This is not true.
Ocean photosynthesis produces about 50% of the oxygen in the atmosphere, but ocean respiration also consumes about the same amount. The oceans are about oxygen neutral. Same goes for the other 50%, but in land ecosystems.
'Phytoplankton are responsible for most of the transfer of carbon dioxide from the atmosphere to the ocean. Carbon dioxide is consumed during photosynthesis, and the carbon is incorporated in the phytoplankton, just as carbon is stored in the wood and leaves of a tree'.
