UV exposure generally inhibits phytoplankton photosynthesis and recent results indicate that, on the average, BWFs for such inhibition are similar for mid-latitude and Antarctic phytoplankton. UV also indirectly affects phytoplankton photosynthesis through its effects on the biological availability of iron and other trace metal nutrients. 

To understand the distribution and pathways of organic material in the ocean the key question is "What happens to that 99% of the phytoplankton biomass that is remineralized between photosynthesis and burial "...

Atmosphere-ocean carbon exchange is much controlled by physical processes, including mixing of the surface and deep layers of the ocean across the thermo-cline. Biological processes favor the movement of carbon from the surface layer to deep layers and down to bottom sediments. The biological pump functions as a result of phytoplankton photosynthesis. 

As for the dependence of ko(Tw), the specific intensity of phytoplankton photosynthesis first increases as temperature change increases, reaching at some point an optimal value for p, and then, as temperature further increases it begins to decrease. Near the maximum the following approximation is often used ...

As nonconservative gases, carbon dioxide and oxygen are closely coupled to the organic carbon pool through autotrophic (e.g., photosynthesis) and heterotrophic (e.g., respiration) processes. The dominant primary producers in estuaries and the coastal ocean are benthic and pelagic microalgae (phytoplankton). The average atomic C-to-N-to-P ratio...
