✦ Synopsis

The use of stable isotope of carbon, 13C, for the determination of the photosynthetic rate of a marine phytoplankton population was examined. Particular concern was paid to the effects of non-phytoplanktonic organic carbon and the enrichment of inorganic carbon on the estimation of the photosynthetic rate. Photosynthetic rates determined by the a3C method showed a remarkable agreement with those determined by the ~4C method. Insitu determinations of photosynthetic rate were made in three different water types: open ocean, coastal and neritic waters, which included oligo-and mesotrophic waters, by using the 13C method estabfished.

## Abstract The photosynthetic preparation of D‐galactose‐^13^C~6~ and glycerol‐^13^C~3~ from __Gigartina corymbifera__ is described. The red marine algae biosynthesize the galactoside 2‐hydroxy‐1‐(hydroxymethyl)ethyl α‐D‐galactopyranoside (galactosylglycerol) during photosynthesis. The galactoside
