Abstract: The present invention relates to a system for marine seismic refraction survey using a remotely piloted air/water drone and a method thereof for acquiring refracted wave by providing a receiver on the air/water drone among marine seismic methods, being configured to include: a surveyvessel provided with a seismicsource generating a sound; and the air/water drone moving tethered to the surveyvessel while floating on the sea or operating under water and being capable of moving to a desired location by generating a lift force and a turning force through remote control. In addition, the system is to be used for marine seismic refraction survey by providing a hydrophone and streamer and a recording system which may record the seismic wave on an air/water drone, a remotely piloted marine observation system, whereby an effect is given to be able to acquire data of seismic refraction.

Abstract: The present invention relates generally to an apparatus and method for calculating efficient 3-dimensional (3D) traveltime by using coarse-grid mesh for a shallow depth source. More particularly, the present invention relates to an efficient 3D traveltime calculation method for a shallow depth source by combining a suppressed wave equation estimation of traveltime (SWEET) algorithm and an equivalent source distribution (ESD) algorithm, wherein the SWEET algorithm is a traveltime calculation algorithm using an damped wave equation and the ESD algorithm is for equivalently distributed sources; and to an apparatus and method for calculating efficient 3D traveltime by using coarse-grid mesh for a shallow depth source which may need less calculation time compared with that of a conventional SWEET algorithm.
