thermocline

layer of rapid temperature change

salinity

3.5 % or 35 ppt

sodium chloride

the most abundant salt in the ocean

sonar

measures the depth of the ocean

temperature and salinity

affect the density of seawater

crest

the highest part of a wave

trough

tides

occur due to the gravitational pull of the sun and the moon

surface currents

the reason for their deflection is global winds, land masses, and the coriolis effect

oil

a resource that we get from the ocean
