What is the main advantage of using satellite altimetry for observing large-scale ocean circulation patterns?
Question 3
When using remote sensing to observe 'ocean color,' what does a shift towards greener hues typically indicate?
Question 4

Question 5
A satellite instrument measures the time delay of a radar pulse reflected from the ocean surface.
