Your task for this unit is to discover how satellites 'see' aspects of the Earth, and what kinds of information we can gather using the principles of remote sensing 

The Task is your overall goal for the Unit.  A series of Activities will help you accomplish the Task.
The Rubric's Cube symbol suggests the task provides a challenge for you to deepen your understanding of science. 
 

 
Before I flew I was already aware of how small 
and vulnerable our planet is; 
but only when I saw it from space,
in all  its ineffable beauty and fragility, 
did I realize that human kind's most urgent task is 
to cherish and preserve it for future generations.

A bluish 'cloud' of plankton in Atlantic ocean waters near the western African coast.

Plankton find a rich feeding ground in the cold waters lying off the Namibian Desert coast. They have found a narrow
corridor of cold, nutrient-rich water in the Benguela Current along the coast. Just a few kilometers out to sea, the warmer
waters of the Atlantic do not support the plankton. The band of clouds across the top right of the frame has been created by
the interaction of the colder waters of the current and the atmosphere, so the boundary between the cold coastal waters of the
Benguela Current is clearly evident to the space observer. 

 It is one of the subtle wonders of the fragile earthly environment that plankton, and the fish that feed on them, should find
 such attractive feeding grounds sandwiched between the Namibian desert, one of the driest places on earth, and the warm,
 nutrient-poor waters of the central Atlantic.
