  abstract = {{S}elected high-resolution seismic-reflection profiles and multibeam bathymetry acquired along the convergent {E}cuador margin during the {ATACAMES} cruise on onboard the {R}/{V} {L}'{A}talante ({J}an.15-{F}eb.18, 2012) allow a preliminary evaluation of the neotectonic development and stratigraphic evolution of the margin based on the sismo-stratigraphic analysis of {Q}uaternary sediment preserved on the margin shelf and upper slope. {W}e present three major preliminary results. (1) {T}he evolution of the {E}smeraldas, {G}uayaquil and {S}anta {E}lena canyons. {T}he head of the {E}smeraldas canyon is the location of a continuous significant sediment transport. {T}he {G}uayaquil canyon shows several episodes of deposition and incision. {A}ggrading sedimentation pattern in the canyon records several changes in relative sea-level. {T}he subsidence of the {G}ulf of {G}uayaquil probably contributes to the good preservation of the canyon filling stages. {T}he {S}anta {E}lena canyon is controlled by a {SW}-{NE} trending normal fault. (2) {V}ariations of sediment accumulation and relative vertical motions are shown along-strike the shelf edge. {O}ffshore the uplifted {M}anta peninsula, a pronounced subsidence of the shelf edge is documented by sedimentary clinoforms that have deposited in a morphological reentrant, and have migrated upslope testifying of a local subsidence meanwhile the adjacent {L}a {P}lata {I}sland area underwent uplift. {I}n the {E}smeraldas canyon area, a local uplift of the shelf is documented. (3) {T}wo neotectonic fault systems with a possible transcurrent component are imaged across the shelf edge and upper margin slope offshore {J}ama, and {C}ape {G}alera. {T}his possible transcurrent motion could be related to the reactivation of ancient faults of the upper plate by the subduction. {T}hese preliminary results indicate that the {ATACAMES} data set has a strong potential to evaluate the spatial and temporal contribution of tectonic and climate changes on the structural development and stratigraphic evolution of the {E}cuador continental margin.},
