Density in the ocean is primarily determined by: temperature and salinity.
Deep currents in the ocean are cause by:
Water that sinks:
1) It is dense.
2) It is found in a few small places near the poles.
3) It moves quickly.
Water the rises:
1) Rises over the whole ocean.
2) Rises very slowly.
3) Gradually becomes less dense.
Deep water currents are important because:
1) Transport heat around the globe.
2) Affects our climate.
3) Brings nutrients from the bottom of the ocean to the surface.
Vertical Layering:
1) Where the water has come from.
2) The ocean currents.
3) How the ocean water is mixed.
Both Pictures show a slice through the Atlantic Ocean.The top picture is temperature and the bottom is salinity.
1. At 50 degrees south, estimate the temperature at the surface and the bottom.
- Surface temperature: About 1 degrees Celsius
- Bottom temperature: About 1 - 8 degrees Celsius
2. At 10 degrees south, estimate the temperature at the surface and the bottom.
- Surface temperature: About 25 degrees Celsius
- Bottom temperature: About 1 - 2 degrees Celsius
3. Is water more likely to sink near 10 degrees Celsius south or near 59 degrees Celsius south? Why?
- It is more likely to sink at 50 degrees Celsius south,because there is a lot of salinity in that area.
4. Looking at the picture of salinity, describe the different vertical layers you see.
- The bottom layers stay neutral, while at the top the water is moving and sinking.
