Marine phytoplankton take up atmospheric carbon and carry it to the seafloor when they die and sink (a process known as organic carbon sedimentation). This biological carbon pump is a powerful part of Earth's carbon cycle, ...

Dimethylsulfoniopropionate (DMSP) is a compound synthesized by marine phytoplankton for protection against the osmotic pressure of saline water. However, DMSP could also have a role in preventing freezing damage.

The ocean holds 60 times more carbon than the atmosphere and absorbs almost 30% of carbon dioxide (CO₂) emissions from human activities. This means the ocean is key to understanding the global carbon cycle and thus our ...
