FRENCH CALLS FOR COLLABORATION (FRENCO) Idea: French Guiana coastal dynamics depends on Amapá coastal dynamics. Although there is a geographic continuity of ecosystems and the influence of Amazon sediment discharge, functioning, phenomena and characteristics may be extremely different. Taking benefits from understanding of both regions is promising for developing and calibrating a range of methods in biology, ecology, sedimentology, geomorphology and remote sensing. French scientists need collaborations with Brazilian scientists to help their studies dedicated to the study of the French Guiana coastal dynamics. These collaborations may be initiated as following. BRASILIAN CALLS FOR COLLABORATION (BRANCO) Idea: The study of the Amazon coastal region requires a wide range of techniques, skillness, materials which are difficult to combine at the same time in the same region of study without collaborations. Although the following propositions of collaborations do not give direct information for the study of French Guiana coastal dynamics, the development of a common base of methodologies to measure processes occurring in the Amapá or Pará regions may contribute to reinforce efficiency of methodologies used in other regions. Within this frame, the BRANCO proposition combines the formation of a student (1 month?) which will have to user material, method in another context and will come back to its region of experiment in Brasil to apply it. Principle: A student in ‘mestrado’ or ‘graduação’ of the north-eastern Brazil is coached by a local scientist within the frame of its university formation. Theme and proposal of collaborations are discussed by Brazilian and French scientists in order to define a work planning adapted for all. One of the main criteria should be a opportunity for a rapid publication in an international journal.
