ZOL 303 Study Guide - Midterm Guide: Electromagnetic Spectrum, Halocline, Deep Sea
Document Summary
Least dense: temp. and salinity fairly constant owing to mixing by waves and wind, to 1000 m absent, pycnocline, transition zone (18%) of ocean density, density increases with depth, strong barrier to water movement. Density is mainly dependent on temperature, salinity and pressure. The initial sg of beer is affected by composition of the wort and sugar content. Why do we see differences between these drawings: draw a diagram showing the main three density regions of the ocean, in relation to depth, at the equator, tropics and at the poles. The sky is blue because light bounce off molecules and particles in the atmosphere and blue is scattered more easily than red light. The ocean is blue because water absorbs colors in the red part of the light spectrum. As light wavelength decreases from red to blue light, so does the ability of light to penetrate water.
