Resumen:	The ESCI-N project in Northwestern Spain was a subprogram of the ESCI Program (Estudios Sísmicos de la Corteza Ibérica). It is formed by four seismic experiments both on and offshore. This project aimed to image the Cantabrian Zone, West Asturian-Leonese Zone and the northern Iberian margin, thus characterizing the crustal structure resulted from the Variscan and Alpine orogenies and the Mesozoic extension related to the opening of the Bay of Biscay.
Descripción:	Two onshore profiles were acquired in E-W and N-S directions through the Variscan and Alpine domains of 140 and 65 km length, ESCI-N1 and ESCI-N2 respectively. Also two offshore profiles ESCI-N3 and ESCI-N4 were obtained with a streamer of 4500 m having 360 channels with a 12.5 m gap between them and a 40 l airgun capacity. ESCI-N3 follows a swerved line in a mainly E-W direction crossing the Variscan structures. ESCI-N4 is a N-S direction profile that crosses both the Cantabrian margin and Le Danois bank Alpine structures. Techincal specifications of offshore profiles: streamer length 4,500 m, 360 channels, group interval 12,5 m and sample rate 4 ms.
