ABSTRACT: Light availability is a critical factor regulating growth and 
photosynthesis in Antarctic phytoplankton.  Here we present
the dynamics in the optical parameters which characterize 
photoacclimation in phytoplankton during a diatom bloom.
Chl-specific absorption was not correlated with the bloom; 
however the quantum yield increased to near theoretical 
maximum values prior to the bloom.  The changes in the quantum 
yield occurred as the upper mixed layer depth shallowed, 
suggesting photoacclimation in Antarctic phytoplankton may 
be constrained by water column mixing.
