Ocean Currents and Carbon Dynamics

The video provides an introduction to ocean currents, focusing on factors like wind, the Coriolis effect, and temperature. It distinguishes between surface and deep currents, explaining how surface currents are influenced by wind and the Coriolis effect, while deep currents are part of the thermohaline circulation. The video also discusses ocean gyres, their role in creating vortexes, and their environmental impact, such as garbage patches. Additionally, it covers upwelling and downwelling, highlighting their importance in nutrient distribution and carbon dioxide absorption, which are crucial for ocean and planetary health.

Which of the following is NOT a primary factor affecting ocean currents?

• Wind

• Coriolis effect

• Ocean depth

• Water temperature

What percentage of ocean water is moved by surface currents?

• 90%

• 70%

• 50%

• 10%

How does the Coriolis effect influence ocean gyres in the Northern Hemisphere?

• They spin counterclockwise

• They spin randomly

• They do not spin

• They spin clockwise

What is the primary driver of the global conveyor belt in the ocean?

• Wind

• Salinity and temperature

• Ocean depth

• Tides

Which type of current moves the majority of the ocean's water?

• Tidal currents

• Deep currents

• Coastal currents

• Surface currents

What is the main effect of upwelling on ocean ecosystems?

• Increases nutrient availability

• Decreases nutrient availability

• Reduces fish populations

• Increases water temperature

How do downwelling processes contribute to the ocean's role as a carbon sink?

• By releasing carbon dioxide into the atmosphere

• By increasing ocean salinity

• By absorbing carbon dioxide from the atmosphere

• By decreasing ocean temperature

What is the primary role of the solubility pump in the ocean?

• To capture and store carbon dioxide

• To warm the ocean surface

• To generate ocean currents

• To increase ocean salinity

How does global warming affect the ocean's ability to act as a carbon sink?

• It increases the ocean's capacity to hold carbon dioxide

• It decreases the ocean's capacity to hold carbon dioxide

• It has no effect on the ocean's carbon capacity

• It causes the ocean to release more oxygen

What happens to the ocean's ability to hold carbon dioxide as it warms?

• It increases

• It fluctuates randomly

• It decreases

• It remains the same
