Abstract: The present disclosure relates to a reverse-time migration method for marine vertical cable seismic (VCS) survey data and provides a reverse-time migration apparatus and method for vertical cable seismic (VCS) survey data using directional propagation of receiver wavefields, configured to perform equation-of-motion-based transform and inverse-transform processing on observed pressure wavefields during back-propagation of receiver wavefields to solve the problem of reflection boundary screening due to long-wavelength artifacts and avoid up/down wavefield separation to thereby simplify a migration process and improve overall quality of migration images.

Abstract: Proposed are an apparatus and a method for tracking location using a control platform of a small buoy for simulating marine pollutants, in which at least one small observation buoy floats on the ocean, and a relay buoy collects location information from the observation buoy and provides the collected location information to a weather information management server. The apparatus may include at least one observation buoy and a relay buoy, the observation buoy including a GPS receiver which receives a signal transmitted from a GPS satellite and generate location information. The apparatus may also include a communicator performing wireless transmission and reception of signals with the relay buoy, and a power source providing driving power to the GPS receiver and the communicator. The relay buoy may receive location information from the at least one observation buoy and provide the received location information to a weather information management server.
