Abstract
The present invention enables tomography data in the sea to be collected and transmitted via an artificial satellite to a ground station. Accordingly, data on the Doppler phenomenon and shift of a sound wave is also obtainable based on the temperature and density of sea water and an ocean current. This makes it possible to obtain information about a wide sea area, such as the relationship between the KUROSHIO and the El nino which is now attracting attention in relation to fishery, agriculture and abnormal weather. Hence, the present invention will be of wide application.
