Motivation
The polar areas have many unique phenomena. Circulatory systems for air and water reach the surface, as do the majority of the Earth's magnetic field lines. Thick glaciers have trapped air and water from ancient times. It is easiest to observe these phenomena near the poles.
Unfortunately, the poles are expensive places to visit, because they are distant, cold and deserted; infrastructure is sparse and the terrain is rough in polar regions (often consisting of ice blocks with crevasses between them). International cooperative programs share the costs and maximize the number of coordinated scientific observations. The IPY is the most famous example of such a cooperative program.

Famous quotes containing the word motivation:
“Self-determination has to mean that the leader is your individual gut, and heart, and mind or we’re talking about power, again, and its rather well-known impurities. Who is really going to care whether you live or die and who is going to know the most intimate motivation for your laughter and your tears is the only person to be trusted to speak for you and to decide what you will or will not do.”
—June Jordan (b. 1939)
