Coastal waters, for e:-;ample, occupy an increasing percentage of the sea as one progresses northwards from the equator, and we have already seen rhar nurrienr_~ art more plentiful o\·er contineoral shelves. These enable neritic waters to suppan productivities in the range 125-1000 mg C m·! daily, with an nerage value of the order of 500 mg C m-! daily, or some thrtt times the productivity of the adjacent areas of oceanic 26 Chapter 1 Fig. 20 The main areas of upwelling in the world ocean. ) wat~r.

This global pattern of light and heat receipt is of profound imponance to the photosynthetic potelllial of the photic zone, both via its direct effects on pholOsynthesis and via the establishment of thermoclines. If the light energy received by surface waters is sufficient for the phytoplankton to fix morc carbon per day in photosynthesis than they need to respire in that ~riod, then the heat received at the same time will be of the order of magnitude required to generale a thermocline. Thus, in open tropical waters, light intensities will permit phytoplanktonic production to last throughout the year but a deep and permanent thermocline will also persist throughout all months.
