Waves, Currents, & Tides

from http://science-class.net/archive/science-class/Oceanography/waves_currents_tides.htm

The sea! the sea! the open sea! 

The blue, the fresh, the ever free! 

Without a mark, without a bound, 

It runneth the earth's wide regions round; 

It plays with the clouds; it mocks the skies; 

Or like a cradled creature lies.

Barry Cornwall
