Velocity Estimates for Surface Currents
Indian Ocean
From Drifting Buoy Data Assembly Center
Let's continue construct the
map of the annual mean velocity of the surface currents
in the global
ocean, one basin at a time, this time for the Indian Ocean.
Notice the heads on the vectors (arrows) showing direction of flow.
The length of the vector is
proportional to the speed of the current (see 25 cm/sec scale on
arrow
in upper right corner of diagram).
Annual Mean Velocity Estimates of Drifter Buoys in Indian Ocean from Drifter Data Buoy Center
Draw a representative number of the vectors, from the map above, on the map of the global ocean in section #6 of your expedition worksheet to show the motion of the surface waters in the Indian Ocean (maybe 7-8).
Compare this Diagram to Your Map in Section 5
