Summary
Photosynthesis and respiratory carbon losses of freshly collected Antarctic phytoplankton were measured in incubators at 5 temperatures between-2° C and +8°C. The results were used to predict daily growth rates and to define temperature and daylength boundary conditions under which the net balance between photosynthesis and respiration would be positive and allow increases in standing stock. Whereas the Q10 of photosynthesis was 1.4–2.2, the Q10 of respiratory losses exhibited a wide range and higher maxima (2.3–12). Model calculations sugest that under ample light energy supply during long summer days, potential daily growth rates are not severely affected by the low temperatures prevailing in the Southern Ocean. If energy supply is restricted by short days and deep water column mixing, substantially reduced respiration rates at low temperatures may allow the algae to survive.
