Résumé : The present working document aims to list the main environmental databases (including in-situ observations, remote-sensing data and ocean models outputs), that are currently available on the Net and of interest in open-sea fisheries biology and ecology.
Ce document a pour objet de lister les principales bases de données environnementales (concernant les données in-situ, satellitaires et les sorties de modèles océaniques), qui sont actuellement disponibles sur la toile et d’intérêt pour l’écologie halieutique se rapportant aux ressources thonières.
El objetivo de este documento es presentar una relación de las principales bases de datos medioambientales (sobre datos in situ, vía satélite y valores de salida de los modelos oceánicos) que están disponibles actualmente en la red y que revisten interés para la ecología pesquera relacionada con los recursos atuneros.

Résumé : This paper provides an exploratory analysis aiming to seek whether the colour of environmental noise theory could help in understanding the intriguing reproductive strategy of Atlantic bluefin tuna (BFT). A frequency-based approach based on spectral exponents, f(beta) with beta < 0, is chosen and applied on 10 biogeographical provinces covering the North Atlantic. The major BFT spawning area, i.e. the Mediterranean Sea, was the only one to display a pink power spectrum, whereas open ocean regions displayed more reddened fluctuations, i.e. greater variance at low frequencies. Environmental noise in the Mediterranean could, thus, offer more favourable characteristics on the long-term than the open ocean. The implications of these findings are discussed in regards to medium and long (possibly evolutionary) time scales.
