Abstract:
In September of 2018, the Spanish research vessel Sarmiento de Gamboa shot the seismic profile FRAME-p03 across the continent-to-ocean transition zone in the Iberia Abyssal Plain of the Western Iberia passive continental margion to the west of Portugal. Seismic shots were recorded on 30 ocean-bottom-seismometers (OBS) and ocean-bottom-hydrophones (OBH). Spanish instruments were OBS from the Spanish Pool operated by the Marine Technology Unit (UTM) of Consejo Superior de Investigaciones Científicas (CSIC) and German istruments were OBH from the GEOMAR Helmholtz Centre for Ocean Research Kiel. Seismic data in SEGY format of the all seismic stations of both partners are archived at the PANGAEA Datacenter. Please note that the data have a time offset of 1 sec and a reduction velocity of 8 km/s. The seismic FRAME (Formation of Geological Domains in the Western Iberian Margin and Tectonic Reactivation of their Limit) cruise was funded by the Spanish Ministry of Science.
