Descrição: Seismic reflection data document for the first time the existence of a BSR in a limited area west of the Dnieper Canyon in the northwestern Black Sea. Seismic wide-angle data suggest that gas hydrates occupy in average 15+/-2% of the pore space in a zone of 100 m in thickness. A conservative quantification of the amount of methane associated with this gas hydrate occurrence is about 12+/-3times10<11< m<3< (0.6+/-0.2 Gt of methane carbon). Conductive heat flow deduced from the BSR depth is in the range of 21+/-6 to 55+/-15 mW m<-2<. [PUBLICATION ABSTRACT]
