Última A statistical approach to relationships between fluid emissions and faults: The Sea of Marmara case ArchiMer Henry, P.; Grall, Celine; Kende, J.; Viseur, S.; Ozeren, M. S.; Sengor, A. M. C.; Dupre, Stephanie; Scalabrin, Carla; Geli, Louis. The Sea of Marmara is traversed by the North Anatolian Fault system and also presents abundant emission sites of methane gas into the water column. In order to assess the spatial relationship between gas emissions and active faults, the distribution of distances between gas emission sites and the nearest fault is calculated and compared with the distribution of distances between a uniform random distribution of points (Poisson process representing the null hypothesis of an absence of relationship between gas emissions and faults) and the nearest fault. Interestingly, the distance distribution for the Poisson process is nearly exponential, indicating that the fault map does not have a characteristic scale other than that representing the intensity of the...

We present results from 3D processing of 2D seismic data shot along 100 m-spaced profiles in a 1.8 km wide by 24 km long box during the SISMOSMOOTH 2014 cruise. The study is aimed at understanding the oceanic crust formed at an end-member mid-ocean ridge environment of nearly zero melt supply. Three distinct packages of reflectors are imaged: (1) south-facing reflectors which we propose correspond to the damage zone induced by the active axial detachment fault. Reflectors in the damage zone have dips up to 60° and are visible down to 5 km below the seafloor; (2) series of north-dipping reflectors in the hanging wall of the detachment fault. These reflectors may correspond to damage zone inherited from a previous, north-dipping detachment fault, or small...
