Objective | The IGUANES campaign (Instabilities and fluid outlets of the Guyana-Suriname transforming margin) concerns the investigation of the relationships between structure, underwater instability and cold fluid outlets along the Guyana-Suriname transforming margin. This margin shows a very interesting structural variability with in particular a part tilted towards the sea which does not have a marginal wrinkle. This device seems to influence the location and geometry of many sliding masses and very intense fluid outlets. A field of giant pockmarks seems to be set up in relation to the post-rift tilted series. To constrain the atypical nature of this margin and the couplings between structure, fluid outlets and surface slides, a multi-scale acquisition was carried out in order to integrate these different objects:
