During March 1997, clockwise winds were blowing in the Coral Sea off the northeast of Austraria. The clockwise winds cause upper ocean upwelling, which supplies cool and nutrient-rich water from deep sea to the sea surface. The ocean color, chlorophyll-a, and sea-surface temperature images show the upwelling influences clearly.
