    In the framework of the SNO/SOERE MOOSE (Mediterranean Ocean Observing System on Environment https://www.ir-ilico.fr/Les-reseaux-elementaires/Fiches-d-identite-des-reseaux-elementaires/MOOSE ) program, the Mediterranean Institute of Oceanography is operating coastal High Frequency Surface Wave Radars (HF radar) on the North Western Mediterranean coast. This activity is also supported by the following European Research Infrastructure Jerico-Next (https://www.jerico-ri.eu), and Intereg MED programs as Impact and Sicomar +. HF radar provide high resolution (3­-5 km), synoptic view of surface currents from the shore up to 80 km off shore at hourly time scales. The measurement principle is based on the Doppler effect created by an additional current on the intrinsic speed of the waves selected by radar-sea interactions, called Bragg waves, having a wavelength of half that of the radar e.m. waves and propagating in the axis of observation (radial currents). A single radar scans the sea in azimuth and determines the radial components of the current at each adjacent cell along each azimuth. Two separate radars for the same area from different angles then collect the information necessary for mapping vector current from the combination of the two sets of radial components. The HF radar data set is made of monthly averaged surface currents, geo-referenced on cartesian lon/lat coordinates. The radial velocities maps are provided applying a Direction Finding technique (instead of traditional Beam Forming) not only to the full array of antenna but also to subarrays made of a smaller number of sequential antennas, a method which we refer to as "antenna grouping". Radials from Peyras-Peyras and Porquerolles-Benat are computed to reconstruct the vector field.

    The Health and Demographic Surveillance System (HDSS) in Niakhar, a rural area of Senegal, is located 135 km east of Dakar. This HDSS has been set up in 1962 by the Institut de Recherche pour le Développement (IRD) to face the shortcomings of the civil registration system and provide demographic indicators. Some 65 villages were followed annually in the Niakhar area from 1962 to 1969. The study zone was reduced to eight villages from 1969 to 1983, and from then on the HDSS was extended to include 22 other villages, covering a total of 30 villages for a population estimated at 45,000 in December 2013. Thus 8 villages have been under demographic surveillance for almost 50 years and 30 villages for 30years. Vital events, migrations, marital changes, pregnancies, immunization are routinely recorded (every four months). The database also includes epidemiological, economic and environmental information coming from specific surveys. Data were collected through annual rounds from 1962 to 1987; rounds became weekly from 1987 to 1997; routine visits were conducted every three months between 1997and 2007 and every four months since then. The current objectives are 1) to obtain a long-term assessment of demographic and socio-economic indicators necessary for bio-medical and social sciences research, 2) to keep up epidemiological and environmental monitoring, 3) to provide a research platform for clinical and interdisciplinary research (medical, social and environmental sciences). Research projects during the last 5 years are listed in Table 2. The Niakhar HDSS has institutional affiliation with the Institut de Recherche pour le Développement (IRD, formerly ORSTOM). * Niakhar HDSS INDEPTH Core Dataset 1984-2016 (Release 2018).

    Communities of Rhopalocera (Lepidoptera) butterflies in 24 urban parks in Marseille Sampling of Rhopalocera communities: 7 to 12 transects in each of 24 urban parks in Marseille every 2 years since 2008. Increasing numbers of cities are currently developing sustainable policies aimed at promoting urban biodiversity and ecological dynamics through the planning of green networks and the implementation of more sustainable management practices. These human activities can strongly influence environmental factors on which the organization of ecological communities at different scales depends. Thus, it is of fundamental importance to understand the relative impact of local management, green space design and landscape features on the distribution and the abundance of species in urban areas. On the basis of 2 years of butterfly surveys in urban public parks within an extensive Mediterranean metropolitan area, Marseille (South-East France), the aim of this paper is to provide a better understanding of the effect of these three environmental scales (plot, park, landscape) on the composition and organization of species assemblages. Using variation partitioning and nestedness analysis on ecological data aggregated at plot-level and park-level respectively, we demonstrate the preponderant effect of landscape scale features on urban butterfly assemblages. Our results also highlight an important co-variation of plot management, park layout and urban landscape features, in their interaction with the community structure of urban butterflies. Although there is no significant species-area relationship, significantly nested patterns arise in species composition. Selective colonization appears as a driving force constraining the constitution of species assemblages within the city. However, a prospective study on adjacent more natural areas suggests that biotic limitations, interspecific competition and habitat filtering may play an important role if a larger portion of the urbanization gradient is explored, which remains to be investigated.

    L’île de Bagaud, réserve intégrale du Parc National de Port Cros (PNPC), fait actuellement l‘objet d’un programme décennal de restauration écologique en vue de la préservation de son patrimoine naturel. Cette restauration consiste à contrôler deux espèces exotiques envahissantes : le rat noir (Rattus rattus) et la griffe de sorcière (Carpobrotus sp.). Débuté en 2010, ce programme permet l’étude de plusieurs groupes taxonomiques avant (2010-2011) et après contrôle (2013-2019) : (1) la flore, (2) les arthropodes épigés et les insectes volants, (3) les squamates, (4) les oiseaux terrestres nicheurs et (5) les oiseaux marins nicheurs. Ce projet fédère une large communauté d’acteurs académiques et non-académiques autour d’un objectif commun : contrôler et si possible éradiquer les espèces invasives de la réserve intégrale et suivre la résilience des groupes taxonomiques cités ci-dessus. Partenaires pour le suivi et l’analyse des données : IMBE, PNPC, CBNMed, association Reptil’Var, association DREAM et LPO. Autres partenaires : PIM, INRA, Conservatoire du Littoral, Domaine du Rayol, Naturoscope, UE, Natura2000, TLV, Région Sud, Naturalia Consultants en Environnement.

    Le site d'observation de Port-Miou est rattaché au Service National d'Observation Karst, dont l'objectif est d'assurer le suivi physico-chimique d'un ensemble de sources et d'hydrosystèmes karstiques sur le territoire français, représentatif du fonctionnement hydrogéologique de ce type d'aquifère. Les sources karstiques côtières de la baie de Cassis ont été identifiées pour le suivi des apports d'eau saumâtre en mer (lien continent-océan) et l'étude du mécanisme d'intrusion saline en aquifère hétérogène et autour de la Méditerranée. Ce sont également des points d'observation de l'impact des changements globaux sur la qualité de l'eau souterraine en zone côtière. Enfin, l'un des objectifs des sites du SNO Karst est d'améliorer les connaissances sur les aquifères carbonatés pour aider à la gestion durable des ressources en eau. La source sous-marine de Port-Miou présente la particularité d'être accessible dans les terres, sur un site constituant un véritable laboratoire souterrain avec un barrage obturant la galerie karstique. Le suivi physico-chimique et biologique est ainsi facilité.

    AcoustRivNN proposes to develop a system to estimate the flow and the granulometry of the sediment transport in a river from the acoustic pressure generated by the latter using methods from artificial intelligence. The estimation of the sediment flow carried by water, in rivers or estuaries, is a crucial issue for the management of the latter, allowing to carry out scientific studies, restoration or prevention projects, as well as operational works. Given the lack of effective methods to estimate the flow of sediment, the AcoustRivNN project proposes to provide a "proof of concept" by developing an original system based on deep learning to estimate the flow of coarse sediments from the simple acoustic pressure generated by the latter and measured by hydrophones. The originality of this project lies, in particular, in its interdisciplinary aspect proposing to adapt methods from artificial intelligence particularly effective in many applied fields. This project, which is part of the transversal axis 2: "Observations/information systems/modeling" of the ECCOREV federation, is structured in two phases: - Phase I proposes to build an acoustic database referenced in the laboratory necessary for the training of a neural network. - Phase II aims to develop a neural network model to characterize the acoustics of sediment flow.
