Ocean uptake, transport, and storage of heat and carbon

Session ID#: 259678

Session Description:
Within the climate system, the ocean acts as a major reservoir of heat and carbon. These properties are transported around the ocean by a diverse array of physical and biogeochemical processes and are exchanged with the atmosphere on a wide range of timescales. Consequently, they play a major role in Earth’s energy budget, regional climate and biogeochemical dynamics and predictability, and significantly impact other components of the Earth system, such as the cryosphere and marine biology. In this broad session, we invite abstracts that address topics pertaining to any aspect of the uptake, transport and storage of heat and carbon in the ocean.

We are particularly interested in 3 broad themes:

  • What determines the rates of heat and carbon exchange with the atmosphere, and storage in the ocean interior, and what is its impact on climate?
  • What processes establish heat and carbon transport in the ocean, from the microscales of diffusive mixing to the basin and global scales of gyre and overturning circulations?
  • How has our capacity to simulate ocean heat and carbon storage improved in recent years, particularly with advances in analytical and machine learning approaches?

Through this session, we seek to bring together communities of researchers working from many perspectives to better understand the ocean's role within the wider climate system.
