Sediment from the Mississippi Floods

These maps illustrate how much sediment flowed into the Gulf of Mexico during the floods on the Mississippi River in May and June 2011. The nutrient-rich sediment is expected to contribute to the development of a record dead zone this summer.

Phytoplankton Bloom off Namibia

Phytoplankton Bloom off Namibia

A flash of blue and green lit the waters off Namibia in early November 2007 as a phytoplankton bloom grew and faded in the Atlantic Ocean. The bloom stretches from north to south along hundreds of kilometers, though it is brightest in the center of this image. Such blooms are common in the coastal waters off southwest Africa where cold, nutrient-rich currents sweep north from Antarctica and interact with the coastal shelf. At the same time, the easterly trade winds push surface water away from the shore, allowing water from the ocean’s floor to rise to the surface, bringing with it iron and other material. The suffusion of nutrients from both the currents and upwelling water creates an environment where tiny surface-dwelling ocean plants (phytoplankton) thrive.
