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.
Epilimnion The epilimnion or surface layer is the top-most layer in a thermally stratified lake, occurring above the deeper hypolimnion. It is warmer and typically has a higher pH and higher dissolved oxygen concentration than the hypolimnion. Being exposed at the surface, it typically becomes turbulently mixed as a result of surface wind-mixing. It is also free to exchange dissolved gases such as O2 and CO2 with the atmosphere. Because this layer receives the most sunlight it contains the most phytoplankton.
