Two of the most important characteristics of seawater are temperature and salinity – together they control its density, which is the major factor governing the vertical movement of ocean waters. The temperature of seawater is fixed at the sea surface by heat exchange with the atmosphere.
The factors that affects temperature are altitude, latitude and distance from sea. The height measured from sea level is called altitude. When the latitude increases, the distant from the sun also increases, so the temperature gradually decreases.
The temperature of ocean water varies by location – both in terms of latitude and depth, due to variations in solar radiation and the physical properties of water.
The temperature range extends from 30 °C (86 °F) at the sea surface to −1 °C (30.2 °F) at the seabed. Like salinity, the temperature at depth is determined by the conditions that the water encountered when it was last at the surface. In the low latitudes the temperature change from top to bottom in the oceans is large.
The controls of temperature are: Latitude (angle of Sun) - Chapter 2. Differential heating of land and water (they heat up/cool down differently) Ocean Currents.
Temperature, winds, gravitational pull of the sun, the earth and the moon, warm and cold currents are the factors that affect the movement of ocean water.
