Ocean Productivity

What is upwelling?

• When hot water and cold water mix

• When winds push the warm water and cold nutrient rich water replaces it at the surface

• When the cold nutrient rich water sinks to the bottom

• When the hot water with nutrients rises to the surface

Why is wind important for upwelling?

• Wind moves the fish

• Wind is needed to push the cold water from the surface

• Wind is needed to push the warm water away from the surface

• Wind drops the nutrients in the ocean

What is the Coriolis effect?

• The rotation of Earth that causes object to move not in a straight line like wind

• Earth's gravity that causes the winds

• Earth's gravitational pull from the moon that causes tides

• The moon causing the currents as it rotates around Earth

Why do nutrients need to be at the surface?

• Food for zooplankton

• Fertilizer for phytoplankton

• Food for salmon

• Doesn't matter

Why is upwelling important?

• Brings up fertilizer for phytoplankton to bloom

• Causes hot water to move

• Feeds the salmon

• Moves around the wind
