Study Notes
Ocean and CO2 Dynamics
- Increased atmospheric CO2 triggers more CO2 release from oceans, affecting global carbon cycles.
- Oceans act as major carbon sinks, absorbing about 20% of atmospheric CO2.
Oceanic Oscillations
- The Pacific Decadal Oscillation is a natural, cyclical fluctuation that impacts ocean conditions over decades.
- The El Niño Southern Oscillation occurs due to intensified cold upwelling, influencing weather patterns.
Ocean Conveyor Belt
- The ocean conveyor belt, driven by wind currents, plays a vital role in climate regulation by redistributing heat and nutrients.
- It has an impressive flow rate of 10 million m³/sec, indicating its immense scale and impact on marine and atmospheric systems.
- Climate change is causing the ocean conveyor belt to slow down, which may disrupt global climate patterns.
Gulf Stream
- The Gulf Stream, a significant component of the Atlantic Ocean's circulation, maintains temperatures between 2°C-4°C, influencing regional climates.
Feedback Mechanisms
- Feedback loops are processes where the output of a system influences its future behavior.
- Positive feedback amplifies changes, leading to decreased outputs or destabilization of the system.
- Negative feedback works as a self-regulating mechanism, promoting stability by counteracting changes and maintaining consistent conditions.
- In a negative feedback system, an increase in output results in a subsequent decrease, aiming to restore balance.
