โฆ Synopsis
Analyses of some 700 photosynthesis-irradiance (P-I) experiments made on natural marine phytoplankton assemblages in over six years of field work are summarized. Observed variations in P-I parameters are discussed in relation to geographical location, sample depth and temporal cycles (diel to interannual). Results suggest that P-I characteristics and therefore regional primary production are largely under physical control; temperature and light appear to be the most important environmental covariables.

Photosynthetic parameters for netplankton (>22 #m) and nanoplankton (<22 t~m) varied over similar ranges but exhibited different seasonal and geographic patterns of variation. Nanoplankton a was relatively constant (0.06 mg C [mg Chl 9 h] -a [/JE m -2 s-a]-1), but PB m (mg C [mg Chl 9 d] -a) was an
