Which swift-flowing surface current in a major subtropical gyre transports a large volume of warm water from the equator toward the mid-latitudes?

Kuroshio Current

In a severe warm phase of the El Niño-Southern Oscillation (ENSO), fisheries' productivity on the west coasts of the Americas is dramatically reduced. Which stage of ENSO would come just before the fisheries' collapse?

The thermocline deepens in eastern boundary currents of the Pacific Ocean subtropical gyres.

The Agulhas Current is an example of which of the following types of currents?

Western boundary current

Western intensification causes:

a large volume of water to flow within western boundary currents; a steeper slope of surface water in the western section of the gyre as compared to the eastern section of the gyre; very swift western boundary currents; the center of the gyre to be shift to the west. (all of the above)

Which method would be most appropriate for directly measuring the flow rate of the Gulf Stream?

drift bottles

which are indirect methods for measuring currents?

dynamic topography, doppler flow meters, and pressure gradients

Which of the following methods are used to measure ocean surface currents directly?

radio transmitting float bottles

The West Wind Drift is an example of which of the following types of currents?

southern boundary current

The observation of a hill of water within all subtropical gyres is an example of which of the following?

subtropical convergence

The Ekman spiral is caused by:

the wind + Coriolis effect
