Among the gaps in information required to develop science-based marine spatial planning, we identified the need for spatialised information on fishers and seabird spatial behaviour. In interaction between UFPE, UFRPE and IRD we performed a field work around Fernando de Noronha to study fishers and seabird behaviour at sea (GPS, TDR, GLS deployement and recovery). This activity contributed directly to the tasks 2.2 and 2.3. After the fieldwork, the collected data were modelled in order to segment the tracks into different behavioural modes (travelling, searching, fishing) what contributed directly to objective 2.4 (Innovative use of data and models and ecosystem scenarios).
