  • Learning Objectives

    After reading this chapter you should:

    • understand the relationship between depth and pressure
    • understand the terms thermocline, pycnocline, and mixed layer
    • be able to describe temperature profiles for different regions of the ocean
    • understand how density is related to temperature, pressure, and salinity
    • understand how density changes with depth and latitude
    • understand how sound travels through water, and what physical factors impact sound transmission
    • understand the concept of the SOFAR channel
    • be familiar with the electromagnetic spectrum
    • understand the limitations of light penetration through water
