Biogeochemical‐argo floats reveal stark latitudinal gradient in the Southern Ocean deep carbon flux driven by phytoplankton community composition

L Terrats, H Claustre, N Briggs, A Poteau… - Global …, 2023 - Wiley Online Library
The gravitational sinking of particles in the mesopelagic layer (∼ 200–1,000 m) transfers to
the deep ocean a part of atmospheric carbon fixed by phytoplankton. This process, called …

Knowledge gaps in quantifying the climate change response of biological storage of carbon in the ocean

S Henson, CA Baker, P Halloran… - Earth's …, 2024 - Wiley Online Library
The ocean is responsible for taking up approximately 25% of anthropogenic CO2 emissions
and stores> 50 times more carbon than the atmosphere. Biological processes in the ocean …
