Study Notes
Ocean Temperature Measurement
- Ocean temperature is measured using satellites equipped with radiometers that detect thermal energy.
- Radiometers can measure temperatures at various depths, usually from just below the surface down to about 60 meters.
Sources of Heat
- The main source of heat for the ocean's surface temperature is solar radiation, primarily from the sun.
Oceans with Lower Temperatures
- Specific oceans identified as not being warm include the Atlantic Ocean and the Southern Ocean.
Methods of Measuring Ocean Temperature
- Various methods for measuring ocean temperature include buoys, thermistor chains, and ship-based instruments.
- The text does not mention the use of CTDs (Conductivity, Temperature, and Depth sensors) as a method for measuring ocean temperature.
Ocean Salinity Measurement
- Ocean salinity is typically measured using a salinometer, an instrument that assesses the salt concentration in seawater.
Importance of Ocean Salinity
- Ocean salinity helps scientists determine water density, which influences ocean circulation patterns and climate change effects.
Relation of Ocean Salinity to the Water Cycle
- Ocean salinity is crucial in understanding the water cycle as it affects evaporation rates and precipitation patterns, influencing global weather systems.
