How are the currents monitored by NASA?

The bottom pressure of the Atlantic Ocean was recorded by NASA's GRACE satellites as an indication of deep ocean current speed (artist's concept). A team of NASA and university scientists has devised a new method for tracking changes in Atlantic Ocean currents, which are a major driver of global climate change, using satellite observations.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
