM) to detect, visualize, track and quantify microscopic particles in dynamic environmental fluids, e.g., to monitor water quality on-line. Thanks to the use of partial-coherent light sources, a patented technology developed at the Microgravity Research Centre (MRC), ULB, improves the performance of digital holographic microscopy, which is a decisive advantage to advance its development also in underwater optics. EHL is interested for marine biology and ecology research projects which motivated the development of an in-situ version of MRC microscope, initially for observation of bubble, plankton and sediment. EHL contributes to in-situ DHM technology development and is in charge of operational testing in ocean and inland waters and of data analysis.

Afin d'observer l'environnement marin de la manière la moins perturbante possible, les procédés utilisant l'acoustique sous marine discrète permettent la haute résolution temporelle, le suivi long terme et à moindre coût pour celui qui maitrise les outils de mesures et d'analyse des sons et qui peut corréler la production sonore d'un milieu avec son état. Le thème de l'océanographie acoustique est inclus dans le projet scientifique de l'axe 5 du GIS Europôler Mer. Cette recherche est menée en collaboration avec le trinôme brestois ENSIETA, SHOM et Océanopolis, et avec Pêches et Océans, Canada (MPO).

BC-IWBCS-ACOUST-OBS - Toward acoustic observatories for studying the dynamics of the ''Brazil Current - Intermediate Western Boundary Current'' system

Acoustic tomography is a powerful tool for oceanic data collection due to its unique ability to sample three-dimensional synoptic fields. Moreover the acoustic tomography can provide time series of these fields at a low cost. This research explores how tomographic data can help for studying the meso-scale dynamics of BC-IWBCS. The project develops alternative methods for providing synoptic data for operational oceanography, including field estimates for initialization and assimilation into numerical models.

CONSONNES - Contrôle des sons naturels et synthétiques - financé par l'Agence nationale de la Recherche

CONSONNES vise à rassembler autour du Laboratoire de Mécanique et d'Acoustique (UPR CNRS 7051, Marseille), de l'IRCAM (UMR 9912, Paris) et de l'ENST (LTCI, UMR 5141, Paris) des spécialistes nationaux et internationaux afin de faire avancer significativement la connaissance et les dispositifs expérimentaux dans le domaine du contrôle des sons produits par les instruments de musique acoustiques et leurs paradigmes numériques. Les instruments à vent et à cordes frottées ont un fonctionnement par essence non linéaire (auto-oscillations), le musicien fournissant de l'énergie principalement à très basse fréquence, et sont particulièrement concernés par la problématique contrôle. La description, la mesure et la modélisation de leur fonctionnement et de son résultat sonore soulèvent en effet des problèmes fondamentaux nécessitant pour être abordés efficacement l'association de compétences dans des domaines très divers.

CORDOPHONES - Altérateurs de timbre des cordophones - projet Action 1, financement par le Ministère de la Politique Scientifique (2010-2013)

Les altérateurs de timbre existent dans toutes les aires culturelles et dans toutes les familles organologiques. Un altérateur de timbre peut se définir comme un dispositif : 1. Dont l'effet est partie intégrante du timbre des sons produits par l'instrument ; 2. Qui n'est pas actionné directement par le musicien pendant le jeu ; 3. N'est pas indispensable à la production, la transmission ou l'amplification de la vibration, ni à l'équilibre mécanique de l'instrument. Les objectifs principaux de ce projet sont 1) l'analyse de la manière dont l'altération est mécaniquement produite et l'effet acoustique et perceptif de l'altérateur 2) l'analyse de la manière dont les timbres altérés sont utilisés dans les répertoires musicaux et sont conceptualisés dans leur culture ; 3) la catégorisation les altérateurs et les timbres altérés, dans le but d'intégrer les altérateurs dans les bases de données et les classifications des instruments de musique. Ce projet vise à une meilleure compréhension de la gestion du timbre et la reconnaissance de l'importance du timbre dans les recherches organologiques.
