An ocean floating drifter, which can be very quickly assembled at low cost in urgent situation, can accurately trace ocean surface currents with help of global positioning device to transmit periodically data and position information to satellites. The drifter includes a cylinder shape made of materials which can protect the electronic GPS tracker device in it. A conical shape at lower end is used to lower the impact during air drop. The weight amount at the bottom can be pre-adjusted to simulate different the wind effect during the drifting. The drifter can be kept relatively stable position during its drifting to let its GPS device reliably communicate with satellites. The drifter has special provisions to sustain impact during air drop, resist corrosion, fish-bite damage and biological fouling.
