An analysis was made of the relative importance of 'new' (NO:, uptake) and 'regenerated' (NH, uptake) production in the chlorophyll maximum (CHLmax) and primary productivity maximum (PPmax) layers of 152 prof~les from temperate coastal and ocean waters. In the majority of the profiles (90 of 152), the PPmax was shallower than the CHLmax. For those profiles, the magnitude of the f-ratio [NO3 uptake/(NO1 + NH,) uptake] was statistically less at the PPmax than at the CHLmax. These results offer support to the n o t ~ o n that the PPmax is fuelled largely by regenerated nutrients while the CHLmax is supported by new nutrients and is consistent with published evidence that: (1) the PPn~ax is an important site of enhanced zooplankton grazlng and nutrient regeneration, and ( 2 ) the deeper CHLrnax is at least partially a manifestation of in situ algal growth associated with the nitracline.
