  • The activity calendars of fishing vessels reconstituted each year provide access to the following monthly fishing data: main operating port, number of pepole on board, number of days at sea and of, trade (s) practiced ( s), exploited fishing areas and their distance from the coast. Annual data on the dimension and mesh size of the engines used to practice a trade are also provided.

  • The observation of sales consists of periodically measuring the size of individuals of the main species at auctions and landing points, taking into account the commercial names used at the point of sale. This system, called ObsVentes, is applied in metropolitan France and in the French overseas territories : Guyane, Guadeloupe, Martinique, Réunion and Mayotte.

  • SACROIS is a data crossing algorithm that produces professional fishing activity data series (validated, consolidated and qualified production and effort data) for the vessels registered in the Community Fishing Fleet (CFP) file. SACROIS selects the best of the available information sources to produce the reference fishing activity data. SACROIS consists of an operational application for reconciliation, verification and consistency checks of different unitary data streams. The SACROIS algorithm does not correct the data, its objective is to : - provide the best possible estimate of the various elements making up a tide from the available data sources - to identify the incompleteness of the various data sources and to propose a synthesis completed by indicators of data qualification resulting from the crossings. Twice a month, the SACROIS algorithm produces a new data source, a synthesis of all the available data sources: the reconstructed SACROIS tides. The SACROIS data have been calculated since 2000 for all fleets for which data are available: - North Sea - Channel - Atlantic (excluding tropical seiners), - Mediterranean (excluding bluefin seiners), - DOM (Reunion, Mayotte, French Guiana and the West Indies).

  • These data provide information on the characteristics of shipowners and vessels: registration, year of construction, material, length, port, place of registration, membership of the FPC file, tonnage, power.

  • Elevational Transect on the East side of the Piton des Neiges. Implementation of small permanents plots every 200 m of height between 350 m and 2950 m. Differents biotics and abiotics parameters are observed on plots: - Climatic variables (T, RH) - Physico-chemical analyses of grounds - Vegetation and arthropods inventories...

  • Climatic data from the meteorological station of Mare Longue (primary forest, 300m of elevation) UMR PVBMT

  • Elevational Transect on the West side of the Piton des Neiges. Implementation of small permanents plots every 200 m of height between 750 and 2350 m. Differents biotics and abiotics parameters are observed on plots: - Climatic variables (T, RH) - Physico-chemical analyses of grounds - Inventories of vegetation, arthropods

  • Entre 2017 et 2022, l’association Centre d’Etude et de Découverte des Tortues Marines (CEDTM) est en charge de mettre en œuvre une mesure de compensation de la Nouvelle Route du Littoral MCM05 intitulée "Amélioration des conditions de quiétude des mammifères marins et des tortues marines pour la durée du chantier" et financée par la Région Réunion. Dans le cadre de ce programme, des sorties régulières en bateau sont réalisées pour non seulement répertorier les observations des mammifères marins et tortues marines mais également pour sensibiliser les usagers de la mer. Ici deux couches par année d'observation sont disponibles, une couche point permettant de répertorier toutes les observations du Dauphin long bec (Stenella longirostris) ; une couches polygone, correspondant à un maillage de 1 km de côté et permettant de visualiser les observations du Dauphin long bec en fonction de l'effort d'échantillonnage.

  • Cette carte représente les fréquence d'observations de la Baleine à bosse (Megaptera novaeangliae) autour de La Réunion (Océan Indien). Cette étude a été réalisée par Globice. Pour une plus grande homogénéité, les données fournies sont issues de la période de prospection 2008-2012. La grille se présente sous la forme d’un maillage de 2km sur 2km de coté.
