Ocean Carbon Uptake

What is the primary process controlling air-sea gas exchange?

• Biological activity

• Air-sea difference in gas concentrations

• Ocean temperature

• Salinity levels

What happens when atmospheric CO2 increases?

• The ocean becomes less acidic

• The ocean's chemistry remains unchanged

• The interaction with the surface ocean changes the seawater chemistry

• The ocean releases more oxygen

What is the effect of increasing CO2 on the climate?

• It has no effect

• It increases ocean salinity

• It cools the climate

• It modifies the climate, impacting ocean circulation and CO2 uptake

What is the purpose of the SOCAT data product?

• To measure ocean depth

• To provide a global dataset for biogeochemistry

• To monitor ocean temperature

• To track ocean salinity

What is a feedback loop in the context of the global carbon cycle?

• A process that has no impact on the climate

• A loop that only occurs in the atmosphere

• A cycle that only affects land ecosystems

• A system where changes in one component affect another, influencing the original change
