The Role of Deep - Ocean Currents in Climate Regulation | CBCGDF Climate Change Working Group

Deep - ocean currents play a vital yet often overlooked role in climate regulation. These currents are part of the global ocean conveyor belt system.

 

Cold, dense water sinks in certain polar regions and then slowly spreads throughout the ocean depths. This process transports heat around the globe. For example, the North Atlantic Deep Water is an important component of this system. As it moves, it carries heat away from the equator towards the poles.

 

The circulation of deep - ocean currents also affects the distribution of nutrients. Upwelling zones, where deep - ocean currents bring nutrients to the surface, support rich marine ecosystems. These ecosystems, in turn, play a role in the carbon cycle. Phytoplankton in these areas absorb carbon dioxide during photosynthesis.

 

Moreover, deep - ocean currents can influence sea - level rise. Changes in their circulation patterns can cause water to be redistributed in the ocean basins. Overall, understanding and protecting the delicate balance of deep - ocean currents is essential for maintaining a stable global climate.

Unveiling the Mysteries of Cetaceans in the South China Sea: Chinese Scientists Describe Important Marine Mammal Areas (IMMAs)

Image
The world’s ocean ecosystems are facing mounting threats—climate change, marine pollution, overfishing, and habitat destruction due to human activities, to name a few. These pressures are particularly dangerous for marine mammals like cetaceans, whose survival hinges on healthy habitats and stable populations. Yet, in regions like the South China Sea, where biodiversity is exceptionally high, little research has been done to understand the needs and habitats of cetaceans. This lack of data has left a gap in our knowledge and made it challenging to establish targeted conservation strategies. Recognizing this, Chinese scientists have now set out to fill these gaps and contribute essential data to inform future policy and management, aiming to protect these vulnerable species and support the objectives of the Kunming-Montreal Global Biodiversity Framework (GBF). In a landmark study published on October 8, 2024, in Biological Conservation, Dr. Li Songhai and his team from the Institute of...
