RANCANG BANGUN DIRFTER BUOY PENGUKURAN ARUS LAUT DENGAN METODE LAGRANGIAN
cean currents are movements of seawater masses from one place to another both vertically and horizontally that occur continuously. The movement that occurs is the result of various forces acting on the surface, column and bottom of the water. Currents play an important role in the oceanographic cycle because they affect navigational activities, shipping, delimitation of territorial or marine areas, studies of coastal dynamics, and management of marine resources. Ocean currents are also defined as the flowing movement of a mass of water due to wind, density differences or long wave movements. The Lagrangian method is a current measurement method that is carried out by observing the movement of surface currents from one point to the next within a certain time span. One application of the Lagrangian method is used on drifter buoys that measure coordinate data.
