Abstract: A method for determining water temperature at a random water depth using a seawater temperature vertical distribution stratum simulation model includes generating a four-layer model for seawater temperature vertical distribution, setting a maximum water depth for each layer in the generated four-layer model, generating water temperature data at equal water depth intervals by processing ocean observation data, calculating a vertical gradient of water temperatures for water depths of each layer in the four-layer model by using the generated water temperature data at equal water depth intervals, calculating a water temperature at the maximum water depth of each layer by using the set maximum water depth of each layer and the calculated vertical gradient, and calculating a model water temperature at a random water depth by using the set maximum water depth of each layer, the calculated vertical gradient, and the water temperature at the maximum water depth of each layer.

Abstract: This application relates to an apparatus 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.

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.
