Title: Lithospheric extension in the Gulfs of Suez and Acuba and the northern Red Sea: Integrated seismic and geologic
                                                                             perspectives 
          
Short description of project:
Active seismic experiment to image crustal
structure, Moho depth, Pn anisotropy in the
northern Red Sea. Airgin shots from RV Ewing
will be recorded on both land and ocean
bottom siesmometers. Duration of shootong will
be about 2 weeks.

NOTE: This experiment overlaps with the already
funded Gulf of Suez Passive experiment, to which
PASSCAL has already committed BB instruments.
