LONGSHORE CURRENT OBSERVATION APPARATUS AND OPERATION METHOD OF SAME

摘要

A longshore current observation device according to one embodiment of the present invention comprises: an outer casing to be set afloat on the sea and filled with a first lubrication liquid therein; an inner casing arranged inside the outer casing and provided to be afloat on the first lubrication liquid; an observation module provided to be afloat on second lubrication liquid filled in the inner casing; and a weight coupled to the bottom surface of the observation module and enabling the observation module to face upwards. Therefore, according to the present invention, the observation module is provided to be afloat on the second lubrication liquid filled in the inner casing of a dual spherical structure, in which the inner casing is arranged inside the outer casing, and includes a GPS receiver to which the location coordinates are inputted from a GPS satellite. Therefore, the observation module can carry out analysis on the basis of precise location coordinates, thereby accurately observing the motion of longshore current.
