    Description / Table of Contents: La biologie des systèmes, ou biologie systémique, est une approche de la biologie qui consiste à englober la complexité des interactions entre les entités biologiques dans un tout systémique. Le but étant de comprendre l'émergence de propriétés physiologiques ou fonctionnelles.Approches symboliques de la modélisation et de l'analyse des systèmes biologiques présente les apports de méthodes formelles issues de l'informatique pour la modélisation de la dynamique des systèmes biologiques. Il traite plus spécifiquement des méthodes symboliques, c'est-à-dire qui peuvent établir des propriétés qualitatives des modèles.Cet ouvrage expose différentes approches liées à la sémantique, au langage, à la modélisation et à leur lien avec les données, et nous permet d'examiner des problèmes fondamentaux et des défis auxquels nous confronte la biologie des systèmes. Une première partie regroupe des travaux qui s'appuient sur les diverses données accessibles pour construire des modèles alors que la seconde présente des contributions autour des questions de la sémantique et des méthodes formelles.

    Description: The present deliverable is a continuation of deliverable D4.21, in which we presented the first steps in the design and preparation of different reanalysis simulations assimilating glider data. We here show the assessment and intercomparison of CMCC MedFS and SOCIB WMOP systems experiments. We have performed, for each system, three different experiments, running a one-year simulation during 2017. We compare a free-run simulation without data assimilation (FREE) and two reanalyses including assimilation: one considering only the generic data sources included in each operational system (NOGLID) and another one adding glider observations to the previous dataset (GLIDER). The models are assessed and inter compared to each other, focusing on the performance to represent the observed 3D structure of the ocean and on their capacity to recreate physical processes, as an anticyclonic eddy structure present in the Balearic sea. Results show how in both systems the use of glider observations can help to further improve the results obtained when using data assimilation, helping to an enhancement of the forecasting capabilities.
