I don't think the ocean produces nitrogen or oxygen for that matter. Nitrogen comes from fusion (in a star, hydrogen turns into helium, which in turn changes into heavier elements). The ocean may store some nitrogen as a dissolved gas and nitrogen in the form of compounds such as NH3 and other soluble salts.
Most of the world's oxygen is produced by phytoplankton in the ocean through the process of photosynthesis. Land plants also play a significant role in oxygen production.
The Amazon rainforest produces an estimated 20% of the world's oxygen. This equates to approximately 6% of the oxygen in the Earth's atmosphere being produced by the Amazon annually.
