I suppose you are asked for atmospheric deposition over oceans ?

What is your goal ?

I can say that this topic is usually not cover properly by numerical models of the atmosphere.

For ex. Gas exchange rate can increase of a factor of ten when you have whitecaps.

Models have constant rate of exchange.

You need to define more precisely your exact interest anyways.
