Nick Adams was a rebel. âJohnny Yuma was a rebel. He roamed through the West.â. Those words were sung over the credits of The Rebel, a half-hour western drama from the early 1960s that is probably familiar to most baby boomers.
From Wikipedia, the free encyclopedia. A thermocline (sometimes metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below.
Photic zone. The photic zone, euphotic zone, or sunlight zone is the depth of the water in a lake or ocean that is exposed to sufficient sunlight for photosynthesis to occur. It extends from the surface down to a depth where light intensity falls to one percent of that at the surface, called the euphotic depth.
