Sea floor morphology and plio-quaternary sedimentary cover of the Mallorca channel, Balearic Islands, western Mediterranean.

A complete multibeam coverage of the sea floor of Mallorca Channel, in the western Mediterranean, was recorded during the Spanish Exclusive Economic Zone surveys in 1995, 1996 and 1997. These data, combined with previous high-resolution seismic reflection profiles, allow an assessment of the geomorp...
