Title : Gulf Stream
Caption :
A subtle change in water color marks the undulatory northern edge of the Gulf Stream in this satellite image of the North Atlantic. The warm current's oligotrophic water is deep blue while the cooler, more-nutrient-rich water to the north bears the color of the phytoplankton growing there. The air above the ocean also marks the transition: it is clear above the warm Gulf Stream but hazy (or foggy) over the colder water farther north.
