Sea Surface Temperature, Salinity and Density

Sea Surface Temperature, Salinity and Density
Primary Topic: 
Water Cycle
Subtopics: 
Water Properties, Earth Systems, Technology, Remote Sensing, Data
Type: 
Video
Audience: 
Informal, Formal, General
Standards: 
ESS2.C
Keywords: 
sea surface temperature, salinity, density, ocean circulation
Summary: 
The animations in this group show the long-term average sea surface temperature, the long term average sea surface salinity, and the the long term average sea surface density.

The Thermohaline Circulation - The Great Ocean Conveyor Belt

The Thermohaline Circulation - The Great Ocean Conveyor Belt
Primary Topic: 
Water Cycle
Subtopics: 
Water Properties, Earth Systems, Energy Cycle
Type: 
Video
Audience: 
Informal, Formal, 9 - 12, 6 - 8
Standards: 
ESS2.C
Keywords: 
ocean, density, salinity, ocean temperature, ocean circulation, thermohaline, ocean currents
Summary: 
The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. These two regions don't mix except in certain special areas, which creates a large slow current called the thermohaline circulation.

Aquarius Ocean Circulation

Aquarius Ocean Circulation
Primary Topic: 
Water Cycle
Subtopics: 
Water Properties, Weather and Climate, Climate, Satellites, Remote Sensing
Type: 
Video
Audience: 
Informal, Formal, General
Standards: 
ESS2.A, ESS2.D, ESS3.D
Keywords: 
ocean currents, density, energy cycle, salinity, ocean temperature, climate change, wind
Summary: 
Ocean circulation plays a key role in distributing solar energy and maintaining climate, by moving heat from Earth's equator to the poles. Aquarius salinity data, combined with data from other sensors, will give us a clearer picture of how the ocean works
