Methods, "Calcification and Photosynthesis" (from EqPac protocols)

 PI Note:   The photosynthesis and calcification technique was modified 
            according to:
                Paasche, E. and S. Brubak.  1994.  Enhanced calcification
                in the coccolithophorid Emiliania huxleyi (Haptophyceae)
                under phosphorus limitation.  Phycologia  33: 324-330.

 Nuclepore 0.4 micron membrane filters were used for all filtrations.
