Through one of the primary carbon storage mechanisms, the biological carbon pump, phytoplankton (microscopic marine plants at the bottom of the oceanic food chain) take up CO 2 in the surface ocean ...

Without this biological carbon pump, atmospheric carbon dioxide levels would be around 50 per cent higher than they are today. But as our ocean warms, this zooplankton community is changing ...

Through diel vertical migration (DVM), zooplankton add an active transport to the otherwise passive sinking of detrital material that constitutes the biological pump. This active transport has proven ...
