Atlanic Ocean Surface Currents
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 Atlantic.
On the map below, 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 right side of each diagram).
Annual Mean Velocity Estimates of Drifter Buoys in North Atlantic 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 North Atlantic Ocean
(maybe 7-8).
Compare this diagram to the map that you drew in section #4.
Annual Mean Velocity Estimates of Drifter Buoys in Tropical Atlantic 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 equatorial Atlantic Ocean
(maybe 3-4).
Compare this diagram to the map that you drew in section #4.
Annual Mean Velocity Estimates of Drifter Buoys in South Atlantic 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 South Atlantic Ocean
(maybe 7-8).
Compare this diagram to the map that you drew in section #4.
