Resumo: | Today, only 15% of the global ocean floor has been mapped at a high resolution of around 100 meters. The French Research Institute for the Exploitation of the Sea (Ifremer) participates in the acquisition of high-resolution seafloor depth data called "bathymetric data", by deploying its oceanographic vessels equipped with multibeam echo sounders. This internship within the ocean mapping service of Ifremer allowed, firstly, the processing of raw bathymetric data, acquired between 1991 and 2018 over the central North Atlantic mid-ocean ridge, and to compile them in digital terrain models. These models are necessary to improve geologic investigations, and they are available to scientists in Ifremer and elsewhere. The models also contribute to international bathymetric models and research projects. In a second step, data analyses were carried out in collaboration with Ifremer researchers : a study of the abyssal hill structures of the mid-Atlantic ridge between 14°N and 35°N was carried out in order to better understand the plate tectonic movements and a structural geology map was created for a polymetallic sulphides exploration zone.
