The oceanic Niño index (INO) is a measure of the El Niño/La Niña-Southern Oscillation (ENSO). El Niño:

"Warm water pool approaches South American coast. Absence of cold upwelling increases warming."

La Niña:

"Warm water is further west than usual."

Garbage collects in the center of the gyres.

The unit of flow for rivers and oceans is the sverdrup (Sv) = 10⁶ cubic metres per second = 0.001 km³/s = ~264 million U.S. gallons per second.
