This review briefly considers two topics in primary production. In both cases time scales appear to be short (hours to days) and both have significance for ocean chemistry and physics. The first concerns implications, for studies of mixing in the surface layer, of the fact that phytoplankton “remember” their past light history. Here time scales of minutes to hours are important. The second concerns primary production as the driving force for the sinking flux of biogenic organic particles, and significant time and space scales of variability of the production of sinking particles in the surface layer. The minimum time scale of interest here appears to be 12–24 hours. |
