Episode notes
The Ocean's Role in Climate Change
- Excess atmospheric CO2 is a major driver of global warming, and oceans play a crucial role in absorbing some of it.
- Ocean circulation affects CO2 uptake and heat transport, making it vital to understand ocean dynamics for climate predictions.
Seaweed's Carbon Storage Mechanism
- Seaweed, like trees, uses photosynthesis to convert CO2 into organic matter.
- However, seaweed's carbon storage is less permanent, requiring consideration of its fate in the ocean ecosystem.
Seaweed as a Potential Carbon Sink
- Seaweed can be a carbon sink if it reaches the deep ocean, mimicking the carbon storage of trees and soil.
- Research is exploring seaweed breakdown rates and potential impacts on deep-sea ecosystems.
