The Crucial Role of the North Atlantic in Carbon Sequestration

Why is the high latitude North Atlantic a major CO2 oceanic sink?

a. Strong ocean currents

b. High levels of primary production

c. Cold waters

d. All of the above

Answer:

d. All of the above

The high latitude North Atlantic is a major CO2 oceanic sink because of its unique combination of factors - strong ocean currents, high levels of primary production, and cold waters. These elements work together to make the region an essential player in mitigating the effects of anthropogenic CO2 emissions.

The ocean currents in the North Atlantic help distribute absorbed CO2 throughout the deep ocean, while the cold waters can absorb more CO2 from the atmosphere compared to warmer waters. Additionally, the high levels of primary production mean that phytoplankton in the region have a high demand for CO2, contributing to its removal from the atmosphere.

Overall, the high latitude North Atlantic acts as a crucial CO2 oceanic sink due to its unique combination of ocean circulation patterns, cold temperatures, and high biological productivity. By understanding and appreciating the role of this region in the global carbon cycle, we can work towards better preservation and protection of our planet's natural systems.
