Résumé :	The present volume treats the most practical methods for estimating primary production under special conditions, such as those found beneath polar ice, and the turbid conditions found in estuaries, heavily polluted waters and exceptionally eutrophic or oligotrophic waters. The determination of primary production in the world's oceans has been largely carried out by various modifications of the original carbon-14 technique proposed in 1952 by Dr Steemann Nielsen. This technique is suitable for the measurement of photosynthesis in a phytoplankton community. In some cases, however, it is apparent that photosynthesis may occur which is difficult to measure by the normal carbon-14 technique. Consequently the method requires various degrees of modification. In the present text the working group suggests ways in which the original carbon-14 technique might be modified to meet the special conditions found in some marine environments.
