| Summary: | Phytoplankton blooms in antarctic waters show a strongc herence with ocea ic density fields; high biomass is observed when mixing depths are shallow. It has been hypoth esized that when phytoplankton are maintained in a stable light environment, cells photoacclimate and overcome the chronic light-limitation of growth associated with deeply mix ing water columns (Mitchell et al. 1991). Phytoplankton pho toacclimate by increasing cellular absorption capabilities (aph:m-1) and/or the quantum yield for carbon fixation (<{>:mole carbon fixed per mole photons absorbed) (Kirk 1994 |
