A relatively large number of large-scale seismic reflection transects acquired in the Iberia Peninsula has been compiled into a geophysical data base. These data has been made available through an easy access internet web page (http://xeon.ija.csic.es) . The key objective of this effort is to provide ready access to geophysical data, such as images of the Earth's basement geology and deep crust and upper mantle, and thus contribute to more informed debate on issues related to geological paradigms (theories), tectonic processes (plate tectonics, dynamic processes), the natural environment (landscapes, soils, erosion), natural hazards (earthquakes, volcanic eruptions, tsunamis) and the sustainable use of natural resources including soil, water, energy (oil, gas, coal, geothermal), and minerals. Many images of the Earth included in this database were collected along transects, which are long, narrow corridors across the Earth's surface. These images represent two-dimensional slices extending from the surface to depths as great as 100km. The project also includes data of older, local historic, studies which developed the current methodology, and documented the signatures of singular geological features at depth. One of the expected results of this project is to create a standard set of definitions describing images of the Earth's interior. The transects compiled include profiles that were acquired from 1961 to 2007 and comprises both on-shore and off-shore deep seismic profiles. The collected data, build around a series of transects on study areas, each of which is aimed at a number of key, representative geological targets. The data base include data from, for example: ESCI, IAM, IBERSEIS projects which is stored in a standard SEGY format (field and stack, migrated data files) and it is available to the whole scientific community.
