Abstract
    Total annual primary production of aquatic ecosystems, comprising phytoplankton, coastal macrophytes, coral reefs, and freshwater production, is estimated at 45.8 x 1015 g C. A critical evaluation of methods used for measuring primary photoplankton productivity is given, from which it is concluded that the estimate for primary production by phytoplankton must be adjusted to yield an annual production rate of 43.5 x 1015 g C. Phytoplankton production appears to be 9 5% of total · primary production in the oceans. The small areas of coastal macrophytes, salt marshes, and estuaries contribute 3.18% of the global aquatic primary production. Also, coral reefs, although very productive, occupy too small an area to contribute significantly to aquatic primary production - only 0.65%. On the basis of present knowledge of phytoplankton physiology and evaluation of radiocarbon measurement of primary production, higher yields of oceanic phytoplankton production can be expected in the future.
